Chronic infection is characterized by the continued presence of infectious virus following the primary infection and may include chronic or recurrent disease. Slow infection is characterized by a prolonged incubation period followed by progressive disease.

Do viruses lay dormant?

Viruses can lay dormant, also referred to as “viral latency” which means a virus has the ability to remain inactive for a period of time within its host. Since the virus has found a home within its cell, it only needs to be triggered to become active.
