Respiratory syncytial virus

Respiratory syncytial  virus (RSV), which causes infection of the lungs and breathing passages, is a major cause of respiratory illness in young children.

RSV is highly contagious, and spreads through droplets containing the virus when someone coughs or sneezes. It also can live on surfaces (such as counter tops or doorknobs) and on hands and clothing, so it can easily spread when a person touches something contaminated.

Those at greatest risk for severe illness from RSV include

• Premature infants
• Very young infants, especially those 6 months and younger
• Children younger than 2 years old with chronic lung disease
• Children younger than 2 years old with chronic heart disease
• Children with weakened immune systems
• Children who have neuromuscular disorders, including those who have difficulty swallowing or clearing mucus secretions

 RSV season occurs each year in most regions of the U.S. during fall, winter, and spring. If you have contact with an infant or young child, especially those who were born prematurely, are very young, have chronic lung or heart disease or a weakened immune system, you should take extra care to keep the infant healthy by doing the following:

• Wash your hands often
  Wash your hands often with soap and water for 20 seconds, and help young children do the same. If soap and water are not available, use an alcohol-based hand sanitizer. Washing your hands will help protect you from germs.
• Keep your hands off your face
  Avoid touching your eyes, nose, and mouth with unwashed hands. Germs spread this way.
• Avoid close contact with sick people
  Avoid close contact, such as kissing, and sharing cups or eating utensils with people who have cold-like symptoms.
• Cover your coughs and sneezes
  Cover your mouth and nose with a tissue or your upper shirt sleeve when coughing or sneezing. Throw the tissue in the trash afterward.
• Clean and disinfect surfaces
  Clean and disinfect surfaces and objects that people frequently touch, such as toys and doorknobs. When people infected with RSV touch surfaces and objects, they can leave behind germs. Also, when they cough or sneeze, droplets containing germs can land on surfaces and objects.
• Stay home when you are sick
  If possible, stay home from work, school, and public areas when you are sick. This will help protect others from catching your illness.
