Hello Canada! πŸ‡¨πŸ‡¦

A few things you might not know about the pandemic...
🧡

1/
πŸ‡¨πŸ‡¦ Did you know that 2022 was the deadliest year of the pandemic in Canada?

2/
πŸ‡¨πŸ‡¦ Did you know that Canada recently passed 50,000 COVID deaths?

3/
πŸ‡¨πŸ‡¦ Did you know that more Canadians have died of COVID than died in World War II?

(πŸ‡ΊπŸ‡Έ Also, did you know that more of our American neighbours have died of COVID than dies in combat in every war they've fought since 1775?)

πŸ‡¨πŸ‡¦ Did you know that the *lowest* number of COVID patients in hospital has been increasing through 5 waves of Omicron and that the troughs have all been higher than the *peak* of the Delta wave?

πŸ‡¨πŸ‡¦ Did you know that summer 2022 had twice as many deaths as summer 2021?

6/ There were twice as many de...Since summer 2022, wastewat...
πŸ‡¨πŸ‡¦ Did you know that the main issue with Omicron variants is no longer "tsunamis" caused by individual variants, but rising sea level with high and low tide? This imposes sustained pressure on the healthcare system.

πŸ‡¨πŸ‡¦ Did you know that 15% of Canadians infected with COVID (1.4 million people) report long-term symptoms?

πŸ‡¨πŸ‡¦ Did you know that there are now more than 700 Omicron subvariants, and that many of them can escape prior immunity and are resistant to available treatments?

πŸ‡¨πŸ‡¦ Did you know that mitigation measures like high-quality (N95) masks worn properly, ventilation, air filtration, and avoiding high risk contact are all variant-proof?

Quick note about the not-low lows of hospitalizations since Omicron. Same pattern happening in various places (New York, UK, France, Denmark, etc.).

The best we get now is *relative* lows. Here are numbers of hospital patients with COVID in Canada. It's as low as it has been since the first Omicron wave (early 2022), on par with the relative lull of mid-summer 2023. But still much higher than summer 2020 and summer 2021. Hospitalizations in Canada
*Maybe* it will continue to drop as thr weather warms and if there are no new major variants that displace JN.1* in the meantime (fingers crossed, and wastewater signal is low), but the reality is that the baseline has never come back down in Canada post-Omicron.
Relative lows do not mean no risk, they mean less risk. If you've been putting off doing things while cases were higher, a relative low is a better (but again, not risk-free) time to do them than during a relative high, obviously.

Let's be clear about what happened here. 🧡

1. Israeli real estate companies held Jews-only events to sell land in Israel and contested (Jerusalem) or occupied (West Bank) territories in Palestine.

1/
Note that some of the events are taking place in synagogues and some include properties that are within the illegally occupied West Bank. Other events have been held at public venues.

2/

2. Politicians preemptively labelled planned protests of events being held at synagogues as antisemitic.

Measles touted as an example of the effectiveness of working out one's immune system muscle.

A few reminders about measles...

🧡 "For some bugs, once you've fought it once, your muscles are so strong against it they may never need another work out to fend it off (e.g. measles, smallpox"
Measles has been known for 1,000 years and it still hasn't evolved to be benign.

pubmed.ncbi.nlm.nih.gov/36414136/
Measles can cause "immune amnesia", wiping out immunity to other pathogens.

(This was discovered only a few years ago. The measles virus was identified in 1954 and the disease has been described since the 9th century.)

Now that Pirola clan (BA.2.86 and descendants, most notably JN.1*) is the dominant variant lineage globally, the question arises as to whether it might undergo recombination with earlier XBB lineages.

Yep. Already has.

🧡
So far...

Pirola x Arcturus:
XDK = JN.1.1.1 x XBB.1.16.11

Pirola x Eris:
XDD = JN.1 x EG.5.1.1
XDS = JN.3.2.1 x EG.5.1.3

Pirola x Kraken:
XDN = JN.1. x JD.1*
XDR = JN.1.1 x JD.1.1.1

Pirola x Hyperion:
XDP = JN.1.4 x FL.15
Reminder of how recombination occurs.

Here are some excellent threads about more highly divergent BA.2 lineage variants showing up after having evolved within a single host with a chronic infection. Within-host evolution is going to be an increasingly important issue.

Whoa. Japan. Small samples, but obviously do not want an HK.3 wave on top of JN.1 or even just a sustained high baseline.

Reminder:

JN.1 (Pirola clan) = BA.2.86.1.1

HK.3 (Eris + FLip) = EG.5.1.1.3
