Governments can implement these measures prior to travel, at points of entry, and after arrival. Restrictions or outright bans are subsequently one device among a broader array of choices. Terms similar to “travel bans” and “border closures” are subsequently misleading. They counsel that countries can somehow slam their borders closed, effectively shutting out public health dangers. In apply, however, hermetically sealing a rustic off on quick notice and for an extended time frame is nearly unimaginable. It can be hardly ever essential if states deploy efficient testing and quarantine measures.
