While supply and demand issues surrounding N95 respirators are well-documented, until now the reasons for this discrepancy have been unclear. The logistical breakdown is rooted in federal failures over the past year to coordinate supply chains and provide hospitals with clear rules about how to manage their medical equipment. Internal government emails obtained by The Associated Press show there were deliberate decisions to withhold vital information about new mask manufacturers and availability. Exclusive trade data and interviews with manufacturers, hospital procurement officials and frontline medical workers reveal a communication breakdown — not an actual shortage — that is depriving doctors, nurses, paramedics and other people risking exposure to COVID-19 of first-rate protection.
