Details released on city's new coronavirus case

The new COVID-19 case confirmed in Shanghai on Sunday is a 21-year-old university student surnamed Ren, health authorities in Shanghai and Qianjiang City, Hubei Province, revealed on Monday afternoon.

The Hubei native lives in Qianjiang and is a student at Zhongnan University of Economics and Law in Wuhan, the Qianjiang government said. 

He worked as an intern in Shanghai before January 21 and took a high-speed train to his uncle's home in Wuhan on January 21, the government said. 

Ren took his uncle's car to Qianjiang a day later. 

He took D354, a high-speed train to Shanghai, on May 14 to continue his internship and arrived at Shanghai Hongqiao Railway Station at 10:19pm, the government said.

He took Metro Line 2 to Maiju Hotel in the Pudong New Area that same night, the Shanghai Health Commission said during a press conference on Monday afternoon. 

He went voluntarily to the south branch of Shanghai East Hospital for coronavirus testing the following day. As his serological test was positive for coronavirus, he was quarantined for medical observation on the same day and started to develop symptoms during this period. 

The case was confirmed based on epidemiological study, clinical symptoms and the results of lab tests and medical imaging.

Ren said he wore a mask while riding the train and Metro and when he was outdoors in Shanghai, said Zheng Jin, a spokeswoman for the Shanghai Health Commission. 

"So far, 21 close contacts of the man in Shanghai have been tracked down and quarantined for medical observation," said Zheng. 

"Venues and public transport which the case has visited have been properly disinfected," said Zheng. 

Thirteen close contacts of Ren in Qianjiang have been tracked down and quarantined as well, and they are undergoing nucleic acid tests, local government said. 

Authorities are also investigating how Ren became infected, the government said.
