What should I do if I get sick?

Most people with 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 higher-risk group, or are very sick or worried about your illness, contact your health care provider (doctor, physician assistant, etc.).

Certain people are at increased risk of serious flu-related complications (including young children, people 65 and older, pregnant people, and people with certain medical conditions). For a full list of people at increased risk of flu-related complications, see People at Higher Risk of Developing Flu–Related Complications. If you are in a higher-risk group and develop flu symptoms, it’s best for you to contact your doctor early in your illness. Remind them about your higher-risk status for flu. CDC recommends that people at higher risk for complications should get antiviral treatment as early as possible, because benefit is greatest if treatment is started within 2 days after illness onset.

Do I need to go to 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 emergency warning signs of flu sickness, you should go to the emergency room. If you get sick with flu symptoms and are at higher risk of flu complications or you are concerned about your illness, call your health care provider for advice.

People experiencing any of these warning signs should obtain medical care right away.

Are there medicines to treat flu?

Yes. There are drugs your doctor may prescribe for treating flu called “antivirals.” These drugs can make you better faster and may also prevent serious complications. See Treatment – Antiviral Drugs for more information.

How long should I stay home if I’m sick?

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 need to use a fever-reducing medicine, such as Tylenol®. Until then, you should stay home from work, school, travel, shopping, social events, and public gatherings.

CDC also recommends that children and teenagers (anyone aged 18 years and younger) who have flu or are suspected to have flu should not be given Aspirin (acetylsalicylic acid) or any salicylate containing products (e.g. Pepto Bismol); this can cause a rare, very serious complication called Reye’s syndrome. More information about Reye’s syndrome can be found here.

What should I do while I’m sick?

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.
