All travellers wherever they are from are welcome in my home. @Erwin111
I know those who are at high levels of risk are restricted in their travel. I also know that there is a pandemic and that it has now spread worldwide in countries including US, Canada and in Europe.
I don't want to discriminate based on where someone is from so will accept all.
I am following WHO guidance such as always using antiseptic gel and using tissues.
Host need to decide on an individual basis how they want to handle things. If you have health concerns, that make you uncomfortable with accepting bookings, then snooze your listing. You can talk to Airbnb about cancelling visitors but if the cancellation doesn't fall within their EC policy for the virus you will incur penalties.
