👶🦠 Young kids are sick all the time, but can our models capture that? What if the contact matrices we all use are dramatically under-counting contacts among young children? Check out our latest @anande.bsky.social @loosaraliyen.bsky.social @shauntruelove.bsky.social www.medrxiv.org/content/10.6...

Quantifying infection-relevant contact patterns among young children in childcare settings in the United States
Age is a primary determinant of symptom severity and transmission patterns for many infectious diseases, motivating the use of age-stratified models parameterized by contact matrices. In the United St...

I did one example where students who reported receiving a flu vaccine this season (a question on the pre class survey) were vaccinated in the simulation. And yes I used some network visualizations as well to show both the structure of network and result of epidemic simulations

I have done interactive exercises of infections spreading on networks. Students filled out surveys before class that I used to construct contact networks with different layers, and then simulated epidemics spreading on this network.

👋 Exciting to see so many new accounts with familiar names popping up here the last few days! Looking forward to a new (and hopefully more sane) space to discuss science and public health. If you're also just starting out, check out these great starter packs for infectious disease modeling:
