Currently, on the Chinese mainland, the virus can only be found in hospitalized patients, people placed under medical observation and laboratories, Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said during an interview with China Central Television.
中国疾病预防控制中心流行病学首席专家吴尊友接受央视采访时表示：“中国境内存在新冠病毒的地方，主要是在隔离或住院的病人当中，和（相关的）实验室里。”

"It is now impossible to contract the virus in social environments, including schools and workplaces," he said. "There is no need to place extra restrictions on tourists out of concern for COVID-19 infections, though necessary travel safety precautions should be taken due to large gatherings."
他表示：“复学也好、复工复产也好，在社会层面是不可能感染新冠病毒的。从新冠肺炎防控角度来看，国庆节到各地去旅游应该没有什么特别限制和需要警惕的。由于国庆节人多，旅行安全还是要给予高度重视。”

After months of exploring and practicing strategies aimed at fending off imported infections, China has improved its knowledge in this aspect and is capable of gradually increasing incoming flights.
在防范输入病例方面，经过数月的探索和实践，我国已经提升了这方面的认知，也有能力逐步增加入境航班数量。

All incoming travelers will be managed in a closed-off loop and will not pose risks to local residents.
所有入境旅客都会进行闭环管理，不会为当地居民带来危险。
