Basel Fasnacht (the biggest and bestest carnival in Europe) has been cancelled for this year.
This morning (Friday 28th Feb) the Swiss Federal Health Minister has banned all events with more than 1,000 people present until further notice.
Basel Fasnacht has about 10,000 costumed participants, and 200,000 watching. It is the biggest event of the year ("drey scheenschte Dääg", "the three best days of the year", bigger than Christmas). This year it would have been next Monday (2nd to 4th March). This is very short notice, most of the preparations (crowd barriers etc.) are already in place and there are a lot of long faces around Basel today.
The last time it was cancelled was during World War 2.

On a different point, Easyjet is cancelling some flights, mostly to Italy, due to falling passenger numbers.
Yesterday BA report the same about flights to Milan.
