Streptococcus pyogenes Most cases of<unk>  are due to Streptococcus pyogenes, also known as group A β-hemolytic streptococci, less commonly by group C or G streptococci and rarely due to Staphylococcus aureus. Newborns may contract<unk>  due to Streptococcus agalactiae, also known as group B streptococcus or GBS. The infecting bacteria can enter the skin through minor trauma, human, insect or animal bites, surgical incisions, ulcers, burns and abrasions. There may be underlying eczema or athlete's foot (tinea pedis), and it can originate from streptococci bacteria in the subject's own nasal passages or ear. The rash is due to an exotoxin, not the Streptococcus bacteria, and is found in areas where no symptoms are present; e.g., the infection may be in the nasopharynx, but the rash is found usually on the epidermis and superficial lymphatics.
