What it is ain't exactly clear

This is a graph of Covid 19 deaths per million population of the USA and various countries in Europe. It shows that the pandemic has followed a similar curve in these countries, with deaths rising rapidly, and then slowly going down over a period of 60-80 days.

84221

A recent study by an Israeli mathematician proposed that the virus follows a similar curve in most counties, rising up and then going down over a period of 70 days. He doesn't think lockdowns have much effect.

Two recent scientific papers have proposed that their may be some preexisting immunity to covid 19 through previous exposure to other coronaviruses like the common cold.

Using diverse assays for detection of antibodies reactive with the SARS-CoV-2 Spike (S) glycoprotein, we demonstrate the presence of pre-existing immunity in uninfected and unexposed humans to the new coronavirus.

New York City, with more cases and deaths than anywhere, follows a similar curve.

From NYC Health: Daily deaths from 3/15 to 5/17 (dark blue is confirmed, light blue projected)

84222

COVID-19: Data Summary - NYC Health (https://www1.nyc.gov/site/doh/covid/covid-19-data.page)

So some say these curves are caused by lockdowns, but some countries like Sweden never really locked down, and others that started opening up a month ago are not showing huge spikes in new cases and deaths.

We know that covid 19 is more infectious than common flu, about twice as much, even the H1N1 flu. But yearly influenza infections dwarf what covid 19 has done in terms of infections. On average, 30 million Americans get the flu each year, and we have partially effective vaccines for the flu. It's possible that there will be a second wave and covid 19 will rack up higher numbers, but nobody knows for sure. SARS, a similar coronavirus, was global and then just faded away, has not returned. They don't know exactly why.

• Number of flu cases U.S. 2010-2017 | Statista (https://www.statista.com/statistics/861113/estimated-number-of-flu-cases-us/)

So why is this virus, more infectious than even the most virulent strains of the flu, not infecting and making more people sick? A recent antibody test was done in New York which estimated 21% of New Yorkers had been infected, but never got sick, called their Doctor, and got a test confirming the disease. They were immune in some way.

So what does all this mean? Perhaps a large portion of the population does indeed have some kind of immunity, possibly from previous exposure to other coronaviruses like the common cold, and this immunity is stronger in younger, healthier individuals who rarely die if infected.

I suspect the warming trend in the weather could be a factor of some significance that is a common denominator for most locations presented.
We won't know for sure until we have gone a full cycle.

We could also be witnessing the trends established during the pre shut down and post shut down implementation and effect(s).

Again the longer the cycle measured the more will be learned.

I'm not sure about the warming trend thing. I recall a study that said chances of infection start to go down at 77 degrees or so. New York City has only reached that temperature once this year, on May 15. March and April had highs in 50s and 60s yet their daily death and case numbers started falling at the beginning of April. Miami area has the most cases in Florida and they've had highs in the 80s and 90s since March.

Sweden, which did not lockdown, has gone from a high of 98 daily
deaths in mid March to 53 yesterday. I'm not sure that's a lockdown effect.

Yes, but it's the same for all countries plotted and they all show similar curves. Also, the chart of NYC daily deaths is not logarithmic and shows similar fast rise and then gradual decline.

I agree that lockdowns slow things down. I also think the virus was circulating in places like New York long before they even thought about locking down.

Anyway, the similarity of curves in diverse places suggests something else is at work. The large numbers of asymptomatic cases estimated by various antibody studies seems to indicate the virus is more contagious and less deadly
and that a large percentage of people have some kind of preexisting immunity.

You won't know if this is all working as planned, until 2 weeks AFTER the "cases per day" level out at some kind of minimum (compared to how it was a month ago). Because it takes 2 weeks for the virus to incubate into sickness, and the sickness itself can last up to 2 weeks before someone dies from it. People don't just catch it and die the next day. It isn't that neat and tidy or convenient for number-crunchers.

