Common questions from parents
- How long is my kid contagious?
- It depends on the illness. Most respiratory bugs (colds, flu, RSV) are contagious a day or two before symptoms and for several days after; strep throat is contagious until they've been on antibiotics for at least 12 to 24 hours. Individual guides below have the specifics.
- When can they go back to school or daycare?
- The standard rule is 24 hours fever-free without medication, no vomiting or diarrhea for at least 24 hours, and, for strep or pink eye, at least a day on treatment. Check your school's policy too, some are stricter.
- How do I know if it's a virus or something like strep?
- Sore throat with fever and no cough is more suspicious for strep, sore throat with a runny nose and cough is usually viral. A quick strep test at the pediatrician is the only way to know for sure.
