MUST READ for those still wondering why Coronavirus is a bigger deal than Seasonal flu? Here it is in a nutshell. I hope this helps. Feel free to share this to others who don’t understand...
It has to do with RNA sequencing.... I.e. genetics. Seasonal flu is an “all human virus”. The DNA/RNA chains that make up the virus are recognized by the human immune system. This means that your body has some immunity to it before it comes around each year... you get immunity two ways... through exposure to a virus, or by getting a flu shot.
