title: Updates: Routine screening for antibodies to HIV-1, civilian applicants for U.S. military service and U.S. Armed Forces, active and reserve components.
abstract: During routine testing of civilian applicants for U.S. military service, the overall seroprevalence of antibodies to HIV-1 was lower in 2010 than in any year since 1990. Among members of the active components of the U.S. Army and Air Force, HIV-1 seroprevalences were higher in 2008-2010 than in recent prior years. Among members of the active components of the U.S. Navy and Marine Corps, the Marine Corps Reserve, and the Army National Guard, HIV-1 seroprevalences have slightly declined or remained relatively stable for at least ten years. In the reserve components of most of the service branches, it is difficult to discern long-term trends because of instability of seroprevalences observed in the relatively small numbers of reserve component members tested each year.
