Objective   To summarize the status of emergency response-related professional/technical personnel deployment and replenishment and capacity building requirement in municipal and district disease prevention and control institutions of Beijing during coronavirus disease 2019 (COVID-19) epidemic for providing evidences to the management of human resource for epidemic control in the institutions.

  Methods  Using cluster and convenient sampling, we conducted an online survey among 1 127 professionals in one municipal center and 4 district centers for disease control and prevention (CDC) in Beijing with a self-designed questionnaire during April – May, 2021. Absolute quantity, constituent ratio, and Fisher′s exact test were adopted in statistical analyses with Microsoft Excel 2010 and SPSS 22.0 software.
