Tanzania is stepping up disease surveillance along informal border routes in Songwe Region to close gaps that could allow outbreaks to spread undetected.
The Ministry of Health, through its Preventive Services Department, is working with the International Organization for Migration (IOM) to assess informal crossing points identified in Momba and Ileje districts and strengthen health monitoring around the Tunduma and Isongole border areas.
The exercise, running from September 13 to 18, 2026, is also strengthening the capacity of health workers to detect, report and respond to suspected disease outbreaks at the border.
The move is particularly important because people who cross borders through unofficial routes may bypass established health screening points, making it harder for authorities to detect potential health threats early.
As part of the exercise, the authorities are receiving a temporary health screening building at the Isongole border post.
The facility will increase the space and capacity available for screening travellers and identifying suspected cases before they pose a wider risk to communities.
The joint assessment is also intended to help authorities map areas considered vulnerable to health threats, improve surveillance and reporting systems and extend prevention measures to communities around informal crossing points.
For residents in border communities, stronger surveillance could mean earlier detection of infectious diseases and faster intervention before outbreaks reach schools, markets, health facilities and other densely populated areas.
The exercise will also involve strengthening coordination between health authorities and other stakeholders working around the borders, recognising that effective disease control requires information to move quickly between communities and authorities.
The Government has increasingly emphasised preparedness for health emergencies from the community level to border points, with early detection and rapid response forming a key part of that approach.
The partnership with IOM is therefore aimed not only at improving screening at formal border posts but also at addressing surveillance gaps created by movement through informal routes.
Health authorities say the approach is necessary because diseases do not respect national boundaries, making early warning systems, cross-border cooperation and rapid response critical to protecting communities.
