Overview

This report analyzes the epidemiology and clinical characteristics of diphtheria in Yemen's Hajjah Governorate over a seven-year period. The findings highlight a significant increase in diphtheria cases, particularly among children, and underscore the urgent need for improved vaccination coverage and public health strategies.

Background

Diphtheria is a vaccine-preventable disease that poses a significant health risk, especially in regions with low vaccination rates. Yemen has experienced a resurgence of diphtheria cases, exacerbated by ongoing conflicts and a fragile healthcare system. Understanding the epidemiology of diphtheria in specific regions like Hajjah is crucial for developing effective prevention and treatment strategies.

Data Highlights

Key Findings

• Hajjah Governorate recorded 48 probable diphtheria cases from 2017 to 2020.
• Diphtheria cases in Yemen increased by 57% from 2022 to 2023.
• Vaccination coverage in Yemen dropped to 42% in 2024, contributing to increased disease rates.
• Children under 5 years are particularly vulnerable, with high mortality rates among unvaccinated individuals.
• The study fills a knowledge gap regarding diphtheria epidemiology in Hajjah, providing essential data for healthcare decision-makers.

Clinical Implications

Healthcare professionals should prioritize vaccination efforts in regions with low coverage to prevent diphtheria outbreaks. Additionally, awareness of the clinical manifestations and potential complications of diphtheria is essential for timely diagnosis and treatment.

Conclusion

The findings from Hajjah Governorate highlight the urgent need for enhanced public health interventions to combat the resurgence of diphtheria. Continued surveillance and vaccination efforts are critical to mitigate the impact of this preventable disease.
