INFECTIVE DISEASES.
The number of deaths from notifiable infectious diseases,
including all forms of tuberculosis, was 182.
From all infective diseases the death-rate was .55 per 1,000—
.54 in Putney, .44 in Central, .66 in Clapham, and .57 in
Streatham.
Table V shows the number of cases of the notifiable infective
diseases reported, arranged in various age groups, and Table VI
shows the same figures arranged in the sub-districts in which they
occurred.
Smallpox.
No case occurred in the Borough during the year.
Following the arrival in London on the 2nd April of the S.S
"Mooltan." from which were removed two fatal cases of smallpox,
close supervision was kept on all passengers and crew who
subsequently came into the Borough. None of these persons
developed the disease
Diphtheria.
Seven cases were confirmed compared with 16 in 1948 and 46
in 1947. Forty other cases were reported, but after admission
to hospital were found to be incorrectly diagnosed. There were
no deaths.
Scarlet Fever.
495 cases of Scarlet Fever were notified or reported compared
with 452 in 1948, 343 in 1947 and 356 in 1946. The diagnosis
was not confirmed in ten cases.
The increase in the number of cases has been associated with
a general increase in the incidence of this disease throughout
London.
There were no deaths from the disease in 1949 as in 1948.
Of the total number of cases, 193 or 38.6 per cent. were
removed to hospital.
Whooping Cough.
611 cases were notified during the year. There were 3 deaths.
