In the autumn of 1922, we had an opportunity to observe an epidemic of a peculiar, acute disease which occurred in a large preparatory school for boys. The disease evidently was introduced by a lad returning from his summer vacation. It began in one of the houses, rapidly ran through the susceptible boys in that house and, in the meantime, extended to the rest of the school. The student body consists of about 500 boys, ranging in age from 13 to 18, and it was notable that chiefly the younger boys were affected, whereas most of the older ones escaped entirely; among sixty masters, nurses and physicians there was but one patient. The time covered by the epidemic was about nine weeks, from the latter part of September to the third week in November, 1922. From that time until the time of writing, not a single case has been observed |
