A startling new report from Imperial College London warns that 2.2 million Americans and 510,000 Britons could die from coronavirus if extreme action isn't taken to change the course of the outbreak.

Why it matters: The report's dire warnings prompted a quick course correction from both the American and British governments on their strategies, but its strict recommendations and long timeline — 18 months — to stem the tide could have far-reaching implications for both populations and economies.

What they found: The report states the effectiveness of "mitigation," which includes isolating only the sick and those linked to them while advocating social distancing for at-risk groups, is limited. It instead recommends "suppression," a much more wide-ranging tactic to curb coronavirus' spread.

  • The researchers say that suppression "will minimally require a combination of social distancing of the entire population, home isolation of cases and household quarantine of their family members." It also recommends school closures.
  • The report notes that this strategy could have to be in place until a vaccine is developed, which could take 18 months — saying it is "the only viable strategy at the current time."

Worth noting: While China and South Korea have managed to suppress the outbreak using similarly draconian strategies, the report admits that it's not yet clear if suppression's successes can last in the long-term.

The state of play: The findings caused a messaging shift on both sides of the Atlantic.

The big picture: The New York Times reported that the Imperial College researchers "had shared their projections with the White House task force about a week ago and that an early copy of the report was sent over the weekend."

  • The BBC called the report the "crucial piece of evidence" that spurred Downing Street to act, saying the researchers "first realized the scale of the problem in China" and noting their "advice is heavily influential in government."

The bottom line: The report admits that "no public health intervention with such disruptive effects on society has been previously attempted for such a long duration of time."

  • "How populations and societies will respond remains unclear," it concludes.

Joe Biden is calling for the winner of November's presidential election to select Ruth Bader Ginsburg's replacement on the Supreme Court.

What he's saying: "[L]et me be clear: The voters should pick the president and the president should pick the justice for the Senate to consider," Biden said. "This was the position the Republican Senate took in 2016 when there were almost 10 months to go before the election. That's the position the United States Senate must take today, and the election's only 46 days off.
