The outbreaks of diphtheria at the Infirmary and the Orphanage of Mercy were responsible
for much of the increase in the number of specimens under that head, 340 "swabs" (66 positive
and 274 negative) being received from the former institution and 43 (8 positive and 35 negative)
from the latter. The systematic swabbing of all contacts is the only efficient method of stamping
out the disease.
The Medical Officer of Health took 31 swabs (2 positive only) at the Town Hall, most of
them from persons connected with the milk trade. Pressure of other work prevented any
specimens of hairs being examined during the past year.
The total proportion of positive results was rather lower last year than in 1912, 191 per
cent., as compared with 19 6. In 1911 the proportion was 322, and in 1910, 24.5. In the case
of diphtheria only was the proportion higher than in 1912. (See below.)
