Jackstraw,
Sorry to hear of your loss this indeed is a terrible virus. Prayers to you and his family. There will be so much more to learn about this virus going forward. Being of older age, Obese, Diabetic, Male, Metabolic syndrome, history of smoking and smoking or environmental dust related illness, active asthma and a myriad of other factors increase the risks of getting into trouble with this virus. hydroxychloroquine has shown some positive effects and Remdesivir is showing promise although its stressed these are both early in the clinical trial process.
