As the outbreak of coronavirus intensifies, a question is on many people's minds: how long are we away from a cure or a vaccine? CGTN's Yang Chengxi spoke to coronavirus expert Rolf Hilgenfeld of Germany's University of Luebeck, who had been involved with China's fight against SARS in 2003.
"These RNA viruses are self-limiting. That means after a certain time, most people have developed antibodies against the virus, even though they did not fall sick. Then they are immune against the infection. These outbreaks typically end by themselves after a couple of months", said professor Hilgenfeld.
