I agree that this is not cause for panic. It is cause for keeping a close eye on it and basic preparation because basic preparation is so easy with such little impact that it's a no brainer. An extra couple hundred bucks of food you'll eventually eat anyway and some n95 masks is so simple it's ridiculous not to.
Except n95 masks aren't going to do anything for you. You'd be much better off stocking up on Vitamin C - real Vitamin C.
