LA CROSSE, WI (Ben Caxton) — Mayo Clinic Health System has seen a major uptick in one area involving the flu. Lab numbers indicate Influenza A more than doubled last week in both patients coming through clinical and emergency room settings as of last week. 33 cases were reported of Influenza A compared to 13 just the week before. Meanwhile, lab numbers show that cases of Influenza B have showed a very slight decrease but has remained steady throughout the month of January. Flu symptoms often come on suddenly and at first may seem like a common cold with a runny nose or congestion, sneezing, and sore throat but can progress to include feeling feverish, body aches and muscle stiffness, chills and sweats, headaches, cough, fatigue and weakness, and nasal congestion. Doctors remind everyone the best ways to prevent either coming in contact with the flu or sharing it with others includes practicing good health habits, implement healthy life strategies like eating and sleeping well, covering your cough or staying home when feeling ill, and getting your flu shot.
