SCARLET FEVER.
During 1904, in the Borough of Lambeth, 660 cases of Scarlet
Fever were notified, and 16 deaths registered, giving a casemortality
of 2.4 per cent.—4.9 for the Inner, and 1.5 for the
Outer Districts. In 1903, there were 744 cases notified and 23
deaths registered, i.e., a case-mortality of 31 per cent.—6.6 for
the Inner, and 18 for the Outer Districts. The annual averages
for 10 years (1891-1900) in the old Parish of Lambeth are (1)
notified cases 1331.3, and (2) deaths 53.6.
Of the 660 persons notified in the Borough of Lambeth during
1904, 549* (i.e., 83.2 per cent. were removed to Hospital, and of
these, 16 died (i.e., 2.9 per cent.), whereas 111 (i.e., 16.8 per
cent.) were treated at home, and of these, none died. This
difference in case-mortality as between Hospital-and hometreated
patients is to be explained by the greater severity (as a
rule) of the cases sent to Hospital.
The attack-rate and death-rate of Scarlet Fever per 1000 of the
population have been steadily decreasing during the last few
years in Lambeth Parish, and are below the average during 1904
in the Borough—a satisfactory condition of things, which seems
to point to the value of isolation (following notification) as the
chief preventive measure in this disease.
The age and sex incidence and mortality for the 660 Scarlet
Fever cases notified in Lambeth Borough during 1904 are as
follow:—
* Of the 549 cases of Scarlet Fever removed to Hospital, 50 proved not
to be suffering from that disease. These 50 cases must, therefore, be
deducted from the total 660 notified during 1904.
