The complexity of the HIV infection lies in the fact that there is no specific symptom linked to it; thus detection becomes difficult. The only way to find out you have the disease is to test for HIV antibodies to be able to identify the disease. Some of the most common symptoms linked to it are rapid weight loss, unexplained fevers, night sweating, sudden loss of weight, loss of appetite, and swelling of the lymph nodes and sometimes even rashes though they not conclusively prove that one suffers from HIV. The main point to remember is that the infection can cause different symptoms in different people and that can confuse patients. The first sign of infection is an unexplained fever which comes 2-4 weeks after exposure. After that even if the person is infected, the patient continues normally without any symptoms. Yet the virus is active in the body destroying healthy cells. Eventually one day, the immune system is so destroyed that the patient falls in to full blown AIDS
