Everyone feels the effects of the flu bug now and then, but do you ever wonder how it enters our bodies in the first place? I wanted to provide some information about the flu that you might not have known already, and I learned some new facts myself!
I know you probably think of nausea and vomiting when you think of the flu, but those aren't really considered flu symptoms. Real symptoms include a fever, coughing, sore throat, fatigue, headache, body aches, and chills. Nausea, vomiting, and diarrhea sometimes occur, but those symptoms don't usually mean the flu.
