If you catch strep throat, you will usually start feeling sick two to five days after you are exposed to the bacteria that causes the infection. There are several symptoms of strep throat, but the most common is a very sore throat.
Other symptoms of strep throat are:
- Difficulty swallowing or pain when swallowing (which might also be felt in the ear on the same side)
- Fever (101° F or higher)
- Red, swollen tonsils that may have white patches or streaks of pus on them
- Tiny red spots on the roof of the mouth (called petechiae)
- Swollen lymph nodes in the front of the neck
- Chills
- Fatigue
- Headaches
- Loss of appetite
- Abdominal pain
How Long Is the Contagious Period of Strep Throat?
Strep throat is highly contagious through airborne particles, touching a contaminated surface, or sharing personal items like food utensils. You’ll feel sick about two to five days after exposure. After 24 to 48 hours of taking antibiotics, the infection should no longer be contagious. Good hygiene practices, such as hand washing, will help with strep throat prevention.