The death rate reduction, in other words, is the culmination of efforts during the shut-down UP TO TWO WEEKS AGO. At that point, the state started re-opening and loosening restrictions. We will see how well that's working in the next two weeks. Not at the present time. If fewer people die in the next two weeks, than they did between 2 weeks ago and 1 month ago, then we'll know we're on to a positive trend.

Yes, everybody knows that deaths lag cases by a few weeks, that's why I selected a graph with daily confirmed deaths. Some of the countries in Europe started opening a month ago, and Sweden never really closed. All show a similar curve going downward.

We won't know until well after that. Lockdown was only undertaken to flatten the curve so that hospitals could cope. Once lockdown restrictions are eased, cases will rise. That doesn't mean we need to go into lockdown again, as hospitals are generally much better equipped now than they were three months ago.

The big question (only answerable many months from now) will be whether countries such as Sweden (that treated its citizens as adults and didn't impose a harsh lockdown) will have a lower overall death rate and a quicker reduction to virtually no new infections than nanny states that over-reacted and are still reluctant to face the fact that hiding away is merely going to delay any recovery.

I think common sense makes the statistics look worthless. In our home state, the spread is worse in factories, medical personnel and the elderly who have been contaminated by visitors and caretakers and fellow residents. It all speaks volumes to person to person spread. Isolation worked.

Yes, a similar curve. But the Y-Axis can be misleading. The range goes from 1 death per to 10! THAT IS A HUGE DIFFERENCE. So, the graph is interesting - but the conclusion drawn from is not accurate.

I used that graph because it adjusted for population in countries. Here is another graph plotting daily total confirmed deaths in USA vs Europe. Europe has more people than us and peaked earlier, but you see the same shape in the curves over the same period of time. Deaths rise quickly and then taper off. Doesn't change my conclusion that something unknown is at work here at all.

Yes, every country was different, hard or soft lockdown, early or late lockdown etc. Here's a good article at Bloomberg, discussing this.

With governments across Europe reopening their economies for business, it’s a good moment to look back on the different paths taken to control Covid-19 outbreaks to try to see how effective they were.

Some — above all Italy and Spain — enforced prolonged and strict lockdowns after infections took off. Others — especially Sweden — preferred a much more relaxed approach. Portugal and Greece chose to close down while cases were relatively low. France and the U.K. took longer before deciding to impose the most restrictive measures.

But, as our next chart shows, there’s little correlation between the severity of a nation’s restrictions and whether it managed to curb excess fatalities — a measure that looks at the overall number of deaths compared with normal trends.

A lockdown is not the only thing to consider though. Most that died from Covid-19 seem to have underlying conditions, of which obesity is a major one. Coronavirus risk: 90% of patients had underlying conditions (https://www.usatoday.com/in-depth/news/2020/04/15/coronavirus-risk-90-patients-had-underlying-conditions/2962721001/) Another important stat to take into account could then be the different rates of obesity in USA (36.2%, 12th highest in the world) vs Sweden (20.6%, 97th from the top).

Let us know when you think the research is on time. Why do you think the CDC just drastically reduced the death rates for this virus? Why did they say asymptomatic cases are at least 35% of the total? Why do asymptomatic people never get sick? Why do death total rise quickly and then fall off in every country?

I don't know if I am immune since I haven't had an antibody test yet. So I continue staying away from people inside buildings. I'm in a high risk group. This doesn't prevent me from considering that the whole worldwide lockdown was an error since 80% or more of deaths are from nursing homes and old people with pre existing health problems. A policy of just isolating seniors and strict rules, PPE for all nursing home staff etc would have saved more lives and allowed younger people to keep working with some precautions and not crash the economy.

