The United States is not currently experiencing an influenza pandemic.
It is impossible to predict when the next pandemic will occur or its impact. There are ongoing efforts by the Federal Government to monitor and assess pandemic threats and prepare for an influenza pandemic.
Novel influenza A viruses with pandemic potential include Asian lineage avian influenza A (H5N1) and (H7N9) viruses. These viruses have all been
evaluated using the
Influenza Risk Assessment Tool (IRAT) to assess their potential pandemic risk.
