How long are you contagious with strep after you have started taking amoxicillin?

Generally 24 hours: Once on the antibiotic for 24 hours is typically when schools allow students to go back to class, but i would also recommend reducing your exposure to others until the fever is gone and you start to feel better.

Depends: The general rule is 24 hours for public exposure. However, you might want to avoid deep smooching with your spouse & family members for a few days to be sure
