LOUISVILLE, KY (WAVE) - Norton Healthcare officials are seeing a huge jump in positive flu tests, with pediatrician offices reporting more than 100 confirmed cases in just the past week.
By comparison, those same offices had been averaging about two dozen cases per week.
And according to the Kentucky Department for Public Health, the number of laboratory confirmed influenza (flu) cases in Kentucky have spiked in recent weeks, to almost double what they were in November.
Cases of the flu in Kentucky are most common in children ages 1-10, according to the KDPH. In Louisville, the average age of confirmed cases is 36, the Louisville Metro Department of Public Health and Wellness reports. About 57% of confirmed cases are from men, 43% from women in the Louisville metro.
Kentucky is one of 18 states experiencing regional influenza activity, according to the Centers for Disease Control. Jefferson County has the most confirmed cases of the flu in the state, followed by Perry, Oldham, Warren and Barren Counties, according to the KDPH.
The most common type of the flu in Kentucky is the influenza A virus. That’s also the most common flu virus in the country--type A viruses have dominated in the United States since October.
Signs and symptoms of the flu include a (usually high) fever, headache, feeling extremely tired, a dry cough, a stuffy or runny nose and muscle aches. Vomiting, nausea, and diarrhea are also symptoms, more common in children than adults.
