One of my favourite accounts to follow on Twitter is that of David Fisman (@DFisman). He's an epidemiologist and professor at the University of Toronto. He shares his unfiltered opinions on politics and public health - always an interesting account to follow for information on Covid-19. On top of that, he's sassy, sarcastic, and on Maclean's list of most influential Canadians.

This morning, I read his thread on how long SARS-CoV-2 will be with us. Definitely the best five-minutes I've spent all day.

Give it a read yourself here.

Don't want to read it? You can read my key takeaways instead:

  1. Fisman thinks that SARS-CoV-2 will become a seasonal endemic virus for a long time to come.
  2. As the population acquires immune experience (from exposure to the virus), R (the reproduction number) decreases. As a result, a future resurgence of Covid-19 may be more mild.

But the basic idea is that the pandemic itself seals its own doom by depleting population susceptibility, just as a forest fire ensures its own end by burning up all the fuel.
