SECTION V.
PREVALENCE AND CONTROL OF INFECTIOUS DISEASE.
Table XXXII. gives the figures for ages and wards.
The largest incidence of Scarlet Fever has been in Addiscombe,
West Thornton, Broad Green, Norbury and South Norwood Wards.
Based on the estimated ward populations, the case rate for these
five wards was respectively, 448; 404; 363 429; and 264 per
100,000 of the population. The age group 5-15 years, as usual,
suffered most; cases in this group comprising 61.6% of the total.
An unusual number of adults were attacked. Attention is drawn
to this phenomenon in the report on the Borough Hospital.
Diphtheria was most prevalent in Upper Norwood (case rate
448); West Thornton (290); Waddon (316); Whitehorse Manor
(194) and Broad Green (205). Once again the age group 5-15
years gave the highest figures
Twenty four cases of Small Pox occurred, all were of the modified
type. Twelve cases arose in Woodside, but the others were
widely scattered and sporadic.
There were 13 cases of Puerperal Fever and 24 of Puerperal
Pyrexia; 14 occurred in the age group 16-25 years and 23 in the
age group 26-45 years. A majority of the cases occurred in women
having their first confinement.
All the notifiable infectious diseases showed a decreased incidence
with the exception of Small Pox and Ophthalmia Neonatorum.
The notifications of the Pneumonias decreased over 50%,
due to the absence of any severe outbreak of Influenza.
The bulk of the cases of Notifiable Infectious Disease occurred
in the area North of a line drawn from Waddon Station in the
South-West to Woodside Station in the North-East.
The following streets or districts showed the highest incidence
of Scalret Fever, namely, the Corporation Housing Estate,
Waddon; Leighton Street East: Thornton Heath; the area around
Oval Road. Otherwise the cases were widely scattered over the
whole borough area. Diphtheria showed the highest area incidence
in Morland Road owing to an outbreak in a Boys' Home in this
road. Stanley Road : Wilford and adjoining roads and the Waddon
Housing Estate.
The incidence of the commoner infectious diseases in Croydon
during the past seven years is of interest.
