PREVALENCE OF AND CONTROL OVER
INFECTIOUS AND OTHER DISEASES.
SCARLET FEVER.
There was an increase in the incidence of scarlet
fever, ninety-six cases being notified, a rate of 2.42 per
1,000 population. Eighty-eight cases were treated in
hospital, and seven cases at home. In addition eight
suspected cases were admitted to hospital where it was
later decided that the illness was not scarlet fever.
During the early summer months there was an abnormal
incidence of cases (twenty-three in all) at the Burlington
Road Infants' and Junior Schools. Throat swabs taken
at the time showed a high proportion of hemolytic
streptococcal carriers among the scholars. Seventy-six of
the total number of cases occurred as single cases in a
house. There was only one example of " return case "
infection.
DIPHTHERIA.
The diphtheria incidence was 0.15 per 1,000 population.
This is very much lower than that of the past few
years. Six cases were notified, and all except one were
treated in hospital. None of the cases had been
immunised. In addition, three " carriers" received
hospital treatment.
The following statistics refer to immunisation carried
out during the year. No change has been made in the
scheme as previously reported.
