⚠️TWO DIFFERENT #COVID19 PANDEMICS—Many think with cases dropping that pandemic is nearly over. But truth is, there are now 2 different #SARSCoV2 pandemics diverging—old strain is waning, while the more contagious #B117 strain is dominating. We will be soon slammed very hard. 🧵
2) Here is what is really going to happen... most countries are having a gentle case decline with R(e) currently around 0.9. But this is deceiving. The #B117 is still relatively rare so far, so the R is being influenced mostly by the old common variant. But not for long...
3) Here is what is going to happen... currently R is ~0.9 in many places, but with the more infectious #B117, the R will jump 50% approximately. And it is inevitable (all CDC and Danish models say this) that B117 will take over as the reigning dominant variant soon...
4) and when that happens, what worked before to keep the pandemic contained at R of 0.9 will no longer work. Here is the model for Alberta, 🇨🇦 by @GosiaGasperoPhD. The B117 dotted red line will soon dominate and drive a new surge in latter half of March and April.
5) And Denmark 🇩🇰 CDC has found the same thing. I GQR works now for keeping R around 0.9 or even 0.8, will absolutely not work anymore once #B117 variant takes over. Forget about it. We will be hit hard. But there is a way—if we suppress R to 0.7 or less.

All you need to know about COVID19
FACTS NOT FEAR
Covid 19 is a disease caused by the SARS-CoV-2 virus. SARS-CoV-2 is one of 7 coronaviruses known to man. 1/n
The pandemic is real. Excess deaths were observed in many countries. Not all countries were affected in the same way due to pre-existing immunity, the health status of the population and demographics (the proportion of elderly in the population) 2/n
https://t.co/65elPq3gp5
COVID 19 presents a high risk for the very few and negligible risk for the many.
The infection fatality rate in different age groups:
<19 y, IFR= 0.003%
20-49 y: IFR= 0.02%
50-69 y: 0.5%
>70y, IFR=
Not everybody is susceptible to the virus. If reinfected, pre-existing immunity from related viruses gives protection from developing the disease or from developing serious symptoms.
4/n
“The evidence that a subset of people has a cross-reactive T cell repertoire through exposure to related coronaviruses is
