It will thus bo seen from this table that for the period 1905 to 1912
the percentage of children vaccinated has declined from 83.1 to 67.0,
this being equivalent to a decrease of 19 per cent. The number of
unvaccinated persons must be therefore rapidly increasing, and during
the past few years have added a not inconsiderable number to the
unvaccinated population, the presence of whom is a factor of which
public health administrators must never lose sight,
Diphtheria and Membranous Croup.
The number of cases notified in 1913 was 116, as compared with
155 in 1912, the attack-rate, or number of cases notified per 1000
population being 1.34, as compared with the rate of l.80 in the previous
year. The number of fatal cases was 3, or 2.6 per cent, of the cases
notified, as against 11.0 per cent. in 1912. The death-rate per
1000 population was 0.03; 98 patients, or 84 per cent, of the total cases
notified, were removed to hospital.
