For example: the herpes virus that causes cold sores stays in nerves in the head, and are released from periods of high stress. Ebola virus stays dormant in the eye and sperm of men even after the person has recovered from the disease.
The immune system doesn't have to clear a pathogen from the body, just has to stop it from causing sickness. But in many cases viruses are believed to stay with you for life, though sometimes they stop showing up on blood tests and symptoms disappear. Bacteria, fungal, and parasitic pathogens can be cleared permanently from the body.
