Most people infected with HIV experience a short, flu-like illness that occurs 2-6 weeks after infection. After this, HIV may not cause any symptoms for several years.
It's estimated up to 80% of people who are infected with HIV experience this flu-like illness.

Other symptoms can include:
The symptoms usually last 1-2 weeks, but can be longer. They're a sign that your immune system is putting up a fight against the virus.

If you have several of these symptoms and think you've been at risk of HIV infection within the past few weeks, you should get an HIV test.

Earlier diagnosis and treatment of HIV can prevent these problems.
