Scarlet Fever and Diphtheria.—There were 10 " return " cases of Scarlet Fever and one
of Diphtheria during the year. The usual period allowed when speaking of a " Return Case " is
28 days after the return home of a case from Hospital, or 28 days after the release of a case from
isolation at home.
No cases of Diphtheria were notified from North Hyde School during the year.
Some use is made of the Dick reaction in connection with query cases of Scarlet Fever at Mogden
Hospital. Scarlet Fever serum is used in nearly all cases at the hospital.
The Staff of Mogden Hospital is Schick tested and immunised.
Scarlet Fever.—The following table shows the number of cases which have been notified,
and the number and percentage of cases which have been removed to Hospital:—
No. of civil cases notified 391
No. of civil cases removed to Hospitals 344
Percentage of cases removed to Hospitals 87.97
The incident rate of Scarlet Fever in the civil population (84,460) was 4.62 per 1,000. There
were four deaths from this cause during the year.

of cases of Diphtheria removed to Hospital:—
No. of civil cases notified 50
No. of civil cases removed to Hospitals 49
Percentage of cases removed to Hospitals 98.0
The incident rate per 1,000 of the civil population was 0.59. Twelve cases occurred in institutions
during the year. Two deaths occurred from this disease, i.e., a case mortality rate of 4.0 per cent.
The deaths occurred in the following age groups:—
2—3 years 1 5—10 years 1
And in the following months:—

The full details of the Immunisation work for 1933 are set out in the following report by Dr.
Bousfield.
Schick testing has been resorted to in practically every case, and every effort has been made
to ensure that the work is as scientifically accurate as it is possible to make it.
Report of work of the Diphtheria Immunisation Clinics for 1933.
The number of new cases presenting themselves for Schick-testing and Immunisation during
the year was 420.
The total attendances during the year amounted to 2,558.
It would at first appear that less cases have been dealt with at the clinic sessions than in the
year 1932, where the respective numbers were 413 new cases and 3,015 attendances. In this connection
it must however be borne in mind that there had been also a Wednesday afternoon clinic at Hounslow
up to June 29th, 1932, and a Saturday morning clinic at Isleworth until July 16th, 1932, on which
dates both the above clinics were closed down..
The Monday afternoon clinic in 1933 actually dealt with about 85% of the total of attendances
received by the equivalent of approximately two clinics weekly in the year 1932.
Of the 420 new cases (Primary Schick Tests) in 1933:—
367 gave Positive readings,
41 gave confirmed Negative readings,
12 did not attend for reading.
The cases concluded and issued with certificates of apparent immunity during the year amounted
to 384.
Of these 343 persons had been successfully immunised.
41 were found to be naturally immune.
