the.com/recurrence
Often used when an illness returns after a period of remission.
means The act or fact of something happening again after it already happened once — a repeat appearance, often unwelcome.
from From Latin recurrere — re- 'again, back' plus currere 'to run.' So literally 'to run back,' the way a thought, a fever, or a bad habit circles back to where it started. Currere is the same root that gives us current, course, and courier — all things that run. Recurrence just means the running came back around.
