Apology Letter For Spreading an Illness
Dear {Recipient},
My apologies for spreading the {flu/mumps/etc.} at our {workplace/school/etc.}. I thought I had already fully recoveredâI was feeling good and really eager to get back to {work/class/etc.} after spending {number of} {days/weeks} {at home/in bed}. I should have waited a couple more days before returning.
I'm so sorry you got sick because of me. I hope you get well soon!
Sincerely,
{Your Name}
