Scarlet Fever.—This disease was again very prevalent
during the year. 1,618 cases were notified, being 294 more than
occurred in 1908, equivalent to an attack-rate of 5.19 per 1,000.
54 deaths occurred, making an annual death-rate of 0.17 per 1,000
the average death-rate for the past 10 years having been 0.11
per 1,000.
Of the notified cases 1,004, or 62 per cent., were removed to the
Plaistow Fever Hospital, an increase of 10 per cent. on the previous
year. Of these 58 cases were subsequently transferred to the
Convalescent Shelter in Manor Road, where the average duration of
residence amounted to 27 days, and on the closing of the Shelter
on 12th March, 453 cases were transferred to the New Convalescent
Home at Harold Wood, where the average duration of stay amounted
to 30 days.
The mixed and other cases received into the Plaistow Hospital
during the year were the following:—Scarlet Fever and Diphtheria 12,
Diphtheria and Measles 8, Diphtheria and Nephritis 1, re-admitted
Diphtheria cases 4, Scarlet Fever and Ringworm 1, Laryngeal Croup 1,
Measles 7, Suspected Typhus 1, Erysipelas 1, Glanders 1, Cutaneous
Anthrax 1, Puerperal Fever 1, Mumps 1, Chicken-pox 1, making a
total of 41.
As a means of noting the epidemic character of Scarlet Fever I
have prepared a chart showing the variation above or below the
monthly average of notifications for each month since the notification
of Infectious Diseases Clauses came into operation. The average
number of notifications for each month during the whole period were
as follows:—January 98, February 78, March 80, April 87, May 90,
June 95, July 102, August 101, September 135, October 168,
November 130, December 107.
Diphtheria.—The numberof cases of this disease notified during
1909 was 472, being the smallest number notified in any one year
