HIV in the UK

The first reported case of HIV in the UK was in the early 1980s and since then a lot has changed. Here we answer some common questions about HIV in the UK.

If you live in England you can find more information, including information about HIV in your local area, on the interactive website HIV Lens.

Data for Northern Ireland hasn’t been available since 2022.

How common is HIV in the UK?

In 2024, 111,843 people accessed HIV care across England, Scotland, and Wales. This is less than 2 in every 1000 people.

Around 93% of these people live in England and of those, 38% live in London.

How many people are diagnosed with HIV each year?

In 2024, there were 2969 people diagnosed with HIV in England, Scotland, and Wales. The number of people being newly diagnosed has been fairly stable for the last 3 years.

Most people with HIV (95%) know their status because they have been diagnosed. But it’s thought that around 5% of people with HIV haven’t been diagnosed. This is around 6000 people.

What are the most common ways HIV is passed on?

Sexual transmission was the reason for most of the new HIV diagnoses in the UK in 2024. Around 62% of these diagnoses were from heterosexual sex, and around 38% were from sex between men.

HIV can also be passed on by injecting drugs and from mother to baby during childbirth, but these are much less common.

How many people diagnosed with HIV in the UK are receiving treatment?

Almost all (99%) of the people who have been diagnosed with HIV in England, Scotland, and Wales are receiving treatment.

Around 98% of people who are receiving treatment have an undetectable viral load.

Having an undetectable viral load means that the virus can’t replicate. This is important because it allows your immune system to get stronger and fight off infections.

It also means there isn’t enough HIV in your body fluids to pass on HIV to somebody else during sex. This is often referred to as ‘undetectable equals untransmittable’ or ‘U=U’.

How does HIV affect different groups of people?

Anyone can get HIV, but some groups of people are more affected than others.

In England, Scotland, and Wales, gay and bisexual men make up around 46% of the people who access HIV care. However, the number of new diagnoses in this group has been falling significantly. This is because of the high uptake of HIV testing, prompt treatment and the use of PrEP (medication to prevent HIV). In 2015, gay and bisexual men made up around 50% of the people newly diagnosed with HIV, but in 2024 that had fallen to 30%.

In general, more men than women are living with HIV. Of everybody accessing HIV care in England, Scotland, and Wales in 2024, 66% were men and 33% were women. Around 0.5% identified as another gender.

Black African people are also disproportionately affected by HIV. In 2024, they made up about 31% of the people accessing HIV care and around 32% of new diagnoses, but only around 2% of the general UK population.

Which age group is most affected by HIV?

Around 47% of people accessing HIV care in England, Scotland, and Wales are between 25 and 49. Because many people are now living longer, healthier lives with HIV, the age of people accessing care is increasing. In 2012, only 25% were 50 or over, but in 2024 around 52% were.

In England, Scotland, and Wales, the majority (68%) of new HIV diagnoses are in people aged between 25 and 49. But the number of new diagnoses in people over 50 has been increasing since 2015. They made up around 22% of the people diagnosed with HIV in 2024.

People under 25 only make up around 10% of new diagnoses.

Who is most likely to be diagnosed late?

In 2024 around 42% of people who were newly diagnosed with HIV in England were diagnosed late. This means they were diagnosed with HIV once their immune system had already been weakened.

Late diagnoses are more common in heterosexual men and women compared to gay and bisexual men. Older people are also more likely to be diagnosed late than younger people.

What is the future of HIV in the UK?

The number of people being diagnosed with HIV in the UK has been decreasing since 2005. The UK government currently has a goal of no new transmissions of HIV by 2030.

The plan for meeting this target involves:

• increasing testing
• increasing access to prevention methods such as PrEP
• making sure as many people with HIV as possible have access to treatment, which prevents HIV transmission.

By taking anti-HIV treatment, people can live long and healthy lives. This will also mean that in the UK, the future will include a lot of people living with well-controlled HIV.
