Immunization status in paralytic poliomyelitis--a hospital based study.
Indian Pediatrics
|May 1, 1989
Summary
Most children with paralytic poliomyelitis were unvaccinated. This study highlights the critical importance of polio immunization in preventing the disease among children aged 8-14 years.
Area of Science:
- Pediatrics
- Epidemiology
- Immunology
Background:
- Poliomyelitis remains a significant public health concern, particularly in unvaccinated populations.
- Assessing immunization status is crucial for understanding disease incidence and prevention strategies.
Purpose of the Study:
- To analyze the immunization status of children diagnosed with paralytic poliomyelitis.
- To determine the correlation between polio immunization and the incidence of paralytic poliomyelitis in children aged 8-14 years.
Main Methods:
- Retrospective analysis of 646 paralytic poliomyelitis cases in children aged 8-14 years.
- Evaluation of immunization status (unimmunized, partially immunized, fully immunized) in 382 cases with known records.
Main Results:
- A high proportion (85.02%) of paralytic poliomyelitis cases occurred in unimmunized children.
- Only 8.9% of cases were in fully immunized children, indicating a significant difference in incidence.
- The difference in poliomyelitis incidence between vaccinated and unvaccinated groups was statistically significant (p < 0.001).
Conclusions:
- Polio vaccination is highly effective in preventing paralytic poliomyelitis among children.
- Low immunization rates correlate with a higher incidence of paralytic poliomyelitis.
- Public health initiatives should focus on improving polio vaccination coverage to reduce disease burden.
