Pneumonia is the inflammation of the lung. You will find covid patients more reliably through lung CT than nucleotide tests of swabs. People are confused about what "mild" means: https://www.nytimes.com/2020/03/04/health/coronavirus-china-aylward.html https://www.nytimes.com/2020/03/04/health/coronavirus-china-... What were mild, severe and critical? We think of “mild” as like a minor cold. No. “Mild” was a positive test, fever, cough — maybe even pneumonia, but not needing oxygen. “Severe” was breathing rate up and oxygen saturation down, so needing oxygen or a ventilator. “Critical” was respiratory failure or multi-organ failure. So saying 80 percent of all cases are mild doesn’t mean what we thought. I’m Canadian. This is the Wayne Gretzky of viruses — people didn’t think it was big enough or fast enough to have the impact it does.
