(KLZA)--Flu season is in full swing, and as of Wednesday, Kansas is the sickest state in the nation.

The company Kinsa, who makes thermometers, records daily data to see where flu-like symptoms are spreading in real time. They say based on Wednesday's data, over 1% of Kansas' population - about 29,000 people -are sick.

Those people are experiencing high temperatures and flu-like symptoms, such as cough, chills and sore throats.

 Kinsa also says other than Wednesday, the Sunflower State reached peak sickness levels on Saturday, January 13th.
