I don't think that math makes any sense at all. I'm saying that majority of infected aren't being tested whether they have symptoms or not. Vast majority of people with heavy symptoms are being tested, the less symptoms you have, the less likely you are being tested and many who have it are just riding it out at home. When more people are tested across all of the population the more the death rate goes down.
Death rate will be based on those infected who catch the disease, which is why we have to use case death rate. That is, final death toll will be what proportion of the world gets Covid19, and what proportion of them die. If the infection only reaches 10% of people, that's going to reduce the impact considerably, but AFAICS there's nothing to suggest the virus won't spread to everyone eventually (until herd immunity stops it). Of the people who do get the virus, some 50% have no symptoms, and then you have the rest. It's going to be a lot of people who get the disease in serious way.
It wasn't even close to being a best case scenario. About 1/3 of the passengers were 70 or older. A much higher age than the typical population. You overestimate the capabilities of the health care system on this decease. It's a virus to which there is currently no cure. Ventilators and such aren't doing any miracles, those who really need them face a grim outlook regardless.
If you take the Diamond Princess as indicative, only 11 people died out of 700 cases. That means 1.5%. So if that's the case, why are there thousands of dead in the UK? If 10,000 dead is 1.5%, then that means the total infected rate is over 650,000. You're suggesting the real infected might be an order of magnitude greater than recorded, but I don't think that theory holds. That could only be the case if either most people weren't showing any notable signs, or many, many people were getting ill but not being treated. Places that
tested everyone found 50% may be asymptomatic. It's far more likely that instead of having a massive unrecorded, asymptomatic infected population, it just isn't spreading that fast (which ties in with your comment about contagiousness) and what we see in reported and hospitalised cases is 50% of the virus, not just 10%.
I think you are twisting my points a bit...
Sorry, I don't mean to twist them, but I'm interpreting them. I guess what you're talking about is the R0 number. Indeed, the virus isn't very contagious in terms of people infected from each case. However, the exponential growth is still valid. Regardless how the virus compares to other viruses in terms of ability to spread, it was getting 12% growth daily. We had countries with cases doubling in 3-4 days. At the beginning of February, that's what China had...
Going by those umbers, 12,000 cases at the end of January and 20% growth per day would be 12,000 x 1.2^28 for February, which would be 2 million. By the end of March, that'd be 12,000 x 1.2^59 = 563 million.
I was in Thailand and Vietnam when the shit really started to hit the fan and the population density in some of the places there is such that if this virus really spreads like wildfire it would be game over there... I flew back to Finland on April 1st and in Bangkok tons of people were out, way less than normally, but still tons. Many had masks, but also many didn't.
That's because the R0 is low, as you say. That measure of contagiousness places SARS-Cov2 pretty low. However, in terms of its ability to spread and impact the population, exponential growth being what it is, yes, the whole world could have been infected in a few months.
...I specifically mentioned that if not contained the worst case scenario would almost stop the population growth for this year and that's about 80 million people dead from this.
Okay, I see that now. Although I didn't do the maths and just noticed you say the growth would be stopped for one year after saying in a previous post that growth was 200,000k a year, reading you as saying world deaths from Covid19 at worst would be 200,000.
80 million additional deaths probably shouldn't be waved off as barely registering.
