National Health Surveillance

Tanzania’s health, on open data.

Every figure here is real and public: national disease burden, immunisation and survival, compiled from the World Bank, WHO, UNICEF and the UN, and refreshed automatically as new estimates publish. When THOSSentinel is operating it layers facility-level, real-time syndromic signals on top of this national picture, on the 7-1-7 standard.

Live from open data · refreshed 14 Oct 2026 · auto-updates as new national estimates are published. No simulated case data.

The WHO herd-immunity threshold for measles is ~95%. A dip below it is exactly the kind of gap a live surveillance layer should catch early.

The surveillance footprint

170 districts · 26 regions: where THOSSentinel streams facility signals when live
Detect · 7 days
Open data tells us the national trend once a year. THOSSentinel surfaces a syndromic signal from facility encounters within days of it rising.
Report · 1 day
Signals reach the regional and national command view within a day, with the case denominator attached: not a paper return months later.
Respond · 7 days
Alerts route to response teams and the clock is visible and auditable, from first signal to action, on the 7-1-7 standard.

National indicators via the World Bank Open Data API, which compiles the WHO Global Malaria Programme, WHO Global TB Programme, UNAIDS, the UN Inter-agency Group for Child Mortality Estimation, the WHO/UNICEF/UNFPA Maternal Mortality Estimation Inter-agency Group, and WHO/UNICEF immunisation estimates. Indicators are national annual estimates: the finest-grained health data Tanzania publishes openly: fetched server-side and cached with a daily refresh; a cited baseline guarantees accuracy when a refresh is unavailable. The 7-1-7 timeliness standard is from Resolve to Save Lives; district geometry is geoBoundaries ADM2 (ODbL 1.0). Facility-level, real-time syndromic surveillance is provided by THOSSentinel once operational. © 2026 Laetoli (T) Limited.
