Forgive me, for I am about to Bayes. Lesson: Don't trust intuition, for even simple prior+likelihood scenarios defy it. Four examples below, each producing radically different posteriors. Can you guess what each does? Revealed in next tweet >>

Our new study modelling the urgent need for #naloxone in the US. Using a #Bayesian model we developed for BC we estimated the probability of its use during a witnessed overdose. naloxoneneededtosave.org provides estimates for each state @DanCoombsUBC @TraciCGreen1
NEW—Naloxone: substantial increase in life-saving #opioid overdose intervention urgently needed in almost every U.S. state, finds study in @TheLancetPH. hubs.li/Q013Y3Cl0

Our team @CDCofBC & @ubcspph in #Vancouver is recruiting a quantitative #epidemiologist with focus on #COVID-19 and a #postdoc infectious disease #modelling to work with COVID-19 response team @CDCofBC. #epitwitter. DM me if interested. #BigData #YVRjobs @UBCmedicine

Pleased our work on the use of mixture density networks for emulation in epidemiology has recently been published in @PLOSCompBiol. Check it out: doi.org/10.1371/journal.pcbi… @MikeAIrvine @DeirdreHoll @QuentinCAUDRON

Yesterday's talk for those who missed it, or don't have Netflix: Real-time modelling of the 2020 coronavirus epidemic. youtu.be/dLVLEZMzIOk via @YouTube. Shoutout to @UBC cosmologist Douglas Scott for the invitation to speak in the physics colloquium.

Lots of talk at the moment surrounding the R0. I recently created an app to explore the concept for educational purposes only: sempwn.github.io/vaccine-dyn…

Great to see this published before I move from @CDCofBC Thanks to the whole team for getting this one out!

Overdose deaths would be 2.5 times as high without emergency harm reduction in BC. “This is among the first evidence to show that a combination of harm reduction and treatment interventions saves lives,” says #UBC researcher Mike Irvine ow.ly/43v850uxo0i

Rapid expansion of B.C. harm reduction services likely saved about 3,000 lives, province's Centre for Disease Control says. Study finds overdose death rate between April 2017 and December 2018 could have been as much as 2.5 times higher. Background: cbc.ca/1.5156279

Visualization of mathematical modelling can help in public understanding of health risks.
An average person with the measles is likely to infect 12 to 18 others in an unvaccinated population. So what starts as an isolated case can rapidly become a full-blown epidemic. 53eig.ht/2scZHrQ
