China's Top Medical Advisor Warns The Country May Now Face a Second Wave of COVID-19

'The majority of... Chinese at the moment are still susceptible of the COVID-19 infection, because (of) a lack of immunity,' Zhong Nanshan, the public face of government's response to the pandemic, told CNN. 'We are facing (a) big challenge,' Zhong added. 'It's not better than the foreign countries I think at the moment.' Zhong, who helped expose the scale of the 2003 outbreak of Severe Acute Respiratory Syndrome (SARS), also said authorities in ground-zero Wuhan had under-reported cases during the early days of the pandemic. 'The local authorities, they didn't like to tell the truth at that time,' said Zhong, who was part of a team of experts sent to Wuhan to investigate the outbreak.
