What are the challenges ahead to combat the coronavirus?

The outbreak of coronavirus continue to spread rapidly. In the past couple of days, the daily new confirmed cases topped 100 in central China's Hubei Province. So what are the challenges lying ahead to combat the virus? CGTN spoke to Rolf Hilgenfeld, a coronavirus research expert and professor at the University of Lubeck in Germany. He and his team have found two SARS inhibitors, which are proteins that attack viruses and prevent them from maturing. Now he is in China, bringing these two inhibitors to help with the development of a vaccine for the new coronavirus.
