from https://www.cdc.gov/coronavirus/2019-ncov/global-covid-19/shielding-approach-humanitarian.html Table 1: Summary of the Shielding Approach1 Level / Movement & Interactions Household (HH) Level: A specific room/area designated for high-risk individuals who are physically isolated from other HH members. Movement: Low-risk HH members should not enter the green zone. If entry is necessary, it should be done only by healthy individuals after washing hands and using face coverings. Interactions should be at a safe distance (approx. 2 meters). Minimum movement of high-risk individuals outside the green zone. Low-risk HH members continue to follow social distancing and hygiene practices outside the house. 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. Movement: Same as above *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. Movement: One entry point is used for exchange of food, supplies, etc. A meeting area is used for residents and visitors to interact while practicing physical distancing (2 meters). No movement into or outside the green zone.
