Diphtheria.
The cases of diphtheria notified in the administrative County of London in 1900 numbered
12,023, compared with 13,711 in 1899. The number of deaths registered from this cause
in 1900 was 1,540, compared with 1,946 in 1899.

The diphtheria case rates and death rates in 1900 and preceding periods are shown in the following table—

18990.4313.114.2
19000.3412.712.8

The death-rate in each year since 1858, in relation to the mean death-rate of the period
1859-1900, is shown for diphtheria and for diphtheria and croup combined in diagram XII., and
the monthly case-rate and case mortality in each of the years 1891-1900 in relation to the mean
of the whole period is shown in diagram XIV. The relation of diphtheria mortality to season
will be seen on reference to diagram V. (D.), page 15, showing the average weekly number of deaths
from this disease in the 40 years 1861-1900.
If the London diphtheria death-rate be compared with the death-rates of the following
large English towns it will be seen that in the period 1890-9 the London rate exceeded the
rates of all these towns except West Ham, and in 1900 exceeded the rates of all except Leeds,
Sheffield. Salford and West Ham.

*In the preparation of this table, the question whether the persons, who were attacked and who died, belonged to London is
disregarded, the percentage being calculated on the number of cases notified in London, and the number of deaths occurring in London
and the institutions belonging to London. Inasmuch as the age of the patient is not in all cases recorded in the notification certificate
it has been necessary to distribute such cases among the various ages proportionately.
†The Infectious Diseases (Notification) Act only came into force in 1889.
