Hubei, the Chinese province at the center of the novel coronavirus outbreak, announced 349 new cases today, the lowest daily number of infections officially recorded by China in weeks.

But the fall appears to be partly due to another change in how China counts a “confirmed case.” All official coronavirus cases from today must now be formally diagnosed before they are added to the totals.

The news of a fall in infections in China comes amid a spikes in cases in other Asian countries, including more than 20 members of a church congregation in South Korea.

Infections drop in virus epicenter: Confirmed cases in mainland China increased by 394, according to the country’s National Health Commission. Only 45 of those new cases were outside of Hubei, according to the NHC’s official figures.

The total number of confirmed cases in mainland China is now 74,576, bringing the global total to 75,674.

“Confirmed case” definition changes: The fall comes as the Chinese government said it would no longer count “clinically confirmed” cases among the official total infections. It was a reversal from a decision made a week ago to include patients who had tested negative for the virus but showed symptoms.

Death toll rises: The number of people killed by the virus continues to rise, with 114 more deaths announced in mainland China today. In total, the global death toll is now 2,128.

Diamond Princess deaths: Two passengers from the formerly quarantined Cruise Ship have died of the coronavirus, Japan’s health ministry announced today.

Both passengers were in their 80s and had been in hospital in Japan, but no further information is known about them at this stage. A total of 624 cases of the coronavirus have been found onboard the ship.

Passengers depart cruise ship: Large numbers of passengers who have tested negative for the virus are due to leave the Diamond Princess today after two weeks in quarantine on board. Cruise goers from Canada and Israel will be among those allowed off Thursday.

Japan’s health ministry has given up to 500 passengers permission to leave, a Princess Cruises spokesperson told CNN.

South Korea infections jump: There are now 82 cases of the deadly coronavirus in South Korea, the government reported today, after a jump of 31 additional cases overnight. Of the new cases, 23 went to the same church as a previously confirmed patient and health officials now plan to test the entire congregation for the virus.

Scientists slam conspiracy theories: A group of scientists from around the world have come together to denounce rumors that the coronavirus originated in a Chinese laboratory, rather than naturally in animals.

“(We) overwhelmingly conclude that this coronavirus originated in wildlife, as have so many other emerging pathogens,” 27 study authors said in a statement published Wednesday in medical journal The Lancet.
