@Chrissy73 If it were me, yes, I would hold off. Read all the threads here if you haven't already about guests cancelling left and right and hosts' calendars ending up virtually empty for the next month or two. It wouldn't be a great start to your hosting career to have to be dealing with Airbnb cancellations, trying to reach them on the phone when they are totally swamped with calls, having guests book and then cancel, sending you barrages of messages as to whether they will get refunded in full, etc.
And true, you don't want to waste that search ranking boost that is given to new listings. I'd wait awhile and see how this all shakes down- presently the virus is spreading, not abating.
