Strep A is a common type of bacteria. Most strep A infections are mild and easily treated, but some are more serious.

Symptoms of a strep A infection

Common symptoms of strep A include:

• flu-like symptoms, such as a high temperature, swollen glands or an aching body
• sore throat (strep throat or tonsillitis)
• a rash that feels rough, like sandpaper (scarlet fever)
• scabs and sores (impetigo)
• pain and swelling (cellulitis)
• severe muscle aches
• nausea and vomiting

Most strep A infections are not serious and can be treated with antibiotics.

But rarely, the infection can cause serious problems. This is called invasive group A strep (iGAS).
