The incidence of poliomyelitis in Cleveland peaked in August, September, and October, without the noticeable spring increase observed in broader United States data.
Highlights the seasonal incidence patterns of poliomyelitis in the United States, specifically in Cleveland.
Elsewhere1we plotted the incidence curve of infantile paralysis for Cleveland and vicinity, a curve which had its peak in the months of August, September and October. Aycock and Eaton2have called attention to the biseasonal prevalence of the disease in the United States, and their figures show a very evident spring hump in the morbidity rate. Such a spring incidence might pave the way for a subsequent seasonal epidemic. We have not experienced a noticeable increase of cases in our community in the spring. It is probable, however, that if many districts such as ours were lumped together this increase of cases in the spring would become more obvious. Our local hospital and the board of health reports are slightly at variance with each other, the former with few reported cases in the winter and the latter with a greater number. Many patients are admitted to the
