Early symptomatic HIV infection is characterized by signs and symptoms typical of HIV infection that are not AIDS-defining. These symptoms are usually not present in acute or asymptomatic HIV infection . The onset of symptoms signals the transition from HIV infection to HIV disease . Risk factors for HIV infection are sexual contact with an infected sexual partner that includes exchange of semen or vaginal secretions, intravenous drug use, receipt of blood transfusion or blood components, or being born to an HIV-positive mother. Prevention Safer sex behaviors may reduce the risk of acquiring the infection.
Abstinence is the only sure way to prevent sexual transmission of the virus.
If IV drugs are used, do not share needles or syringes. People with AIDS or who have had positive antibody tests may pass the disease on to others and should not donate blood, plasma, body organs, or sperm. They should not exchange body fluids during sexual activity. This time varies greatly from person to person and can depend on many factors. The only way to determine for sure whether you are infected is to be tested for HIV infection.
