RE: The COVID-19 pandemic - tomh009 - 09-14-2020
Speaking of second wave, it's arrived alright. While the US (and a number of other countries) are still trying to control the first wave, the pandemic has returned with a vengeance in a lot of countries that originally got hit much earlier.
Countries like Japan and South Korea got hit again as well, but have wrestled it down a second time, with infections trending the right way.

The waves of a pandemic are interesting, because AFAIK there is nothing about the virus itself which would lead to this effect, I assume it must be driven almost entirely by human behaviour...I'm tempted to try and model this, I am curious about what it is that humans are doing that causes this, because in many (most?) cases, the second spike is far far larger than the initial.
RE: The COVID-19 pandemic - tomh009 - 09-14-2020
I agree very much, it's the humans, not the virus. In some cases (such as Israel) the virus has spread into communities that never had it before. But in most cases it is the relaxation of behaviour that allows the virus to spread again rapidly. An that's the same thing that's happening in selected areas in Ontario, too.
Oh yeah, all the charts are from here:

It could be weather related — more people staying in doors. People letting their guard down. People are getting lazy with social distancing. As I mentioned earlier, I’ve seen some food service not covering their face. There are other reason too, I am sure.

I'd wondered about resurgences... everywhere... and did an analysis as of early Sept.

Africa continues to do well and I should edit my post and mention that.
European countries are mostly not near the early peaks but some are getting there. This virus will do that.

We have a doctor in the house guys!
OK, so not a medical doctor, but interesting none-the-less. I guess I'll need to proofread my spew from now on.

Thanks. One nit I have with the source dataset is that they do use a seven-day moving average rather than the last day -- but their peak value is not based on a seven-day average -- some countries had one-day peaks that were way higher than the surrounding days due to catching up earlier reports. But it looks like it would not be trivial to get that seven-day peak value.

Waterloo Region reported two new cases today (0.1% of the total and 2.7% of the active cases) but added five more for yesterday. Given how often the region updates the previous days' data, it's much better to look at weekly numbers rather than daily. New cases are now averaging 14.8% of active cases over the past seven days. 75 active cases (+7). 58 new cases for the week.
No test data until Friday.
Ontario reported 315 new cases today with a seven-day average of 243, still going up fast. 154 recoveries and two deaths translated to an increase of 159 active cases and a current total of 2,316. A weekly total change of +776 active cases. 28,761 tests for a 1.10% positivity rate. The positivity rate is averaging 0.82% for the past seven days.
The new cases are 0.7% of the total and 13.6% of the number of active cases. New cases averaging 12.6% of actives over the past seven days.
ICU patient count is at 20 (+1).
- 77 cases in Toronto: 2.4 per 100K population
- 61 cases in Ottawa: 6.1 per 100K
- 54 cases in Peel: 5.4 per 100K
- 37 cases in York: 3.4 per 100K
- 24 cases in Durham: 3.7 per 100K
- 10 cases in Windsor-Essex: 2.5 per 100K
- 2 cases in Waterloo: 0.3 per 100K (based on regional reporting)
GTA now up to 182 cases a day, and Ottawa up to 61.

My understanding is that your profession probably helps more people ‘in the background’. We don’t think about it, perhaps don’t even appreciate it, but it makes life a lot better.

I think GTA is 192 -
Either way, outside the GTA, Windsor and Ottawa, we had 52 cases.
Gotta wonder why Ottawa continues to have so many cases. Not good at all.

Ottawa is apparently due to people socializing at private homes without appropriate precautions. Something like two thirds of new cases involve people under the age of 40.

I'd prefer number of hospitalisations or deaths as a better public metric. Too many people under 40 think this wave is overblown because it is "only" bad for older people.
