Scarlet Fever followed by Diphtheria.
In one instance a child returned home from hospital after an attack of Scarlet Fever, and
within nine days the father of this child was attacked with Diphtheria An examination was
made of the child, but with negative results; the infection, therefore, was probably due to
some other source.
DIPHTHERIA.
512 cases were notified during the year. On further examination, 113 of these
were subsequently found not to be suffering from tho disease. The corrected number
of cases of Diphtheria was, therefore, 399, equal to an incidence rate of 1.9 per 1000 of population,
as compared with 612 cases, and an incidence rate of 2.9 per 1000 of population, during the
previous year.
The number of deaths certified as being due to Diphtheria during the year was 20, equal
to a death rate of 0.09 per 1000 of population, and a case mortality rate of 5.0 per cent. of the
cases notified.

It will be noticed that in this disease also, both the number of cases notified and the death-rate are considerably lower than those of the three previous years:–
