Epidemiological Triangle of HIV

The epidemiological triangle of any disease system is broken into three subsections, all interlinked with one another: host (individual in a given population), environment, and agent. All three of these attribute to an equally important 'detective' approach to a disease. Particularly with HIV, the host is most commonly isolated (but not limited to) homosexual black males. However, any party could be infected by HIV; it is not gender, race, or age-exclusive. The agent by which HIV is carried is a virus of varying subtypes that travels via seminal fluids, vaginal fluids, rectal fluids, and blood. The environment that the virus thrives in is universal - but particularly areas with a close concentration of unprotected sexual activity and general risky behaviors.
