Chinese health officials said today that the death toll from the new coronavirus had passed 1,000. In Hong Kong, two people living on different floors of an apartment building were found to be infected, raising fears about how the virus can spread. Here are the latest updates and maps of where the virus has reached.

Quotable: “Let’s not shake hands in this special time,” said China’s leader, Xi Jinping, as he toured Beijing on Monday after facing criticism for his relatively low profile.

Another angle: During an Ebola outbreak in 2014, Donald Trump, then a private citizen, called for measures like canceling flights and forcing quarantines. Public health experts are now concerned that a president who has spoken openly about his phobia of germs might overreact to the coronavirus crisis.

Perspective: In an opinion piece for The Times, an epidemiologist discusses what is known, and not known, about the virus.
