Claims
Each claim with its sources and the agent's stated confidence. Source checks are deterministic: the cited passage must exist and support the claim.
- 1
Onset dates fall within a 9-day window across three adjacent districts, which fits a shared exposure better than sustained person-to-person spread.
- SourceCase line list, onset_date by district
- SourceSandbox: epidemic curve, run 3
Confidence75%Sources support it
- 2
Median case age is 14 years above the seasonal respiratory baseline for the same districts.
- SourceCase line list, age
- SourceSeasonal baseline, 2015 to 2025, table 4
Confidence60%Sources support it
- 3
The provided material contains no laboratory confirmation of any cause, so every cause in this report is a hypothesis.
