A cross-sectional study was conducted in Tete Province, 2019. Data about women aged 15-49 was collected in community households, selected randomly. We used a multivariate logistic regression to estimate adjusted odds ratios (aOR), at 95% confidence interval (CI), to determine malaria complete knowledge associated factors. Malaria knowledge was defined as when a woman responds correctly to five malaria questions about symptoms, transmission, prevention and treatment. We used STATA 6.1 for data analysis.
