PREVALENCE OF, AND CONTROL OVER, INFECTIOUS
DISEASES.
NOTIFICATIONS.
The total number of notifications (including duplicates)
received during the year was 3,611, as compared with 2,743
in 1920. This increase is largely due to the fact that there
were serious outbreaks of scarlet fever, diphtheria and zymotic
enteritis. The outbreaks of scarlet fever and diphtheria are
the largest known in the records of the Borough, and were
general throughout the County of London. The scarlet fever
epidemic was mild in character, but the mortality from diphtheria
was above the average. The figures for zymotic
enteritis are large, but compared with 1911, when 866 notifications
were received, they show a distinct improvement.
In 1911 the summer was hot and dry, and compares with
the summer of the year under review, when 454 notifications
were received. If we only consider children under 1 year,
265 notifications were received in 1911, compared with 155 in
1921.
Table IV. shows notifications in detail for each disease and
in the age groups. It also shows the numbers occurring in
each parish of the Borough and the numbers removed to
hospital. For comparative purposes the number of cases of
notifiable infectious diseases occurring in the Borough each
year since 1901 is shown in Table No. 27 on page 60.
