研究称，如果人们广泛的戴口罩可以防止新冠肺炎的第二波

根据英国周三发布的一项研究，人们广泛的使用口罩可能会将新冠肺炎的传播推低至全国流行病的可控水平，并可能在与封锁相结合的情况下防止大流行疾病的进一步浪潮。这项由英国剑桥大学和格林威治大学的科学家领导的研究表明，仅靠封锁并不能阻止新型SARS-CoV-2冠状病毒的卷土重来，但如果有足够多的人在公共场合佩戴自制口罩，那么即使是自制的口罩也可以大幅降低传播率。“我们的分析支持公众立即和普遍采用口罩，”剑桥大学这项研究的共同负责人理查德·斯图特(Richard Stutt)说。

Population-wide use of masks could drive the spread of COVID-19 down to a manageable level of the national epidemic, and could prevent further waves of pandemic disease if combined with closures, according to a UK study released on Wednesday. The study, led by scientists at the University of Cambridge and The University of Greenwich in the UK, shows that a blockade alone will not stop the resurgence of the new SARS-COV-2 coronavirus, but even homemade masks can significantly reduce transmission rates if enough people wear them in public. "Our analysis supports the immediate and widespread adoption of masks by the public," said Richard Stutt, co-leader of the Cambridge study.  source
