What are the symptoms of HIV and AIDS?

It is not possible to reliably diagnose HIV infection or AIDS based on symptoms alone. HIV symptoms are very similar to the symptoms of other illnesses. So the only way to know for sure whether a person is infected with HIV is for them to have an HIV test.

People living with HIV may feel and look completely well but their immune systems may nevertheless be damaged. It is important to remember that once someone is infected with HIV they can pass the virus on immediately, even if they feel healthy.

HIV is the virus that causes AIDS. If a person infected with HIV does not take effective antiretroviral treatment, over time HIV will weaken their immune system, which will make them much more vulnerable to opportunistic infections.
