Hi @Jennie8,
some hosts do deactivate their listing because they are moving to a new place (or other reasons), so no new guest can search for this listing, but still they have some confirmed bookings and do manage to host their "last" guests before moving out.
I moved to a new place End December 32 years ago and so I had my last guest mid december, after this the listing has been shut down and my new listing for the new place has been set up then in February...
However, in your case I would be a bit scared, but don't cancel yourself - contact airbnb and they will then help you to find an adequate lodging in the same area.
