A blogger, indicating he was one of the two confirmed cases of novel coronavirus in Russia, revealed a full picture of his trips from Beijing to Tianjin on Feb 2 to help health authorities find those affected and curb the spread.

Russia reported its first two cases of coronavirus on Jan 31 and said the infected people were Chinese citizens who had been isolated.

According to Sputnik News, the Chinese man from Jiangxi province surnamed Wang, revealed on his blog written under the name "Russia startup entrepreneur Bin'ge" that he visited Beijing and Tianjin along with his Russian wife and 2-year-old daughter.

He said the family went to the National Museum of China in Beijing and took the train from Beijing to Tianjin on Jan 24.

"It was highly possible I was infected at the museum's elevator, because our family was warned some people from Wuhan, the epidemic center, had just used the elevator," he said.

He revealed the details of transport vehicles, hotels and shopping malls he used and visited, including a Riverside Plaza shopping mall in Tianjin.

Tianjin health authorities appreciated his efforts to reveal all details online, and publicized his trips on local media outlets to try to find those affected.

According to the Tianjin Health Commission, Tianjin has confirmed 69 cases, two recoveries and one death as of Wednesday morning.

The city announced it would make three more hospitals into designated facilities, adding a total of 18,500 rooms.

As of Tuesday, 1,226 people were under medical observation in Tianjin.
