Impact of annual immunisation programme with oral polio vaccine on the prevalence of paralytic poliomyelitis.
Lameness survey was conducted in a rural community development block of Haryana in 1985. Enumerators contacted school teachers, anganwadi workers and several key informants in the community to identify lame children in 1-11 years age-group. Physician verified 219 lame cases to be due to poliomyelitis. Prevalence of poliomyelitis lameness was 7.3/1000 children born in 1974-76, 7.7/1000 children born in 1977-1980 and 2.3/1000 children born in 1981-1984 (expected to increase to 3.1/1000 when all children born in 1981-84 cross 5th year of life). Immunisation coverage with 3 doses of oral polio vaccine (OPV) was less than 10% during 1974-80 when immunisation was a clinic based activity. Coverage increased from 50 to 80% during 1981-85 when OPV was given in annual immunisation campaign. The results indicate that prevalence of paralytic poliomyelitis dropped at least by 60% after giving OPV in annual immunisation campaigns.
