COMMUNITY outbreaks of poliomyelitis have been reported frequently in the litera¬ ture, particularly during the last 30 years.Yet new epidemiological patterns, as observed in the outbreak of 113 paralytic cases of poliomyelitis in Seattle-King County, Wash., in 1959, recall the wisdom of Benjamin Rush (1): "Above all, record the epidemics of every season.Such records, if published, will be useful to foreign¬ ers and a treasure to posterity."
