HIV-Related Behaviors

HIV causes AIDS and interferes with the body's ability to fight infections. The virus is often transmitted through contact with infected blood, semen or vaginal fluids.Within a couple of weeks of HIV infection, flu-like symptoms like fever, pharyngitis and fatigue can occur. Then the disease is typically asymptomatic until it progresses to AIDS. AIDS symptoms include weight loss, fever or night sweats, fatigue and recurrent infections.No cure exists for AIDS, but strict adherence to antiretroviral regimens (ARVs) can dramatically slow the disease's progress also as prevent secondary infections and complications.The development of a vaccine against HIV may be a global health priority and an incredible scientific challenge that has been hampered by the extraordinary genetic diversity of HIV and therefore the immune evasive properties of the HIV envelope glycoprotein to which neutralizing antibodies target. Despite the event of antiretroviral therapy which will extend the lifetime of infected individuals, these drugs aren't widely available within the underdeveloped world and, thus, a therapeutic vaccine would be of great benefit.
