Scarlet fever is an infection caused by which bacteria?

Scarlet fever is caused by the bacteria Streptococcus, specifically Streptococcus pyogenes, which is also known as group A Streptococcus. This bacterium produces a toxin that leads to the characteristic rash associated with scarlet fever, as well as symptoms like a sore throat and fever. The bacteria spreads through respiratory droplets or direct contact with an infected person's skin lesions. The correct identification of Streptococcus pyogenes is crucial for effective treatment and prevention of complications associated with the infection.
