继全球239名科学家发表公开信呼吁世界卫生组织重视新冠病毒空气传播后，日前世界卫生组织发布新指导意见称，不排除新冠病毒在室内通过空气微粒传播的可能性，但还需要进一步调查来证实。 Healthcare workers assist a resident in putting her mask on outside of a public housing tower, reopened the previous night after being locked down in response to an outbreak of the coronavirus disease (COVID-19), in Melbourne, Australia, July 10, 2020.
