Table I. gives the figures for ages and Wards.
Scarlet Fever was less prevalent than in 1937; the largest
incidence has been in Broad Green, Thornton Heath, and Waddon
Wards. Based on the estimated ward populations, the case rate for
these wards was respectively 436, 344 and 335 per 100,000 of the
population. The age group 6-15 years, as usual, suffered most;
cases in this group comprising 56 per cent, of the total.
The incidence rate of Diphtheria was the same as in 1937;
most cases occurred in Whitehorse Manor, Waddon, and Thornton
Heath Wards. The age group 6-15 years gives the highest
figures, constituting 57.5 per cent, of the total.
No cases of Small Pox occurred during the year.
There were 59 cases of Puerperal Pyrexia; 22 occurred in the
age group 16-25 years and 37 in the age group 26-45 years. A
majority of the cases occurred in women having their first confinement.
Under the Public Health Act, 1936, Puerperal Fever is no
longer notifiable as a clinical entity. All cases of rise of temperature
over 100° F. occurring during the puerperium are now notifiable
under the term Puerperal Pyrexia.
