China did not just stop selling masks — it also bought up much of the rest of the world’s supply. According to official data, China imported 56 million respirators and masks in the first week after the January lockdown of the city of Wuhan, where the coronavirus emerged.
On Jan. 30, the last day for which data is available, China managed to import 20 million respirators and surgical masks in just 24 hours. Through February, civic-minded entrepreneurs and aid groups visited pharmacies in affluent countries and emerging markets alike, buying masks in bulk to send to China.
Global companies and charities donated, too. Honeywell provided 500,000 N95 respirator masks, and 3M donated a million of them. Honeywell said its contribution came from stockpiles in China, while 3M declined to identify the source of its donations.
3M also donated a second shipment of respirators, but declined to say how many that included. The charitable foundation of Bristol Myers Squibb funded an additional 220,000 N95 respirators for doctors and nurses at the center of the outbreak.
