Central Chinese city of Wuhan on Wednesday started screening its key roadways in an all-out effort to curb the spread of a contagious pneumonia that has killed 17 people.

All vehicles and people that intend to move in or out of the city by road are subject to the screening procedures to control the epidemic. 

The outbound travelers are required to go through a body temperature test. If found with fever, travelers will be transferred to designated clinics for further medical checks.  

Animals are also the target of scrutiny. The city has banned the transportation and sale of wild animals. The pneumonia, a result of a new type of coronavirus, was started from a local seafood market which also sold wild animals. 

Respiratory system specialists warn the coronavirus can be transmitted between people and is able to mutate. Wuhan Mayor Zhou Xianwang has appealed people to reduce traveling in and out of the city to curb the spread of the disease.
