During the year 1909, there were 1,403 cases of infectious
diseases compulsorily notified in the Borough; but of these, 83
were subsequently ascertained not to be suffering from the disease
notified, thus reducing the total number of cases of genuine notifiable
infectious disease to 1,320. This shows a decline of 660 cases
on the number notified during the year 1908. The attack-rate for
the year 1909 in respect of the compulsorily notifiable infectious
diseases is, therefore, 56 per 1,000 persons living.
In addition, there were 354 cases of pulmonary tuberculosis
notified under the Public Health (Tuberculosis) Regulations and 58
voluntary cases of phthisis.
The deaths from the seven chief zymotic diseases numbered

per 1,000 persons living in the Borough.
