How do you know if you have HIV?

How is HIV transmitted?

The most common way of transmitting HIV in the UK is through having anal or vaginal sex without using a condom.

However, Dr Mitra Dutt explains that there are other ways of getting HIV, including sharing needles and syringes, or by transmitting it from mother to baby during pregnancy, birth or breastfeeding.

"HIV itself is found in bodily fluids of the infected person. These fluids include semen, vaginal and anal fluids, blood and breast milk. That said, it cannot be transmitted through sweat, urine or saliva," she says.

"Anyone who has sex without a condom or shares needles is at risk of getting infected with HIV."

What are the symptoms of HIV?

Dr Dutt says most people with HIV experience a short illness with flu-like symptoms. This normally occurs 2-6 weeks after HIV infection and can last for a couple of weeks.

"Once these symptoms eventually disappear, you might not notice any symptoms for many years, even though the virus can continue to damage your immune system.

"This ultimately means that many people with HIV won't realise they're infected, unless they get tested for it," she explains.

Other symptoms of HIV besides flu include:

• Feeling constantly tired.

• Feber.

• Huvudvärk.

• Swollen lymph nodes around the neck and groin.

• Skin rashes.

When should you get tested for HIV?

If you think you have been exposed to HIV, it's important to seek medical advice and to get tested as soon as possible.

Dr Dutt stresses that the only way to find out if you have HIV is to get tested, and an early diagnosis means you can access treatment sooner. This in turn can dramatically reduce your risk of becoming severely ill and passing the virus on to others.

If you start taking post-exposure prophylaxis (PEP) within 72 hours of exposure to the virus, you may be able to prevent infection altogether. PEP involves taking HIV treatment every day for one month.

There is also PrEP, which stands for pre-exposure prophylaxis - a daily pill that can protect you from HIV. With this medication, you can have a normal sexual relationship with an HIV-positive partner with reduced fear of becoming infected yourself.

Regardless of whether you test negative or positive, you may need to repeat the test between one and three months of being exposed to HIV, but you shouldn't wait this long to seek treatment.

Putting off getting tested and leaving HIV untreated can cause you to develop AIDS, which may lead to death.

What is the testing process like?

You can get tested for HIV at your GP surgery, clinics run by charities such as the Terrence Higgins Trust och sexual health clinics också.

You can also do home tests which are discreet and easy to use.

Many clinics offer finger-prick blood tests, but home testing kits vary. You may be directed to take a swab from your vagina or throat, give a urine sample, or give a finger-prick blood sample.

Dr Dutt assures that none of the tests should hurt and they should not take long to carry out. They can be done privately in your home or with a professional, depending on what's comfortable for you.

Depending on the type of test, results can take a few minutes, or a few days to come back. If your first test is positive, a second blood test will need to be carried out to confirm the result.

If your test comes back positive, you'll be referred to a specialist HIV clinic for some more tests and a discussion about your treatment options.

Can you still live a healthy life with HIV?

Thanks to advances in research and medicine, medication is available that allows you to manage an HIV diagnosis on a daily basis.

"Antiretroviral medicines come in the form of daily tablets that work by stopping the virus from replicating inside your body. This allows your immune system to repair itself and prevent further damage. That said, HIV can easily become resistant to a single form of medication, which is why most HIV-positive people take a combination of medications," says Dr Dutt.

Without treatment, your immune system can become extremely damaged. This makes you more susceptible to life-threatening illnesses, such as cancer and other severe infections.

"However, someone with HIV who is taking effective treatment can definitely live a healthy life," Dr Dutt says.

"The goal of medication is to get the level of the virus in your body so low that it's undetectable by a test. With effective treatment, you will also significantly reduce your risk of passing HIV on to others."

In fact, if your virus levels are undetectable on treatment, there is no risk of passing on the virus through sex - as the undetectable = untransmittable (U=U) campaign has sought to highlight.

HIV is a long-term illness and it can affect your life. Dr Dutt explains how those with HIV cannot donate blood or organs, join the armed forces, or visit certain countries. You may also struggle getting life insurance to cover a mortgage loan (although life insurance isn't compulsory when taking out a mortgage).

Where can you find support as you manage a long-term condition like HIV?

Being diagnosed with HIV can lead to feelings of ångest och depression, as it can be very difficult news to take in. There is still a lot of shame and stigma surrounding HIV. Stereotypes from the 1980s about HIV and AIDS being a death sentence often prevent people from getting tested our of fear. Depression is actually twice as common in people with HIV; however, help is available and you don't have to face this by yourself.

Counselling and psychotherapy can help you to understand underlying issues and make longer-term changes to shift your perspective on life. Your GP will be able to help you find a trained counsellor or psychologist to talk to. You may also benefit from antidepressiva or anti-anxiety medication, which your doctor can prescribe.

Alternatively, there are specialist helplines designed to help people with HIV.
