Ivermectin-based mass drug administration (MDA) trials have led to reductions in scabies and impetigo prevalence. The World Scabies Program supported ministries of health with national scabies MDA campaigns in Solomon Islands (two annual rounds, 2022–2024) and Fiji (one round, 2022). Here we conducted population-based national prevalence surveys before and after MDA in both countries to assess scabies and impetigo prevalence. We compared scabies and impetigo prevalence before MDA with the prevalence 6 to 12 months after. Over 9,000 participants were surveyed at each time point. In Solomon Islands, following two MDA rounds, scabies prevalence decreased from 23.2% to 3.9% while impetigo prevalence decreased from 9.2% to 1.6%. In Fiji, scabies prevalence decreased from 6.2% to 3.4% and that of impetigo decreased from 4.3% to 1.2%. We observed substantial reductions in the prevalence of scabies and impetigo following MDA in both countries, providing evidence to support similar large-scale scabies interventions.</p>
