It could also be classed as an opportunistic, viral disease.

Though the drugs cost the the department about $3 million annually, he added, inmates are subjected to fewer opportunistic diseases.

A decreased CD4 count, in combination with higher numbers on a viral load test, indicates an increased risk of getting sick from opportunistic diseases.

Tuberculosis is an opportunistic disease.

This helps keep a person's immune system healthy longer, which may slow the rate at which opportunistic diseases (such as pneumonia) develop.

You die of opportunistic diseases.
