Implementing the Shielding Approach to Prevent COVID-19 Infections in Humanitarian Settings
This document presents considerations from the perspective of the U.S. Centers for Disease Control & Prevention (CDC) for implementing the shielding approach in humanitarian settings as outlined in guidance documents focused on camps, displaced populations and low-resource settings.1,2 This approach has never been documented and has raised questions and concerns among humanitarian partners who support response activities in these settings. The purpose of this document is to highlight potential implementation challenges of the shielding approach from CDC’s perspective and guide thinking around implementation in the absence of empirical data. Considerations are based on current evidence known about the transmission and severity of coronavirus disease 2019 (COVID-19) and may need to be revised as more information becomes available. Please check the CDC website periodically for updates.
The shielding approach aims to reduce the number of severe COVID-19 cases by limiting contact between individuals at higher risk of developing severe disease (“high-risk”) and the general population (“low-risk”). High-risk individuals would be temporarily relocated to safe or “green zones” established at the household, neighborhood, camp/sector or community level depending on the context and setting.1,2 They would have minimal contact with family members and other low-risk residents.
