Conservative Main land china population: 1.3 billion

High end Number of infections in China after 2+ months of infections: 80,000

Chance of getting disease = 80,000/1,300,000,000 = 0.006% (Rounded up)

Death rate = ~2% (higher if age >70, 0.2 if under 40).

Bay area population 7 million Bay area x contagious rate = 400 people Actual number with it after February ~ 0

Likely due to younger age of population, but also fairly low infection rate to begin with.

Across US Population = 300,000,000 High Estimate of infections based on infection rate = 18,000 Multiple by 6 to get a full year, would be 100,000; death rate would equal 3,000 (This seems way to high to me)

Bayesian updated due to awareness, preparation and suspicion I would actually estimate about a tenth of cases. Yes other countries haven’t had a chance to spread disease, but china is actually controlling it since the initial outbreak.

Given an additional 10 months in 2020 but weighed against the actual very few infections here at present. I stick with the same estimate of 10,000, deaths about 300.

Given influenza past infection season numbers from 100,000 - 1,000,000 this seems pretty low.

It appears influenza has a higher infectious rate but lower death rate. This fits given that influenza has established itself across continents and has a readily available vaccine, and while the vaccine may not fully prevent the disease, it often provides some protection and has been proven to lower death rates of populations who receive it.

I suspect in following years coronavirus may reach these numbers once the virus has dispersed sufficiently across countries but with better protocols and possible vaccine in future years it will likely be similar to influenza based on the numbers presented.

Curious what other peoples estimates are.

Curious if people start pulling out the plague bird masks.

(If they used bird masks to scare mice, we should use human or lion masks to scare pangolins. Or we should use hawk masks to scare bats. If we use hawk masks, they need a hawk call)

To answer your question, given that there are between 0-4 cases at the end of February, I estimate 0-4 cases at the end of February.

Good day.
