Malaria incidence and prevalence in Vila Assis Brasil (intervention site) and nearby larvicide-untreated localities in northwestern Brazil. The monthly incidence of microscopy-confirmed clinical malaria (P. vivax and P. falciparum infections combined) in Vila Assis Brasil (VAB) and comparison localities between September 2017 and December 2019 is shown as gray (VAB) and black lines (seven comparison localities in the municipality of Cruzeiro do Sul). Prevalence rates measured by microscopy and PCR in VAB before (September 2018) and during (March 2019 and September 2019) the intervention are indicated by red and green diamonds, respectively. Vertical arrows indicate the timing of larvicide treatment, and the light blue area chart indicates the monthly rainfall (mm)
