Objective:

To evaluate the epidemiological status of diphtheria outbreaks and clinical manifestations in Hajjah Governorate over a seven-year period from 2018 to 2024, addressing a critical knowledge gap.

Key Findings:
  • Significant increase in diphtheria cases in Yemen, with a 57% rise from 2022 to 2023, highlighting the urgent need for intervention.
  • Hajjah Governorate recorded 48 probable diphtheria cases, ranking fourth among northern governorates, indicating a regional health crisis.
  • Vaccination coverage in Yemen dropped to 42% in 2024, contributing to increased diphtheria incidence and underscoring the need for improved vaccination efforts.
Interpretation:

The study highlights a concerning rise in diphtheria cases in Hajjah Governorate, exacerbated by declining vaccination rates and ongoing conflicts that severely impact healthcare access.

Limitations:
  • Reliance on secondary data may limit the comprehensiveness of the findings, potentially affecting the reliability of the conclusions drawn.
  • Potential inaccuracies in clinical diagnoses due to varying healthcare facility capabilities may skew the reported incidence of diphtheria.
Conclusion:

The findings underscore the urgent need for improved vaccination efforts and public health strategies to combat diphtheria in resource-limited settings like Hajjah Governorate, where the health crisis is escalating.
