sister-in-law's boyfriend has the flu (B). They told him ibuprofen, dayquil and fluids...don't think that's going to work for Coronavirus..
That's exactly the treatment recommended for Coronavirus (minus the DayQuil). The vast majority of cases are quite mild, like a cold.
As a professional scientist, my opinion is that they're going to find that Coronavirus is far less deadly than the 2% mortality rate that's been reported, due to the non-diagnosis of the milder cases. Once it spreads into a more medically-prepared country a better idea of the actual mortality rate will probably emerge.
