More than 90 percent of confirmed cases in Michigan are influenza A (H1N1), which was responsible for a 2009 pandemic.
Angela Minicuci, spokeswoman for the Michigan Department of Community Health, said the total number of flu cases is not unusual because the flu tends to peak in January or February, but the number of H1N1 cases is a concern.
The Michigan Department of Community Health reported an increase in patients of all ages being admitted to hospitals for serious flu cases. Large portions of the hospitalizations have been in young and middle-age adults.
“It’s seriously impacting people we would otherwise think of as healthy,” Minicuci said.
The Centers for Disease Control and Prevention reported that 20 states have a high level of flu activity, eight have moderate activity, six have low activity, and 16 have minimal activity.
As of Dec. 28, laboratories confirmed 142 flu cases and six flu-related deaths in Michigan. In Ottawa County, there have been eight confirmed flu cases between October and December, with a total of 8,190 flu-like cases.
North Ottawa Community Health System spokeswoman Jennifer VanSkiver said the local urgent care center had few confirmed flu cases, but health care workers have seen many residents come in with flu-like symptoms.
Flu symptoms include fever, sore throat, cough, muscle or body aches, headache and fatigue. Residents who have the seasonal flu can infect others from one day before getting sick to five to seven days after.
