Latvia has a rigid policy towards foreigners since the outbreak of COVID-19. There has never been a social lock down in this country like in Germany, but the small Baltic country has been largely free of the virus since March 2020 through border closings and operating bans for the Riga airport and a temporary ban on cross-border traffic. The number of cases of COVID-19 has therefore so far been limited. For people entering Latvia, the rule is that no more than 16 cases per 100,000 inhabitants may be infected in the country of origin. Germany exceeded this threshold with 16.3 per 100,000 inhabitants last Friday.
