• If you have severe or worsening symptoms, such as difficulty breathing, go immediately to a hospital emergency room. If you do not have severe illness, there is no need to go to a hospital, and nothing will be gained from it.
• If you are at risk of complications, call your doctor to discuss treatment with antiviral medicine.
• Rest, drink plenty of fluids and take the medications you would normally take to treat your symptoms. People under 18 years old should not take aspirin or products containing aspirin, since aspirin can cause a rare but serious illness called Reyes Syndrome in young people with flu.
• Avoid spreading the flu to others by covering your nose and mouth with a tissue when you cough or sneeze, and washing your hands frequently.

• Stay at home until your symptoms resolve. Do not return to work or school until you have been well for 24 hours without the use of fever reducing medication.

• Wash your hands often with soap and warm water. If your hands are not visibly soiled, you can use an alcohol based hand cleaner. Don't touch phones, doorknobs or other shared items before washing your hands. Use your own towel or disposable towels to dry your hands.
• Stay in a separate room and limit your contact with others in your home. Consider wearing a surgical mask when other people are nearby. A surgical mask can prevent germs from spreading.

What should I do if someone in my home has the flu?

• Make sure the person has plenty of tissues and a wastebasket for disposal.
• Make sure soap and warm water are available for hand-washing.
• Encourage the person to remain in his/her room while sick. The person should avoid touching others until 24 hours after the symptoms resolve without the use of fever reducing medications.
• If possible, choose one person to be the primary caregiver and have that person bring meals and other necessities into the person's room. Encourage the person to wear a surgical mask when around others.
• Wear a mask yourself when you are within 3 feet of the person, for example when helping adjust the person's position in bed or helping with feeding or personal hygiene. Masks can be washed with normal laundry detergent and tumble-dried in a hot dryer.
• If you handle the sick person's laundry, wash it with household laundry detergent and tumble dry it on a hot setting. Avoid holding dirty laundry near your face, and clean your hands after handling it. It is not necessary to separate a sick person's laundry from other household laundry.
