Since the start of the prevention and control of pneumonia caused by the novel coronavirus, Hainan and Guangdong have both moved the prevention and control threshold forward. Hainan has sent more than 160 joint anti-epidemic personnel from multiple departments to Zhanjiang of Guangdong Province, and set up four prevention and control points and an observation point there. In addition, Hainan has taken various measures to prevent and control the epidemic on ferries crossing the sea, such as pre-boarding temperature measuring, vessel disinfection and setting up isolation rooms.
