I, and a group of colleagues, have been running a training program in quantitative microbial risk assessment (#QMRA) for some years. In 2024, we are doing a “train the trainer” version. For info, and to apply, go to: https://events.anr.msu.edu/event.cfm?eventID=08011DA7182D89CE0DEA0BA06CA6F16D1ECBB7628D3137E6EF12A261DD479F2B

@jmcrookston Another organism that we have analyzed. Some very elegant animal studies were done that we were able to use: https://journals.asm.org/doi/full/10.1128/aem.01190-10

@jmcrookston And yes, we have published dose response curves for influenza.

Independent action hypothesis (IAH), dose response, and ID50 thread 🧵

IAH = idea that each single virion has chance to infect

Dose response curves. Related to the ID50, or infectious dose to make 50% of organisms sick. Measuring how much of a pathogen is needed to cause %age of infection.

A thread about stuff the talking heads don't want you to know.*

(*In fairness they probably don't understand it.)

@aetiology “It’s the dose, stupid”. I seem to need to keep reupping blog posts I did in 2020. https://chaasblog.wordpress.com/2020/05/18/its-the-dose-response-stupid/ #COVID19 #QMRA #riskassessment

@eeyam @novid @PieterPeach Congratulations on the rediscovery of basic concepts of dose response relationships. As I wrote in my blog back in May 2020: https://chaasblog.wordpress.com/2020/05/18/its-the-dose-response-stupid/
