The Vatican City has turned out to be a big coronavirus hotspot. Reading elsewhere, there have been four cases in the Swiss Guard and three cases somewhere else. This means that the Vatican City scored 429.4 in today's update, so Denmark immediately proceeded to close the border.

Elsewhere in Europe, San Marino's status changes for the third time in three weeks. The country is now closed again with a rate of 36.2. Also closed are Bulgaria (33.6), Italy (39.9), Liechtenstein (40.3), Lithuania (31.4) and Poland (54.7). Only seven countries remain open.

Since last week, Sweden is assessed at county level. This time, Denmark closed the border for residents of Dalarnas län (36.3), Gotlands län (30.3), Jönköpings län (43.2) and Östergötlands län (38.2). 9 out of 21 counties remain open.

As usual, Denmark warns about high rates in some regions: Ida-Viru Maakond (375.2) and Vöru Maakond (57.5) in Estonia, Berlin (54.8) and Bremen (53.2) in Germany and Oslo (50.2) in Norway.
