COVID-19: size, real image I'm an electronics engineer. I was thinking about how to detect the presence of COVID-19: 1. Obtain the sample. 2. Increment image/sample, (I need the real size to determine increment/magnification) 3. Digital image processing — detect presence using artificial intelligence or Recognition. What is the approximate size of COVID-19? Is there a real image of COVID-19?

> 2019-nCoV also has enveloped virions that measure approximately 50–200 nm in diameter with a single positive-sense RNA genome.
