Evaluation of pulse polio immunization in some districts of West Bengal & Assam.

A cross-sectional non-interventional survey was carried out in 5 districts of West Bengal and one district of Assam to find out the extent of coverage during IPPI. It was observed that in the recent rounds of IPPI, more than 95% coverage was observed in all the surveyed districts excepting in 24 Parganas South where coverage was around 92%. Situation at the Goalpara district further needed attention, as the coverage during February 03 as well as in the past two rounds were 90.13%, 88.13%, and 91.04% respectively. In all these districts booths were the main sites for IPPI dose though 1/3rd to 1/4th of the beneficiaries received immunization at home also. It was also observed that around 10% of the beneficiaries were not administered any PPI dose in the either of the rounds, in 24 Parganas (south) & Murshidabad districts, from where maximum number of Poliomyelitis cases were reported. At Goalpara it was 19%. Main reason for not being covered with PPI doses in either of the rounds in all the districts excepting Kolkata was "Not aware of the need for additional doses". In Kolkata "child sick" was the main reason. Health workers were main source of information of PPI in South 24 Parganas (67.13%), Malda (58.25%) & West Midnapur (54%). At Murshidabad "announcement through mike" (61.25%) was the main source of information while in Kolkata, TV was the main source (67.13%). Miking (56.38%) was the main source of information for PPI at Goalpara district of Assam. It was observed that involvement of multiple methods & media of communication was helpful in disseminating dates & other information of PPI.
