Can an infection cause low levels of white blood cells?

ANSWER

Viruses can affect your bone marrow and cause low white blood cell levels for a while. Severe infections, like blood infections, can lead to your body using up white blood cells faster than it can make them. HIV kills a specific kind of white blood cell.
