is a lung infection caused by a virus, such as influenza. You can get a viral infection by breathing in the virus or by touching something that has the virus on it. Viral pneumonia can develop if a virus in your body travels to your lungs.

Most people with viral pneumonia are treated at home. Older adults and people with health problems may need to stay in the hospital. You may need any of the following:
- Antiviral medicine is given to treat an infection caused by a virus. Antivirals work best if taken within 72 hours of infection. After 72 hours, the medicine can still help shorten the amount of time you have the virus, or reduce your symptoms.
- 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. Do not use more than 4 grams (4,000 milligrams) total of acetaminophen in one day.
- 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.
- Airway clearance techniques are exercises to help remove mucus so you can breathe more easily. Your healthcare provider will show you how to do the exercises. These exercises may be used along with machines or devices to help decrease your symptoms.
- Respiratory support is given to help you breathe. You may receive oxygen to increase the level of oxygen in your blood. You may also need a machine to help you breathe.
Manage your symptoms:
- Rest as needed. Rest often while you recover. Slowly start to do more each day.
- Drink liquids as directed. Ask how much liquid to drink each day and which liquids are best for you. Liquids help thin your mucus, which may make it easier for you to cough it up.
- Do not smoke. Avoid secondhand smoke. Smoking makes it harder for you to get better. Nicotine and other chemicals in cigarettes and cigars can cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Use a cool mist humidifier. A humidifier will help increase air moisture in your home. This may make it easier for you to breathe and help decrease your cough.
- Keep your head elevated. You may be able to breathe better if you lie down with the head of your bed up.
Prevent viral pneumonia:
- Prevent the spread of germs. Wash your hands often with soap and water. Use gel hand cleanser when there is no soap and water available. Do not touch your eyes, nose, or mouth unless you have washed your hands first. Cover your mouth when you cough. Cough into a tissue or your shirtsleeve so you do not spread germs from your hands. If you are sick, stay away from others as much as possible.
- Ask about vaccines. You may need a vaccine to help prevent pneumonia. Get an influenza (flu) vaccine every year as soon as it becomes available.
Follow up with your healthcare provider as directed:
