COVID-19 has killed about as many Americans as the 1918-19 flu pandemic

U.S. DEATHS ARE RUNNING AT OVER 1,900 A DAY ON AVERAGE, THE HIGHEST LEVEL SINCE EARLY MARCH, AND THE COUNTRY’S OVERALL TOLL TOPPED 675,000 MONDAY.

COVID-19 has now killed about as many Americans as the 1918-19 Spanish flu pandemic did — approximat­ely 675,000.

The U.S. population a century ago was just onethird of what it is today, meaning the flu cut a much bigger, more lethal swath through the country. But the COVID-19 crisis is by any measure a colossal tragedy in its own right, especially given the incredible advances in scientific knowledge since then and the failure to take maximum advantage of the vaccines available this time.

“Big pockets of American society — and, worse, their leaders — have thrown this away,” medical historian

Dr. Howard Markel of the University of Michigan said of the opportunit­y to vaccinate everyone eligible by now.

Like the Spanish flu, the coronaviru­s might never entirely disappear. Instead, scientists hope it becomes a mild seasonal bug as human immunity strengthen­s through vaccinatio­n and repeated infection. That could take time.

“We hope it will be like getting a cold, but there’s no guarantee,” said Emory University biologist Rustom Antia, who suggests an optimistic scenario in which this could happen over a few years.

For now, the pandemic still has the United States and other parts of the world firmly in its jaws.

While the delta-fueled surge in infections might have peaked, U.S. deaths are running at over 1,900 a day on average, the highest level since early March, and the country’s overall toll topped 675,000 Monday, according to the count kept by Johns Hopkins University, though the real number is believed to be higher.

Winter might bring a new surge, with the University of Washington’s influentia­l model projecting an additional 100,000 or so Americans will die of COVID-19 by Jan. 1, which would bring the overall U.S. toll to 776,000.

The 1918-19 influenza pandemic killed 50 million people globally at a time when the world had onequarter the population it does now. Global deaths from COVID-19 now stand at more than 4.6 million.

The Spanish flu’s U.S. death toll is a rough guess, given the incomplete records of the era and the poor scientific understand­ing of what caused the illness. The 675,000 figure comes from the U.S. Centers for Disease Control and Prevention.

The ebbing of COVID-19 could happen if the virus that causes the disease progressiv­ely weakens as it mutates and more and more humans’ immune systems learn to attack it. Vaccinatio­n and surviving infection are the main ways the immune system improves. Breast-fed infants also gain some immunity from their mothers.

Under that optimistic scenario, schoolchil­dren would get mild illness that trains their immune systems. The same goes for today’s vaccinated teens: Their immune systems would get stronger through the shots and mild infections.

“We will all get infected,” Antia predicted. “What’s important is whether the infections are severe.”

Something similar happened with the H1N1 flu virus, the culprit in the 1918-19 pandemic. It encountere­d too many people who were immune, and it also eventually weakened through mutation. H1N1 still circulates today, but immunity acquired through infection and vaccinatio­n has triumphed.

Getting an annual flu shot now protects against H1N1 and several other strains of flu. Flu does kill between 12,000 and 61,000 Americans each year, but on average, it is a seasonal problem and a manageable one.

In many ways, the 191819 flu — which was wrongly named Spanish flu because it first received widespread news coverage in Spain — was worse.

Spread by the mobility of World War I, it killed young, healthy adults in vast numbers. No vaccine existed to slow it, and there were no antibiotic­s to treat secondary bacterial infections.

And, of course, the world was much smaller.

Yet jet travel and mass migrations threaten to increase the toll of the current pandemic. Much of the world is unvaccinat­ed. And the SARS-CoV-2 coronaviru­s, which causes COVID-19, has been full of surprises.

Markel said he is continuall­y astounded by the magnitude of the disruption the pandemic has brought to the planet.

“I was gobsmacked by the size of the quarantine­s” the Chinese government undertook initially, Markel said, “and I’ve since been gob-gob-gob-smacked to the nth degree.” The lagging pace of U.S. vaccinatio­ns is the latest source of his astonishme­nt.

Just under 64% of the

U.S. population has received as least one dose of a vaccine, with state rates ranging from a high of approximat­ely 77% in Vermont and Massachuse­tts to lows around 46% to 49% in Idaho, Wyoming, West Virginia and Mississipp­i.

Globally, about 43% of the population has received at least one dose, according to Our World in Data, with some African countries just beginning to give first shots.
