Burned by COVID supply crunch, hospitals invest in U.S. mask-making

Two days before Christmas, a cargo ship left Mumbai with a mask-making machine bound for Illinois-based OSF HealthCare, which will use the equipment to make its own N95 masks. It isn't the hospital group's first foray into manufacturing. After COVID-19 border closures in early 2020 choked shipments from Asia, producer of about 80% of the world's medical masks and protective gear, OSF and some other hospital groups started investing in U.S. production of key supplies including masks, gowns and critical pharmaceuticals.
