I think it's fine to remind her of DH's circumstance and ask her to be especially prudent about large gatherings, etc. Let her know that as this unfolds, the more extreme recommendations are going to apply to your family. (ie, I have no problem going on public transport right now, but you may ask her to stop sooner than the general public).
I think this is very good advice. Especially if you frame it in the context of your husbands health issues. I would remind her now to be extra vigilante with hand washing, etc. But as long as your kids are in school the germs are going around...
