LOUISVILLE, Ky. (AP) - Health officials and federal data say flu activity in a Kentucky city is on the rise during the 2018-19 season.

Louisville Metro Department of Public Health and Wellness spokesman Dave Langdon tells the Courier Journal that Jefferson County had 570 flu cases reported during the last week of December, compared to 202 cases the week before and 36 cases two weeks prior. Langdon urged people who haven’t gotten a flu shot to get one.

Centers for Disease Control and Prevention data shows that Kentucky is one of nine states that experienced high flu activity for the week ending Dec. 22. Other states included Alabama and Colorado.

The CDC says flu activity historically peaks in February in the United States, though different seasons have different peaks and the flu virus actually circulates year-round.
