Human Infection with Pasteurella septica

A SMALLPOX EPIDEMIC MEDICBALOURNAL 725 contacts isolated. (4) No draft:ng of naval personnel, other than direct contacts, was stopped provided they had been vaccinated and showed good scars.Course of the Epidemic By March 2 (thirty-six days after the first case had occurred in the Navy) there had been six naval cases; of these, three showed no scars indicative of previous successful vaccination, and a fourth had only a very small scar.It was decided, there- fore, that the scheme was not working satisfactorily because all personnel were still not vaccinated, and that more drastic steps must be taken to obtain 100°o immunity.Consequently, all leave to and from the base was stopped, and liberty-men were not allowed ashore unless in possession of documentary evidence of vaccination within the past tWo years.These restrictions, especially the formner, had the desired effect of making all naval personnel, and particularly officers, smallpox-conscious and vaccination-minded.From this date onwards there was a noticeable increase in the numbers pre- senting themselves for vaccination, and the epidemic in the Navy rapidly subsided.It was possible to raise the ban on leave by March 12.
