Characteristics of Global Rapid Response Team Deployers and Deployment, United States, 2019-2022

The Centers for Disease Control and Prevention’s (CDC’s) Global Rapid Response Team (GRRT) was created in 2015 to efficiently deploy multidisciplinary CDC experts outside the United States for public health emergencies. The COVID-19 pandemic dramatically increased the need for domestic public health responders. This study aimed to follow up on previously published data to describe the GRRT surge staffing model during the height of the COVID-19 response. We conducted descriptive analyses to assess GRRT deployment characteristics during April 1, 2019–March 31, 2022, and characteristics of responders rostered in 2021 and 2022. We analyzed data on response events, remote versus in-person work, and international versus domestic deployment location. We also examined the number of responders on call per month, language proficiency, and technical skills. During the study period, 1725 deployments were registered, accounting for 82 058 person-days deployed. Of all person-days deployed during the study period, 82% were related to COVID-19. Eighty-seven percent of all person-days deployed were domestic. Virtual deployments that were not in person accounted for 51% of deployments registered, yet these resulted in 67% of person-days deployed. The median deployment duration was 31 days. We found a median of 79 surge responders on call each month. Among 608 responders rostered in 2021 and 2022, 35% self-reported proficiency in a second language. Epidemiology was the most common technical skill (38%). GRRT transitioned to primarily remote, domestic deployments to support the COVID-19 pandemic response. The GRRT model demonstrates how response structure shifted to address the global health threat of a pandemic.
