Nearly a year into the coronavirus pandemic, as thousands of patients are dying every day in the United States and widespread vaccination is still months away, doctors have precious few drugs to fight the virus.

A handful of therapies — remdesivir, monoclonal antibodies and the steroid dexamethasone — have improved the care of Covid patients, putting doctors in a better position than they were when the virus surged last spring. But these drugs are not cure-alls and they’re not for everyone, and efforts to repurpose other drugs, or discover new ones, have not had much success.

As Covid-19 took hold over the last year, hospitals and nursing homes used and reused scarce protective equipment — masks, gloves, gowns. This desperate frugality helped prevent the airborne transfer of the virus.

But it also appears to have helped spread a different set of germs — drug-resistant bacteria and fungi — that have used the chaos of the pandemic to grow opportunistically in health care settings around the globe.

These bacteria and fungi, like Covid-19, prey on older people, the infirm and those with compromised immune systems. They can cling tenaciously to clothing and medical equipment, which is why nursing homes and hospitals before the pandemic were increasingly focused on cleaning rooms and changing gowns to prevent their spread.

That emphasis all but slipped away amid an all-consuming focus on the coronavirus. In fact, experts warn, the changes in hygiene and other practices caused by the Covid-19 fight are likely to have contributed to the spread of these drug-resistant germs.
