A deadly new virus that originated in China and is popping up across the world is spurring some cities to cancel Lunar New Year events in an attempt to limit the risk of infection.

Officials in China announced Sunday that the coronavirus has killed at least 56 people and infected 1,975, an increase of 688 cases in 24 hours. China's health minister, Ma Xiaowei, said the country was entering a “crucial stage" as “it seems like the ability of the virus to spread is getting stronger."

Three cases have been confirmed so far in the United States.

The coronavirus — from a family of viruses that also caused the deadly SARS epidemic in 2002-03 -- has spread amid China's busiest travel period of the year, when millions crisscross the country or head abroad for the Lunar New Year holiday.

In France, Paris Mayor Anne Hidalgo said Sunday that Paris-based Chinese associations have canceled a Lunar New Year parade due to the epidemic.

“I have met with the Chinese community in Paris. They are very emotional and concerned, and they have decided to cancel the parade that was scheduled for this afternoon at Place de la Republique,” Hidalgo said on Europe 1 radio. “They are really not in a mood to party now."

France confirmed three cases of the virus Friday, the first in Europe.

On Saturday, the city of Bordeaux in the southwest part of the country canceled its planned Chinese New Year festivities in order to help contain the virus and as a gesture of support to those affected in China, Reuters reported.

Officials in China canceled Lunar New Year festivities across the mainland and scaled back celebrations in semi-autonomous Hong Kong.

On Saturday, many people stayed home with temples, major tourist sites and movie theaters all shuttered as authorities sought to limit the spread of the virus.

Beijing canceled all temple fairs, a popular tradition in northern China, with performances, games for children and booths selling snacks and New Year's-themed souvenirs, according to The Associated Press.

The Forbidden City in Beijing, Shanghai Disneyland, and a major safari park are among the tourist destinations that have closed indefinitely.

People in Wuhan, where the outbreak started, and more than a dozen nearby cities are unable to move about easily or leave town after authorities shut down buses, trains and planes and set up roadblocks to contain the virus.

“The atmosphere of Lunar New Year is not as good as last year even if there’s no coronavirus," May Wen told the AP. “Some shops closed down, and people aren't in the mood to go shopping.”
