Sanjay Gupta, consider this about the Coronavirus
What if Seniors get pneumonia because they are mouth-breathers and the virus goes directly to the lungs instead of getting filtered by the nose/sinuses. You still end up with a head cold but maybe by then an adequate immune response has mounted. I got this idea yesterday by seeing the CEO's standing behind Mr. Trump--they were all tight-lipped, not talking or even licking their lips--as if they were told not to breathe through their mouths. I think Mr. Trump will test positive, btw. During one clip, he was looking peaked and speaking hoarsely.
