Innocent people who and symptom-free could be ripped away from their families and loved ones, put on lockdown, and lose their freedom. The CDC admits that the effectiveness of preventing infection using the shielding approach, a euphemism for strict, mass quarantines, has never been documented.
The CDC claims that the shielding approach is intended to alleviate stress on the healthcare system and to avoid long-term containment measures and lockdowns.
The shielding approach aims to reduce the number of severe COVID-19 cases by limiting contact between high-risk vulnerable people and the general population that is considered to be low risk. High-risk individuals would be temporarily relocated to safe "green zones" in households, neighborhoods, or camp/sector communities level. Those confined there would have minimal contact with family members and other low-risk residents. The CDC admits that grouping the elderly and people with underlying disease may result in rapid transmission of illness among the most vulnerable populations that the shielding approach claims it is trying to protect.
