Two people have died from the flu in southern Colorado. Both cases were reported in Pueblo County.
The health department said both people were middle-aged adults.
Thirty-eight people in Pueblo County have been hospitalized.
The Pueblo County Sheriff's Office said it is seeing an increase of flu cases in inmates and jail staff members. The health department said the cases in the jail mirror the increase in flu-like illness in the county and throughout Colorado.
Health officials told KKTV 11 News that the H1N1 virus is likely to blame. It is more severe than normal this year.
Health officials also say that even if a vaccinated person still gets the flu, it is likely to be much less severe than if they were not vaccinated.
Health Officials in El Paso County said today that there are no reported deaths because of the flu this season.
