There are 661 confirmed cases of coronavirus in eastern China's Zhejiang Province. That puts the province on top of a growing list of coronavirus cases outside of Hubei. And in the coastal city of Wenzhou alone, there are 265 confirmed cases. Authorities say that's likely because many students and workers in Wuhan returned there during the Lunar New Year holiday.

So authorities are restricting movement in the city in an effort to contain the outbreak. Wenzhou No. 6 People's Hospital cares for some of the patients. Some coronavirus patients develop severe pneumonia marked by extreme difficulty breathing. As of Sunday in Wenzhou, there were 16 such patients, about 6% of total confirmed cases.

For now, medical supplies in the city are considered adequate. Despite the hard work, many health officials here are hopeful.
