Integrity Urgent Care First Aid Handbook – Strep Throat

Strep throat is an infection of the throat and tonsils caused by bacteria called Streptococcus pyrogenes that live in the nose and the throat. It is more likely to develop in people who have spent time in close contact with someone who has strep throat or a crowded place. It is most common in children and teens, but adults can also get it as well.
