The ones who might already have an infection or have a low immune level.
An opportunistic infection (OI) is an infection that occurs only when the host's defense systems (ie, the immune system) are weakened. The common characteristic of all agents that cause opportunistic infections is that they rarely affect individuals with healthy immune systems. For example, the disease AIDS (acquired immunodeficiency syndrome) is a classic cause of immune system depression and is associated with many opportunistic infections, including toxoplasmosis, pneumocystis pneumonia (PCP), and others.
