For weeks, New Mexico has reported the highest percentage of patients experiencing influenzalike illness compared to the rest of the nation.
The CDC defines influenzalike illness, or ILI, as a fever of 100 degrees or greater, along with a cough and/or sore throat. The agency collects data on outpatient visits to healthcare providers for respiratory illness through ILINet. ILI percentages are weighted for state population and compared to baseline levels to assess flu activity. For more information on how the metric is calculated, click here.
For the past four weeks, ILI visits have been declining slightly. Nationwide, 5.36 percent of outpatient visits to a healthcare provider were for flu or other respiratory illnesses in the week ending Dec. 31, down from 6 percent the week prior, according to the CDC. The percentage of ILI visits fell in 40 states and Washington, D.C., was flat in two and increased in eight.
Here is how each state and Washington, D.C., stacked up:
