Diphtheria remains a significant threat in developing nations, with high mortality rates even in vaccinated individuals. Poor immunization coverage and limited access to antitoxin serum contribute to its resurgence.
Area of Science:
- Medical Microbiology
- Epidemiology
- Public Health
Background:
- Diphtheria, a historically significant childhood killer, is largely controlled in developed nations due to vaccination and improved healthcare.
- Developing countries bear the majority of the global diphtheria burden, indicating persistent public health challenges.
Purpose of the Study:
- To analyze mortality and morbidity trends of diphtheria over 12 years at a tertiary hospital.
- To evaluate the immunization status, microbiological confirmation, and antitoxin serum administration in diphtheria cases.
Main Methods:
- Retrospective analysis of 52 diphtheria cases over a 12-year period.
- Data collected on patient demographics, clinical presentation, treatment, and outcomes.
Main Results:
- Diphtheria incidence was higher in individuals over 5 years old (59.61%).
- A low percentage of cases (11.54%) were partially or fully immunized.
- The case fatality rate was alarmingly high at 36.53%.
Conclusions:
- The continued occurrence of diphtheria, even in immunized patients, suggests deficiencies in current immunization programs.
- Factors contributing to diphtheria's re-emergence include inadequate immunization coverage, limited availability of antitoxin serum, and antibiotic resistance.
