vaccination had died out, revaccinated, and to the practical help given generally
by the executive authorities. In the districts of Dacca, Chittagong, Mymen¬
singh and Tippera, the increase was due to outbreaks of small-pox necessitat-
ing a large number of persons being vaccinated.
As regards the decrease, the Civil Surgeon of Bakarganj attributes it to
the aversion of the Ferazi Muhammadans to vaccination, and to the difficulty
in getting good vaccinators, owing to the trouble in realizing the vaccinators'
fees and to the bad behaviour of the people. In Faridpur, the decrease
is reported to be due partly to the fact that a large number of Ferazi
Muhammadans had been vaccinated during the previous year, leaving a fewer
number of persons unprotected during the year, and also partly to prevalence
of malarial fever during the working season. In Khulna, it was due to illness
among the vaccinators, and also to the fact that a large number of unprotect-
ed persons had been vaccinated during 1911-12, leaving fewer subjects for
vaccination during the past year. Malaria is reported to have retarded vacci-
nation in Bankura and Murshidabad ; the Civil Surgeon of the latter district
makes the inspecting staff also responsible for the decrease. In Rajshahi,
the decrease was due partly to absence of small-pox in epidemic form, and
partly to the opposition of the Ferazi Muhammadans. The Civil Surgeon of
Pabna attributes the decrease to greater prevalence of malarial fever, which
rendered vaccination in most of the thanas extremely difficult, while in Malda
it is reported to be due to the smaller number of surviving infants available
for vaccination.
5. Vaccination in Municipalities.—In Calcutta, 33,223 operations were
performed during the year, against 32,187 during 1911-12.
In mufassal municipalities, dispensaries, etc., the number of cases
amounted to 94,287, against 86,369 during the previous year. The average
number of parsons vaccinated by a vaccinator in mufassal municipalities was
708, against 713, while that done by licensed and paid vaccinators was 1,375
and 775, against 1,365 and 747, respectively, in the previous year.
6. Protection afforded to Infants—During the past year, out of
1,316,699, the estimated number of infants under one year available for
vaccination, 633,057, that is, 480.79 per thousand, were successfully vaccinat-
ed. In 13 districts, the protection was over 500 per mille, while in 14
districts it was below this standard. The Eastern Bengal districts are for
the most part responsible for the low rate of infant protection, and steps
are being taken to ensure better results in future.
The protection afforded to infants in municipalities is shewn in Appendix
VII attached to the report. It will be seen that 752.06 per mille of the
surviving infant population was protected during the past year. The atten-
tion of Civil Surgeons has, as usual, been drawn to their responsibility in the
matter of infant vaccination in towns wherever the protection is inadequate.
7. Recess work.—During the recess or non-working season of 1912-13,
112,955 operations were performed in connection with small-pox epidemics.
8. Six-puncture vaccination.—The total number of successful primary
and revaccination operations in six points in this Presidency was 333,903 and
7,563, respectively, against 273,402 and 3,301, during 1911-12, in the districts
of the Burdwan and Presidency Divisions and in the district of Darjeeling.
The six-puncture system of vaccination was not in force in the districts of
Eastern Bengal, but it has been introduced there during the year under
report. and hence the comparatively smaller number of operations done.
9. Factory and Tea Garden vaccination.—During 1912-13 the total
number of primary and revaccination operations performed in factories and
tea gardens in Bengal amounted to 3,386 and 1,291, respectively, against
2,752 and 665 in the previous year.
10. Cost of and contribution towards vaccination.—The cost of
vaccination during the year was Rs. 1,72,212-3-9. against Rs. 1,67,767-3-11
in the previous year. The average cost of each successful case of vaccina-
tion was one anna and six pies, against one anna and five pies.
The District Boards and Cantonments contributed Rs. 2,344-8-4 and
Rs. 72, against Rs. 2,499-8-3 and Rs. 79-13-6, respectively, in the previous
year.
