HIV is a virus most commonly caught by having unprotected sex or by sharing infected needles and other injecting equipment to inject drugs.
HIV stands for human immunodeficiency virus. The virus attacks the immune system, and weakens your ability to fight infections and disease.
AIDS is the final stage of HIV infection, when your body can no longer fight life-threatening infections.
There is no cure for HIV, but there are treatments to enable most people with the virus to live a long and healthy life.
HIV is not spread as easily as some other viruses, such as colds or flu.
HIV is found in the body fluids of an infected person, which includes semen and vaginal fluids, blood, inside the anus and breast milk.
HIV cannot be transmitted by saliva alone. But the saliva of a person with HIV can be infectious if it contains blood or other body fluids.
The most common way of getting HIV in the UK is by unprotected sexual contact with a person who has HIV. This can include vaginal, anal and oral sex. According to statistics from the Health Protection Agency, 95% of those diagnosed with HIV in the UK in 2010 acquired HIV as a result of sexual contact.
Other ways of getting HIV include:

The only way to find out if you have HIV is to have an HIV test.
If you think you might be at risk of HIV, you should have a test immediately. The earlier HIV is detected, the more likely it is that treatment will be successful.
Emergency anti-HIV medication called PEP (post-exposure prophylaxis) may stop you becoming infected, but treatment must be started within three days of coming into contact with the virus.
It can take several weeks after infection before the virus is picked up in testing, so after your initial test you will be advised to have another one a few weeks later.
There are a number of places you can get an HIV test, including your doctor surgery and sexual health clinics and clinics run by the Terrence Higgins Trust.
You may get the results in hours, days or weeks, depending on where you were tested.
If your test is positive you will be referred to a specialist HIV clinic where you'll have more blood tests to show what effect HIV is having on your immune system and be able to discuss treatment options.
Gay and bisexual men
HIV is disproportionately common among men who have sex with men.
NICE recommends that annual HIV tests be offered to all men who have sex with men, and more frequent testing be offered to those at higher risk due to multiple partners or unsafe sexual practices.
Although there is no cure for HIV, treatments are much more successful than they used to be, enabling people with HIV to lead as normal a life as possible.
Medication, known as antiretrovirals, works by slowing down the damage the virus does to the immune system. These medicines come in the form of tablets, which need to be taken every day.
You will be encouraged to take regular exercise, eat a healthy diet, stop smoking and have yearly flu jabs and five-yearly pneumococcal vaccinations to minimise the risk of getting serious illnesses.
Someone with HIV is said to have AIDS when investigations show their immune system has stopped working and they develop life-threatening illnesses such as cancer.

HIV can affect anybody.
The World Health Organization estimates that around 34 million people in the world are living with HIV.
The virus is particularly widespread in sub-Saharan African countries, such as South Africa, Zimbabwe and Mozambique.

Most cases of HIV are caused by having unprotected sex with a person who has HIV.
A person with HIV can pass the virus to others whether or not they have any symptoms. People with HIV are more infectious in the weeks following infection.
The main routes of transmission are unprotected vaginal and anal sex. although it is possible to catch HIV through unprotected oral sex with a person who has HIV, but the risk is much lower than that for vaginal and anal sex.
If a person performing oral sex has HIV, transmission of the virus can occur if blood from their mouth passes into the body of the other person. If the person receiving oral sex has HIV, transmission can occur if their semen, vaginal fluid or blood gets into the mouth of the other person.
Other ways of getting HIV include:
HIV is not passed on easily from one person to another. The virus does not spread through the air like cold and flu viruses.
HIV lives in the blood and in some body fluids. To get HIV, one of these fluids from someone with HIV has to get into your blood.
The body fluids that contain enough HIV to infect someone are:
Other body fluids, like saliva, sweat or urine, do not contain enough of the virus to infect another person.
The main ways the virus enters the bloodstream are:
You cannot catch HIV from an infected person from:
If someone with HIV has bleeding in their mouth, such as from open ulcers, sores or cuts, there is a very low chance that this could lead to transmission during open-mouthed kissing. HIV spread through biting is very rare, with only a couple of documented cases.
HIV infects cells of the immune system, the body’s defence system, making it unable to fight off infections.
The virus enters the immune system’s CD4 cells, which protect the body against various bacteria, viruses and other germs.
It uses the CD4 cells to make thousands of copies of itself. These copies then leave the CD4 cells, killing them in the process.
