New research flags Northern Uganda as high-risk zone for Pig Tapeworm

Clustering of infections within households and villages highlights the role of poor sanitation and pig management practices in sustaining transmission of Taenia solium, according to the study. With nearly one quarter of households in the surveyed areas reporting at least one infected pig, the findings point to a significant and ongoing public health risk, particularly in communities where pork inspection is limited and undercooked pork consumption is common.

Researchers warn that without prompt and coordinated interventions, northern districts of Uganda could continue to serve as a reservoir for the parasite, undermining both national and global control efforts. Taenia solium cysticercosis is included in the World Health Organization’s 2021 to 2030 roadmap for neglected tropical diseases, which calls for targeted action in high transmission areas.

The study supports a One Health approach that integrates improvements in sanitation, pig husbandry, community education, and treatment of both human and animal populations. It also validates the use of geospatial modelling to identify and confirm high risk zones, allowing policymakers to better target resources.

Sustained investment, improved diagnostics, and complementary strategies such as targeted treatment around identified carriers are seen as critical to breaking the cycle of transmission.
