We conducted a discrete choice experim…

  • Disentangling the roles of different vector species during a malaria resurgence in Eastern Uganda

    Open AccessMax McClure, Ambrose Oruni et al.ARTICLEPLOS Global Public Health2025

    In 2021–23, a resurgence of malaria occurred in the Tororo District of Uganda following a change in formulations used for indoor residual spraying of insecticide (IRS). Prior analyses showed that this increase was temporally associated with the replacement of Anopheles gambiae sensu lato by An. funestus as the dominant local vector. To investigate this association, we used data from a cohort of 422 children in 94 households from 2021-2023 in Toro…
