The infection is generally transmitted by direct contact with the mucus or sores of someone else with strep.
Common symptoms include sore throat, fever, and swollen lymph nodes in the neck. Rarely, complications can involve the heart or kidneys.
Treatment is important to reduce complications. Oral antibiotics like penicillin, amoxicillin, cephalexin, or azithromycin are commonly used. Other medicines such as acetaminophen or ibuprofen can help with pain and fever.
