“There is stage 1-Within 2 to 4 weeks after infection with HIV, about two-thirds of people will have a flu-like illness. This is the body’s natural response to HIV infection.  These flu-like symptoms can last anywhere from a few days to several weeks. But some people do not have any symptoms at all during this early stage of HIV.  In stage 2, the virus still multiplies, but at very low levels. People in this stage may not feel sick or have any symptoms. This stage is also called chronic HIV infection.  If you have HIV and you are not on HIV treatment, eventually the virus will weaken your body’s immune system and you will progress to AIDS (acquired immunodeficiency syndrome). This is the late stage of HIV infection.”.
