The first symptoms and symptoms of HIV contamination are flu-like signs and symptoms which might be visible inside 2 to four weeks upon getting inflamed. This is called number one or acute HIV contamination. Some humans do now no longer have any signs and symptoms for the duration of this phase. It is accompanied through a latent degree for the duration of which the virus multiplies and commonly there aren't anyt any detectable symptoms and symptoms and signs and symptoms. Gradually the virus weakens the immune machine and progresses to AIDS.
    The maximum not unusualplace motive of HIV is sexual touch with the inflamed individual. A individual also can get inflamed through blood transfusion, sharing inflamed needles and syringes infected with inflamed blood. Pregnant ladies inflamed with HIV can transmit the virus to the fetus via shared circulation.
    Although the therapy for the ailment remains below research, a few medicinal drugs at sure tiers can lengthen the existence of HIV-effective sufferers. These medicinal drugs encompass protease inhibitors, fusion inhibitors, multidrug combinations, HIV-effective and opposite transcriptase inhibitors.
