Assuming the number of people who have reportedly died from COVID-19 is reasonably accurate, then the percentage of infected people who die from the disease (the death rate) must surely have been much lower than the 23% estimates commonly reported. That is because the number of infected people is much larger than the number tested and reported.
The triangle graph, from a February 10 study from Imperial College London, shows that most people infected by COVID-19 are never counted as being infected. That is because, the Imperial College study explains, the bottom of the pyramid represents the likely largest population of those infected with either mild, non‐specific symptoms or who are asymptomatic.
COVID-19 Cases
As the Director General of the World Health Organization (WHO), Tedros Adhanom, explained in his February 28 briefing, Most people will have mild disease and get better without needing any special care. Several studies have found that about 80% of all the COVID-19 cases have relatively minor symptoms which end without severe illness and therefore remain unreported.
A Chinese study in the Journal of the American Medical Association, February 20, found a case‐fatality rate of 2.3%, meaning 1,023 died out of 44,672 cases. But the total sample in that study (72,314) included an additional 27,642 non‐confirmed cases, and simply including cases (let alone unreported minor cases) would have reduced the fatality rate to 1.4%. China‐based estimates are largely confined to cases with the most severe symptoms, so it should be no surprise that the reported death rate among severe cases is much higher than it would be if the data also included most people who have a mild disease and get better. The risk of infecting more people is also more severe in China data, since severe cases are concentrated and transmitted in hospitals. This can also lead to overstated estimates of how many people are infected by someone with COVID-19, including the WHO reproduction number estimate of 1.42.5, which is mainly based on evidence from China.
As the graph indicates, other countries include more non‐severe cases than China does, notably by testing incoming travelers who arrive with a cough and fever. Even after casting a slightly wider net, however, the number of confirmed cases probably captures only about 30% of the actual number.
By the morning of March 2, there had been 89,253 confirmed cases of COVID-19 reported around the world, with about 96% of those in Asia. For comparison, the were an estimated 37.9 million people living with HIV in 2018.
It is worth noting that have also been 45,393 known recoveries from COVID-19 (compared to 3048 cumulative deaths) and, importantly, recoveries have been outnumbering new cases.
What about the relatively small number of COVID-19 cases outside China? In his February 28, the Director General of WHO reported that Outside China, there are now 4351 cases in 49 countries, and 67 deaths. Deaths of 67 divided by 4351 seems to demonstrate a death rate of 1.5%. But such calculations are highly misleading. They assume the denominator of that ratio (4351) is as accurate as the numerator (67). Yet people with mild cases who get better are unlikely to ever be included in the denominator.
If the WHO estimate of 4351 confirmed cases amounted to 30% of the actual number infected outside of China at that time, for example, then the combined total of both unreported and confirmed cases would be 4351 divided by 0.30 or 14,503. In that case, the actual death rate would 67 divided by 14,503, or less than one half of one percent (0.46%). Also, such death rates in the recent past are likely to come down over time, because they happened before promising new clinical trials of antiviral drugs that proved effective against more deadly viruses such as SARS, HIV and Ebola.
For perspective, the SARS coronavirus killed 774 people out of 8096 known cases in 2003, which was a death rate of 9.6% before it vanished the next year. Bird flu in 1997 was predicted to be a deadly pandemic, but it killed very few people before it disappeared. In its February 22 U.S. Influenza Surveillance Report, CDC estimates that so far this season there have been at least 32 million flu illnesses
and 18,000 deaths from flu. Dividing 18,000 by 32 million implies a low U.S. death rate of .0138% from the flu. Looking at the death rate alone is obviously not enough: We also have to look at the numbers of people infected, and the duration of the epidemic, which is why the flu killed so many more people than SARS. Still, it is important to avoid scaring people about the risk of death from COVID-19 by continuing to ignore the fact that the vast majority of cases have mild disease and get better without needing any special care.
Yet the numbers seem to be spiking up.
Still Trump’s fault. We need Truth rather than Facts.
Coronavirus hype is deliberate as well as purely political. This is the nothingburger of the century!!
If you take all who have died from corona, add that to those who have died from regular flu...
...is it the worst “flu season” ever?
I’m guessing: No.
There are lies, damned lies, and statistics.
The mathematics of statistics is only as good as the data collection. If there is incomplete data, either by not knowing what to look for, or deliberate exclusion, the computations are skewed and do not reflect reality.
Science, if practiced as it was intended to be, is NEVER settled. The collation of data is a primary tool in the building of scientific principles. Intellectual honesty is an absolute requisite. And even then, factors poorly understood get overlooked.
What numbers? Deaths? Or deaths per day? The total number will always get bigger, but the number of new deaths per day is trending down.
To put it into perspective, hospitals in Wuhan were overwhelmed with critically ill COVID-19 patients (that’s probably still the case) and it appears that is now happening in Italy.
Free hockey stick night at oldtimers hockey game at Michael Mann Arena. Henceforth it will be a felony punishable by death for harboring a septua or octo. Take them to your nearest GOV nursing home. BIG GOV mints will be handed out by nurse, Greta when they arrive. They/re BIG PHARMA approved.. She will check their voting records, their bank statements, their credit scores, their firearms purchases, etc,. etc. Anyone below our therapeutic levels...we will ask Greta to pull the plug on. It’s for your own good kids (inheritance) and ours (estate taxes). Eugenicist Bill Gates will text you the death certificate. We can ice them. It’s in the Constitution...er “Charter of Negative Liberties” according to that CONstitutional scholar, Barry. His credentials are impeccable. He won The Nobel POS Prize one year.

Based on the ratio of cases to population, Italy looks more like an emerging market than a developed country.

Gee, I wonder what the average age is of someone dying from the regular-run-of-the-mill flu that kills tens of thousands of people every year? Hmmmmmmmmmmmm
gee i wonder what the average age of anyone dying is?
life expectancy?
-——I wonder what the average age is of someone dying from the regular-run-of-the-mill flu——
A more meaningful number would be what percentage of those who have the flu and die actually have pneumonia.
Ditto the corona virus
I wonder if Italy has a lot of tourism during the winter months - something I don’t expect to be the case in Germany.
I am personally more frightened by the mathematical ignorance in this country than by the germs.
Now they are saying the death rate is closer to 1% (mostly infirm elderly) once we dilute the number with more tests.
False
Here is the up to the minute data
116,000 cases world wide. 105,000 mild or recovered.
4089 deaths
Average age of the dead, 80 years old.