This process continues until eventually the number of CD4 cells, also called your CD4 count, drops so low that your immune system stops working.
This can take about 10 years, during which time you will feel and appear well. Find out more about the symptoms of HIV.
People who are at high risk of catching HIV include:
Mick Mason, who has haemophilia, caught HIV and hepatitis in the early 1980s from contaminated blood products.
“I discovered I had HIV by chance in 1985 when I was sent a double-sided diet sheet by the hospital. On one side it said, ‘This is what to eat if you are HIV positive’ and on the other, ‘This is what to eat if you have AIDS’. They just assumed that somebody had told me that I had HIV.
"I phoned the haematology unit, who refused to talk about it over the phone. In the end, I had a two-minute appointment with the consultant, who said: “You have got hepatitis B and HIV. Go away and enjoy yourself but don’t have sex.” I was just 18 and it didn't seem real.
"In 1985, HIV was a death sentence. There was no support or counselling. You were left to get on with it. My way of coping was to try to forget about it. I would go to work then out to the pub and stay there until I was chucked out. I didn’t imagine I would ever meet anyone, let alone get married.
"I never really thought about death or dying. I suppose I just stuck my head in the sand. I told my mother, who thought it was the end of the world, and a few close relatives, but I didn’t tell any of my friends for three or four years.
"I met my wife, Caroline, in 1989. I didn’t tell her I had HIV at first as I was afraid she would reject me. I didn't know that my cousin, whom I met Caroline through, had already told her. At first we were just friends, but one night as we were becoming closer she asked me about it.
"I was so afraid she would push me away that I tried to deny it, but eventually I told her that I had HIV and she may as well leave now. But she didn’t and we talked and cried about it until about 4am. She didn’t seem that shocked, but was very upset and felt the injustice of it all. I think she had already read up on HIV before she confronted me so had some knowledge.
"We’ve always had protected sex but my HIV status has never stopped us doing anything. It’s important to always protect yourself and the other person. We are all responsible for our own sexual health and if you have HIV, it is your responsibility to always use a condom.
"We got married in August 1990. Caroline told her parents about my HIV as I chickened out of the task. They were shocked and devastated but were fully supportive of our relationship. At first we lived from birthday to birthday and Christmas to Christmas. I would go to the hospital every two or three months and they would say, ‘You’ve got another two or three years', until around the mid-90s.
"But there was to be another blow. In 1994, I was sent a letter telling me that I had tested positive for hepatitis C. Understandably, I felt very angry but not really that surprised. I suspect they knew I had hep C back in the early 80s. I had treatment for it but, unfortunately, it failed. I approached the treatment thinking that it wouldn’t work. That way, I wouldn’t be too disappointed when it didn’t. So I really wasn’t too bothered.
"I decided to start treatment for my HIV in 1996 because we wanted to try for a baby. I think I may be one of the lucky ones. I never had any major side effects. I had some internal bleeding with one of the drugs but they changed them and I was fine. Well, I say fine, but I just had what I would call the normal side effects that most people get: nausea, joint pain, lethargy, dodgy bowel movements. We’ve had several tries at fertility treatment but without success and have now decided to give up.
"I have had a few life-threatening moments. They make you see things in a different light. Some of these have been caused by my haemophilia, which was a shock as I had spent so many years worrying and concentrating on my HIV status that I had forgotten my haemophilia could kill me.
"Having HIV was occasionally debilitating, physically and mentally. At one point, I had a problem with the muscles in my arms, which was put down to the HIV. I couldn’t raise my arms above my head. I couldn’t hold anything tight including cups, or even peel a potato. I have had three bouts of intussusception, which again, I was told, was down to the HIV. But it’s not a death sentence any more. As a haemophiliac, I tend to be seen as a victim, unlike people who have contracted HIV sexually, who tend to be blamed. But the truth is, it is no one’s fault – no one set out to give me HIV.
"Having HIV is not the end of the world, although I do have dark moments, especially if things go wrong. It does affect my life. I can’t get life insurance, although I have been able to get a mortgage. There is also the issue of who to tell. Due to the stigma that comes with HIV, you have to be careful who you tell. But to be honest, who really needs to know? If you were asthmatic, you wouldn’t tell everyone, so why would you if you had HIV? In the past I didn’t tell employers, although these days I am open about it.
