These 346 cases represent infection in 261 different houses. In
203 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 5 houses where there were “grave”
sanitary defects, and in'15 where the sanitary defects were “slight.”
In arriving at these conclusions I have considered whether any
sanitary defect was of a nature which is generally held by health
officers to predispose to, or directly bring about, the particular disease
in question.
Thus, apart from the measures that have been taken to prevent
the'spread of infectious illness, the notification of euch illness was the
means during the year of bringing about a sanitary inspection of 261
premises.
Table VII shows the number of cases, and of deaths, from the
Infectious Diseases notified during each year since the constitution
of the Borough; and Table Vlll the cases of Infectious Diseases
notified during each month of the year 1911.
The Infectious Sickness Hate of the Borough, excluding the
notifications from Consumption, Chicken-pox, and Ophthalmia, so as
to make the rate comparable with that of former years, was 4.4 to
each 1,000 of the population, as against 3.3 for the preceding yea.'.
The rate in the Northern Division was 3.5, while that in the Southern
Division was 4.8.
