No evidence of a less deadly form. However, there is growing evidence that the strain in Italy in New York represents a more deadly form. Hopefully they will contain it soon.
Yes, they are making progress but slowly. They recently had very positive results with dexamethasone in clinic trials for severe cases. They have also learned not to put people on ventilators unless every other approach fails. A lot of patients died early on due to premature intubation because they were worried about exposing staff to the virus. Now they use a combination of prone positioning (lying on your stomach) and Low-molecular weight heparin with passive oxygen with good results. We're learning a lot about the immune response that will lead to better treatments but we haven't testing them yet. For example activation of CD8+ T-cells seems critical and deactivation of platelets during the immune response may lead to improved survival. So we may be looking at using CAR-T or other methods to do this in future.
The Oxford vaccine is now entering a trail phase involving tens of thousands of subjects in the UK, Africa and Brazil. So we'll have results from that soon that will be significant. Many other smaller trials are underway.
