Initial stage of HIV infection
Most of the serious scientists believe AIDS is caused by HIV virus. HIV infection is very insidious, because the virus penetration into the human body and reproduction in most cases does not cause any specific AIDS symptoms at the beginning. HIV test is the only reliable way to determine HIV status. HIV virus affects the immune system and the central nervous system. That’s why at much later stage the infected person suffers from diverse symptoms connected with poor functioning of these systems.
So the initial HIV/ AIDS symptoms are implicit. For example, in a few weeks after the infication the body temperature may increase slightly (99.5 – 100.4°F) accompanied by enlarged lymph nodes, sore throat, red spots on the skin, sometimes diarrhea.
These symptoms of AIDS are often neglected and thought they are caused by slight flu or intestinal disorder. Even not each HIV infected person has these symptoms; in those who do have the AIDS symptoms and signs they last for a short time. But if the symptoms are really caused by HIV infection their disappearance means the infection is propagating in the body.
