PREVALENCE OF AND CONTROL OVER
INFECTIOUS DISEASES.
INFECTIOUS DISEASES GENERALLY.
Table IV. shows the total number of cases of infectious disease
(excluding Tuberculosis) notified during the year, the distribution
by age-groups and the number of cases admitted to hospitals.
Notifications.—The total number of cases of infectious
disease, excluding tuberculosis, notified during the year was 489,
as compared with 682 for the year 1930 . 223 notifications were
in respect of chickenpox, which continued to be notifiable in the
Borough throughout the year.
Smallpox.—The prevalence of Smallpox decreased generally
throughout the Metropolis during 1931, and in the Borough only
1 notification in respect of this disease was received, as compared
vvith 29 the previous year. The case was a mild one, and
on investigation it was found that the patient had been in
contact with a case of smallpox while residing in another area.
Owing to the prevalence of the disease in the Metropolis, a
number of contacts who reside or work in the Borough had to be
kept under observation during the year.
During the year the Inspectors paid 320 visits to Smallpox
contacts.
Cases of chickenpox reported from the Schools, medical
practitioners, and through other sources were visited by the Medical
Officer and the diagnosis confirmed in each case.
