How Long Is Strep Throat Contagious?

Strep Throat Basics


Strep throat is caused by the bacteria streptococcus pyogenes. It is considered GAS, which stands for Group A Streptococcus infection, and you can be contagious for a 2- to 5-day period before you even start to experience symptoms. During this time, you will probably unwittingly share your germs with someone else. Once you start to have symptoms and suspect you may have strep throat, you are contagious and should start taking precautions not to infect those around you.
