PREVALENCE OF AND CONTROL OVER
INFECTIOUS DISEASE.
NOTIFICATIONS.
45. The total number of notifications (including duplicates)
received during the year was 2,743 as compared with 3,461
in 1919. This decrease is largely accounted for by the fact
that measles ceased to be notifiable at the end of 1919. The
number of notifications of measles shewn in Table IV. below
represents voluntary notifications instead of compulsory ones
as in the previous year.
Table IV. shows notifications in detail for each disease
and in the age groups. It also shows the numbers occurring
in each parish in 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 28 on page 69.
There is an increase in the incidence of scarlet fever,
and of puerperal fever, but a decrease in tuberculosis.
