Respiratory Syncytial Virus (RSV)

Respiratory syncytial virus (RSV) is a contagious virus that affects the lungs and breathing passages. Most children get RSV infection by age 2, but you can get infected at any age and more than once in your life. The symptoms are similar to the common cold. Most people recover in a week or two, but others at high risk may get very sick and develop pneumonia or bronchiolitis. There is no vaccine, but scientists are working to develop one. Until then, there are ways you can help prevent RSV infection.

RSV Can Be Serious

For most people, RSV infections are mild and clear on their own. But some people develop severe infections, such as pneumonia and bronchiolitis. People at high risk include premature babies, young children with chronic lung or heart disease, older adults, and people with weakened immune systems.

Wash Your Hands Often

Wash your hands often with soap and water for 20 seconds, and help young children do the same. Proper hand hygiene can help protect you from getting RSV infection as well as prevent the spread of infection to others when you are sick.

Cover Your Cough and Sneeze

RSV can spread when an infected person coughs or sneezes. To help prevent germs from spreading, cover your coughs and sneezes with a tissue or your upper shirt sleeve, not your bare hands. Throw the tissue in the trash and wash your hands.

Avoid Sharing When Sick

You can get RSV infection if you share cups or eating utensils with others. You can also get infected if you touch surfaces, such as toys or doorknobs, that have the virus on them, then touch your eyes, nose or mouth.

Prevention Tips

• Wash your hands often with soap and water for 20 seconds, and help young children do the same.
• Cover your coughs and sneezes with a tissue or your upper shirt sleeve, not your bare hands. Throw the tissue in the trash.
• Avoid touching your eyes, nose, and mouth with unwashed hands.
• Avoid close contact, such as kissing, or sharing cups or eating utensils, with sick people.
• Clean and disinfect frequently touched surfaces, such as toys and doorknobs.
