The two in my family who’ve had it, one currently, would argue that it’s more than a bad cold. More like severe flu. I saw it first hand with my spouse. Nobody has to be taken to ER for a bad cold. That said, for the lucky some it might act like just a cold, and I hope when my time comes I’m one of them.
Guess you never heard of pneumonia which is a bad cold which is also caused by coronavirus.
As I just posted Coronavirus is a cold, rhinovirus is the flu.
Covid 19 is nothing more than a bad cold for some and the some being “very few”.
