SCARLET FEVER.
Although there has been an increased prevalence of this disease in the Metropolis as a
whole during the last two years, the number of cases reported in the Borough during each
year has decreased. The variations in prevalence in the Borough and the Metropolis since
1901 are set out below:—

1904 365 —11.9 13,439 + 7.1
1905 277 —24.2 19,469 +44.8
The only year in which the progressive decrease in the Borough was checked was 1903.
During that year there was a high prevalence of the disease in Willesden, the morbidity rate
for that year being 3.90 per 1,000 persons, and 0.14 above that for the preceding
year (3.82).*
The decennial average number (1895-1904) for the Borough is 503, last year's figure
showing a reduction equal to 45 per cent. The complete figures for the Borough and the
Registration Sub-Districts are given below:—

In the St. John Sub-District only does last year's total (59) fail to compare favourably
with all the averages.
On comparing the numbers recorded in each quarter of last year with the averages
for the two preceding quinquennia, it appears that the incidence of the disease was
unequal. Thus, in St. Mary's Sub-District, the cases recorded in the first two quarters were
but slightly below the averages, and the usual autumnal increase was not marked. In
St. John's Sub-District the cases in the second quarter were in excess of the averages,† and
the autumnal increase was almost absent. In North-West Paddington the cases in the first
half of the year were markedly below the averages, while the autumnal increase was fairly
marked.
