Wuhan, the center of China’s Covid-19 outbreak earlier this year, said it tested almost seven million people over 12 days after new infections prompted fears of a second wave. But while Beijing worries about a recurrence, it has another problem. Its move to impose authoritarian security rules on Hong Kong has not only earned it global condemnation, but provided the White House with another reason to pounce as it intensifies its strategy of blaming China for the pandemic. President Donald Trump, who went golfing this past Memorial Day weekend, and his administration have been blamed for exacerbating infection rates through months of mistakes, delays and false statements. America’s death toll now stands at almost 100,000, the most in the world. —David E. Rovella

Most doctors and nurses who got mild forms of Covid-19 produced antibodies that could prevent reinfection, according to a study conducted on hospital staff in northeastern France. Gauging the ability of antibodies to stave off the pathogen is a critical issue in global efforts to rein in the disease, which has killed almost 350,000 people worldwide and infected 5.5 million. More than 2.2 million have recovered. 

Cooped-up Americans desperate to get out are dreaming of doing something—anything—that resembles a vacation. But most worry a second wave of Covid-19 is coming, and think politicians have pushed too fast to reopen. That’s where the “Covid camper” comes in.

A nuclear fusion startup raised an additional $84 million to enter a new phase of research. Fusion, the process that powers stars, doesn’t have the dangerous drawbacks of fission, which powers existing nuclear plants. Harnessing fusion and making it work has long been seen as a key to slowing global warming.

As states reopen faster than medical experts have said is wise, air travel over the Memorial Day holiday weekend returned to levels not seen since March, when stay-home orders first took effect.

In America, you are either a Democrat or you are an authoritarian, Frances Wilkinson writes in Bloomberg Opinion, explaining that today’s Republican Party reflects the realities of regimes in Russia or Hungary. Ramesh Ponnoru writes, however, that the Democratic Party is now the party of the upper middle class, and will have a hard time reclaiming the working class.

What’s Joe Weisenthal thinking about? The Bloomberg news director contends the biggest macro question going forward may be whether the shock caused by the pandemic is enough to meaningfully change domestic policies around the world. Will Germany give up its obsession with balanced budgets? Will China build a stronger domestic safety net? Will the U.S. spend more aggressively on lowering unemployment? The possibilities, Joe argues, seem more realistic these days.
