Calgary Zone Covid-19 cases update & variants Feb 28, 2021

Calgary Zone Total Variant Cases Feb 28 2021.jpg

The first UK B.1.1.7 variant was detected in Alberta in Dec. 24 from a Dec. 15 test and made public Dec 28.

 

The first South African N501Y.V2 variant case in Canada was detected January 8 in Alberta. 

 

All cases were from travelers returning from out of country.  In other words, we imported them.  Canada has not had a proper lock down since covid19 started, and only recently took responsibility for incoming flights.

 

Feb 1

- Calgary zone student UK variant (child of a returning traveler)

 

Feb 3

- Combined COVID mutations are discovered in the UK variant carrying an additional gene mutation seen in a South African variant.

 

Feb 4

- two more UK variant cases in Calgary zone schools (travel related), total of 5 students

 

Feb 17

B.1.429 variant that originated in California and the UK variant have reportedly merged and are being monitored.  This occurs when someone is infected with two strains at the same time.   

- The recombinant carries a mutation from the Kent variant - known as B.1.1.7 - which makes the UK virus more transmissible.

- It also carries another mutation from the California variant - known as B.1.429 - which can produce resistance to antibodies.

I think I’m missing the day by day numbers and lack the time to dig for them, however there is enough to start a trend chart.  Pleases forward links to any data I’m missing and I will update – specify date, variant # in Calgary zone, and link.  

I will use Alberta Health’s published variant data going forward as I have been for regular cases here https://www.alberta.ca/covid-19-alberta-data.aspx

I find it strange Alberta Health Services reports Calgary case #'s for the day prior "(ex. Table updated March 1. Numbers accurate as of end of day Feb. 28.) yet for Variant cases it appears as same day (ex. Table updated March 1.)

If they do not know same day cases, how could they know the same day variants cases?

I'd ask but they rarely answer my questions and failed to answer everything I asked last year, so I'll just adjust numbers by a day if needed.  It's still a good representation even if off by 24 hours, and like the ebola trend charts I created, these will be the only ones for Calgary zone variants also unless AB health creates some.  They took several months before providing zones info in 2020.

My Thoughts & Question:

Also, it's getting close to a year, will Canada have it's first real lock down at some point?  Flight traffic - which imported the UK variant - is only being addressed as of recently.

There is no shortage of countries that have taken responsibility and successfully controlled and eliminated the virus, allowing their people to be fairly free again. I can think of 6-8 countries off the top of my head (this article says 30 https://coronavirus.nautil.us/which-countries-have-beaten-covid-19).

Is a short lock down actually less expensive than maintaining virus spread as we’ve been doing in Canada?

I requested the cost of these short lock downs to compare with maintaining the spread as we've done for a year.  

I believe an actual lock down would be a cheaper option and healthier for the both the economy and people’s mental health than what Canada has been doing.  We have enough data from countries that have done this to calculate it, or provide reasonable estimates.

I sent a tweet Nov 3 here https://twitter.com/RyanCartiers/status/1323646488895844352 feel free to retweet if you’ve also curious.

Calgary zone covid19 case update to July 31, 2020

Calgary zone covid19 cases July 31.jpg

Confirmed cases still increasing however recent spike 2 weeks ago seems to have tapered.

Active cases increased for 2 weeks then decreased last week. Mandatory masks start Aug. 1st we’ll see if it has any impact.

Still no proper response from Alberta Health on any questions I’ve asked, they just give me the same link over & over which lacks the information I requested; I also pointed out June 25 the trend chart does not match daily active & confirmed case numbers they published. Here’s the 1st example I sent them:

Alberta Health Reported numbers 2020-07-17.jpg

AHS published 5785 confirmed cases on July 17, the date of this screenshot.

Yet the July 22 trend chart reports

July 17 having 5883 cases.

What accounts for 98 case the difference?

Alberta Health Reported numbers 2020-07-22 1246.jpg
Alberta Health Reported numbers 2020-07-22 1250.jpg

They did not respond to this example. Here’s another: July 30 reports 6470 confirmed cases

20200730 1724 AHS Calgary zone covid19 reported #s.jpg

However the trend chart on August 2 shows a different number of cases on July 30, it says 6499.

What accounts for the 39 case difference?

I noticed the numbers are often different so I’ve done a few screen shot examples to have them account for the difference.

Covid19 Cases Jump in Calgary - July 20 update

(For some reason AHS has stopped reporting weekend #’s also, so they’re averaged over the weekend)

Calgary zone covid19 ACTIVE cases only Jul 20.jpg
