HIV-Infected People Become Infectious Almost Immediately
Now researchers at the University of North Carolina-Chapel Hill suggest that a newly infected individual can transmit HIV to someone else in just five days. Their study examined five people newly infected through unprotected sexual intercourse, finding them to be fully infectious to others by five to 13 days after infection.
Indeed, previous studies had shown that this early period of infectiousness will be one of the most dangerous periods: The virus is multiplying unchecked in the new host's body because his/her own body has not yet begun to make an antibody immune response to try to control it. With these extreme virus levels, the individual is exceptionally infectious; within a few weeks, after antibody response has kicked in, viral quantities - and infectiousness - will fall to more "normal" levels.
This underscores the need to quickly identify people newly infected with HIV, so they can refrain from exposing others, as well as begin to care for themselves. Austin is one of the easiest places anywhere to get an HIV test. Just call 708-3500 and they'll provide all kinds of options. Anyone who has engaged in risky behavior should seriously give it a shot.
