COVID-19: Is herd immunity the only option for fragile Yemen?

Area of Science:

• Epidemiology
• Public Health
• Infectious Diseases

Background:

• Yemen faces a devastating conflict, destroying healthcare infrastructure and displacing millions.
• The COVID-19 pandemic presents a severe threat to Yemen's vulnerable population.
• Socioeconomic factors hinder the implementation of public health measures.

Purpose of the Study:

• To analyze the COVID-19 transmission dynamics in Yemen.
• To investigate the discrepancy between predicted and reported infection/mortality rates.
• To inform future public health strategies, including vaccine distribution.

Main Methods:

• Review of official COVID-19 case and mortality data.
• Analysis of factors influencing virus transmission in Yemen.
• Discussion of the potential for herd immunity.

Main Results:

• Official COVID-19 infection and mortality rates in Yemen are notably low.
• No confirmed excess mortality reports have been documented.
• The findings suggest a potential silent progression towards herd immunity.

Conclusions:

• Yemen's low reported COVID-19 figures may indicate widespread, undetected transmission.
• Seroprevalence studies are crucial for understanding the true trajectory of the pandemic in Yemen.
• Data from seroprevalence studies can guide effective resource allocation and vaccine strategies.
