As if Donald Trump’s irresponsibility was not already a national tragedy, the White House seems now to favor a controversial approach to Covid-19 that threatens to bring nothing less than mass suffering.

More than 216,000 Americans have already died. Yet on Tuesday, senior Trump administration officials said that they were receptive to pursuing “herd immunity,” an approach touted by a group of scientists who have put out what they call the “Great Barrington Declaration.” The idea is that the federal government should let the pandemic run its course until most of the population is infected and has ostensibly developed antibodies to ward off future infections. Typical estimates hold that 70% or more of the population would thereby become infected.

According to this idea, vulnerable groups would be targeted for “focused protection,” for example, introducing extra precautions such as frequent Covid-19 testing to avoid infections of the elderly living in nursing homes. The rest of the population “should immediately be allowed to resume life as normal,” according to the declaration.

This approach runs strongly against the overwhelming consensus of public health specialists, including Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases. The new Covid-19 approach would undoubtedly add massively to the suffering in the US in a very short period of time.

The idea that we should not try to control infections other than of vulnerable groups is based on a complete misunderstanding of the real choices facing the US — or facing any country for that matter. The core mistake is the belief that the only alternative to an economic shutdown is to let the virus spread widely in the population. Instead, a set of basic public health measures is enough, as many other countries have shown, to control the spread of the virus. The proper measures include widespread testing, contact tracing, isolating of infected individuals, wearing face masks, physical distancing, and barring super-spreader events (like Trump rallies). South Korea has exemplified this policy approach, as have many of its neighbors in the Asia-Pacific region.

Sadly, this very basic information seems not to have reached the White House or been understood by it, even though experts already knew in April that the Asia-Pacific region was suppressing the pandemic through these public health measures, and without the need for comprehensive lockdowns (or with only brief lockdowns to give time to scale up the public health measures). By suppressing the virus, these countries have limited the economic fallout.
