Asking for status of faculty position search during coronavirus pandemic
It’s certainly appropriate to ask. Virus or not, the world will move on from this crisis, hopefully in a timeframe of a few months, you will still need a job, and the university will still need faculty to teach classes and do research. Students will still need to be educated. Higher education can be affected by economic recession, put probably less so than many other sectors of the economy. So don’t panic.

So yes, it’s fine to send them an email and politely inquire about the status of the search. Keep in mind that it’s possible they are scrambling to figure out how to keep instruction going and dealing with other urgent matters around the current crisis unrelated to faculty hiring. So the most likely response you’ll get is they are still figuring things out and don’t have any news.
