SMALLPOX VACCINATION
Seven thousand six hunched and forty-four persons received
primary vaccination and seven thousand five hundied and forty-six
re-vaccination.
The considerable increase in the number of vaccinations against
smallpox was due to the widespread desire for vaccination as a result
of the importation into the country of smallpox, as referred to
elsewhere in this report.
FOOD POISONING
Of the seven cases of food poisoning which were notified during
the year, all were single cases due to Salmonella Organisms.
SONNE DYSENTERY
The incidence of mild dysentery due to Shigella Sonnei showed
a considerable increase on last year's figure, with seventy-seven cases
as against four for the previous year, but this is an infection which
is likely to vary considerably in incidence, especially as its spread is
so easily encouraged by careless personal hygiene.
