Kentucky's flu season officially launched this week: The state's first confirmed case of the illness was reported in Jessamine County.
The Kentucky Department for Public Health, which announced the flu case Wednesday morning, is urging Kentuckians to get a flu vaccination. Kentucky's flu activity is classified as "sporadic," the lowest level.
Flu vaccinations can be given during any time of the flu season, which can begin as early as October and lasts through May.
For the week ending Oct. 29, the Centers for Disease Control had only sporadic reports of flu nationwide, with the number of cases far below those needed for the signifiers — local, regional and widespread — that it uses when flu cases increase.
Never miss a local story.
The CDC says that its monitoring system indicates geographic spread of the flu, but does not measure the intensity of flu virus activity.
