Partitioning Social and Spatial Drivers of Infection Risk
Ecology and Evolution, Volume 15, Issue 11, November 2025.Contact rates drive disease spread, yet are often oversimplified as uniform across individuals. Using data on Mastomys natalensis, we show that exposure to Morogoro virus is linked to spatial overlap with infected conspecifics, but not overall overlap, and that direct contact occurs with only a few individuals despite broad home range overlap ...
