The record
Written from the 1 report below. Nothing here is unsourced.
- The Tamil Nadu Health Department released dengue data for 2023, 2024, and 2025 that show higher infection numbers than the national figures published by the National Centre for Vector Borne Diseases Control.
- State officials state the discrepancy arises because the national data only includes cases confirmed by NS1 and IgM tests, while the state dataset includes results from rapid diagnostic tests.
- Both sets of data record the same number of deaths for each year.
- This distinction helps the state better understand and manage local epidemic situations.
What to watch next
- Potential impact on national dengue reporting standards
- Continued comparison of local vs national disease surveillance datasets
