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
Confidence41%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
Confidence38%Sources only partly support it
- 3
The provided material contains no laboratory confirmation of any cause, so every cause in this report is a hypothesis.
- SourceCase line list, lab_result field
- SourceSponsor data notes
Confidence55%Sources support it
- 4
Severity is concentrated in cases over 60, matching the pattern of most community respiratory clusters in the outbreak archive.
- SourceOutbreak report archive, 214 respiratory reports
- SourceCase line list, outcome
Confidence44%Sources support it
- 5
Linking cases to hospital admission records would separate a severity signal from a reporting artefact.
