the seasonal variations of polio-virus excretor rates in Chinese children under five years of age. These surveys showed that polio-virus and other entero-viruses are distributed widely in the normal child population, the excretor rate being highest in the summer and declining gradually towards the end of the year. Types 1 and 3 polio-virus are the prevalent types and there is only a rough correlation between the excretor rate and the notification rate with a mean rate of 1,200 to 1. From clinical cases and their contacts a total of 1,060 specimens were examined amongst which 181 were positive for type I and 22 for type 3; no type 2 viruses were isolated.
388. Amongst other entero-viruses, Coxsackie viruses A9 and B3 were isolated as were ECHO types 2, 5, 6 and 8.
389. From time to time throat washings from suspected cases of influenza are investigated to ascertain the prevalent strain. There were two positive isolates obtained during the year which were antigenically kdentical with the A2/57 (A/Asian/57) strain supplied by World Health Organization.
