Symptoms

If you have strep throat infection, you will have a red and painful sore throat and may have white patches on your tonsils. You also may have swollen lymph nodes in your neck, run a fever, and have a headache. Nausea, vomiting, and abdominal pain can occur but are more common in children than in adults.

You can get sick within 3 days after being exposed to the germ. Once infected, you can pass the infection to others for up to 2 to 3 weeks even if you don’t have symptoms. After 24 hours of taking antibiotics, you will no longer spread the bacteria to others.
