Many mosquito-borne pathogens that cause disease in humans, like dengue, are transmitted between humans. However, there are at least 12 mosquito-borne viruses that are transmitted between other animals, for which humans are incidentally infected. These viruses are difficult to control; human vaccination alone cannot eliminate them. Furthermore, because zoonotic mosquito-borne viruses are usually transmitted by multiple host and vector species, they can be present across a range of ecological contexts. In turn, ecological context influences transmission dynamics and risk to humans. The ability to target control within ecological contexts that present sources of onward transmission should increase impact. I will discuss three broad themes of importance for identifying sources of transmission for this group of viruses: heterogeneity, scale, and noise. With respect to these themes, I will highlight current research gaps in the modelling literature and give specific examples from two new projects which aim to address these gaps by integrating empirical studies and modelling for Japanese encephalitis and Rift Valley fever.
