To avoid panic buying like in singapore and hk, what supplies should we gradually stock up on now to be fully ready when covid-19 spreads in the us?

Our country wasn't: prepared. We needed ventilators, surgical masks, N95 respirators, gloves, testing kits, swabs, reagents, other personal protective equipment as well as disinfectants. People may wish to have acetaminophen, nasal saline for irrigation, decongetant, a month of prescription medication, adequate toilet paper (not hoards) and durable foods for at least 2 to 4 weeks.
