Strep Throat

Strep throat is a bacterial infection that causes inflammation and pain in the throat. It is commonly seen in children and can be spread through close contact. Symptoms may include a sore throat and difficulty swallowing, but not everyone experiences the same signs.

  • What exactly is strep throat and how does it spread?
    MedlinePlusMay 2026

    Strep throat is a sore, red throat caused by group A streptococcus bacteria, and your tonsils may swell with white spots on them. It spreads through respiratory droplets when an infected person coughs or sneezes, or by sharing drinks and utensils.

  • Can I get strep throat more than once?
    MedlinePlusMay 2026

    Yes, you can get strep throat more than once because catching it once doesn't give you permanent immunity to the bacteria.

  • How long will my sore throat last without treatment?
    MedlinePlusMay 2026

    Without treatment, strep throat symptoms typically last about a week, though the infection can linger longer and increase your risk of serious complications.

  • Why do some people get scarlet fever from strep throat?
    MedlinePlusMay 2026

    Scarlet fever is an illness that sometimes follows strep throat in some people and causes a red rash on the body, but doctors don't fully understand why it develops in some patients and not others.

  • Is there anything I can do to prevent getting strep throat?
    MedlinePlusMay 2026

    You can reduce your risk by washing your hands often, avoiding close contact with sick people, and not sharing drinks or eating utensils with others.
