In all infected homes the disinfection was performed by the
Sanitary Authority. A visit was paid to every house, and it was
ascertained that cases of infectious illness occurred in 4 houses where
there were "grave" insanitary conditions. In 19 houses less
serious insanitary conditions were found.
In arriving at these conclusions, I have considered whether
any sanitary defect was of a nature which is generally believed to
predispose to the particular disease in question.
Thus, apart from the measures that have been taken to prevent
the spread of infectious illness, the notification of such illness
was the means during the year of bringing about a sanitary inspection
of some 500 premises.
Table VII. shows the cases of Infectious Diseases notified
during each month of the year 1916.
The Infectious Sickness Rate of the Borough, excluding the
notifications from Consumption, Cerebro-spinal Meningitis, Acute
Polio-Myelitis, Ophthalmia and Measles, so as to make the rate
comparable with that of former years, was 4.4 to each 1,000 of the
population, as against 70 for the preceding year. The rate in
the Northern Division was 2.8; while that in the Southern Division
was 5.3.
