The spread of flu in the 15-county Louisville and Southern Indiana area slowed last week with a 26% drop in new diagnoses
Norton Healthcare providers diagnosed 26% fewer flu cases in the 15-county Louisville and Southern Indiana area last week, with influenza B accounting for nearly 64% of the confirmed cases among children.
Norton Healthcare providers confirmed 783 new cases last week through laboratory tests. In addition, Norton Healthcare providers diagnosed 259 cases based on symptoms and did not seek laboratory confirmation.
Influenza B, which typically emerges late in the flu season and can be more severe in children, got an early start this season and accounts for about half of all confirmed cases so far.
Preliminary data suggests this year’s flu shot has been 45% effective, the Centers for Disease Control and Prevention reported Thursday. In previous seasons, the influenza vaccine has been between 40% and 60% effective.
Areas most heavily affected this season have been in western and southern Louisville and in Bullitt County. In the past month, areas of western and southern Louisville have shown the biggest drop in new cases.
Louisville Metro health officials reported 333 confirmed cases within Jefferson County, down 42% from the week before.
A Flu Shot Still Can Help
There’s still time to get a flu shot. While it takes about two weeks for the shot to protect you, it can lessen the severity of symptoms if you catch the virus.

Flu Prevention Tips
- Avoid being face to face with a sick person. If possible, spend as little time as possible in close contact with a sick person.
- When holding sick children, place their chin on your shoulder so they will not cough in your face.
- Wash your hands often, as soon as you’ve had contact with a sick person and after handling their tissues or laundry.
- If soap and water are not available, use an alcohol-based hand sanitizer.
