Yet the CDC preliminary hospitalizations estimates for 2019-2020 seem to match those for 2016-2017 and 2018-2019 and that was calculated up to April 4.
Testing for CV-19 was already a thing in Italy by mid february.
So, when did these anti-body tests take place?

You have any other numbers we can work with?
My thoughts are, if they fudge them the same way then at least they can be used to compare with each other.

That second link shows the article was published April 2nd.
Doesn't really do anything for the theory that CV was floating around long before the first cases.

Because they tested positive a month and a half after the virus was shown to be in their country. They could have been infected and been asymptomatic or shrugged it off because the symptoms were mild.
It does not prove that they were infected late last year or before CV was detected. Not saying they couldn't have but a positive test on that date isn't conclusive.
The spread of a novel pathogenic infectious agent eliciting protective immunity is typically characterised by three distinct phases: (I) an initial phase of slow accumulation of new infections (often undetectable), (II) a second phase of rapid growth in cases of infection, disease and death, and (III) an eventual slow down of transmission due to the depletion of susceptible individuals, typically leading to the termination of the (first) epidemic wave. Before the implementation of control measures (e.g. social distancing, travel bans, etc) and under the assumption that infection elicits protective immunity, epidemiological theory indicates that the ongoing epidemic of SARS-CoV-2 will conform to this pattern.
...
Our simulations are in agreement with other studies that the current epidemic wave in the UK and Italy in the absence of interventions should have an approximate duration of 2-3 months, with numbers of deaths lagging behind in time relative to overall infections. Importantly, the results we present here suggest the ongoing epidemics in the UK and Italy started at least a month before the first reported death and have already led to the accumulation of significant levels of herd immunity in both countries. There is an inverse relationship between the proportion currently immune and the fraction of the population vulnerable to severe disease.

I guess you have not heard that a lot of people get Covid and don't even go to the doctor because they don't feel that sick, if at all. On the other hand, just like the flu, it can kill a lot of people, it might kill many more than the flu, but nobody knows for sure because it is a new virus.
It is this uncertainty, coupled with the deaths in places like Italy, France, Spain and even Sweden, that have people exercising caution.

It says 505,000 active cases in the US.
Do you think that represents all infections?
