SCARLET FEVER.—The total number of cases notified
during the year amounted to 466, compared with 348 in 1911.
Of this number, 392, or 84.12 per cent., were removed to
the Metropolitan Asylums Board's Hospitals. Subsequently 7
cases were returned to their homes and stated not to be suffering
from any notifiable disease. Deducting this number, a corrected
total of 459 is obtained, compared with 337 in 1911, equal to
an attack rate of 2.78 per 1,000 persons, compared with 2.09 in
1911. The attack rate for the County of London was 2.51 per
1,000.
An examination of the attack rates for the various Wards
of the Borough shows that the highest occurred in Blackheath
Ward (4.28 per 1,000) and that the Ward least affected
was South, with 1.55 per 1,000.
45.10 per cent. of the cases occurred among children
between the ages of 5 and 10 years, and 27.01 per cent.
among children under the age of five.
Case Mortality.—Six deaths from Scarlet Fever
occurred to residents in the Borough, equal to 1.30 per cent. of
the cases notified, compared with 1.48 in the previous year.
DIPHTHERIA.—Four hundred and thirty-four cases of
Diphtheria were notified, compared with 342 in 1911, and of this
number 372, or 85.71 per cent., were removed to hospital.
Fifteen patients (or 4.03 per cent. of the number removed) were
returned as not suffering, giving a corrected total of 419, an increase
of 90 on the number notified in 1911. The attack rate per
1,000 of the population amounted to 254, compared with 2.04 in
1911. The rate for the County of London was 1.58 per 1,000.
