A survey was conducted in all the schools of one rural administrative block (population 96,234) in south India. Among the 18,548 children enrolled in schools, physical handicaps were prevalent at a rate of 6.58/1,000. Residual paralysis due to poliomyelitis was the commonest handicap, accounting for 48 percent, for a prevalence rate of 3.2/1,000. The prevalence rates were approximately the same in primary, middle and high schools, thereby indicating that the annual incidence of poliomyelitis had no major changes during 1962 to 1974, the years of birth of the present school-going children. The rate of prevalence of polio in Vellore town is also 3.2/1,000 school children: thus the disease is as common in villages as in Vellore town.
