RT Journal T1 Zur epidemiologie der kinderlähmung: Eine statistische analyse JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1939 FD October 28 VO 113 IS 18 SP 1666 OP 1666 DO 10.1001/jama.1939.02800430058035 UL http://dx.doi.org/10.1001/jama.1939.02800430058035 AB This book contains an analysis of one epidemic of poliomyelitis which occurred during the years 1935-1937. They had 266 cases of paralysis, sixty-two abortive cases and 129 suspects. No epidemics had occurred in this area previous to 1935. Jönsson considers that the maximum of dissemination of poliomyelitis lies between the maximum of the intestinal diseases typhoid and dysentery on the one hand and contact diseases such as diphtheria and scarlet fever on the other hand. It was found that the disease did not follow the waterways but was most common in areas with the most crowded population.
