Notifiable Infectious Diseases.
During 1920, under the Notification Clauses of the Public
Health (London; Act, 1891, and the Orders and Regulations
made thereunder, 1,831 cases of infectious diseases (excluding
tuberculosis) were notified, including: cerebro-spinal fever, 7;
acute polio-myelitis, 1; polio-encephalitis, 1; encephalitis
lethargica, 6.
The 2,077 cases notified during 1919 included 699 cases of
measles and 100 of German measles. The compulsory notification
of these diseases was rescinded as from January 1st,
1920. If the number of cases thus notified are deducted from
the total of 2,077, there remain 1,278 cases notified in 1919
comparable with 1,831 notified in 1920, which therefore shows
an increase of 43.3 per cent.
