Notifiable Infectious Diseases.

ENTERIC FEVER.
No case of Enteric Fever occurred in the District during 1922.
The comparative freedom of the District from Enteric Fever is
significant and is undoubtedly due to the safety of the water supply
and to the almost universal adoption throughout the District of a
water carriage system of sewage disposal. Cases occurring in the
District are generally contracted outside the District, often in less
sanitary areas, and the disease, once imported, does not gain a
foothold.
The cases notified during the previous 5 years were 6, 0, 0,
3 and 1 respectively.
Comparative figures are:—Incidence Rate (cases per 1,000 of
population)—Barnes, 0.00; London, 0.06; England and Wales,
0.06. Mortality Rate per 100 cases—Barnes, 00 per cent.;
London, 16.6 per cent; England and Wales, 18.0 per cent.
SMALL-POX.
No case of Small-pox occurred in this District. During the
year 962 cases were notified in England and Wales, and the disease
was present in the Country throughout the year. An outbreak
occurred in the County of London in September, and cases
continued to arise in London, and in some of the surrounding
Sanitary Districts, until the end of the year; in all 62 cases were
notified in London, and 20 of these cases proved fatal. In view of
the occurrence of cases of Small-pox in neighbouring Sanitary
Areas, special preventive measures were taken in the District.
The public were informed by posters and handbills of the importance
of protecting themselves and their children by vaccination,
or re-vaccination; contacts coming into the area were kept closely
under observation, and as Chicken-pox was prevalent at this time,
cases of the disease which were not being medically attended, were
visited to ensure that a mild case of modified Small-pox should not
escape detection by being mistaken for one of Chicken pox.
