Chinese naval hospital ship Silk Road Ark on Wednesday set sail for the Xisha and Nansha islands to provide mobile medical services. It is the independently developed ship's first medical mission since going into service. With 14 clinical departments, including orthopedics, general surgery, dermatology and gastroenterology, the ship has the capacity for eight surgeries to be performed and over 300 patients to receive treatment onboard at the same time. During the mission, the ship will provide free diagnosis and treatment for military personnel and residents on the islands, and examine and repair local medical facilities.
