THE NOTIFICATION, ISOLATION, FATALITY,
and
PREVENTION OF INFECTIOUS DISEASES.
Under the Provisions of the Public Health (London) Act, 1891.
The Principal Diseases Comprise:—
Small Pox, Scarlet Fever, Diphtheria, Membranous Croup, Enteric Fever,
Typhus Fever, Continued Fever, Erysipelas and Puerperal Fever.
There were 2,853 cases of the diseases which are notifiable under the
Public Health (London) Act, 1891, in addition to which there were other
communicable ailments, such as Tuberculosis, Ophthalmia Neonatorum,
Acute Poliomyelitis, Cerebro-Spinal Fever, Encephalitis Lethargica, Measles,
Malaria and Dysentery, which are notifiable either under Orders of the late
Local Government Board, or of the London County Council with the approval
of that Board.
The total cases notified are 860 above those of the previous year (1,993),
and 1053 more than the average of the preceding ten years. The largest
increases when contrasted with the decennial averages are to be found in the
returns from Scarlet Fever and Diphtheria, which were respectively 359 and
755 in excess, while the other diseases all showed a decrease.
The 2,853 cases were equal to an attack-rate of 8.49 per 1,000 of the civil
population.
In London the attack-rate was 8.81 per 1,000 of the civil population, or 0.32
more than in Islington, while in the Encircling Boroughs it was 10.05, or 1.56
above the local rate.
