HIV: the facts

In 2011, there were 6,280 new diagnoses of HIV in the UK. At the end of 2011, around 96,000 people were living with HIV. Find out how to protect against HIV, and where to get tested if you're worried.

It is estimated that around a quarter of people who have HIV don't know that they have it.

Of the 6,280 new cases of HIV in 2011, around 48% were infected through heterosexual sex, and 48% through sex between men.

HIV (human immunodeficiency virus) attacks the body’s immune system (our natural defence against infection and disease). In late-stage HIV infection, also known as AIDS, the weakened immune system means the body is more vulnerable to life-threatening conditions such as pneumonia and cancer.

The virus is passed on through exchanging bodily fluids (such as semen, blood, or vaginal secretions) in the following ways:

  • unprotected sex (sex without a condom): this is the most common form of transmission, and includes vaginal, anal and oral sex 
  • sharing needles to inject drugs 
  • birth or breastfeeding: a mother can pass the virus to her baby (this can be prevented with medication) 

HIV can affect anybody. People with HIV can look and feel healthy for years. The largest number of new cases in the UK currently occurs in two main groups.  

“Around 80% of all diagnoses of HIV are among gay men and people from black African communities," says Paul Ward, deputy chief executive at the Terrence Higgins Trust.

However, people who aren't in these two groups are not risk-free. The virus can, and does, pass on through heterosexual sex.

“You can’t tell by looking at someone whether they’ve got HIV or not,” says Ward. “Whoever you are, if you’re having sex with a new partner or with someone whose HIV status you don’t know, always protect yourself by using a condom.”

If you’re worried about HIV

Get tested. There is no cure, but there is treatment that can delay the start of symptoms. “If treatment is started late, it’s less effective,” says Ward. “If you think you may have been exposed to the virus, get an HIV test.”

Don’t assume that blood tests you’ve had in the past will have detected HIV. Blood is only tested for HIV if you specifically consent to it. It can take three months for HIV to be detected in the blood, so you may be asked to come back for another test in three months' time.

You can get an HIV test at: 

  • a genitourinary medicine (GUM) or sexual health clinic
  • some GP surgeries
  • some contraception and young people’s services
  • a Fastest clinic (rapid-testing clinics run by the Terrence Higgins Trust: use the THT service finder to search for a clinic near you)
  • local community-run clinics and testing services (run by various organisations)
  • an antenatal clinic if you’re pregnant

If you have an HIV test at your GP surgery, this will go on your medical record and can be seen by your GP, practice nurse and other health professionals involved in your care.

If you go to a GUM or sexual health clinic, your records won't be seen by anyone outside the clinic, including your GP.

You may get the results in hours, days or weeks, depending on where you're tested. Find your nearest sexual health clinic.

If the test is positive

If the test is positive, you'll be referred to a specialist HIV clinic, where a number of different professionals will be able to offer you help and support. These may include:

  • a counsellor
  • a social worker
  • a dietitian
  • a dentist
  • specialist doctors with experience of treating HIV
  • emergency 'walk-in' doctors
  • a pharmacist

Your doctor can arrange blood tests to show what effect HIV is having on your immune system and discuss whether you need to start treatment. Treatment involves taking a number of tablets every day. “Think about treatment early. You need to start taking it at a point that’s right for your immune system,” says Ward. “Don’t leave it too late.”

Find out more about coping with a positive HIV test.

You will also need to think about who you want to tell about your HIV status (called disclosure) and about changes to your lifestyle that can protect your health and that of others.

You don’t have to tell past sexual partners about your positive test, but it is strongly advised that you do so they can get tested too. Staff at the clinic can contact them for you without revealing your name, if you prefer.

You can get medical help, support and counselling from the clinic, charities or other organisations.

Don't delay having a test if you think you’ve been exposed to HIV, because you need to start looking after your health as soon as possible.