"We used to foster teenagers and the team knew about my HIV status. When deciding whether to tell people, think about who needs to know. Obviously your partner and your children and maybe a close friend or two, but people who are not close don’t need to know. You are not putting them at risk.
"The more people who are open about HIV, the less stigma there will be. I went public with my condition in 2000 and am at the point now where I really don’t care who knows about my status. I often do radio, television and newspaper interviews. I feel that unless you are open about your status, nothing will really change. If you hide your HIV status in a dark corner, that's where you'll feel you are.”
There is no cure for HIV, but treatments are much more successful than they used to be, enabling people with the virus to stay healthy and live longer.
If you think you have been exposed to the virus within the last 72 hours (three days), anti-HIV medication may stop you becoming infected.
For it to be effective, the medication, called post-exposure prophylaxis or PEP, must be started within 72 hours of coming into contact with the virus.
The quicker PEP is started the better, ideally within hours of coming into contact with HIV. The longer the wait, the less chance of it being effective.
PEP has been misleadingly popularised as a “morning-after pill” for HIV – a reference to the emergency pill women can take to prevent getting pregnant.
But the description is not accurate. PEP is a month-long treatment, which has serious side effects and is not guaranteed to work. The treatment involves taking the same drugs prescribed to people who have tested positive for HIV.
You may be able to get PEP from:
Not all these places in every part of the country will have PEP or be able to give it. Doctors usually do not provide PEP.

If you are diagnosed with HIV, you will have regular blood tests to monitor the progress of the virus before starting treatment.
You will not normally need to start treatment until the virus has begun weakening your immune system.
This is determined by mainly by measuring your levels of CD4, which are infection-fighting cells, in your blood.
Treatment is usually recommended to begin when your CD4 count falls to 350 or below, whether or not you have any symptoms. Treatment is also recommended to as soon as possible if your CD4 count is getting close to 350.
The aim of the treatment is to reduce the level of HIV in the blood and prevent or delay any HIV-related illnesses.
Treatment is recommended to begin at any CD4 count if you are on radiotherapy or chemotherapy that will suppress your immune system, or if you have been diagnosed with certain other illnesses, including:
HIV is treated with antiretrovirals (ARVs), which work against the HIV infection by slowing down the spread of the virus in the body.
A combination of ARVs is used because HIV can quickly adapt and become resistant to one single ARV.
Patients tend to take three or more types of ARV medication. This is known as combination therapy or highly active antiretroviral therapy (HAART).
Some antiretroviral drugs have been combined into one pill, known as a "fixed dose combination". This means that the most common treatments for people just diagnosed with HIV involve taking just one or two pills a day.
Different combinations of ARVs work for different people so the medicine you take will be individual to you.
Once HIV treatment is started, you will probably need to take the medication for the rest of your life. For the treatment to be effective, it will need to be taken on time, every time.
Many of the medicines used to treat HIV can react in unpredictable ways if you take them with other types of medicines.
These include herbal remedies such as St John's Wort, recreational drugs such as cocaine, and some over-the-counter medicines. Always check with clinic staff or your doctor before taking any other medicines.

ARV treatment is available to prevent a pregnant woman from passing HIV to her child.
Without treatment, there is a one in four chance that your baby will develop HIV. With treatment, the risk is less than one in a hundred.
Advances in treatment mean there is no increased risk of passing the virus to your baby with a normal delivery. However, for some women, a caesarean section may still be recommended.
If you have HIV, do not breastfeed your baby because the virus can be transmitted through breast milk.
If you or your partner has HIV, fertility treatments, such as sperm washing, may be available that will allow you to conceive a child without putting either of you at risk of infection.
HIV treatment only works if you take your pills on time, every time. Missing even a few doses will increase the risk of your treatment not working.
You will need to develop a daily routine to fit your treatment plan around your lifestyle.

HIV treatment can have unpleasant side effects. If you get serious side effects (which is uncommon) you may need to try a different combination of ARVs.
Common side effects include:

People with HIV can get treated by their own doctor or by a specialist at an HIV clinic or a GUM clinic.
Services, including support organisations, may work together to provide specialist care and emotional support.
Tina Middleton caught HIV when she was just 20 years old from a partner with haemophilia.
"I had been in a relationship with someone with haemophilia and didn’t know he had HIV until I got pregnant. I had a test straight away and, at first, it seemed all right as it came back negative. However, in March 1992 when I was eight months pregnant, I had another test, which was positive. It was the worst possible news.
