What causes strep throat?

Strep throat is caused by Group A Streptococcus bacteria, which invade the tissues within the throat and cause a localized infection of the throat (pharyngitis) and tonsils (tonsillitis). the bacteria are passed from one person to another via droplets from coughing and sneezing, or by sharing food or drinks. For this reason, strep throat often spreads among members of the same household.
