Strep throat
Strep throat is a bacterial infection caused by group A streptococcus. It typically starts suddenly: severe sore throat, pain when swallowing, fever, and swollen tonsils — sometimes with white patches — usually without a cough. It is most common in children and teens, but adults get it too, especially parents and teachers. Unlike most sore throats, strep requires antibiotics.
Why testing matters
Strep cannot be confirmed by looking at the throat — even experienced clinicians cannot reliably distinguish it from a viral infection by sight. A rapid strep test or throat culture gives the answer in minutes. This matters because most sore throats are viral, and antibiotics do nothing against viruses; taking them unnecessarily only builds resistance.
How it is treated
Confirmed strep is treated with a course of antibiotics, which shortens the illness, cuts contagiousness quickly, and — most importantly — prevents rare but serious complications like rheumatic fever, which can damage the heart. Completing the full course matters even when symptoms disappear after two or three days: stopping early lets the bacteria persist.
Preventing spread
Strep spreads through respiratory droplets, so cover coughs, wash hands frequently, and avoid sharing cups or utensils while sick. After about 24 hours on antibiotics, most people are no longer contagious.

Frequently asked questions
Strep tends to come on suddenly, with significant pain when swallowing, fever, and swollen tonsils — and typically no cough or runny nose. Sore throats that come with cough, congestion, and hoarseness are usually viral. Only a test confirms the difference.
No — most sore throats are viral and resolve on their own with rest and fluids. Antibiotics are reserved for confirmed bacterial infections like strep, which is exactly why testing before treating is the standard of care.
Most cases eventually resolve, but untreated strep carries a small risk of serious complications, including rheumatic fever — which can permanently damage heart valves — and kidney inflammation. Antibiotics make these complications preventable, which is why confirmed strep is always treated.
Without treatment, you can spread strep for two to three weeks even as symptoms fade. With antibiotics, contagiousness drops sharply — most people can return to work or school after 24 hours of treatment, once the fever is gone.
Symptoms usually improve within days, but the bacteria are not yet fully eliminated. Stopping early allows the infection to persist or return and contributes to antibiotic resistance. The full course is what prevents complications.
