Viruses that can lead to pneumonia include:
- Influenza (flu) A and B viruses are the most common causes in adults.
- Respiratory syncytial virus, or RSV, is more common in infants and children than in adults.
- Others include coronaviruses, rhinoviruses, parainfluenza viruses, and adenoviruses, which can also cause pinkeye.
How Viral Pneumonia Spreads
Viruses that cause pneumonia travel through the air in droplets of fluid after someone sneezes or coughs. These fluids can get into your body through your nose or mouth. You can also get viral pneumonia after touching a virus-laden doorknob or keyboard, then touching your mouth or nose.
Diagnosing Viral Pneumonia
Your doctor’s diagnosis will depend on how severe your infection is. If you have mild symptoms, your doctor may suggest blood tests or a chest X-ray.
If your symptoms are serious, and you are 65 or older (or an infant or young child), the doctor might recommend collecting fluids. She or he may also put a camera down your throat to check your airways.
If a virus is causing your pneumonia, antibiotics won’t help, but your doctor may prescribe an antiviral medication.
- If you have an influenza virus, your doctor may prescribe medications such as oseltamivir (Tamiflu), zanamivir (Relenza), or peramivir (Rapivab). These drugs keep flu viruses from spreading in your body.
- If RSV is the cause of your pneumonia, your doctor may prescribe a medication such as ribavirin (Virazol). This helps to limit the spread of viruses.
When you have pneumonia, it’s important to get plenty of rest. Check back in with your doctor after treatment to make sure your lungs are clear.
The same steps you would take to try to prevent the flu also help lower your chance of pneumonia.
- Wash your hands often. Scrub them with soap and water for at least 20 seconds before you eat or prepare food. When you are in public places, use sanitizer.
- Get a flu vaccination each year at the beginning of flu season.
- Stay away from people who are coughing or sneezing.
- Keep your hands away from your eyes, ears, nose, and mouth.
