Alternative Names:

Pharyngitis - streptococcal; Streptococcal pharyngitis

Prevention:

Most people with strep are contagious until they have been on antibiotics 24-48 hours. Thus, they should stay home from school, daycare, or work until they have been on antibiotics for at least a day.

Get a new toothbrush after you are no longer contagious, but before finishing the antibiotics. Otherwise the bacteria can live in the toothbrush and re-infect when the antibiotics are done. Also, keep your family's toothbrushes and utensils separate, unless they have been washed.

If repeated cases of strep still occur in a family, you might check to see if someone is a strep carrier. Carriers have strep in their throats, but the bacteria do not make them sick. Sometimes, treating them can prevent others from getting strep throat.
