Scarlet Fever.
Scarlet fever was slightly less prevalent during 1924 than in
the previous year, 378 cases having been notified as compared with
409 in 1923, 750 in 1922, and 1,374 in 1921. We are again at the
base of the wave of cyclical epidemicity which commenced in 1919,
reached its apex of maximal intensity in 1921, and then gradually
declined. The case-rate per 1,000 of the population was 2.2, and
three deaths were registered from the disease, giving a death-rate
of .018 per 1,000 as compared with 6 deaths and a death-rate of
.035 in 1923, and 13 deaths and a death-rate of .077 in 1922.
Of the cases notified 352 (i.e., 93.1 per cent.) were removed
to hospital. The infected houses numbered 326.
In 25 of the notified cases (not included in the above total)
the diagnosis of scarlet fever was not confirmed at hospital.
Diphtheria.
The number of cases of diphtheria notified during 1924 was
372 as compared with 374 in 1923, 670 in 1922, and 713 in 1921.
The number of deaths registered from the disease was 25,
giving a death rate of 0.15 as compared with 34 deaths and a death
rate of 0.20 in 1923, and 58 deaths and a death rate of 0.34 in
1922.
