We’re covering a warning in January from a top Trump administration official about the coronavirus, a move to the I.C.U. for Britain’s prime minister, and today’s voting in Wisconsin. | | By Chris Stanford | | Peter Navarro, President Trump's trade adviser, at a White House briefing on the coronavirus last month. Erin Schaff/The New York Times | | A memo by Peter Navarro, President Trump’s trade adviser, warned in late January that failing to contain a coronavirus outbreak could cost the U.S. trillions of dollars and put millions of Americans at risk of illness or death. | | “The lack of immune protection or an existing cure or vaccine would leave Americans defenseless in the case of a full-blown coronavirus outbreak on U.S. soil,” Mr. Navarro’s memo stated. | | The memo, dated Jan. 29, was the highest-level alert known to have circulated in the West Wing. It came as the administration was taking its first substantive steps to confront the crisis but during a period in which the president was also playing down the risks. | | ■ Prime Minister Boris Johnson of Britain spent the night in intensive care after his condition worsened, almost two weeks after testing positive for the virus. His foreign secretary, Dominic Raab, is temporarily in charge of the government. | | ■ Wisconsin will hold its presidential primary today, the first test in what’s expected to be a fight over the changing of voting rules during the pandemic. The state’s Supreme Court on Monday rejected the Democratic governor’s attempt to postpone in-person voting, and the U.S. Supreme Court ruled against an attempt by Wisconsin Democrats to extend the deadline for absentee voting. | | ■ The acting Navy secretary, Thomas Modly, addressed sailors aboard the aircraft carrier Theodore Roosevelt and criticized them for cheering their captain, who was removed after he requested help amid an outbreak on the ship. | | ■ Prime Minister Jacinda Ardern offered reassurances to the children of New Zealand, announcing that the Easter bunny and the tooth fairy had been designated essential workers. She cautioned that, because of distancing rules, “the Easter bunny might not make it everywhere this year.” | | In Queens on Monday, the second day in a row in which fewer than 600 virus-related deaths were reported in New York State. Juan Arredondo for The New York Times | | The country’s first 5,000 deaths from the coronavirus occurred in just over a month. The second 5,000 came in less than five days. Our map shows how quickly the numbers have risen. | | The New York metro area accounts for more than 40 percent of U.S. deaths, although Gov. Andrew Cuomo offered some promising news on Monday, saying that death and hospitalization rates in the state had started to stabilize. He again cautioned New Yorkers to maintain distancing measures. | | The details: When will New York City reach the peak of the outbreak? Public health officials say it may be soon, or it may be a month away. Here’s what we know. | | 1. Hospitals must be able to safely treat all patients requiring hospitalization, without resorting to crisis standards of care. That means having adequate beds, ventilators and staff. | | 2. The authorities must be able to test everyone who has symptoms, and to get reliable results quickly. That would be well more than 750,000 tests a week in the U.S. | | 3. Health agencies must be able to monitor confirmed cases, trace contacts of the infected, and have at-risk people go into isolation or quarantine. | | 4. There must be a sustained reduction in cases for at least 14 days, because it can take that long for symptoms to appear. | | Minneapolis, for example, acted quickly, and had a considerably lower mortality rate than St. Paul, just across the Mississippi River. It appears that the economy in Minneapolis emerged stronger, too. | | The new study, by researchers at the Federal Reserve and M.I.T., comes amid a debate over the health benefits and economic costs of distancing. | | PAID POST: A Message From XBrand | Renewable Energy in Today's Age | Look around you...All of the things that you love about this planet can be used to power it. the sun, rain, wind, tides and waves.

It has been running ever since, managed in shifts among newsrooms in Hong Kong and London and the headquarters in New York. | | “It’s the longest-running live thing The Times has ever done,” said Rebecca Blumenstein, a deputy managing editor. “We’ve never done anything of this scale before.” | | Editors and reporters from nearly every desk have volunteered to help lighten that workload. Others were drafted to serve on the digital front lines. | | Michael Cooper, who normally covers classical music and dance, has been working on the briefing, which requires him to swiftly process and report on a deluge of information. | | “It’s like drinking from a fire hose,” Mr. Cooper said. And on top of the constantly shifting story lines, Times employees have mostly been working from home since March 13. | | “We’re pretty used to improvising,” Mr. Cooper said. “When I used to cover plane crashes, you would make a little bureau on a folding table at some disaster site and work from there. We’re used to doing things from strange places.” | | That’s it for this briefing. See you next time. | | Thank you Melissa Clark provided the recipe, and Theodore Kim and Jahaan Singh provided the rest of the break from the news. John Otis wrote today’s Back Story.
