Fact sheet: Streptococcal sore throat is a bacterial infection of the throat and tonsils caused by Streptococcus pyogenes.
Streptococcal sore throat is a bacterial infection of the throat and tonsils caused by Streptococcus pyogenes.
Streptococci are spread when an infected person talks, coughs or sneezes small droplets containing infectious agents into the air. The droplets may be breathed in by those nearby. The droplets may contaminate hands or objects such as drinking cups or eating utensils. Sometimes spread occurs by eating contaminated food by direct contact with infected wounds or skin sores.
Complications of this infection may include:
Diagnosis is made by taking a throat swab and sending this to the laboratory for testing. A sore throat may also be caused by a viral infection and testing a throat swab is the only way to tell the difference between the two conditions.
(time between becoming infected and developing symptoms)
1 to 3 days.
(time during which an infected person can infect others)
Untreated people remain infectious for 2 to 3 weeks after becoming ill. Treated people are infectious for about 24 hours after appropriate antibiotic treatment begins.
Effective antibiotic treatment is available. To prevent potential complications, the full course of antibiotics should be completed.
