First European 'travel bubble' breaks down

The  European continent's first pandemic "travel bubble,'' created in May by Estonia, Latvia and Lithuania, was burst today, as Latvia said it was mandating a 14-day quarantine on everyone arriving from Estonia, Sky News reports.

Estonia has had 21 infections per 100,000 population over the previous two weeks, according to European Centre for Disease Prevention and Control, passing the 16 threshold set by Latvia for mandatory quarantine.
