Total operations done by all establish-
ments.—Statement No. I.
6. The total number, of operations performed by all establishments dur-
ing the triennial period 1914—17 was 2,600,325
against 2,812,605 in 1911—14, showing a decrease
of 38,042 in primary and 174,238 in revaccina-
tion. The decrease in revaccination in 1914-15 and in primary vaccination last
year was, as already reported, due in the former to the increased demand for
revaccination on account of the prevalence of small-pox in 1913-14 and in the
latter to the diminution in the number of children available for the operation,
but during the year under report there has been an increase in both primary
and revaccination, viz., 36,102 and 17,488, respectively, as compared with the
figures for the previous year. This increase is most satisfactory and reflects
credit on those concerned, i.e., in regard to primary the District and Special and
as to revaccination the District and Cantonment Staffs. Though there is a
decrease of 212,280 operations as compared with the previous triennial period it
must not be assumed that the number performed in the one under record is
small; it was really due to the prevalence of small-pox in the preceding triennium
that so many operations were performed, constituting practically a record for
the Punjab. Compared with the figures for triennial periods previous to the
last there have been increases amounting to 495,816, 438,684 and 527,905, res-
pectively, as against those for 1908—11, 1905—08 and 1902-05.
House-to-house vaccination.
7. There was a total of 20,227 operations performed under the house-
to-house system in 11 districts, viz., 2,808 in
Hissar, 383 in Gurgaon, 1,140 in Karnal, 800
in Ferozepore, 9,143 in Lahore including 7,343 in the Lahore Municipality,
1,148 in Shahpur, 192 in Jhelum, 1,487 in Montgomery, 500 in Lyallpur,
1,748 in Jhang and 878 in Muzaffargarh.
District Staff.—Statement No. I.
8. In the triennial period under report the number of operations per-
formed by the District Staff amounted to 2,420,746 as
against 2,603,950 during the preceding triennium. Of
the total number of operations 1,939,143 were primary and 481,603 revaccination,
showing a decrease of 42,805 in the former and 140,399 in the latter as com-
pared with the triennial period 1911—14. Compared with the previous year,
however, there was an increase of 27,311 in primary and 17 303 in revaccina-
tion. In 18 districts an excess was recorded in primary vaccination, most
marked in Karnal where it amounted to 5,929 ; next to this came Gurgaon with
an increase of 3,640 ; increases of more than 3,000 were recorded in Ludhiana,
Dera Ghazi Khan, Jullundur, Ferozopore and Montgomery ; and in 11 others the
excess varied between 63 in Simla and 1,887 in Lahore. On the other hand,
there was a decrease in 10 districts, those in which it was marked being Kangra
1,971, Gujrat 1,939 and Rohtak 1,501 and in 7 others it varied between 161 in
Jhelum and 967 in Shahpur. In Kangra the decrease was due to a reduction
in the number of births during the year and in Gujrat, Rohtak, Shahpur,
Jhelum, Rawalpindi, Attock and Lyallpur due to the fact that from these
districts vaccinators who were sent for training to the Punjab Vaccine Institute
at Lahore were replaced by vaccinators from the Special Staff whose work is
shown separately ; if their work had been included there would have been an
increase as compared with last year's figures. In the remaining two districts,
viz , Gujranwala and Jhang, there was an actual decrease in the number of
primary vaccinations performed which may be attributed, though it should not
be so, to the commencement of vaccination work one month later than usual.
In regard to revaccination there was an increase in 17 and a decrease
in 11 districts, namely Amritsar (3,434), Gujranwala (3,168), Muzaffargarh
(2,858), Jhelum (1,464), Jhang (1,233), while in Ambala, Hoshiarpur, Feroze-
pore, Dera Ghazi Khan, Gujrat and Montgomery it varied between 72
and 810. The decrease may be attributed partly to the opposition of people
to revaccination and partly to the absence of small-pox in an epidemic form.
The increase in the district of Karnal was over 7,000, in Jullundur more than
5,000, in Kangra over 4,000 and in Rawalpindi and Rohtak more than 3,000.
In Hissar, Gurgaon, Simla, Ludhiana, Lahore, Gurdaspur, Sialkot, Shahpur,
Attock, Mianwali, Lyallpur and Multan the increase varied between 69 in Gur-
daspur and 1,553 in Hissar.
Total number of porsons vaccinated
by District Staff.—Statement No. I.
9. The number of persons vaccinated by the District Staff in the triennium
under report was 2,404,908 as against 2,588,886 in
the preceding period, showing a decrease of 183,978.
The reasons given for this decrease in paragraph 6 are applicable in this case
also.
District Staff—Percentage of suc-
cess.—Statement No. I.
10. The percentage of success in primary vaccinations performed by the
District Staff during 1916-17 was 95.22 as against
96.4 in 1915-16 and 97.15 in 1914-15, while in the
