It is postulated that the reflux could have contained droplets of contaminated sewage present in the soil stack , be dispersed into the bathroom , and be extracted by the bathroom exhaust fan into the light well between adjacent units . the contaminated droplets could then enter other units through open windows 我们推测这气流可能把存于污水管内带病毒的水滴散发至浴室内,而浴室的抽气扇亦可能把这些水滴排放在分隔相邻单位的天井,最后带病毒的水滴通过窗户进入其他单位。
