Epidemiology of poliomyelitis in a slum of Bombay.

A disease prevalence and immunization coverage survey in a typical slum in Bombay in the year 1988 revealed 93 children with residual poliomyelitis amongst 14,439 children below 9 years of age, indicating high (33.0/100,000 population) annual incidence of poliomyelitis. Only 62 (66.6%) of these 93 lame children sought admission in hospital during the acute phase of illness. The high incidence was attributed to a low immunization (OPV) coverage level in the most vulnerable age group. The immunization coverage for 3 doses of oral polio vaccine below 2 years of age was 43.5%. A large number of children were not commencing their immunization schedule at the right age. The survey indicated a poor "community participation" in the immunization programmes due to a poor "health awareness".