I doubt anyone even still reading this thread, but gotta say it anyway. IT WAS THE ANNUAL FLU. It killed a lot of people and is a true tragedy for those families and friends. Let me make that point with a few examples: (1) Just two years ago the US lost 81,000 plus to the annual flu. (2) If not for the gross inflation of this year's deaths we would be under that! (2) Look up the on line CDC instructions for death certificates. They clearly state if it is even possible that the victim had corona virus, count it. No test or autopsy required! (3) Hospitals are struggling and will be paid $19,000 per Covid-19 classification admission. They are capped at $6,000 for other admissions....which code would you use? (4) Look at US numbers versus world-wide. Do you really believe we have 30% of all world wide deaths?

Relative to total population the infection rate in Sweden (0.3%) was lower than in the US (0.5%). Also, relative to total population the death rate in Sweden (0.04%) was 33% higher than the US (0.03%).

Yes, I fully realize there are myriad factors that will enter the picture that haven't yet been considered such as severity of the lockdown, face covering, reporting of asymptomatic cases, etc. In time the important contributing factors will need to be taken into account for a more accurate analysis and assessment regarding the effectiveness of each nation's response - what worked and what didn't work.

Hindsight is always 20/20. We still don't know nearly enough about this virus but we know a whole lot more than we did when the various types of lockdowns began. The longer people, especially vulnerable people, self-isolate, the better the chance that when/if they eventually DO get infected, enough will be known to allow for much more effective treatment.

This is a graph of Covid 19 deaths per million population of the USA and various countries in Europe. It shows that the pandemic has followed a similar curve in these countries, with deaths rising rapidly, and then slowly going down over a period of 60-80 days.

84221

A recent study by an Israeli mathematician proposed that the virus follows a similar curve in most counties, rising up and then going down over a period of 70 days. He doesn't think lockdowns have much effect.

Two recent scientific papers have proposed that their may be some preexisting immunity to covid 19 through previous exposure to other coronaviruses like the common cold.

Using diverse assays for detection of antibodies reactive with the SARS-CoV-2 Spike (S) glycoprotein, we demonstrate the presence of pre-existing immunity in uninfected and unexposed humans to the new coronavirus.

All good and well for 70 days. HOWEVER! There are many more days to come.

Hindsight is always 20/20. We still don't know nearly enough about this virus but we know a whole lot more than we did when the various types of lockdowns began. The longer people, especially vulnerable people, self-isolate, the better the chance that when/if they eventually DO get infected, enough will be known to allow for much more effective treatment. Seems worth the wait and inconvenience to me.

Don't know if you are "old" (over 55) or vulnerable, but if I were U, I'd volunteer to wait and accept any inconvenience to me.

The person I responded to had measured Sweden (no lockdown) against their immediate neighbors that did lockdown and fared much better. Compare like to like. Comparing Sweden to the USA is ,IMHO, like comparing NYC to some tiny town in the mid-west.

NO, you are not comparing like to like. Just because countries are neighbors does not mean they were seeded with the same amount of virus carriers. The coronavirus spread globally by travelers, and each country does not get an equal dose.

For instance, the five worst hit in terms of deaths per million European countries are Spain, Italy, France, UK, and Belgium are also some of the most visited countries in the world, except for Belgium, not sure why they got hit so hard. So they got seeded with lots of virus carrying travelers.

Sweden gets 50% more visitors than Norway and 200% more visitors than Finland, so it's obvious they got more travelers with virus than those countries that so many people like to use to "debunk" Sweden's strategy. And comparing Sweden to countries halfway around the world like South Korea and New Zealand is insane, the virus mutated as it traveled and the most contagious strain developed in Europe, which then seeded New York City and then the rest of the USA.

So if you want to compare "similar countries" in Europe to Sweden, you might pick Belgium and Ireland, which have similar travel levels to Sweden. Belgium has a little more, Ireland a little less.

Belgium 794 deaths per million
Sweden 388 deaths per million
Ireland 322 deaths per million

Also, if we do have a second wave, Sweden will have reached herd immunity while other countries in Europe that locked down will see their deaths go up. The only thing that stops a virus is herd immunity or a effective vaccine.