"I didn’t tell anyone. My main focus was just to get through the pregnancy. Not much was known then about HIV in pregnancy and when I came to deliver my baby, the staff were all gowned and masked up. It was horrible. It was not known that a caesarean birth is safer so I had a normal delivery and I was then put in a ward on my own, away from the other mothers. I had to tell my mother and my best friend as they wanted to know why the nurses were all wearing masks. They were shocked and I wasn’t able to reassure them as I knew so little myself. The attitude was, 'Keep it quiet and don’t tell anyone else'.
"The months following my son Adam’s birth were awful. Looking back now, I don’t know how I got through it. I was suicidal. I had split up with my partner by then (not because of the HIV) and all I used to do was cry. I would look over the balcony of my flat and think about jumping off. Other people found out without me telling them and some of my friends didn’t want to know me. Others asked if I was a sex worker.
"When I went to the HIV clinic, the staff were fantastic, really supportive, but at that time HIV was considered to be a disease of gay men and I was the only woman there. I felt very isolated and low.
"Five months after my son was born, I met up with Andrew, who I’d known for a long time. He knew about my HIV status and he and his family were accepting. We got married and three years later I had my second son, Mark, through self-insemination to avoid passing the virus on to my husband. Life became better, but I was still being told I only had eight to 10 years to live, so I put my life on hold.
"Things started to change in 2001 when I split up with Andrew. I realised I had to be independent, for myself and for my sons. And by then, HIV treatment had changed. There was medication, and I was healthy. People were more aware that it wasn’t a death sentence.
"For years, I didn’t want to talk about having HIV, but today I am much more open and I no longer feel isolated. I have had a couple of bouts of serious illness and have disclosed my HIV status to friends, who have been accepting and wanted to know how best to support me.
"After I split up with Andrew, I had to learn how to make new relationships. The way I approach it is to get to know potential partners as friends first so they get to know me as a person. I have never had sex without telling them first but that is a huge pressure. It is hard and it never gets any easier. The week before I tell them, I hardly sleep for fear of how they will react. I always worry they are going to turn nasty, although, in fact, I have been very lucky and none of them has rejected me.
"I’m now in another long-term relationship and my current partner, Martin, is great. Before we slept together, I gave him information and leaflets and told him about PEP (post-exposure prophylaxis).
"HIV is part of our lives but we don’t really talk about it much, although he does nag me if I'm late taking my tablets. It's a nuisance having to use condoms all the time. It means that every time we have sex, it comes to mind and we both wish it didn’t have to. But apart from that, it doesn’t affect our lives that much.
"I’ve been on medication since 2001, but have struggled a lot with side effects. After a couple of years, I found I was resistant to most of the drugs I was taking. Last year, I decided to have a treatment break, which was originally to be three months but ended up being six months.
"During that time, I became ill with bronchitis and subsequently a type of pneumonia, called pneumocystis pneumonia or PCP, which often affects people with HIV. My life was touch and go for a while but I’m better now, although my energy levels can be low and I have had continued problems with breathing.
"I’m now on new medication, and the side effects have stabilised. My CD4 count has improved, although it is still on the low side, and my viral load is better. Having said that, I don’t go by my CD4 levels but by how I feel. I know myself better than any doctors do, and today I feel healthy and fine.
"My sons still don’t know I have HIV so that is the next hurdle. Part of me wants to pre-plan it so there is someone there who is supportive, but part of me thinks I will just tell them when the time seems right. I have worked for the Terrence Higgins Trust for four years now, which means they are both well aware of HIV and the issues surrounding it and are very accepting, so I don’t think telling them will be a problem.
"I’m really optimistic about the future. I have got my own mortgage and I love my life and the work I do. I know there are still lots of challenges to overcome, but I have a lot to live for and a lot still to do. It's good to be able to share my experiences with other people.
"I often go out and give talks about HIV as part of my work and people are frequently surprised when I say I have been living with it for 15 years. But it’s true that you can’t put a face on HIV. In a strange way, if it wasn't for my HIV, I wouldn’t be who and where I am today."
Most people who are infected with HIV experience a short, flu-like illness that occurs two to six weeks after infection. After this, HIV often causes no symptoms for several years.
The flu-like illness that often occurs a few weeks after HIV infection is also known as seroconversion illness. It's estimated that up to 80% of people who are infected with HIV experience this illness.
