About RSV

Respiratory Syncytial Virus (RSV) is a common respiratory virus that usually causes mild, cold-like symptoms.  However, it can be a serious illness for infants and older adults. In most years, RSV is most common from October through March. Learn more about RSV, how RSV spreads, how to care for someone with symptoms of RSV, and what you can do to prevent RSV.

Protect Yourself From RSV

Immunization and everyday prevention activities are the best ways to protect yourself and your family from RSV.

Everyday measures can help reduce the spread of RSV and other respiratory illnesses. These include:

  • Stay home when sick.
  • Cover your coughs and sneezes with a tissue or your shirt sleeve, not your hands.
  • Wash your hands often with soap and water for at least 20 seconds.
  • Avoid touching your face with unwashed hands.
  • Avoid close contact with others, such as kissing, shaking hands, and sharing cups and eating utensils.
  • Clean frequently touched surfaces such as doorknobs and mobile devices.

RSV Immunization Recommendations