But their immediate neighbors did lock down, and had a lot less cases and deaths.
Germany, Austria, New Zealand, Australia etc. locked down early, and compared to many, had far lower instances of the virus, and minimal deaths per head of population.
Here in UK our 'experts' dithered over lockdown or herd immunity, and look what that did for us, and our hospitals were not overwhelmed either.
The curve may be nearly the same, but the numbers show that early lockdown reduced cases substancially.

I did a quick analysis myself the other day because I had been coming across reports that social distancing may not be effective. So I looked at death rates in Sweden, which hasn't locked down, and compared them with Sweden's Scandinavian neighbors. I concluded that social distancing may indeed be worthwhile. If this analysis is flawed, I'm all ears.

Population / Number of Covid deaths / Deaths per capita

Norway - 5.32M / 235 / .000044

Sweden - 9.96M / 3871/ .00039

Finland - 5.52M / 306/ .000055

Denmark - 5.62M / 561/ .00001

I doubt anyone even still reading this thread, but gotta say it anyway. IT WAS THE ANNUAL FLU. It killed a lot of people and is a true tragedy for those families and friends. Let me make that point with a few examples: (1) Just two years ago the US lost 81,000 plus to the annual flu. (2) If not for the gross inflation of this year's deaths we would be under that! (2) Look up the on line CDC instructions for death certificates. They clearly state if it is even possible that the victim had corona virus, count it. No test or autopsy required! (3) Hospitals are struggling and will be paid $19,000 per Covid-19 classification admission. They are capped at $6,000 for other admissions....which code would you use? (4) Look at US numbers versus world-wide. Do you really believe we have 30% of all world wide deaths?

Sir? Welcome back! I know you're confused, but you've been asleep for 2 months and things have changed. (Somebody must have left the tv on an 'alternate facts' channel all that time and you've been dreaming...) :1rotfl:

Thanks GoodLife. I'm sure your analysis has merit regarding travel. I saw it after I posted my Scandinavian death rates.

I remember from doing regressions in statistics class that you can never explain cause by one variable only (social distancing in this case). After I did my calculations, I wondered what other variables might be at play.

Travel is certainly one of them. There are probably others, e.g., older population, a population with more co-morbidity, mass transport, population density, etc.

Yes 100s of variables at play, it's why simple calculations of statistics comparing countries don't tell the whole story.

I was appropriately responding to someone else's comment. Secondly, your comparison is absurd, but you have every right to make it. Thirdly, here are the numbers you suggest regarding the effect of no lockdown in Sweden.
Death rate per 1 million in population:
Sweden - 3213
Denmark - 1939
Norway - 1554
Finland - 1188

I apologize. Some where we have ended up at cross purposes.
My original post was in regard to the comparing Sweden against US covid numbers as a justification for "no lockdown". I was in support of the person comparing Sweden with its neighbors as being more appropriate and meaningful than than a comparison between Sweden and the US. The numbers shown above in your quote, I believe, show that the "lockdown" was successful in reducing the number of potential fatalities significantly.
I stand by my opinion of comparing "like with like" in order to get a more realistic picture of current covid conditions. And, I sincerely thank you for pointing out to me that I don't always make myself clear.
Hopefully I'll do better next time.

Always willing to learn.
I accept the comparing of Belgium, Sweden, Ireland as reasonable based on the points you made. In the middle of your post, remarking on high travelled European countries, you inserted the statement "don't know why they got hit so hard" in regard to Belgium. I don't think anyone does, yet. In the comparing the death rates, you said," Belgium a little more". Using the numbers you provided it was more than double. Personally I consider that substantial. More research required to find the reason. And Ireland a little less. Again, more research required to discover contributing and mitigating factors.
Since we are all still in the learning phase, please forgive my poor communication skills. I, like most, are trying to learn while we do the best we can to protect ourselves and loved ones.

I hate to put a damper on all those that know so much about curves and stat. But we are in an area that has older people who should just think about their health first and talk to their doctor. You only can die once.
