A cohort study to evaluate the effect of combination Vitamin D, Magnesium and Vitamin B12 (DMB) on progression to severe outcome in older COVID-19 patients: Conclusions: DMB combination in older COVID-19 patients was associated with a significant reduction in proportion of patients with clinical deterioration requiring oxygen support and/or intensive care support. This study supports further larger randomized control trials to ascertain the full benefit of DMB in ameliorating COVID-19 severity.

Les États-Unis sont-ils en voie de "tiers-mondisation"? Avec plus d’un million et demi de cas et plus de 100 000 décès recensés, les États-Unis paient un lourd tribut au Covid-19. Mais la crise sanitaire révèle surtout un pays miné par les inégalités, profondément ségrégué, où le rêve américain ne semble plus qu’un lointain souvenir.

Digital Contact Tracing for Pandemic Response - Ethics and Governance Guidance

European government officials call for tech companies to loosen grip on contact-tracing technology: The governments were joined this week by a group of 27 doctors and researchers who published a report, led by Johns Hopkins University, that suggested technology companies should not “control the terms, conditions or capabilities” of digital contact tracing. Public health officials have also urged Apple and Google to allow more access to smartphone operating systems for the purposes of contact tracing.

So Where Did the Virus Come From? So what did happen? At present, the evidence is pointing tentatively to a chain of person-to-person infections occurring somewhere outside a city before somebody brought the virus to Wuhan, where the market acted as an amplifier. The first case could have been a rural farmer or possibly a bat researcher collecting samples for virologists. Or it is possible that another animal was involved in some way, with the virus bouncing between a farmer and his animals, or a wildlife smuggler and his poor pangolins.

There are more coronaviruses out there. If the evidence is pointing away from wildlife markets, and if the Chinese authorities are confident it wasn’t a laboratory leak, they should be eager to help the world find out what did actually happen.
