Children with EV-D68 (2014) and H1N1 influenza (2009-2010) virus admitted to the ICU at Children’s Hospital Colorado by date of illness onset.

y axis is number of children admitted to the ICU, x-axis is CDC week; black line represents children with EV-D68 and dotted line represents children with H1N1 influenza.

The CDC week is the week of the epidemiologic year for which the National Notifiable Diseases Surveillance System (NNDSS) disease report is assigned by the reporting local or state health department for the purposes of disease incidence reporting and publishing. Values for CDC week range from 1 to 53, although most years consist of 52 weeks.
