Influenza (the flu) is an infection caused by the influenza virus. The virus spreads through direct contact with someone who has the flu. For example, a person with the virus on his or her hands can spread it by shaking hands with someone. You may be able to spread the flu to others for 1 week or longer after signs or symptoms appear.

DISCHARGE INSTRUCTIONS:

Call your local emergency number (911 in the US) if:

• You have trouble breathing, and your lips look purple or blue.
• You have a seizure.

Seek care immediately if:

• You are dizzy, or you are urinating less or not at all.
• You have a headache with a stiff neck, and you feel tired or confused.
• You have new pain or pressure in your chest.
• Your symptoms, such as shortness of breath, vomiting, or diarrhea, get worse.
• Your symptoms, such as fever and coughing, seem to get better, but then get worse.

Call your doctor if:

• You have new muscle pain or weakness.
• You have questions or concerns about your condition or care.

Medicines:

You may need any of the following:

• Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly.
• NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
• Antivirals help fight a viral infection.

Drink liquids as directed

to help prevent dehydration. Ask how much liquid to drink each day and which liquids are best for you.

Prevent the spread of germs:

• Wash your hands often. Wash your hands several times each day. Wash after you use the bathroom, change a child's diaper, and before you prepare or eat food. Use soap and water every time. Rub your soapy hands together, lacing your fingers. Wash the front and back of your hands, and in between your fingers. Use the fingers of one hand to scrub under the fingernails of the other hand. Wash for at least 20 seconds. Rinse with warm, running water for several seconds. Then dry your hands with a clean towel or paper towel. Use hand sanitizer that contains alcohol if soap and water are not available. Do not touch your eyes, nose, or mouth without washing your hands first.
• Cover a sneeze or cough. Use a tissue that covers your mouth and nose. Throw the tissue away in a trash can right away. Use the bend of your arm if a tissue is not available. Wash your hands well with soap and water or use a hand sanitizer.
• Stay away from others while you are sick. Avoid crowds as much as possible.
• Ask about vaccines you may need. Talk to your healthcare provider about your vaccine history. Your provider can tell you which vaccines you need, and when to get them.
  • Get the influenza (flu) vaccine as soon as recommended. The vaccine is usually available starting in September or October. Flu viruses change, so it is important to get a flu vaccine every year.
  • Get the pneumonia vaccine if recommended. This vaccine is usually recommended every 5 years. Your provider will tell you when to get this vaccine, if needed.

Follow up with your doctor as directed:

Write down your questions so you remember to ask them during your visits.
