Carnival festivities should not go ahead "as normal" this winter, the premier of Germany's most-populous state of North Rhine-Westphalia said. Carnival traditions often involve large parades and parties, kicking off in November and culminating in a long weekend in February each year.

"In this year of coronavirus we all need to give up certain things we hold dear," Armin Laschet told German newspaper Bild am Sonntag. He said he was in discussion with carnival societies about alternatives.

The government said 292 new cases were reported within the past 24 hours — making it the highest daily increase since the pandemic began. Compared to its neighbors and other hard-hit countries around the world, Hungary has had a low infection rate. Experts have attributed the recent rise in cases with more lax attitudes to social distancing measures — particularly among the younger generation — as well as increased testing.
