Relapsing
“Relapsing” refers to the recurrence or return of a disease or condition after a period of improvement or remission. It is often used in medical contexts to describe illnesses that follow a pattern of recurring episodes or symptoms after periods of stability.
For example:
Relapsing-Remitting Multiple Sclerosis (RRMS): A form of multiple sclerosis characterized by episodes of new or worsening symptoms (relapses), followed by periods of partial or complete recovery (remissions).
Relapsing Fever: A condition marked by recurring episodes of fever, typically caused by bacteria from the Borrelia species.
