Re: Tonsillitis, still contagious?
My rule of thumb is to allow plenty of time for any contagious illness to pass before chancing spreading it to anyone else. If any symptoms are present, I would not get too close to anyone, and practice extra safe hygiene with hand washing, not sharing utensils, towels, etc., and cover all coughs and sneezes.
You never know now illness can affect others, and it is better safe than sorry. Be well!
