This page shows the weekly ILI+ reported through EW19 of the 14-15 season. Updates will resume mid-November for the 15-16 season. Use the 'Select week:' slider to select release week and 'Select strain' option panel to specify strain. The larger map shows ILI observations in select cities and the smaller panel at the lower left shows the state-level observations. Hover on a bubble (for cities) or region (for states) to see the observed counts.

For our ILI+ forecasts, see 'Forecasts' tab. Use the option boxes on the right to select influenza strain and geographical location. The top panel shows forecasts for the selected strain and location; the lower panel shows the reported ILI+ for the same strain/location combination for the last four seasons.
