SPECIFIC INFECTIOUS DISEASE.
During the year 1913 there were 1,126 cases of acute infectious
disease compulsorily notified in the Borough ; of these 81 were
found subsequently not to be suffering from infectious disease, thus
reducing the number of genuine cases to 1,045. This total shows
an increase of 21 cases upon the total notified during 1912. The
attack-rate in respect of the acute notifiable infectious diseases
for the year is therefore 4.7 per 1,000 persons living.
In addition, I received 681 notifications of pulmonary
tuberculosis and 253 notifications of other forms of tuberculosis.
The deaths from the chief zymotic diseases numbered 255.
This is equal to a zymotic death-rate of 1.1 per 1,000 living
in the Borough.
A.—NOTIFIABLE INFECTIOUS DISEASES (ACUTE).
Small-pox.—No case of this disease was notified in the Borough
during 1913.
Scarlet Fever or Scarlatina.—The number of cases of this
disease notified during the year was 807, but of these 30 were
afterwards found not to have suffered from this disease. The
genuine cases therefore amounted to 777. This is an increase of
271 cases upon the genuine cases notified during 1912. On
reference to the chart given with this report, it will be noted that
a slight rise in the incidence of this disease took place in the beginning
of May which was maintained until the end of August. In the
second week of September a considerable rise took place which
increased during the months of October, November and December;
but fell, however, almost to normal in the last week of December.
The rise began as usual early in the month of September.
The attack-rate for 1913 is 3.4 per 1,000 persons living.
The number of cases of scarlet fever removed to hospital
during the year was 747. This is equal to 92 per cent. of the
total notified.
