age period. Allowing for errors in diagnosis, the mortality was 7.0 per cent.
Amongst persons over five years of age the mortality was 0.5, allowing for errors
in diagnosis. The case mortality for the year is the lowest so far recorded for
the Borough.

In 157 of the cases the patients were children attending school, and in 131 of
these they were at school within a week of being certified as having the disease.
As noted in previous years, there were instances in which the children were at school
whilst suffering from diphtheria, before the nature of their illness was recognised.
In 169 other cases, although the patients themselves were not school-going children,
there were other children in the houses who were. In 36 instances the histories showed
that there had been cases of "sore throat" amongst the inmates of the houses in
which the patients resided. In 38 instances there was evidence pointing to infection
from previous cases in the Borough. In 273 instances the houses were occupied by
members of more than one family, in 63 by single families, and in 29 instances the
cases occurred in artisans' dwellings of the block type. With regard to the sanitary
condition of the dwellings, in 233 this was satisfactory, in 46 fairly so, and in 86
it was unsatisfactory, but these figures must not be taken as an indication that a
satisfactory condition is favourable to the occurrence of diphtheria in houses ; their
significance has been referred to in previous reports.
