You may have the flu if you have some or all of these symptoms:
*It's important to note that not everyone with flu will have a fever.
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 other people except to get medical care.
If, however, you have symptoms of flu and are in a high risk group, are very sick or worried about your illness, contact your health care provider (doctor, physician’s assistant, etc.).
Certain people are at greater risk of serious flu-related complications (including young children, elderly persons, pregnant women and people with certain long-term medical conditions) and this is true both for seasonal flu and novel flu virus infections. (For a full list of people at higher risk of flu-related complications, see People at High Risk of Developing Flu–Related Complications). If you are in a high risk group and develop flu symptoms, it’s best for you to contact your doctor. Remind them about your high risk status for flu.
Health care providers will determine whether influenza testing and possible treatment are needed. Your doctor may prescribe antiviral drugs that can treat the flu. These drugs work better for treatment the sooner they are started.
In addition to the signs above, get medical help right away for any infant who has any of these signs:
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.
Yes. There are drugs your doctor may prescribe for treating the flu called “antivirals.” These drugs can make you better faster and may also prevent serious complications. See Treatment - Antiviral Drugs for more information.
CDC recommends that you stay home for at least 24 hours after your fever is gone except to get medical care or other necessities. Your fever should be gone without the use of a fever-reducing medicine, such as Tylenol®. You should stay home from work, school, travel, shopping, social events, and public gatherings.
Stay away from others as much as possible to keep from infecting them. If you must leave home, for example to get medical care, wear a facemask if you have one, or cover coughs and sneezes with a tissue. Wash your hands often to keep from spreading flu to others.
