Great collaboration with Institut Pasteur Madagascar showing how rat and flea dynamics drive plague seasonality, with important implications for control strategies against plague in @pnas.org!
Plague remains a health issue in several parts of the world—especially in Madagascar, where epidemics follow a seasonal pattern. In our new @pnas.org paper, we link that seasonality to rat and flea dynamics and quantify the impact of various control strategies. doi.org/10.1073/pnas...
