All cases are carefully investigated, and efforts made to
discover contacts. The school arrangements for the exclusion
of individual children, who have been in contact with cases
of infectious disease, work satisfactorily, there being the
closest co-operation with the Education Department for this
purpose.
There was no special grouping of cases in any particular
school or class, with the exception of an outbreak of diphtheria
at Squires Lane School during the autumn, and it was
found necessary to close the school on account of Notifiable
Infectious Disease for a period of two weeks.
The provision for Hospital isolation, etc., is stated on
pages 73 and 74. Disinfection is at present carried out at
the disinfecting station at the Small-pox Hospital at Summers
Lane.
Wherever infectious disease occurs in the families of
persons connected with the preparation for sale or distribution
of articles of food, especially milk, the greatest care is
exercised to prevent the spread of disease in this way. There
was nothing to suggest that any of the cases which occurred
during 1914 were spread through the agency of water, milk,
or other food.
Scarlet Fever.
120 cases of Scarlet Fever were notified during the year.
A reference to the chart will show that the cases were fairly
evenly spread over the whole year. There was no particular
grouping in any district, and the "spot map" shows that the
cases were scattered throughout the district. The 120 cases
represent infection in 93 houses, as 27 of the cases were
"secondary." 86 cases were removed to hospital: this equals
71.6 per cent. of number notified.
"Return Cases" of Scarlet Fever.
7 cases of Scarlet Fever occurred in 5 houses to which
convalescents had recently returned from the Isolation
Hospital. 2 of these occurred within 7 days of the homecoming
of the alleged infecting patient, 1 within 8 days, 1
within 10 days, 1 within 11 days, and 2 within 14 days. All
