英國牛津大學Jan M. Brauner等研究人員合作評估了各種政府干預措施對COVID-19控制的有效性。這一研究成果於2020年12月15日在線發表在國際學術期刊《科學》上。
研究人員收集了有關2020年1月至2020年5月底幾個歐洲國家和其他國家/地區實施非藥物幹預(NPI)的時間順序數據。研究人員估計了NPI的有效性,範圍從限制聚集規模、商業關閉、關閉教育機構到送貨到家。為此,研究人員使用了貝葉斯分層模型,該模型將NPI實施日期與國家案例和死亡人數相關聯,並通過廣泛的經驗驗證來支持結果。關閉所有教育機構、將聚會限制在10人以內,以及關閉面對面的業務均大大減少了傳播。送貨到家的附加影響相對較小。
據悉,各國政府正在嘗試通過NPI來控制COVID-19大流行。但是,人們對不同NPI減少傳播的有效性了解甚少。

Abstract: Governments are attempting to control the COVID-19 pandemic with nonpharmaceutical interventions (NPIs). However, the effectiveness of different NPIs at reducing transmission is poorly understood. We gathered chronological data on the implementation of NPIs for several European, and other, countries between January and the end of May 2020. We estimate the effectiveness of NPIs, ranging from limiting gathering sizes, business closures, and closure of educational institutions to stay-at-home orders. To do so, we used a Bayesian hierarchical model that links NPI implementation dates to national case and death counts and supported the results with extensive empirical validation. Closing all educational institutions, limiting gatherings to 10 people or less, and closing face-to-face businesses each reduced transmission considerably. The additional effect of stay-at-home orders was comparatively small.
