which body system does strep throat affect
A Honor Society of Nursing (STTI) answered. Once the streptococcus bacteria group A enters your nose or mouth, the germs will attack the tissues of your throat. Certain areas of the throat may even swell, like your tonsils, which is a sign that your immune system is trying to fight off infection. As the bacteria grow, the pain in your throat will develop and you may have a fever that signals your body is still fighting.
