prevalence of plague and in Muzaffarnagar, illness of a vaccinator for six weeks,
dismissal of a vaccinator for fictitious work and prevalence of plague and relapsing
fever were the chief factors. In Unao the decrease is said to be due to the fact
that the lymph received during the first two weeks of October proved inert. This
was largely due to the heat experienced by the lymph in transit but to a certain
extent to the heat at the lymph dépôt in September during the inoculation period
of the calves and the time during which glycerinated lymph is kept before issue.
In future with the installation of a cold storage plant at the dépôt and the use of
chloroformed lymph to kill adventitious bacteria the lymph issued early in the
season will be of better quality.
Successful vaccination and degree
of protection afforded.
(Statement I.)
3. In 37 districts out of 48, the number of persons successfully vaccinated
per mille of population in 1913-14 was in excess of
that of the preceding year.
Of the best protected districts Garhwal as usual stands first with 79.08
against 68'31 in 1912-13 and 57.81 in the preceding year, the average annua
number of persons successfully vaccinated, and the average annual death-ratl
from small-pox, per 1,000 of population during the previous five years being 80.30
and .01 respectively. Naini Tal comes next with 61.96, 61.49 and 56.13 followed
by Almora with 58.92, 51.98 and 50.52, Jhansi with 49.97, 50.23 and 47.74 and
Hamirpur with 46.23, 45.92 and 45.77 persons successfully vaccinated per mille of
population in 1913-14, 1912-13 and 1911-12 respectively. The average annual
number of persons successfully vaccinated, and the average annual death-rate
from small-pox, per 1,000 of population during the previous five years, in these
districts were 57.89, 54.54, 47.56 and 44.05 and .14, .20, .04 and .03 respectively.
Amongst the worst protected districts, i.e. showing a low number of persons
successfully vaccinated per mille of population, the most conspicuous are
Farrukhabad with 22.00, 21.72 and 21.01, Bara Banki with 22.78,22.68 and 21.73,
Sultanpur with 24.25, 24.00 and 23.91 and Azamgarh with 25 60, 25.58 and 22.24
respectively in 1913-14, 1912-13 and 1911-12. The average annual number of
persons successfully vaccinated and the average annual death-rate from small-pox
per 1,000 of population during the previous five years were in Farrukhabad 18.85 and
.12, in Bara Banki 19.51 and .30, in Sultanpur 23.56 and 1.11 and in Azamgarh
22.87 and .59. Of these districts Farrukhabad, Bara Banki and Azamgarh were
noted in the previous triennial report as amongst the districts showing the lowest
number of protected persons per mille of population. Though all these districts
show an improvement over the preceding two years and over the normal, special
endeavours should be made to raise them from the unenviable position they have
retained during the last six years.
Vaccination in proportion to
births and according to age.
9. The number of successful primary vaccinations in proportion to births
in 1913-14 was 45.37 per cent. for children under
one year of age, 17.66 per cent. for children between
the ages of one and under six years and 64.99 per cent. for all age periods as
compared with 46.47, 17.72 and 66.25 respectively in 1912-13 and 45.87, 17.42
and 65.42 in 1911-12.
The number of successful operations on children under one year of age in
proportion to births for the years 1913-14, 1912-13 and 1911-12, was in the first
range 56.77 per cent., 57.22 per cent. and 57.07 per cent. respectively. In the
second range it was 36.75 per cent., 39.68 per cent. and 38.99 per cent., in the
third range, 47.99 per cent., 47.99 per cent. and 48.57 per cent., and in the fourth
range, 37.81 per cent., 37.99 per cent. and 37.36 per cent. respectively. From
this it will be noted that the percentage of operations to births was highest in the
first range. Although the percentages during the last year were lower owing to
high birth-rates, the number of successful vaccinations performed on children
under one year of age was higher than in the preceding two years.
As explained above,there were only two circles in 1911-12 but for the purposes
of comparison statistics have been prepared for the four ranges.
Mortality from small-pox.
10. In 1913 the death-rate from small-pox was .17 per mille of population
against .07 in 1912 and .03 in 1911 and .30 the
quinquennial average.
