For the week ending October 22, the proportion of people seeing their health care provider for influenza-like illness (ILI) was 1.3%. This is below the national baseline of 2.2%. All 10 regions reported ILI below their region-specific baseline levels.
New York City, Puerto Rico, and all 50 states experienced minimal ILI activity. The District of Columbia did not have sufficient data to calculate an activity level. ILI activity data indicate the amount of flu-like illness that is occurring in each state.
Widespread flu activity was reported by Guam. Regional influenza activity was reported by Puerto Rico. Local flu activity was reported by one state (Alabama). Sporadic flu activity was reported by the District of Columbia, the US Virgin Islands, and 41 states. No activity was reported by 8 states (Idaho, Illinois, Mississippi, Nebraska, New Hampshire, Rhode Island, Vermont, and West Virginia). Geographic spread data show how many areas within a state or territory are seeing flu activity.
Influenza-associated hospitalization data from the Influenza Hospitalization Surveillance Network (FluSurv-NET) for the 2016-2017 influenza season will be updated weekly starting later this season.
