SUPPLY CHAIN: COVID-19 is exposing dangerous flaws in how we make and prescribe drugs. “Some 80 percent of the medically active ingredients in American drugs come from elsewhere. China, the country where COVID-19 originated and still the hardest-hit by the outbreak, is the world’s biggest supplier of pharmaceuticals. Lawmakers and public health officials have worried about this for a while—now, as the US plans for what may become a pandemic, it’s a bigger concern than ever. Patients who depend on medications are right to be thinking about potential shortages—and the fact that they may not even know about the shortages until they become severe.”
