麻省总医院在重疫区Chelsea镇街头抽查了200个路人的血液,唯一要求是不能是确诊病例。发现其中64人(32%)有新冠病毒抗体。该镇有大约4万人口,712个确诊病例,39人死亡。如果抽查结果能够外推,该镇已有13000人被感染,病死率0.3%。
根据这个比例,加拿大全国平均感染率达32%,可能将近4万人死亡;大约要死掉8万人之后,才出现群体免疫现象(人口中70%有新冠病毒抗体)。
这和我之前用瑞典数据推算结果(7.5万)基本一致:https://forum.iask.ca/threads/900608/

Nearly a third of 200 blood samples taken in Chelsea show exposure to coronavirus - The Boston Globe
A Mass. General researcher says the results point to a "raging epidemic," but may also indicate the city is further along the disease curve than some other municipalities.
