Here are my conclusions to date based on my own research
1. This originated in China in Nov and was probably in the US by late Dec/early Jan, particularly in the Seattle area. Agree
2. The real number of cases to date in the US is 10x than what is currently confirmed. So 300,000 instead of 30,000 as of today. Agree that the real case load is like 5-10x higher than we believe
3. Over 30% of cases are asymptomatic. They show no symptoms, don't get sick, but can spread it. Possible, but what are you basing this figure on. Have seen stuff that is all over the map from "very few" to "86%" of cases are asymptomatic. As such, I have no idea what to believe, but given the South Korea tested the heck out of their population and found very few asymptomatic cases, I'd bet your number is too high.
4. The real mortality rate is between .1 - .5%. Slightly worse than the flu. As above, what are you basing this on? South Korea was ALL OVER THIS and even they were only able to produce a .7% CFR. As such, that seems like best case scenario to me. Overburden the healthcare system and it can clearly be 5x or more of that figure.
I think our government officials are taking the right approach and that this will peak in 4 weeks and drop off within 8 weeks which will also coincide with warmer weather. I, too, am hopeful about the warmer weather and that our government is starting to do the right thing. Am concerned about our PPE shortage, our lack of testing, and our collective inability to act BEFORE it's too late. But agree that the peak is likely 4 weeks away. FWIW, had we acted sooner it could be 1-2 weeks away.
I reserve the right to be wrong about all of these things, but I think it accurate. I don't think you are wrong so much as overly optimistic on the % of asymptomatic cases and CFR. But I hope you are right.
