*Source: Control of Communicable Diseases Manual 17th Edition [8]. +The maximum state-specific median reporting delay for this disease and date type is from a state that reported 19 cases having event years 1919 or 1920. Excluding these cases as data entry errors, the maximum state-specific median reporting delay is 78 days. aState-specific median reporting range (minimum, maximum) in days b% of cases reported within 1 and 2 incubation periods, respectively
