What is strep throat and what causes strep throat?

Strep throat is a bacterial infection of the soft palate and tonsillar region. Microbiologists identify the member of the Streptococcus bacterial family that causes strep throat as "GAS" (Group A, beta hemolytic, Streptococcus pyogenes). Strep throat is most common in young children and adolescents, but it is not unusual in toddlers and adults. It is highly contagious and it is present most commonly in the community during the winter months. Interestingly, the symptoms and physical signs may vary depending upon the age of the infected patient.
