China's efforts to prevent the new coronavirus pneumonia epidemic from flowing out of the country have been proven effective, a Chinese expert said Thursday.
So far, the number of confirmed cases reported overseas only accounts for less than 1 percent of the total number worldwide, said Wu Zunyou, an expert on epidemiology at the Chinese Center for Disease Control and Prevention, at a press conference held by the National Health Commission.
As of Wednesday, China had reported a total of 7,711 confirmed cases while the number of all cases reported outside the country stood at 68.
