We studied the interactions between hosts, vectors and the environment during a zoonotic yellow fever outbreak at the urban–forest edges of metropolitan São Paulo. Our analyses indicate that a single introduction drove most infections; its high transmission potential (R0 ≈ 8.2) led to local extinction of the resident howler monkey population within around 46 days.
