NOTIFICATION OF INFECTIOUS DISEASES.
Small Pox, Scarlet Fever, Diphtheria, Membranous Croup, Enteric or
Typhoid Fever, Erysipelas, Continued Fever, Relapsing Fever and Cholera.
These are the infectious diseases which medical practitioners and parents and
guardians, or those having charge of patients, are compelled to notify to the
sanitary authority of Islington under the provisions of section 55 of the Public
Health (London) Act, 1891.
During the year under observation the number of notifications was 2,275,
or 347 more than were made known in the preceding year. They are, however,
375 below the corrected average of the preceding 10 years (Vide Table XCV).
The notified cases in proportion to the population represent an attack-rate
of 659 per 1,000 of the inhabitants, which is slightly in excess of the rate of
the preceding year, when it was 5.62, but below that of the preceding 15 years,
during which it averaged 8.6 per 1,000. There is, therefore, a decrease of 20.1
in the rate.
The return is particularly satisfactory, as with the exception of Scarlet
Fever, all the diseases were below the average records, after correction for
increase of population, of the preceding 10 years, and even in the case of
Scarlet Fever, the increase (20) was so small that it is hardly worthy of consideration.
Thus Small Pox was 41 below the average, Diphtheria as many as
239, Enteric Fever 79, Erysipelas 33, and Continued Fever 2, while Typhus
Fever and Puerperal Fever remained at the average.
The returns for the County of London show that there were 35,340 notifications,
which represent an attack-rate of 7.48 per 1,000 of the population
of the metropolis.
In the Encircling Boroughs 5,956 cases were notified, which are equal to
an attack-rate of 7.25 per 1,000 of the inhabitants.
