cord-271862-jk37ej4c	Qian, Hua	Indoor transmission of SARS-CoV-2	2020-04-07		.txt	text/plain	3817	250	61	Methods: Case reports were extracted from the local Municipal Health Commissions of 320 prefectural cities (municipalities) in China, not including Hubei province, between 4 January and 11 February 2020. Conclusions: All identified outbreaks of three or more cases occurred in an indoor environment, which confirms that sharing indoor space is a major SARS-CoV-2 infection risk. 2 Since 20 January 2020, the local health authorities of cities outside Hubei have reported online the details of most identified cases of infections. In this study, we identified the outbreaks from these case reports from the local Municipal Health Commissions of 320 prefectural cities (municipalities) in China, not including Hubei province, between 4 January and 11 February 2020 and reviewed the major characteristics of the enclosed areas in which these outbreaks were determined to have occurred and associated indoor environment issues. We collected descriptions of each confirmed case from the local Municipal Health Commission website of 320 prefectural cities in mainland China, not including Hubei province.	./cache/cord-271862-jk37ej4c.txt	./txt/cord-271862-jk37ej4c.txt
