The most important thing to know about the flu this year is that it can be very serious. It can cause fever, body aches, fatigue and sometimes vomiting and diarrhea. People who are at higher risk for complications from the flu should get a flu shot as soon as possible. You should also take extra precautions to avoid getting sick by washing your hands frequently and avoiding close contact with people who may be sick.
