The effect of temperature on persistence of SARS-CoV-2 on common surfaces Virology Journal. From the Abstract: “While the role of fomite transmission is not yet fully understood, precise data on the environmental stability of SARS-CoV-2 is required to determine the risks of fomite transmission from contaminated surfaces.” In the lab, in the dark (no UV): “We obtained half lives of between 1.7 and 2.7 days at 20 °C, reducing to a few hours when temperature was elevated to 40 °C. With initial viral loads broadly equivalent to the highest titres excreted by infectious patients, viable virus was isolated for up to 28 days at 20 °C from common surfaces such as glass, stainless steel and both paper and polymer banknotes. Conversely, infectious virus survived less than 24 h at 40 °C on some surfaces.”
COVID-19: faecal–oral transmission? Nature. From March, possibly germane: “”Physicians and caretakers of potentially-infected children need to be aware that stools might be infectious,” adds [Mary Estes at Baylor College of Medicine]. The results are preliminary and further research is needed. ‘We are now assembling a much larger cohort to confirm our results and will test more patients to confirm faecal–oral transmission,” says [Kang] Zhang.’” Worth adding to the fomite v. aerosol discussion; there was, after all, a fecal plume in Amoy Gardens case, during 2003’s SARS outbreak in Hong Kong.
Go long domestic tourism, because passports are gonna be a problem. (To be fair, it would be nice if this service was like BLM marches (no known cases), and not like indoor political rallies (cases), or Wisconsin in-person voting (cases). It is outdoors. But I’m not seeing masks, people are singing and shouting, and they remain close to their neighbors for an extended period of time. So I’m not hopeful. Tennessee isn’t doing well, either.)

Like we always say on RWN, it helps to look at the maps. And then it’s good to add a topographic map. Here you can see that the Azerbaijani advances (green arrows) are in the south, where there’s flat land… pic.twitter.com/TVRDPdQBre
Lord Advocate Launches War on Twitter Craig Murray (GF). “[T]he Lord Advocate of Scotland is claiming in the contempt of court case against me that I am legally responsible for the content of replies to my tweets…. But neither you nor I nor any other user is the publisher of Twitter. There is no sensible view in which you are the publisher of replies to your tweets. Twitter is the publisher of tweets and users are responsible for what they tweet.”
Further to my post on “bureaucratic” barriers to “access,” we have this (flora):

Health Care: The Best and the Rest New York Review of Books. Review of Ezekiel J. Emanuel’s new book. “Emanuel sees automatic enrollment as both essential and nonthreatening—a social good requiring little systemic change.” If Emanuel thinks that, he’s out of his mind, and not just because the Freedom caucus will hate it.
