While the SARS-CoV-2 virus was invisibly infecting people in 2020 through the air in hospitals, churches, workplaces and restaurants, people across the world were focused on disinfecting surfaces and washing their hands. Many governments and businesses installed plexiglass barriers that actually increased coronavirus spread, said Jose-Luis Jimenez, lead author of a new comprehensive historical assessment of major medical mistakes involving disease transmission, now published in the journal Indoor Air.

"History set us up for a poor response to the pandemic," said Jimenez, fellow at the Cooperative Institute for Research in Environmental Sciences (CIRES) and distinguished professor of chemistry at CU Boulder. "We might have had millions of fewer deaths, hundreds of millions fewer cases, if we'd taken appropriate, effective action from the start."
