New study casts doubt on effectiveness of COVID-19 border closures
A new study comparing data from 166 countries that closed their borders during the first 22 weeks of the pandemic says most targeted closures – aimed at travellers from COVID-19 hotspots – did little to curb the crisis.
By contrast, total border closures barring all non-essential travel did slow the spread of COVID-19, but at such a high cost that the writers warn they should only be considered in the future as a last resort.
