To the Editor:—
The current comment on immunization against infectious diseases in large cities (The Journal, September 18) states that immunizations against typhoid were "negligible in frequency as compared with those against diphtheria and smallpox." It appears to be little known that in the spring of 1942 about 90 per cent of the population of the Territory of Hawaii received typhoid-paratyphoid inoculations. This program was instituted by the department surgeon (Brig. Gen. Edgar King) because there was no line of separation between military and civilian health problems in that territory. The wisdom of this move was dramatically revealed by the occurrence of an epidemic of typhoid in Honolulu (described in the Hawaii Medical Journal) shortly after the inoculation program was instituted (and long before it was completed). The incidence of typhoid in Hawaii during the postinoculation years should serve as the basis of an interesting study.
