Streptococci cause several diseases. Group A hemolytic streptococcal infections include acute pharyngitis, impetigo, erysipelas, scarlet fever, rheumatic fever, acute nephritis, and puerperal fever, the last of which, called childbed fever at the time, was a common cause of death in the immediate postnatal period in the days before antisepsis. This still occurs in some rural regions of low-income countries where childbirth antisepsis is inadequate. All these diseases are preventable by attention to asepsis, and most respond to antibiotics.
