Detailed explanation-1: -When germs take advantage of your weakened immune system, they are called opportunistic infections (OI). OIs that other people might fight off easily or never even get could occur more often and be more severe if you have HIV. Getting one or more of these infections could mean that your HIV has advanced to AIDS.
Detailed explanation-2: -Tuberculosis (TB). TB is a common opportunistic infection associated with HIV . Worldwide, TB is a leading cause of death among people with AIDS .
Detailed explanation-3: -Opportunistic infections (OIs) capitalize on weakened immune systems. In general, complications of HIV don’t occur if the body’s CD4 count is higher than 500 cells per cubic millimeter. Most life-threatening complications occur when the CD4 count drops below 200 cells per cubic millimeter.
Detailed explanation-4: -What Causes Opportunistic Infections? OIs are caused by a variety of germs (viruses, bacteria, fungi, and parasites). These germs spread in different ways, such as in the air, in body fluids, or in contaminated food or water. They can cause health problems when a person’s immune system is weakened by HIV disease.
