Secondary infections

Definition

A secondary infection is an infection that occurs during or after treatment of another pre-existing infection. It may result from the treatment itself or from changes in the immune system.

For example, a vaginal yeast infection that occurs after antibiotic treatment of a bacterial infection is a secondary infection. Bacterial pneumonia after a viral upper respiratory infection is another example.
