Immunization status in paralytic poliomyelitis--a hospital based study.

Six hundred and forty six cases in the age group 8-14 years suffering from paralytic poliomyelitis were analysed to find out the immunization status and its correlation with the incidence of poliomyelitis. In 382 cases where the immunization status was known, it was found that 325 (85.02%) cases were not immunized, 23 (6.02%) cases were partially immunized, while only 34 (8.9%) cases were fully immunized. The difference in the incidence of poliomyelitis between the vaccinated and non-vaccinated categories was found to be significant (p less than 0.001).
