2/5 In 2020, most countries switched from total to targeted #border closures followed by mandatory #quarantine and #screening of #travelers.
3/5 Evidence suggests: border closures may reduce the number of #COVID19 cases, disrupt disease spread across countries/between regions & slow #outbreak progression.
Early implementation, in combination with measures to reduce #transmission rates, likely enhances these effects.

4/5 #Quarantine of travelers may decrease📉 #COVID19 cases, but its effectiveness depends on #compliance & #enforcement and is more effective if followed by #testing.
Screening upon departure or arrival is unlikely to detect a large proportion of cases or to delay an outbreak.

5/5 When #CommunityTransmission is established, governments should consider coupling #border closure with other physical distancing policies.
When #reopening borders, strict measures including mandatory #quarantine of #travelers can help prevent further outbreaks 🛑
