CLASS I. -ZYMOTIC DISEASES.
Principal Zymotic Diseases.
The principal zymotic diseases are seven in number, viz.,
smallpox, measles, scarlet fever, diphtheria (including membranous
croup), whooping cough, “fever” (including typhus,
typhoid or enteric, and simple, or relapsing, or continued),
and diarrhcea; and the zymotic death-rate is made up from
the total deaths from these diseases.
In the Borough, during 1913, there were registered
400 deaths from the seven zymotic diseases, and of these
110 are strangers belonging to other districts, and 290
parishioners who died within the Borough. 79 parishioners,
however, died from the seven principal zymotic diseases
outside the Borough. Subtracting the strangers, and adding
on the parishioners who died without the Borough, there is a
corrected total of 369, giving a zymotic corrected death-rate
of 1.2 per 1,000 inhabitants. The yearly averages of the
numbers of deaths (corrected) from the 7 principal zymotic
diseases for the two decennia 1891-1900 (Parish), and 19011910
(Borough), are respectively 679.6 and 475.1.
As a test of the sanitary condition of a community, the
zymotic death-rate is of approximate value, and in this
respect Lambeth Borough stands well.
The zymotic death-rates (corrected) for the different
Registration Sub-Districts vary as shown in Tables
D (1) and H (1) which, in addition, give the general
death-rates. Lambeth Church shows the highest, and
Norwood the lowest zymotic death-rates respectively.
The corrected zymotic death-rate for the Inner Districts
is 2.1, and for the Outer 0.7—a difference explainable, as
before, by the crowding and absence of proper means of
home isolation and nursing in the former, as compared
with the latter districts. Crowded districts naturally suffer
more in this respect than those more sparsely populated.
