Opportunistic infections are infections that occur more often in those with a weaker immune system, including those with HIV. Although opportunistic infections aren’t as common now due to the advancement in treatment for HIV and AIDS, they may occur in those who have tested positive for HIV and haven’t received proper treatment or haven’t started treatment.

Causes of opportunistic infections


Opportunistic infections are caused by a variety of bacteria, viruses, parasites and fungi. These germs can spread in a variety of ways and can cause health problems in those with HIV - the reasoning for this being simple; HIV weakens the immune system and makes it difficult for the body to fight off the infection [2].
