“I want you to watch for fever that’s not going away or caused by no known reason. Getting fever chills, nausea, vomiting, body aches all over, nasal drainage and congestion. Ear pain and just feeling a sense of blah. It’s a good sign that you may have more than just a cold, that you have the flu. At one point, Michigan was the second-largest outbreak in the country for the flu and Influenza B is the prominent strain this year,” said Norwood.

Physicians say the flu shot is the number one recommendation to prevent the spread of the virus.

Keeping your hands clean can also reduce the chance of infection.
