Numbers can sometimes be slippery things.  Attempting to draw conclusions from incomplete data is fraught with even more time flat on the ice.

The 85-fold estimate came from a public health expert and was a prediction of one month's growth in the US - and only the US - infection rate. It is not valid to apply the US growth rate to the entire world.

This link starts at about the 4 minute mark (after introductions). The following 14 minutes gives context for the 85 fold number.

The point is that the US is weeks behind much of the world, and about 2 weeks behind Italy.  Unlike Italy and most of the rest of the so-called 'developed world', we are not testing.  Two days ago only EIGHT tests were performed in the US as a whole (reported by The Hill).  There are reported to be about 40 cases in Florida, but those number aren't yet in the 'official' numbers being scraped to generate the dashboard at Johns Hopkins.  We're not testing, therefore our data are bad and that means conclusions of those data are invalid.

The attempted calculations for China and the rest of the world and the attempt to declare the flu has a higher death rate are not valid.  Why?  You began with 'confirmed cases', decided that reflected the actual number of  people "infected", and then used that number to determine the death rate.  Sorry - that doesn't work.  We don't know how many are infected.  

Based on what we've seen so far from countries doing much better than the US, this virus is working through most of the population, it's killing between 2% and 45% of those with confirmed cases, and some of the people that recover have permanent lung damage (20-30% less lung function).

  The death rate for the 1918/1919 H1N1 pandemic is reported to be 2.5%.  So far, using the numbers reported by the Johns Hopkins 'dashboard', the death rate for this pandemic is 3.5%.  Based on the wide range of data discrepancies (Iran digging mass graves, anyone?) and that this pandemic is less than 2 months old, I wouldn't be surprised if the rate is closer to 7%.
  This isn't the flu.  It's not a hoax.  Coronavirus doesn't care how we vote.  Nobody needs to panic, but it is a serious situation that should not be taken lightly.

In the last 30 days, China's infection rates have plateaued, and most are returning to work.  Johns Hopkins has a wonderful dashboard for data visualization that I recommend https://coronavirus.jhu.edu/map.html.

If an 85 fold increase in infections holds true, in one month, 11 million people will have been infected - which is still only 0.0015% of the world population.
If an 85 fold increase in deaths holds true, in one month, 432,000 people will have died.  That's 2% of the number of people who died from the 1918 flu... and right in the average estimate for annual influenza deaths (per the WHO - https://www.who.int/news-room/fact-sheets/detail/influenza-(seasonal) ), and the same number (approximately) who died from the 2009 H1N1 (swine-flu) outbreak ( https://pubmed.ncbi.nlm.nih.gov/22738893 ).

Hubei province of china, the origination of COVID-19, and the source of 60% of all deaths from it worldwide (3,062 as of this email) - has had a total of 67,786 confirmed cases.  Since it has a population of 58.5 million people, that works out to just over 0.1% of their population having been infected.

Italy, the next highest reporter has had 15,113 confirmed cases, and 1,016 deaths.  With a 2011 census of 59.4 million, that works out to 0.025% of their population having been infected.

I think everyone should use caution, take appropriate precautions, and most importantly - wash their hands.  I think everyone should make decisions for themselves on what they feel safe doing.  I also think these are the same things that most health care professionals have been saying - for every infectious disease - every year - for decades.

 

I'm saddened that Ozarkcon has been canceled - but if there's a silver lining - We'll all now be able to participate in the Missouri QSO party, it looks like!  I'm expecting quite a good showing in the QRP category!  (Rules are here:  http://w0ma.org/images/MOQP2020/MO-QSO-Party-Rules-2020.pdf )

Hi Andy,

It's not enough to quote overall rates - it's _very_ age dependent.  Kids under 15 don't seem to get any symptoms, but can transmit asymptomatically.  I don't recall seeing any deaths reported below the age of 34, but that's at least a day old now.  For people _WITH_NO_UNDERLYING_CRITICAL_HEALTH_CONDITIONS_ under the age of 50, the rough estimate is now less than 1% for ages 50 - 60, about 1% for ages 60 - 70, a few percent for ages 70 - 80, and upwards of 15% for ages 80+ (who are already above the overrall average age of death and uniformly tend to have some sort of underlying health condition).  Those over 80 constitute about eight percent of the U.S. population, so that could mean 4.2 million people _if_all_of_them_get_infected_ and the numbers are worth anything, which is more than debatable.

The key is to keep elderly and high-risk people isolated, and those who care for them directly must self-quarantine, performing intensive cleaning when handling anything delivered by people who must not enter the quarantine spaces.  Everyone else should minimize movement, stay at least six feet away from others, and perform intensive cleaning, coughing into sleeves, not sharing any material with anyone else, etc.

Take good care and

Hi John,
Sorry i did not hear you.
i have found 14285 full of buzzing noise so have been using 14280 kHz.
Yes, the 319 was very expensive. The little hermetic TCXO alone cost $3000 (1987 dollars).
Here is my log for the day:
