On this, our 325th Evolutionary Lens livestream, we discuss Hanta virus and drought. First: what is the natural history of Hantavirus, do any Hantaviruses transmit directly from human to human, and what is going on with the M.V. Hondius, the cruise ship on which Hantavirus has made a stand? Given its mechanisms of action, Ivermectin is likely to treat Hantavirus (a negative sense single-stranded RNA virus), but the WHO dismisses the possibility. Moderna is working on a Hantavirus vaccine, even though the Number Needed to Treat is sky high. What is going on? Then: in Washington state, we’re experiencing a very wet drought. The Department of Ecology has declared a drought (again), and the snow pack is low, but all other indicators—from rivers to reservoirs to soil moisture—are excellent. Cliff Mass, atmospheric scientist, puts the evidence in one place and calls bull on the drought diagnosis. ***** Our sponsors: Xlear: Xylitol nasal spray that acts as prophylaxis against respiratory illnesses by reducing the stickiness of bacteria and viruses.
