In addition to the surveillance of contacts of the cases notified
to the department, it was also necessary to keep under surveillance
a number of other persons who had been in contact with confirmed
cases resident in other areas.
Scarlet Fever
One hundred and thirty-six cases were notified compared with
89 in 1963 and 109 in 1962.
No deaths occurred.
Puerperal Pyrexia
During the year 25 cases were notified, of which 22 occurred in
hospital and three at home. Four of the hospital notifications
referred to patients whose home addresses were outside the
Borough.
Sonne Dysentery
Investigation and systematic follow-up of all cases of dysentery,
in which general practitioners co-operated fully with the Health
Department, continued throughout the year and where it was considered
necessary, stool specimens were obtained from family
contacts for bacteriological examination.
Approximately two-thirds of the total cases for the year were
single unrelated cases and the remaining cases were made up of
minor outbreaks which occurred at two day nurseries in the
borough. Details of these minor outbreaks are given below :

reflect fully the amount of work involved on visiting and following
up. Many other cases reported as dysentery were investigated.
Most of these proved negative on bacteriological examination.

Influenza, Acute Influenzal Pneumonia and
Acute Primary Pneumonia
Acute influenzal pneumonia and acute primary pneumonia are
