Outside of China, 225 cases have been reported, and a death in the Philippines. But the World Health Organization said that no new countries had reported cases.

Here are the latest updates.

Wuhan: A 34-year-old doctor who tried to raise the alert about the coronavirus has died of it. The authorities in the city, the epicenter of the outbreak, will begin rounding up the infected into mass quarantine camps. People are scrambling to muster help in Pittsburgh, Wuhan’s “sister city” of 40 years.

Quarantines: The number of coronavirus cases aboard a cruise ship quarantined off Japan doubled to 20. And Australian evacuees taken to Christmas Island, a former detention center for asylum seekers, were given sunscreen, sandals and video games, but some complained about conditions there.

Business impact: China took a step back from the trade war. Estee Lauder, Nintendo and Qualcomm joined the list of companies expecting damage from the coronavirus. But for face mask makers, business has never been brisker.
