Modelling environmentally transmitted pathogens Many pathogens are able to replicate or survive in abiotic environments. Disease transmission models that include environmental reservoirs and environment-to-host transmission have used a variety of functional forms and modelling frameworks without a clear connection to pathogen ecology or space and time scales. We present a conceptual framework to organize microparasites …

Transmission intervals and COVID control The spread of epidemics is structured by delay distributions, including the now-famous "serial interval" between the symptom-onset times of an infector and an infectee (often conflated with the "generation interval" between infection times). Defining these time distributions clearly, and describing how they relate to each other, and to key parameters …

Vector-borne diseases spread and control: The case of Chikungunya in French overseas territories and consequences for dissemination in mainland territory Dengue, chikungunya and Zika viruses have expanded their geographic range during recent decades and are now considered emerging threats in temperate areas. In particular autochthonous transmissions of chikungunya virus (CHIKV) have regularly been observed in …
