Health care professionals are urging people to stay home, drink fluids and rest if they are experiencing flu-like symptoms. According to the Centers for Disease Control and Prevention, much of the country is at a high to very high level for flu activity, with West Virginia (moderate), Vermont (low) and Nevada (insufficient data) as the lone outliers.

The CDC reports at least 11 million illnesses and 5,000 deaths due to the flu so far this season. Flu-like illness accounts for 8% of visits to health care providers, marking the highest activity level since the late 1990s.

Door County Public Health Officer Katie Van Lanen says this flu season is affecting everyone and that symptoms are largely the same.

Van Lanen says if you are worried about the flu, it is never too late to get vaccinated. More than 130.7 million doses of the flu vaccine have been administered, according to the CDC, which is about 13 million fewer doses compared with the same point in the season last year.
