Chicago is seeing a slight decrease in flu activity, but health officials say the dip may be only temporary.
Last week there were 31 patients in hospital intensive care units with the flu, a decrease from 35 the previous week.
Public health officials are getting creative as they reach out to the public with flu information. Chicago's health department is holding a chat on Twitter to answer questions.
Chicago Department of Public Health spokesman Brian Richardson says there's more than enough vaccine to go around, including free flu shots.
The flu vaccine is reformulated each year, and officials say this year's version is a good match to the viruses going around.
Illinois is among the 24 states hardest hit by the flu.
