Notifications.
2,952 cases of Infectious Disease (Smallpox 101) were notified during
the year. In addition there were 120 other cases notified as Infectious
Diseases in which the diagnosis was not confirmed.
The notification rate was 18.9, compared with 24.4 in 1930.
The incidence of the commoner infectious diseases generally was less
than in 1930; particularly so in the following diseases:—
(a) Smallpox 527 fewer cases.
(b) Diphtheria 230 ,, ,,
(c) Scarlet Fever 78 ,, ,,
The only disease in which there was an increase during the year was
Pneumonia (no cases more than in 1930), and the higher incidence coincided
roughly with the weeks of greatest fog.
On investigation none of the infectious diseases showed any tendency
to grouping as a result of common sources of infection. In the main
cases occurred sporadically throughout the Borough.
Infectious Diseases in Milkshops and Homeworkers' Premises.
Two contacts of infectious disease patients (1 Diphtheria, and
1 Scarlet Fever) employed in the milk trade were dealt with during the

was served.

5 Diphtheria, 9 Scarlet Fever, 3 Chickenpox and 1 Measles.
No notice was served under the Factory and Workshop Act, 1901,

was discontinued, and any work found on the premises was disinfected
before being returned.
