Social + news tracker
Official updates, reliability-screened reporting and verified agency channels—ordered by publication time without disguising a failed feed as fresh news.
West Virginia reports 313 cases
The state total updates Tuesdays and Fridays. County shading preserves the date of its latest official snapshot.
Federal outbreak table checked for new clusters
FDA CORE is monitored for separate Cyclospora investigations, case-count changes, traceback activity and outbreak closures.
Indiana reports 2,069 cases
Indiana publishes a weekday state and county table; retained values are clearly marked when the live parser cannot verify a new table.
15,716 confirmed domestic cases
All U.S. domestic surveillance through Aug 31: 828 hospitalizations across 47 reporting states, plus 11,841+ reports under review.
North Carolina reports 929 cases
North Carolina’s current investigation is tracked separately; the state says its increase does not appear to be the same as the iceberg-lettuce cluster.

Scope warning: Michigan’s outbreak-period reports, CDC’s confirmed domestic surveillance, and the lettuce-linked cluster overlap but are not equivalent populations. Trend figures reflect reporting growth, not necessarily infection growth; backlogs, testing expansion and different definitions can cause sudden jumps.
