How do I know if I have the flu? You may have the flu if you have some or all of these symptoms: fever*, cough, sore throat, runny or stuffy nose, body aches, headache, chills, fatigue. Sometimes, diarrhea and vomiting are symptoms of the flu.
*It's important to note that not everyone with flu will have a fever.
What should I do if I get sick? Most people with the flu have mild illness and do not need medical care or antiviral drugs. If you get sick with flu symptoms, in most cases, you should stay home and avoid contact with others except to get medical care.
If, however, you have symptoms of flu and are in a high risk group, or are very sick or worried about your illness, contact your health care provider (doctor, physician assistant, etc.).
Do I need to go the emergency room if I am only a little sick? No. The emergency room should be used for people who are very sick. You should not go to the emergency room if you are only mildly ill.
If you have the emergency warning signs of flu sickness, you should go to the emergency room. If you get sick with flu symptoms and are at high risk of flu complications or you are concerned about your illness, call your health care provider for advice. If you go to the emergency room and you are not sick with the flu, you may catch it from people who do have it.
