“July 26, 2020 ... This document presents considerations from the perspective of the U.S. Centers for Disease Control & Prevention (CDC) for implementing the shielding approach ... focused on camps, displaced populations and low-resource settings ... 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. They would have minimal contact with family members and other low-risk residents ... physically separating high-risk individuals from the general population ... implementation of the approach necessitates strict adherence to protocol ... Household (HH) Level: A specific room/area designated for high-risk individuals who are physically isolated from other HH members ... Low-risk HH members should not enter the green zone ... Neighborhood Level: A designated shelter/group of shelters (max 5-10 households), within a small camp or area where high-risk members are grouped together. Neighbors ‘swap’ households to accommodate high-risk individuals ... Camp/Sector Level: A group of shelters such as schools, community buildings within a camp/sector (max 50 high-risk individuals per single green zone) where high-risk individuals are physically isolated together ... One entry point ... No movement into or outside the green zone ... Dedicated staff need to be identified to monitor each green zone. Monitoring includes both adherence to protocols and potential adverse effects or outcomes due to isolation and stigma. It may be necessary to assign someone within the green zone, if feasible, to minimize movement in/out of green zones ... Plan for an extended duration of implementation time, at least 6 months ... green zones be maintained until one of the following circumstances arises: (i) sufficient hospitalization capacity ... effective vaccine or therapeutic ... COVID-19 epidemic affecting the population subsides ... contingency plans to account for a possibly extended operational timeline are critical ... Separating families and disrupting and deconstructing multigenerational households may have long-term negative consequences ... Households participating in house swaps or sector-wide cohorting are at particular risk ... Plan for potential disruption of social networks ... Failure to do so could lead to both interpersonal and communal violence ... While the shielding approach is not meant to be coercive, it may appear forced or be misunderstood”
