ERYSIPELAS
Erysipelas was the cause of 185 cases, which were equal to an attack-rate
of 0.57 per 1,000 inhabitants. This rate is 0.70 below the mean rate of
the 10 years, 1902-11. It is also lower than any rate recorded in those
years, and indeed, since 1891; for on referring to the returns of past years
the Medical Officer of Health finds that in the decennial period, 1891-1900,
the corrected average number of cases was 245; while the lowest return for
any year was 184, and the highest 353. In the succeeding decennium,
1901-10, the cases averaged 256 per annum, while the lowest number of
cases notified in any of these years was 212, and the largest 357. In
1911 they numbered 275.
Hospital Isolation —Of the 185 cases notified, 45 were treated in
hospital, so that only 24.3 per cent. were isolated. This figure is, however,
slightly more than the percentage isolated in the preceding year, when it was
22.6.
Fatality.— As only 5 deaths were registered, the fatality was 2.7 per
100 cases.
