Provisional data. Reported case counts for the most recent weeks are provisional and subject to revision by CDC as more reports come in.

Reported case trend

There isn't enough reported data in this period to summarize a trend.

Reported cases by state

No states reported cases in this dataset for the selected period.

Case-level state data unavailable

CDC's weekly surveillance reports aren't currently linked to individual states in Public Health Trace's data (a known data-pipeline gap, not a lack of real activity). The map below, built from individual reported outbreak investigations instead, is a real, working substitute for state-level context on this disease.

Historical outbreaks by state

A map shading each state by the number of historical outbreak investigations linked to this disease.

Shading reflects state-level totals only, as published by the source. It does not imply county-level or point-level precision.