The most common symptoms are:
Other symptoms can include:
The symptoms, which can last up to four weeks, are a sign that your immune system is putting up a fight against the virus.
These symptoms can all be caused by conditions other than HIV, and do not mean you have the virus.
However, if you have several of these symptoms, and you think you have been at risk of HIV infection, you should get an HIV test.
After the initial symptoms disappear, HIV will often not cause any further symptoms for many years.
During this time, known as asymptomatic HIV infection, the virus continues to spread and damage your immune system. This process can take about 10 years, during which you will feel and appear well.

If left untreated, HIV will weaken your ability to fight infection so much that you become vulnerable to serious illnesses.
This stage of infection is known as AIDS, although doctors now prefer to use the term late-stage HIV infection.
Typically, a person with late-stage HIV infection has:
At this stage, you are at increased risk of life-threatening illnesses such as tuberculosis, pneumonia and some cancers. Many of these, though serious, can be treated and your health is likely to improve if you start HIV treatment.

Sarah has HIV. She describes her pregnancy and the steps she had to take to ensure she’d have a healthy baby.
An expert explains what HIV is and how to avoid passing it on to your unborn child.
The main way to prevent HIV infection is to avoid activities that put you at risk, such as unprotected sex and sharing needles and other injecting equipment.
If you have HIV you can pass it on to others if you have sex without a condom, or share infected needles, syringes, or other injecting equipment.
It is important to continue to practise safer sex even if you and your sexual partner both have HIV. This is because you can catch another strain of the virus that your HIV medication may not be able to control.
Intentionally or recklessly transmitting HIV to another person is a criminal offence. People have been found guilty of passing on HIV and sent to prison.
HIV can be spread by having unprotected vaginal or anal sex. There is also a risk of transmission through oral sex, but this risk is much lower.
HIV can also be caught from sharing sex toys with someone infected with HIV.
See causes of HIV for more on transmission of HIV.
The best way to prevent HIV and other sexually transmitted infections (STIs)is to use a condom for penetrative sex and a dental dam for oral sex.
Condoms come in a variety of shapes, colours, textures, materials and flavours. Both male and female condoms are available.
A condom is the most effective form of protection against HIV and other STIs. They can be used for vaginal and anal sex, and oral sex performed on men.
HIV can be passed on before ejaculation, through pre-come and vaginal secretions, and from the anus.
It is very important that condoms are put on before any sexual contact occurs between the penis, vagina, mouth or anus.
Lubricant, or lube, is often used to enhance sexual pleasure and safety, by adding moisture to either the vagina or anus during sex.
Lubricant can make sex safer by reducing the risk of vaginal or anal tears caused by dryness or friction, and it can also prevent a condom from tearing.
Only water-based lubricant (such as K-Y Jelly) rather than an oil-based lubricant (such as Vaseline or massage and baby oil) should be used with condoms.
Oil-based lubricants weaken the latex in condoms and can cause them to break or tear.
A dental dam is a small sheet of latex that works as a barrier between the mouth and the vagina or anus to reduce the risk of STIs during oral sex.
Dental dams are available in a variety of flavours and colours, and typically come in two forms:
It is important that dams are only used once, the same side of the dam is always kept against the body, and a new dam is used if a new area of the body is being stimulated. A dam should never be moved from the vagina to the anus or vice versa.
If you inject drugs, don't share needles or syringes, or other injecting equipment such as spoons and swabs, as this could expose you to HIV and other viruses found in the blood, such as hepatitis C.
Many local authorities and pharmacies offer needle exchange programmes, where used needles can be exchanged for clean ones.
If you are a heroin user, consider enrolling in a methadone programme. Methadone can be taken as a liquid, so it reduces your risk of getting HIV.
A doctor or drug counsellor should be able to advise you about both needle exchange programmes and methadone programmes.
Clint was diagnosed with HIV when he was 17. The infection progressed to AIDS within six months, which is unusually rapid. In this video, filmed in 2008, he talks about getting the diagnosis and living with AIDS. Clint died on April 4 2010, aged 31.
Michael Edwards contracted HIV in 1990. He is now 62 and is still working and leading a healthy life.
“The first sign was a bad dose of flu. Like me, my doctor is gay and he suspected that I had contracted HIV. I flew down to St Mary’s Hospital and had a test, which was positive. Unusually, I contracted HIV through oral sex, probably because I had bleeding gums.
