There's no point panicking. Food- already got osme stored for the fam and the government will probably still have to deliver food if things get that bad or riots will break out. Masks are not that neccesary, only in crowded areas as you correctly stated.
Above all else i keep contact minimal, especially with family members that work in hospitals and retail.
Also we shouldn't be afraid of plagues. It would suck to die this young before achieving my goals but dying from a plague would make me a martry of the highest status in jannah. I guess we should just take things easy and take precuation.
