My family is visiting from Canada. They went to Disneyland here in CA on Wednesday, the day before the park announced closure due to precautions regarding coronavirus. They are now concerned that they may end up quarantined here, but we're making the best of it.
No sense worrying about what has not happened yet, and we're well set to weather whatever happens for the short term, at least.
Worry and fear - the least productive actions to take right now.
