This is within 2-4 weeks after being infected by the HIV. The most common symptoms of this stage are flu like symptoms such as fever, sore throat, body rash, lethargy, headache, and muscle and joint pains. Such symptoms may last a few days or a few weeks. It is important to remember that some people may not experience any symptoms at all.
Clinical latency stage
During this stage which may take up to 10 years the virus is active and progressively damaging the immune system, however no particular symptoms are observed.
Progression to AIDS stage
If left untreated during the early or clinical latency stage, the disease can progress into the AIDS stage which is the final stage of infection. At this stage symptoms such as rapid weight loss, pneumonia, chronic diarrhoea (lasting more than 1 week), Skin problem, extreme and unexplained tiredness, recurring fever and night sweats, recurrent infections, and sore of mouth, genitals, and anus may be experienced.

This is a month long treatment with serious side effects and is not guaranteed to work. PEP is available in sexual sex or genitourinary medicine clinics, as well as hospitals.
HIV is treated with antiretroviral (ARV) medicines. A combination of ARVs is usually provided to prevent development of resistance by HIV. To increase compliance to treatment some ARVs are made into one pill.
To prevent HIV infection it is important to reduce the risk of exposure. This is achieved through:
