Zhong Nanshan, a leading Chinese respiratory disease expert, told China Global Television Network (CGTN) that the current two percent death rate of the disease globally is not tolerated in China in spite of vaccination against COVID-19.
A relatively low-cost measure
Zhong said China had to adopt a zero-tolerance and zero-transmission policy, as the current Delta variant of COVID-19 spreads fast and replicates very quickly. While the policy is expensive, Zhong said the cost could be higher if ignored and the virus was allowed to spread. He also said that some countries had lifted restrictions while still reporting some small gatherings, leading to a new series of infections that come at a greater cost. Zhong said that the imported cases of COVID-19, or sporadic outbreaks will certainly be reported if China gradually opens to the world. Therefore, he thought the zero-tolerance policy would be taken for a long time. However, he further explained this is not a rigid zero-transmission policy. The policy duration depends on the basis of anti-virus performance worldwide. "No matter how well China does in containing the pandemic, the imported cases will not be avoidable when the country opens its doors. In my opinion, China's zero-tolerance strategy doesn't cost too much, [as it is a] relatively low-cost approach," he said.
Valuable experiences against COVID-19
As to his latest comments on recent sporadic outbreaks in some regions, he is confident on government help and experience gained before. A local outbreak of the COVID-19 in Guangzhou in May and June was controlled in about a month, while another outbreak reported in Nanjing, Jiangsu province, was tamped down within 26 days, said Zhong.
He highlighted four points on China's success in containing the recent sporadic outbreaks. "The first is to find the first patient and trace where he or she came from. The second is to figure out the infection chain," said Zhong, adding that the third is to find close contacts in the infection chain, so that they can be screened in a timely manner. The last point is that all the close contacts are isolated and tested in time to prevent the virus from spreading in local communities.
