I still to afraid to go on holliday due to the Covid-19 outbreak. Originally we made plans to go to Greece for 2 weeks, but I do not know what to do.
Shall I stay home and cancel my trip?
Yes you have to and never plan for any trips until this covid 19 gets cleared from this planet.
Due to economic recovery the flight services may get reopened in few weeks but it doesn't mean you can go anywhere you want unless you don't care about your life.
