Communicable 1-2 days before rash appears, until all lesions have crusted, usually 7 days. May return to school when all scabs are crusted.

CROUP
Incubation: 2-9 days, depending on causative agent. Acute respiratory infection involving epiglottis, larynx, trachea and bronchi. May cause respiratory distress ranging from mild to severe. Cough has "barking" or "brassy" harsh quality. May notice a high pitched sound on inhalation. Communicable during duration of disease. Exclude when fever present or if child is uncomfortable.