"I work at the London Lighthouse, an HIV and AIDS charity, and I think because of that I didn’t have the same pressures that many people do. The main issue for me was telling my family. My father had died by the time I was diagnosed. I told my sister, but I was worried about telling my mum. Shortly afterwards, however, she got ill and died so she never had to know.
"At that time, before effective medication, people were dying all the time and I didn’t have much time to think about my own situation. I started on medication in the late 90s. It took me a year to decide to go on it but I have had no regrets. My CD4 cell count immediately went down and my viral load became undetectable, which meant no virus could be detected in my blood. I was lucky in that I didn’t have any major side effects. The only thing I noticed was that if I didn’t have breakfast, I felt sick.
"I am now on my second lot of treatment, having had a treatment break of a year, and I am finding adherence more difficult. The main problem is nausea, but I find the more I eat, the better I respond.
"Coping with HIV is very much a matter of attitude. There is still a stigma attached to it, maybe not as much in the 1980s, but it is still there. When I do talks, I always say, 'It’s not just a question of sleeping around. It’s like getting pregnant: if you have sex, the risk is there.' We have rotten sex education in this country. We need to get better and make sure that kids are informed. Parents need to realise that their children are having sex and to make sure that they are doing it safely and have the information to protect themselves.
"As far as telling sexual partners is concerned, I find it better to tell them I have HIV straight away rather than get a couple of months down the line and have them find out. Some people do reject you and that can be hard, but I still believe it is better to be open. Some people find it easier with internet dating services to put their HIV status on their profile so they don’t have to do it face to face. Different things work for different people. As for me, I don’t care who knows.
"Things have moved on a lot since I was diagnosed. These days in the West, although not in Africa, people are living with HIV rather than dying from it. In the old days, the main challenge was deciding who to tell. It was difficult, especially as some of my friends didn’t want to know when they discovered. As the problem got more widespread and more people had HIV, however, many of those who wouldn’t give me the time of day when I was first diagnosed changed their attitude.
"There is still is a certain amount of prejudice within the gay community. Things are getting better, but they haven’t changed completely and they won’t until people change their attitudes and condom wearing becomes second nature.
"With the advent of medication, a lot of complacency exists. Some people have the attitude that you just take a pill and you are OK. It isn’t quite like that. We have to get across the seriousness of HIV and make people realise that it is not just a problem that affects gay men. It’s everybody’s problem.”
Being diagnosed with HIV can be very distressing, and feelings of anxiety or depression are common. Your HIV clinic can provide you with counselling so that you can fully discuss your condition and your concerns.
You may find it helpful to talk to a trained counsellor or psychologist, or to someone at a specialist helpline. Your HIV clinic will have information on these.
Some people find it helpful to talk to other people who have HIV, either at a local support group or in an internet chatroom.

If you have HIV, it is important that your current sexual partner or any sexual partners you have had since being exposed to infection are tested and treated.
If you do not tell your sexual partners and you have unsafe sex and infect someone, they could prosecute you.
Some people can feel angry, upset or embarrassed about discussing HIV with their current or former partners. Discuss your concerns with your doctor or the clinic staff. They will be able to advise you about who should be contacted and the best way to contact them.
Nobody can force you to tell any of your partners about your HIV, but it is strongly recommended that you do. Left untested and untreated, HIV can have devastating consequences and will eventually lead to death.
There is no legal obligation to tell your employer that you have HIV, unless you work in healthcare and are carrying out invasive procedures. In this case, you must tell your occupational health physician and avoid performing invasive procedures.
There is also no law to stop your employer from asking you if you have HIV.
However, the Equality Act 2010 places restrictions on the health questions that employers can ask during a job application process. Employers are allowed to ask health questions to help them decide whether you can carry out tasks that are essential for the job, and for a limited number of other reasons.
If you are an employee with HIV, you may worry that if you do tell your employer, your HIV status will become public knowledge or that you may be discriminated against. On the other hand, if your boss is supportive, telling them may make it easier for adjustments to be made to your workload or for you to have time off.
The HIV organisations below have lots of information and can advise you on these and other work-related issues.
If you have HIV and become pregnant, contact your HIV clinic. This is important because:
Without treatment, there is a one in four chance that your baby will develop HIV. With treatment, the risk is less than one in a hundred.
Advances in treatment mean that a normal delivery will not usually increase the risk of transmission from mother to baby for women who have an undetectable viral count and whose HIV is well managed. For some women, a caesarean section may still be recommended.
