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.

For Covid-19 Vaccines, Some Are Too Rich — and Too Poor

CAPE TOWN — A few months from now, a factory in South Africa is expected to begin churning out a million doses of Covid-19 vaccine each day in the African country hardest-hit by the pandemic.

But those vials will probably be shipped to a distribution center in Europe and then rushed to Western countries that have pre-ordered them by the hundreds of millions. None have been set aside for South Africa.

The country, which will help manufacture the vaccine and whose citizens have enrolled in clinical trials, does not expect to see the first trickle of doses until around the middle of next year. By then, the United States, Britain and Canada may already have vaccinated more than 100 million people.

How Much Herd Immunity Is Enough?

At what point does a country achieve herd immunity? What portion of the population must acquire resistance to the coronavirus, either through infection or vaccination, in order for the disease to fade away and life to return to normal?

Since the start of the pandemic, the figure that many epidemiologists have offered has been 60 to 70 percent. That range is still cited by the World Health Organization and is often repeated during discussions of the future course of the disease.

Although it is impossible to know with certainty what the limit will be until we reach it and transmission stops, having a good estimate is important: It gives Americans a sense of when we can hope to breathe freely again.

Recently, a figure to whom millions of Americans look for guidance — Dr. Anthony S. Fauci, an adviser to both the Trump administration and the incoming Biden administration — has begun incrementally raising his herd-immunity estimate.
