It is transmitted very much like a cold. In addition, the flu can be spread by direct hand contact. Although the flu is usually considered to be a respiratory infection, it can affect the entire body. Symptoms of the flu include fever and chills, fatigue, aching of the head and muscles, loss of appetite, and possibly, nausea, vomiting, and sore throat. Receiving the influenza vaccine shots every year can reduce the risk and severity of the flu.
Flu shots are usually available in the fall of each year.
They are encouraged to get a flu shot every year. Colds and flu are more common during the fall and winter months. In the past, some people believed that cold weather, going outdoors with wet hair, or not being dressed warmly caused these respiratory illnesses. We now know that these illnesses are more likely to occur during these seasons because more people are indoors. If you experience frequent respiratory infections, or believe you are in a high-risk group and might need a flu shot, contact your healthcare provider to arrange for an influenza vaccine.
