No we will not all get it. For numbers look at China with a population of 1.3 billion, 81,000 cases and 3,200 deaths.
Yes there is Italy and Spain but they will not " all " get it either.
The virus is fatal to the aged with existing respiratory problems, if these people got the flu ( kills 500,000 every year ) or pneumonia they would have also died.
I am not taking this lightly, took from the middle of March off and will not return to work until May ( spring breakup anyway ) go out only to walk the dogs or get supplies. Stocked up with 4 oz of top tier weed and new video games.
The people between 16 and 45 without respiratory issues need to keep out of the hospitals and let the aged people in, you will get sick but not die.
