集団赤痢の発生原因と接触感染

抄録

There has been many reports of outbreak of bacterial dysentery registering the contact infection as their cause.
Of 2398 outbreaks registered in Japan during 1956 and 1962, 1330 (55.5%) were notified as contact infection or unknown cause.
However reports which detected the infectious routes and the accurate date were rather few.
It is conceivable that cases of unknown cause were innocently registered as the contact infection.
The author performed the survey on an outbreak of bacterial dysentery which occurred in the nursery school in Nagoya city in 1963.
In this study the cases were presented in which the contact routes (nursery school childrentheir family-primary school children-their family) and the accurate date were successfully detected.
