吴尊友最新发声！
1月8日起新冠病毒感染实施“乙类乙管”，对于病毒变异是否会引发新一轮感染，我国将采取怎样的措施继续实施监控，中国疾控中心流行病学首席专家吴尊友就公众关心的问题进行了解答。
提问：大家都在担心国际上的奥密克戎BQ系列，包括XBB系列变异株，它们在我们实行“乙类乙管”，出入境打开以后，进入国内会掀起第二轮的感染，这是大家普遍担心的一个问题。
"We are tracking new strains circulating in various countries, and also monitoring for virus mutations in domestic outbreaks, especially for strains detected from travelers returning from overseas," said Wu.
Whether or not the variants will cause a new outbreak depends on how similar the mutated strain is in the structure to a recently circulated one, or how different they are in mutation, said Wu, adding that since the mutation is a sub-Omicron one, the risk is not high.
"Judging from the current results, all the strains we found so far have already been shared with international sharing platforms. They are the ones either reported abroad, or have been introduced to China after spreading overseas. So far, no newly emerged mutated strains have been found in China."
In order to improve the gathering and recording of statistics, the State Council joint COVID-19 prevention and control mechanism team has released a new epidemic surveillance plan for COVID-19 infection, said Wu. He mentioned that the country had "adopted a variety of comprehensively statistical methods to accurately evaluate the occurrence and development trend of the epidemic," adding that, "we can judge on the incidence, intensity, trend and timing of the epidemic, evaluating effect of its prevention and control."
