District Staff.—
Statement No. I.
8. The total number of operations performed by the district staff in
1915-16 was 796,572 as against 782,988 in the previous year, an increase of
13,584. Compared with the previous year there was a decrease of 8,251
primary operations and an increase of 21,835 re-vaccinations In the case of
primary operations 13 districts recorded an excess and 15 a decrease as com-
pared with the figures for the previous year. The diminution is partly due to
the fact that from all those districts which showed a reduction of more than one
thousand except Montgomery vaccinators were sent for training to the Punjab
Vaccine Institute at Lahore and they were replaced by vaccinators from the
Special Staff, Punjab, whose work is shown separately, and partly to the decrease
in the number of children. The decrease in the Montgomery District is not
satisfactorily explained by the Civil Surgeon, but is probably due also to the
diminution in the number of births in that district. The percentage of suc-
cessful primary vaccination of children under one year of age to the total
number available was 73.41, the same as in the previous year, and 72 98,
the average for the previous five years. This satisfactory result is an indication
of the good work of the district vaccination staff The increase of 21,835
re-vaccinations compared with the figures for the previous year is very
satisfactory. This increase was noticed in 19 districts, and was well marked
(5,686) in Karnal, (4,526) in Ambala. (4,093) in Gujranwala, (3,053) in
Rothak, (2,366) in Muzaffargarh, (2,297) in Amritsar and (2,008) in Hissar
districts; in all others it varied between 1,491 in Ludhiana and 5 in
Shahpur. The decrease in the 9 districts of Kangra, Rawalpindi, Jullundur,
Multan, Attock, Sialkot, Gurdaspur, Dera Ghazi Khan and Simla is principally
due to the difference in the population of the areas selected for re-vaccination.
The percentage of males and females to total number of re-vaccinations
was nearly the same as last year, viz , 68.77 in the case of males and 31.23 in
that of females as against 68.55 and 31.45 in 1914-15. The percentage of
success in primary vaccination was 96.45 as against 97.15 in the previous
year, while in the case of re-vaccination it was 73.38 as compared with
70 78 in the previous year. The slight decrease in the percentage of success
in primary cases is due to the fact that vaccine lymph supplied from the
Murree Depôt early in the season did not produce as good results as it should
owing to the excessive heat in certain districts in the plains. The percentage
of vaccinations in which results were not known to the total number in 1915-16
was 4.85 in the case of primary and 18.20 in that of re-vaccination as compared
with 4.34 and 18.48, respectively, in the year preceding.

Special Staff.—State-
ment No I and its
appendix.
10 The vaccinators of the Special Staff, Punjab, performed 28,733
primary operations and 18,270 re-vaccinations during the year as compared with
23,328 and 23,738 in the year preceding. This shows an increase of 5,405 or
over 23 per cent. in the number of primary vaccinations and a diminution
of 5,468 or 23 per cent. in re-vaccinations as compared with the figures for the
year preceding. The percentage of success was 97.36 in the case of primary
operations and 72.67 in that of re-vaccination as against 96.25 and 70.16, res-
pectively, in 1914-15.
Cantonment staff.
Annual Form No. I
and its appendix.
11. The work done in cantonments which entertain their own vaccina-
tors, amounted to 4,459 primary vaccinations and 4,443 re-vaccinations, an
increase of 684 in the case of the former and of 3,125 in the latter over the
corresponding figures for last year. The largest number of persons vaccinated
was 3,680 in Ambala, 2,369 in Lahore, 890 in Rawalpindi and 813 in Feroze-
pore cantonments.
The percentage of success was 98.48 in primary and 70.33 in re-vaccina-
tion as against 99.08 and 70.04 in the previous year and the ratio per cent. of
unknown cases to total cases in the case of primary was 2.69 and re-vaccination
9.88 as compared with 1.64 and 4.02 in 1914-15.
