As deaths from the coronavirus topped 1,000 — nearly all of them in China — Beijing on Tuesday urged countries that have enacted travel restrictions aimed at curbing the outbreak to restore normal ties for the sake of the global economy. The appeal from China's Ministry of Foreign Affairs underscored the economic dangers posed by the unprecedented shutdown of much of the world's second-largest economy, as well as the ruling Communist Party's concerns about the outbreak's capacity to fuel domestic instability.

Authorities in the virus-hit city of Wuhan have announced fresh restrictions on residents, making millions of people virtual prisoners in their own homes. Two provincial health bosses have been fired as the Communist Party struggles to contain widespread anger over the spread of the virus. Here’s what we know:

● The death toll from the coronavirus surged again, with 97 deaths on Tuesday. The number of confirmed infections continues to rise, but the rate of growth is slowing.

● American Airlines announced that it will suspend flights to China and Hong Kong through the end of April, a month longer than the carrier had previously planned. The State Department is allowing non-emergency U.S. personnel to leave Hong Kong of their own accord.

● Authorities in Wuhan tightened restrictions on citizens, allowing just one member of a household to make one shopping trip every three days and placing entire buildings under quarantine.

Thirty-nine more people on board the Diamond Princess cruise ship have been diagnosed with the virus, bringing the total number of infections to 174. Around 3,600 people are being held in quarantine on the ship off the coast of Japan, and crew members say they aren’t being adequately protected as more workers fall ill.

● China is bracing for the return of some 160 million migrant workers to their cities of employment as the country’s economy sputters back to life after an extended holiday following the outbreak.
