Cattle-related risk factors for malaria in southwest Ethiopia: a cross-sectional study
Abstract Background Despite the low to moderate intensity of malaria transmission present in Ethiopia, malaria is still a leading public health problem. Current vector control interventions, principally long-lasting insecticidal nets and indoor residual spraying, when deployed alone or in combinatio...