Discuss the risks and benefits of each delivery method with the staff at your HIV clinic. The final decision about how your baby is delivered is yours, and unless any unforeseen complications make a caesarean section necessary, staff will respect that decision.
If you have HIV, do not breastfeed your baby because the virus can be transmitted through breast milk.
If you or your partner has HIV, fertility treatments may be available that will allow you to conceive a child without putting either of you at risk of infection.

If your CD4 count drops below 200, you will be at risk of catching many different types of infection. Infections that 'take advantage' of an HIV-weakened immune system are known as opportunistic infections. However, if you stick to your HIV therapy, the likelihood of developing an opportunistic infection remains low.
The four main types of opportunistic infections are:
People with advanced HIV also have a higher risk of developing some forms of cancer, such as lymphoma (cancer of the lymph system).
Pneumonia is a bacterial infection of the lungs. It can often develop as a complication of other infections, such as a cold or flu. Left untreated, pneumonia can be fatal because the infection can spread through your blood.
Pneumonia can be treated using antibiotics. There is also a vaccine that can protect you against many of the bacteria that can cause pneumonia. People living with HIV are recommended to receive annual vaccinations.
TB is another bacterial infection of the lung. Globally, it is the leading cause of death for people who are HIV positive. TB can be treated using antibiotics, but some strains of bacteria have developed resistance to this medicine, and these can be more difficult to treat.
Hepatitis is a viral infection that can cause damage to your liver. This can increase your risk of developing liver cancer. There are three main types of hepatitis: hepatitis A, hepatitis B and hepatitis C.
Vaccines are available for hepatitis A and hepatitis B, but not for hepatitis C. Avoiding sharing needles and using a condom are the best ways to prevent hepatitis.
Candidiasis is a fungal infection that is common in people living with HIV. It causes a thick, white coating to appear on the inside of the mouth, tongue, throat or vagina.
Though rarely serious, candidiasis can be both embarrassing and painful. It can be treated with antifungal creams.
Tell the staff at your HIV clinic if you have repeated bouts of candidiasis because it could be a sign of a low CD4 count.
PCP is a fungal infection of the lungs, which can be life-threatening if it is not treated promptly. Before the advances in anti-HIV medicines, PCP was the leading cause of death among those with HIV in the developed world.
Symptoms of PCP include:
Report any symptoms of PCP straight away because the condition can suddenly worsen without warning. PCP can be treated with antibiotics and, if your CD4 count drops below 200, you may be given antibiotics to prevent a PCP infection.
People with advanced HIV have an increased risk of developing cancer. It is estimated that somebody with untreated late-stage HIV infection (AIDS) is 100 times more likely to develop cancer than somebody without the condition. However, with treatment, the risk of getting cancer is much the same as that of the general population.
The two most common cancers to affect people with HIV are lymphoma and Kaposi's sarcoma. Lymphoma is a cancer of the lymphatic system (a network of glands that makes up part of our immune system). Kaposi's sarcoma can cause lesions to grow on your skin, and can also affect your internal organs.
Many people living with HIV have no signs and symptoms at all.
People who have recently been infected with HIV often experience a short, flu-like illness two to six weeks after infection. Symptoms include fever, sore throat, and body rash. See symptoms of HIV for more information.
You can only be certain you have HIV if you have an HIV test.
If you think you might be at risk, you should have a test immediately. The earlier HIV is detected, the more likely it is that treatment will be successful.
If you do have HIV, delaying treatment will allow the virus to spread in your system and damage your health.
The sooner you get tested, the sooner you can start life-saving treatment and avoid spreading the virus to someone else.
The most common form of HIV test is a blood test, in which a small amount of blood is taken and examined.
In some areas, saliva tests are available. In this test, a sample of saliva is taken using a mouth swab. In some areas dried blood spot tests are available, in which the finger or heel is pricked and a spot of blood is blotted onto filter paper.
It can take between three weeks and three months after you have been infected with HIV for the virus to show up in testing.
If your most recent risk of getting HIV was within the last three months you can test straight away, but you will be advised to have another one a few weeks later.
If the test finds no signs of infection, then your test result is “negative”. If the HIV virus has been found in your blood then the test result is “positive”.
Before someone is given a positive result the blood is tested several times to be completely sure.
If you test positive for HIV, you will undergo a number of tests to monitor the progress of the infection to work out when HIV treatment should be started.
