Sweeping US Navy testing reveals most aircraft carrier sailors infected with coronavirus had no symptoms
"What we've found of the 600 or so that have been infected, what's disconcerting is a majority of those, 350 plus, are asymptomatic," he said, adding, "So it has revealed a new dynamic of this virus that it can be carried by normal, healthy people who have no idea whatsoever that they are carrying it."
So we can infer that close to 60% of this sample group whose average age is probably in their mid 20s, and above average in terms of fitness, will be asymptomatic. Hopefully the Navy will give follow-up and disclose how many of those with symptons require hospitalization and so forth. Keep in mind, this sample group most likely does not include many obese, diabetic, or otherwise health compromised individuals and most would be young in age. Compare that to the Diamond Princess, where the sample group would have been older and contain a number of maladies. The general US population is probably more like those on the Diamond Princess.
Diamond Prinecss:
3618 tested
712 cases
331 asymptomatic (46%)
13 deaths (1.8%)
Roosevelt
4800 tested
approximately 600 cases
approximately 350 asymptomatic (58%)
deaths?
This doesn't square with the Stanford study or the Boston Homeless survey where the number of asymptomatic far outweighs those with symptons.
