Just think this might be a bit niche for the coronavirus forum and might be useful for discussion as things develop.
We have just had a new AP start a week ago - I feel rather bad for her as her entire planned stay is going to be in the midst of this crisis. I guess it's possible if they look at shutting down flights she may decide to go home early if she can and obviously she can do that if she wants. Friends have already lost an AP who has gone home so she can apply for college and stuff before flights get stopped.
New AP is a lovely, warm and quite mature girl from Spain - good with kids (and our cat loves her!), and she already has a friend working locally, fortunately. She doesn't seem too phased by things thus far.
If schools shut and we are all WFH, luckily DD is now at secondary school so doesn't need much attention, but I guess I would ask AP to do her hours in the middle of the day to support DS (8) in doing some work, as school has said they will set tasks remotely if it comes to it.
How are things looking with your APs?
