This dashboard only uses U.S. CDC NNDSS weekly tables. Counts are provisional, assigned by MMWR reporting week, and can lag active local or state investigations. Weekly additions are derived from changes in CDC's cumulative YTD fields because rare-disease rows may update YTD even when the Current week field is blank.
