Frequently Asked Questions

How long is the incubation period for strep?

After you’ve come in contact with group A Streptococcus, the bacteria that cause strep throat, it usually takes two to five days before you feel ill. You may not even know you were exposed to the illness. That’s because people who are infected with group A strep may not have symptoms. You are most contagious when you have a fever over 100.4 but can be contagious to others for 48-hours before the symptoms begin.

 If you have strep throat, you can spread it to others until you have been taking antibiotic treatment for one to three days. Children with strep throat shouldn’t return to school or day care until they no longer have a fever and have been taking antibiotic treatment for 24 hours.
