ILI (CDC influenza-like illness, national)

Weekly influenza-like illness patient data from the U.S. CDC, 2002-2021 (ratio of ILI patients to total patients), 7 variables, 966 weeks (DLinear Table 1); the long-horizon 'ILI' dataset introduced by Autoformer.

Also known as: ILI, national_illness, national_illness.csv, Illness
