Hospitals

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.

Growing up in the United States Virgin Islands, Dr. Marcella Nunez-Smith saw firsthand what can happen in a community with limited access to health care. Her father, Moleto “Bishop” Smith Sr., was only in his 40s when he suffered a debilitating stroke that left him partly paralyzed and with slurred speech.

The cause was high blood pressure, which could have been treated but had never been diagnosed. Without prompt access to advanced treatments, “the stroke was allowed to run its course,” Dr. Nunez-Smith, 45, recalled in a recent interview. Her father never fully recovered.
