Early Determination of Case Fatality Rate of Covid-19 Pandemic During the Ongoing Yemeni Armed Conflict.

Objectives: To determine the case-fatality rate (CFR) of coronavirus disease 2019 (Covid-19) and its associated determinants in order to understand the true magnitude of the problem during the ongoing conflict in Yemen.

Methods: The CFR among the confirmed Covid-19 cases in Yemen was calculated. The data was retrieved from national Covid-19 surveillance between April 10, when the first COVID-19 case reported, and May 31, 2020.

Background: The need for early identification of coronavirus disease (COVID-19) cases in communities was high in Yemen during the first wave of the COVID-19 epidemic because most cases presenting to health facilities were severe. Early detection of cases would allow early interventions to interrupt the transmission chains. This study aimed to describe the implementation of community-based surveillance (CBS) in in internally displaced people (IDP) camps and urban settings in Yemen from 15 April 2020 to 30 September 2020.
