Health authorities in Beijing's Daxing district said two people who had travelled to Wuhan were treated for pneumonia linked to the virus and are in stable condition.
In Guangdong, a 66-year-old Shenzhen man was quarantined on January 11 after contracting a fever and showing other symptoms following a trip to visit relatives in Wuhan, the provincial health commission said in a statement.
A total of 201 people have now been diagnosed with the virus in China. In Wuhan, 170 people are still being treated at hospital, including nine in critical condition, the city health commission said.

Chinese people travel across the country to visit family.
