the vaccination of a whole block of refractory villages. Throughout the triennium
the Newgong district vaccination work under Dr. Dodds Price has continued to be
a model for other districts where the administration has been less close, and the low-
smallpox mortality ratio of this district has been well maintained. There is a drop of
5,859 operations in the district of Sibsagar which is stated by the Civil Surgeon Major
Macdonald, I.M.S., to be largely due to the non receipt from tea estates of returns
regarding the number of operations performed on them. One notes however
that the average number of operations per vaccinator during 1919-20 was only 609,
as compared with 1,008 in 1915-16 and 915 in 1916-17, a decrease which is
probably not unconnected with the fact that the Civil Surgeon did not inspect any
vaccination operations during the season 1919-20, although in part due to the
influenza epidemic of 1918-19. The low primary success rate of 86.79 per cent.
in the Lushai Hills where the dispensary success rate was 96.86 per cent. seems to
indicate that lymph is kept too long by the vaccinators before use. Probably this is
more or less inevitable under hill conditions, but the Civil Surgeon is being asked to
revise the arrangements for distributing lymph. It seems that in the district of
Lakhimpur the extra vaccinators who were engaged on my recommendations have
been employed to very good purpose, as in spite of the influenza epidemic Lakhimpur
shares with Sylhet the credit of having performed more vaccination operations during
this triennium than in the previous one, the actual gain being 9,238.
