Global malaria elimination efforts are threatened by human population travel that facilitates the movement of parasites across borders. Mudzi, a border-located district in Zimbabwe, is characterised by persistent malaria transmission despite a high-performing indoor residual spraying program. No study has been conducted to document the contribution of cross-border movement to the malaria burden in the district. Furthermore, the standard malaria patient registers did not capture history of cross-border movement among cases presenting for treatment. We conducted this study using a newly developed tool that captured cross-border movement among cases with a malaria-positive RDT test at five (5) health facilities and the community level. Microsoft Excel was used to generate frequencies and proportions. A total of 619 malaria cases were recorded at five (5) health facilities. The majority of cases were females (53.47%). Only 101/619 (16.32%) malaria cases reported a history of cross-border movement. The largest proportion (96%) of cases with a reported history of cross-border movement were aged 10–49 years. The highest proportion of cases with a history of cross-border movement was identified at facilities located near the border. Health facilities were the major source of treatment, 522(84.33%), compared to community-based treatment. Analysis revealed that only a minority of cases were residents of Mozambique, 49(7.92%).
