Opportunistic infections


October 9th, 2011

In the absence of effective treatment against HIV, the immune system of the infected person weakens and the body can no longer defend itself properly. Even microbes that usually do not cause any problems and are quickly eliminated become dangerous intruders that can create real diseases. These are called opportunistic infections because they take advantage of a weak immune system. These opportunistic infections, and not the AIDS virus itself, are what often cause the death of those not treated with antiretrovirals.
