Moore HE14: Critical Issues in Personal Health Infectious Disease Extra Credit Paper April 28‚ 2012 Scarlet Fever Definition Scarlet fever (sometimes referred to as scarlatina) is an infectious disease characterized by fever‚ sore throat (pharyngitis)‚ and a characteristic rash. Scarlet fever is predominantly a childhood disease occurring in children 2-10 years of age‚ though it can less commonly occur in older children and adults. The incidence and mortality rates associated with this once

infection patients include antibodies to the envelope glycoprotein gB surrounding the cytomegalovirus. CMV presents very similarly to EBV but there are a few differences‚ CMV often has no accompanying posterior cervical adenopathy‚ nonexudative pharyngitis is minimal‚ splenomegaly is much less common‚ and CMV tends to persist for a longer period of time then EBV. CMV can be diagnosed with findings of viral inclusion bodies “owl’s eye” found on histocytological examination‚ though this is considered

used similar methods to classify S. haemolyticus into groups according to antigens composed of carbohydrate. She also demonstrated that one of these groups‚ group A streptococci (S. pyogenes)‚ was specific to humans and human disease‚ including pharyngitis ("strep throat")‚ scarlet fever‚ rheumatic fever‚ nephritis and impetigo. Group B streptococci were subsequently shown to be associated with neonatal disease. Dr. Lancefield further elaborated on the extensive variety of the group A streptococci
