Advice from Stanford University Taiwan experts provide a simple self-check that we can do every morning: Take a deep breath and hold it for more than 10 seconds. If you do this successfully without coughing, without discomfort, stiffness or tightness, there is no fibrosis in the lungs; it basically indicates no infection. In critical times, please self-check every morning in an environment with clean air. Serious excellent advice by Japanese doctors treating COVID-19 cases: Everyone should ensure your mouth & throat are moist, never dry. Take a few sips of water every 15 minutes at least. Why? Even if the virus gets into your mouth, drinking water or other liquids will wash them down through your throat and into the stomach. Once there, your stomach acid will kill all the virus. If you don't drink enough water regularly, the virus can enter your windpipe and then the lungs. That's very dangerous. * Snopes says this is fake news ! Please copy a
