A Novel Way to Combat Covid-19 in Nursing Homes: Strike Teams

HENDERSONVILLE, N.C. — The coronavirus entered Cherry Springs Village quietly, then struck with force. Nearly every staff member and resident of the long-term care facility would become infected.

They needed help — fast — and the county responded: It sent in a “strike team” of medical workers, emergency responders, clergy and others, in what is becoming a new model for combating Covid-19 in residential care centers.

Nurses and doctors from hours away came to aid sick residents and replace staff who had contracted the virus. They set up oxygen and IV drips, to avoid sending residents with milder illness to overburdened hospitals.

Covid-19: Blood Plasma Authorization Is Put on Hold

Last week, just as the Food and Drug Administration was preparing to issue an emergency authorization for blood plasma as a Covid-19 treatment, a group of top federal health officials including Dr. Anthony S. Fauci intervened, arguing that emerging data on the treatment was too weak, according to two senior administration officials.

The authorization is on hold for now as more data is reviewed, according to H. Clifford Lane, the clinical director at the National Institute of Allergy and Infectious Diseases. An emergency approval could still be issued in the near future, he said.

What if ‘Herd Immunity’ Is Closer Than Scientists Thought?

To achieve so-called herd immunity — the point at which the virus can no longer spread widely because there are not enough vulnerable humans — scientists have suggested that perhaps 70 percent of a given population must be immune, through vaccination or because they survived the infection.

Now some researchers are wrestling with a hopeful possibility. In interviews with The New York Times, more than a dozen scientists said that the threshold is likely to be much lower: just 50 percent, perhaps even less. If that’s true, then it may be possible to turn back the coronavirus more quickly than once thought.

The new estimates result from complicated statistical modeling of the pandemic, and the models have all taken divergent approaches, yielding inconsistent estimates. It is not certain that any community in the world has enough residents now immune to the virus to resist a second wave.
