THE 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 2,064 cases of these diseases were notified, or 438 less
than the average, after correction had been made for the increase of population,
of the preceding ten years. The return is also 228 below the return for 1900
The decrease in the notified cases is not confined to one or two diseases,
but is common to all, and therefore it is that the return is so satisfactory. In proportion
to population, the cases were 1.27 per 1,000 below the average, the
attack rate being 5.94, as against a decennial rate or T.21 per 1,000 inhabitants.
