在4月6日国务院联防联控机制新闻发布会上，有记者就奥密克戎危害性提问。北京大学第一医院感染疾病科主任王贵强表示，“奥密克戎危害性远远高于所谓的流感，尤其对于未接种疫苗或没有全程接种疫苗的老年人。”

Despite being weaker than previous COVID-19 variants¹, Omicron is still much deadlier than flu, especially for those who are not fully² vaccinated³, experts said on Wednesday.

 

他以香港疫情为例，称“香港特区数据显示目前有110多万感染者，死亡8000多例，总的病死率是0.7%，病死率0.7%远高于流感的病死率。”

The overall COVID-19 mortality rate in Hong Kong is about 0.7 percent, significantly higher than that of the seasonal⁴ flu, Wang Guiqiang, director of the Infectious Diseases Department at the Peking University First Hospital, said at a press conference of the Joint⁵ Prevention and Control Mechanism⁶ of the State Council on Wednesday.

 

王贵强指出，香港疫情数据给我们一个非常重要的提示，疫苗接种与否与病死率关系密切。从香港病死人群数据看，没有接种疫苗的病死率是3.2%，接种一针的病死率0.96%，接种两针的病死率是0.14%，接种三针的病死率0.03%。从这个数据来看，三针疫苗接种可以有效降低奥密克戎感染后的病死率。

"A great hint the data of Hong Kong gave us is that the patient's death rate is closely related to their vaccination⁷ status," emphasized Wang, saying that "the mortality rate in Hong Kong could fall from 3.2 percent to 0.96 percent if the patients receive one dose of vaccine⁸. The death rate will further be reduced to 0.14 percent with two doses and 0.03 percent with three doses of vaccine."

 

王贵强表示，目前，我国流行的奥密克戎毒株从整体来看，无症状感染者和轻型病例比较高。一方面是因为奥密克戎本身毒株毒力相对有所下降，上呼吸道感染为主，下呼吸道感染比较少，肺炎发生率比较低。另一方面，是因为目前疫苗接种的本底之下，疫苗接种人群重症比例明显是低的。第三是主动核酸筛查，很多病人是在潜伏期发现的，所以无症状感染者比例相对是高的。此外年轻人、青壮年感染奥密克戎毒株后无症状感染者和轻型病例比较高。

 

对此王贵强表示，目前仍不能麻痹大意，一方面，要采取积极有效的防控策略。另一方面，一定要积极推动疫苗接种，加强疫苗接种力度，尤其是老年人、有基础病的。老年人要积极接种疫苗，尤其是加强免疫，第三针的接种至关重要。

Wang urged the elderly and those with underlying⁹ health conditions to get vaccinated and especially take a booster shot to truly reduce the ferocity of Omicron.
