Linking within-host dynamics to between-host dynamics for microparasites can be really difficult, e.g., Partial Differential Equations are hard to work with. Ruijiao elegantly derived a simplified Ordinary Differential Equation model that is much easier to work with! doi.org/10.1111/1365...

We collect pathogen load data all the time to tell what proportion of hosts are infected and also how infected they are. Our new theory shows that trends in the variance of pathogen load can reveal underlying mechanisms, e.g., what kind of resistance frogs are evolving. doi.org/10.1098/rsif...
Panel A depicts pathogen load increasing over time for an infected host but decreased at all times by constitutive resistance. Inducible resistance reduces pathogen load at high loads while acquired resistance decreases pathogen loads at any time during a reinfection. Panel B shows that evolution of constitutive resistance, over years, leads to lower mean and roughly the same standard deviation of log pathogen load. Panel C shows that evolution of inducible resistance lowers mean and standard deviation. Panel D shows that evolution of acquire resistance lowers mean and increases standard deviation.

Hooray! Kind of... mostly... Hooray? I'll adopt Cherie Briggs' advice that anything besides "We reject this paper forever" is a win.
Gru from Despicable me is detailing his nefarious plan. Stage 1 is "Write an ambitious paper". Stage 2 is "Submit to a fancy journal." Stage 3 is "Get a major revision decision but the revisions are hard." At first, he is excited about Stage 3 then less so when he considers it.

The CDC updated its vaccine page to claim "vaccines do not cause autism" is "not evidence-based" and studies were "ignored." This is an outrage. Decades of research have found no link. This isn't science, it's RFK Jr. using the CDC as propaganda. Children will die because of this.

We know that wildlife provisioning can promote or inhibit infectious disease spread, depending on things like food quality. What about pathogen evolution? Using math with a focus on birdfeeders and house finches, we found that high quality food selects for higher virulence! doi.org/10.1086/738726

Standing host genetic variation typically protects in case of disease invasion, right? Well... Exploring implications of my new paper with @sabarra.bsky.social , a thread (1/5). doi.org/10.1007/s002...
The figure is divided into a left panel titled "Resistance variation" and a right panel titled "Tolerance variation". The left panel shows a frog labeled "Disease-free" with a gold arrow labeled "R0 > 1" and "Invasion" leading to a frog with fungus shown on it labeled "Endemic". There is a purple arrow labeled "Evolution" and "R0<1" leading from the Endemic frog back to the Disease-free frog.

The right panel is labeled "Tolerance variation" and has the same Disease-Free and Endemic frogs. There is a purple arrow labeled "R0<1" and "Failed Invasion" leading from the Disease-free frog and curving back to it. However, there is also a gold arrow that splits off from the purple arrow. The gold arrow is labeled "Evolution" and "R0>1" and leads to the endemic frog.

New paper: We know the minority of hosts hold the majority of macroparasites (aggregation). What about fungal pathogens? Turns out, they are MORE aggregated than macroparasites, lognormally distributed, and the distribution carries signatures of epidemic stage. doi.org/10.1098/rspb...
