I have a old friend who is positive now...found out through FB. 29 years old, construction worker, in good shape and doesn’t smoke or drink. He lives in DC and went to the ER a couple nights ago because of difficultly breathing suddenly.
He apparently had a very low fever for a few days, and a cough. Then he got better for a while and out of the blue got much much worse. He had those symptoms for maybe 10 days before the breathing issues started, and then he isolated himself. But during that time he probably was around 100s of people.
