NOTIFIABLE INFECTIOUS DISEASES.
The infectious diseases notifiable under Section 55 of the
Public Health (London) Act, 1891, are:—Small-Pox, Cholera,
Diphtheria, Membranous Croup, Erysipelas, the diseases
known as Scarlatina or Scarlet Fever, and the Fevers known
by any of the following names:—Typhus, Typhoid, Enteric,
Relapsing, Continued or Puerperal; Cerebro-Spinal Meningitis,
Ophthalmia Neonatorum, and Acute Polio-Myelitis or PolioEncephalitis.
The total number of cases notified during the year 1912
amounted to 1043, of which number 811, or 77.67 per cent.
were removed for isolation to the Metropolitan Asylums Board's
Hospitals or other Institutions. In 24 instances, or 2.95
per cent. of the cases removed, the Hospital authorities returned
the patient as not suffering from any notifiable disease. Deducting
these from the gross total, we have a corrected total
of 1019 cases of infectious disease notified as occurring in the
Borough during the year, an increase of 174 compared with
the total for the preceding year, which was 835. In 1910, 848
cases were notified.
Age Periods.—51.19 per cent. of the Scarlet Fever cases,
compared with 41.21 per cent. in 1911, and 46.54 per cent. of
the Diphtheria cases, compared with 49.84 per cent. in 1911,
occurred among children aged six years and under.
