With All Eyes on Covid-19, Drug-Resistant Infections Crept In

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.

Seeing the world as a one-pathogen world is really problematic,” said Dr. Susan S. Huang, an infectious disease specialist at the University of California at Irvine Medical School, noting that the nearly singular focus on the pandemic appears to have led to more spread of drug-resistant infection. “We have every reason to believe the problem has gotten worse.”

A few data points reinforce her fears, including isolated outbreaks of various drug-resistant infections in Florida, New Jersey and California, as well as in India, Italy, Peru and France. Overall figures have been hard to track because many nursing homes and hospitals simply stopped screening for the germs as resources were diverted to Covid-19. ...

Not all types of drug-resistant infections have risen. For instance, some research shows no particular change during the pandemic in the rate of hospital patients acquiring the bacterium Clostridioides difficile — a finding that suggests the overall long-term impact of the pandemic on these infections is not yet clear.

Dr. Huang and other experts said they are not suggesting that the priority on fighting Covid-19 was misplaced. Rather, they say that renewed attention must be paid to drug-resistant germs. Earlier research has shown that as many as 65 percent of residents of nursing homes carry some form of drug-resistant infection. ...
