The most common types of streptococcus that affect children are Group A Streptococcus (GAS) and Group B Streptococcus (GBS). Group A Streptococcus, also known as Streptococcus pyogenes, is typically responsible for conditions like strep throat, scarlet fever, and impetigo. Group B Streptococcus is more commonly associated with neonatal infections.
