Is it safe to travel to Venice in April with the corona flu virus?

No, it's not by any means sorted there yet. They need at least another month.

Well as of today the question has been answered for you......

I would not travel at this time or any time in the near future until the virus is under control.

The problem is not just going to a country which has known victims of the virus, the bigger problem is being in airports and air planes where people travel from ALL over the world...who could be infected and spread the virus to you...to take home to everyone else in your life.

So, you see, this virus is not just about avoiding a certain location, everyone should just stay put to prevent spreading the virus.  This virus is not worth dying for. There are people who do not even know they are already infected and spreading the virus.

You'd be wise not to (and it's Coronavirus) at the moment, but who knows what the situation will be by early April!!

Don't count on it, It will get worse before it gets better.

Probably not. You'll have to wait and see though.

i dont see why it wouldnt be

Unlikely to be clear as soon as April.
