23.  It is gratifying to observe that all the districts with the exception of
Vizagapatam, the Nilgiris, Chingleput and the Agency show considerable in-
crease in the total operations performed during the year as compared with the
previous year.

The districts which showed the largest increases were Guntūr (+28,443),
Tanjore (+23,134), Malabar (+ 22,461), Kistna (+ 20,022), Trichinopoly
( + 13,184), North Arcot ( + 11,806), Cuddapah ( + 11,666) and Salem (+10,553).

The slight fall in the district of Vizagapatam (—724) was attributed to the
diminished prevalence of smallpox and the consequent reduction in the number
under re-vaccination as also to the damaging effects of cyclone during the latter
part of last year which affected adversely the activities of the department. The
decrease in the Nilgiris ( — 41) where the District Health Scheme was not in force
is very small and almost negligible. In the case of Chingleput, the decrease
( — 2,724) was due to the long cessation of routine vaccination work for 4 months
against 2 months during the previous year and to the utilization of first-class
vaccinators for a time in the district for cholera work. The total number of
operations performed in the Agency areas was 66,271 against 75,311 during the
previous year, there being a decrease of 9,040 cases. This is explained by the fact
that in Vizagapatam Agency, where the decrease was 8,160 there was 4
months' cessation of routine vaccination work as against 2 months in the last
official year and in Gōdāvari Agency, which showed a fall (— 2,082) 2 posts of
vaccinators out of 3 were vacant during the year under report for 2 and 3
months, respectively.
