这是香港淘大花园的情况。2003年同一小区331人确诊、42人死亡。其实每天向下水道下面倒稀释过的bleach即可 2020年3月，我通过一个权威警告了政府。不过他们有没有听我就不知道了。当时我的信： By now (March 31, 2020), there is no direct evidence that some SARS-CoV-2 patients have been infected through faecal-oral transmission. However, there is direct evidence that the SARS-CoV-2 virus is found in the faecal of patients. And in 2003, a similar virus, SARS-CoV, could have infected hundreds of people in Hong Kong through faecal-oral transmission. In 2003, an epicenter of the SARS-CoV outbreak was the Amoy Gardens in Hong Kong. There were 321 SARS cases in the Amoy Gardens by mid-April, and 41% of them were in Block E (Cotruvo et al, 2004). "Environmental investigations (Hong Kong Department of Health 2003) indicated that the U-trap in the bathroom floor drains were usually dry and that there was a cracked sewer vent pipe in Block E. Tests with oil droplets suggested that aerosols traveled upwards in the light wells (utility channels) between each floor and that droplets could enter a bathroom through the floor drain because of negative pressure generated by exhaust fans when the bathroom door was closed." (p39, Cotruvo et al, 2004) Thus, Cotruvo et al (2004) suggest "Given that the SARS virus is excreted in faeces and these results, it seems possible that SARS could have been transmitted through wastewater droplets." (p39). SARS-CoV RNA was found in the sewage water of two hospitals in Beijing treating patients with SARS. (Wang et al, 2005) The discussion of faecal-oral transmission of SARS-CoV-2 started in Feb 2020, based on the similarity between SARS-CoV-2 and SARS-CoV/MERS-Cov. One example is the paper on The Lancet by Yeo et al. (2020). But the authors did not provide any evidence. The first evidence comes from Holshue et al. (2020). In this paper, Table 2 shows a positive case in the stool on Illness Day 7 (stool not tested on other days). In a study in Singapore (Ong et al, 2020), SARS-CoV-2 virus is found in the toilet bowl. To sum, SARS-CoV-2 virus can be found in the faecal of patients, and it is possible to travel through malfunctioning sewers and floor drains. That''''''''s why I suggested sanitizing the toilets and drains. References: Cotruvo, Joseph A., et al., eds. Waterborne zoonoses. IWA publishing, 2004. Holshue, Michelle L., et al.

上周收到l close contact 警告，然而已经休假一个月了，唯一可能性就是楼上喜欢浪的年轻couple，没什么事还经常party，我能听到女孩的咳嗽声，已经两周多了，那也没耽误他们浪，只能cross fingers 了。 shirley951951 发表于 2022-01-04 09:13
你这个密接 细思极恐啊 CDC规定 For COVID-19, a close contact is anyone who was within 6 feet of an infected person for a total of 15 minutes or more over a 24-hour period (for example, three individual 5-minute exposures for a total of 15 minutes).

美国只要按code做的水管，绝对可以阻绝空气。
每天向下水道下面倒稀释过的bleach即可
空气也不可能，新楼房都是Havac系统，室内自循环。
你的意思是你们已经一个月没出门了，但是接到自己是密接的通知？
就是啊。。这的公寓没有地漏的
而且如果地漏干了室内不会很臭吗？。。难道不会发现？
对，除了人少时候去超市，也就两次…然而我们这里超市人人戴口罩…所以肯定是楼上，天天咳嗽…..今年死活要买房了。
在美国? 美国啥地方隔壁邻居阳性都算密接?
如果是金属下水管道估计也没几年就要被腐蚀的不成样子。短时间是没有问题的，也能解决一些现在的问题。
这个确实是。以前住公寓，邻居抽大麻，味道到处都是

嗯 我以前也是闻到过隔壁抽烟的味道的 这里的密封做的很差
这是什么通风管道
