<unk> , in public health, is social distancing measures taken to protect a small, defined, and still-healthy population from outsiders during an epidemic (or pandemic) before the infection reaches that population. It is sometimes referred to as "reverse cordon sanitaire." Due to the disruption that<unk>  can cause, it is typically considered only under exceptional circumstances where implementation and enforcement are feasible. It is more easily achieved in circumstances where voluntary compliance of the sequestered population is likely.
