measles. 31
The 1,374 cases of measles occurred in 759 houses, averaging 1.8 cases per house, as compared
with 1.7, 19, and 1.8 in the years 1911, 1910, and 1909 respectively. There were in all
615 secondary attacks, equal to 44 7 per of the total known cases, as compared with 43.7
per in 1911, 46.8 in 1910, and 44.9 in 1909. The house distribution of the known attacks
in each of the past six years is shown below :—

The deaths entered as due to this disease, including a number certified as due to bronchitis
broncho-pneumonia, &c., but allocated to measles after special inquiry, number 32, 16 of each
sex. The fatality observed last year was at the rate of 2.3 per of known cases (24 for
males and 2.2 for females). Such fatalities are the lowest recorded during the six years. (Seebelow.)

In Table 19 (page 34) will be found the Ward distribution of known cases and deaths,,
together with the equivalent fatalities. That table should be considered with the first part of
Table 23 (page 35), and as regards cases, the numbers should be accepted with some reservation,
as it is practically certain that known cases are not in the same ratios to actual occurrences
in all the Wards. Taking the figures given in Table 19 as they stand, it will be noted that
the fatalities recorded last year were generally less than the averages for 1907-11, except in
Westbourne and Hyde Park Wards. Last years fatalities were higher than in 1911 in four out
of the eight Wards.
The sex-age-group fatalities (Table 20) were, with two exceptions (females, 1-2 and 3-4),
lower last year than in 1911, and in every case less than the averages.
The 32 deaths recorded during the year were equivalent to a mortality of 022 per 1,000
persons of all ages, as compared with a rate of 0.5 in 1911 and an average of 0.3. (See below!)
The mortality, according to the data published in the Quarterly Reports of the RegistrarGeneral
(Table 13), was 0 25 per 1,000 and the mean mortality 0 31. In the County as a whole
the mortality was 040, and in St. Marylebone 0 34, the only rates in excess of the local. In
Westminster and St. Marylebone the rates recorded last year exceeded the averages, but in all the
other instances they were below.

The mortality rates recorded in the Wards (Table 23) suggest that the disease was unduly
prevalent in certain parts of the Borough, last years rates being in excess of the averages in
Queens Park and Westbourne Wards. Last years rates were notably above those of 1911 in
Queens Park, Harrow Road, and Hyde Park Wards..
