Also known as: RSV, Palivizumab, Respiratory syncytial virus immune globulin or Bronchiolitis - RSV
- A person with RSV sneezes, coughs, or blows their nose near you.
- You touch, kiss, or shake hands with someone who is infected by the virus.
- You touch your nose, eyes, or mouth after you have touched something contaminated by the virus, such as a toy or doorknob.
- Attending day care
- Being near tobacco smoke
- Having school-aged brothers or sisters
- Living in crowded conditions
- They usually appear 4 to 6 days after coming in contact with the virus.
- Older children most often have only mild, cold-like symptoms, such as croupy cough (often described as a "seal bark" cough), stuffy nose, or low-grade fever.
- Moist (humidified) air
- Suctioning of nasal secretions
- Fluids through a vein (by IV)
- Premature infants
- Infants with chronic lung disease
- Infants whose immune system does not work well
- Infants with certain forms of heart disease
- Insist that others wash their hands with warm water and soap before touching your baby.
- Have others avoid contact with the baby if they have a cold or fever. If necessary, have them wear a mask.
- Be aware that kissing the baby can spread RSV infection.
- Try to keep young children away from your baby. RSV is very common among young children and easily spreads from child to child.
- Do not smoke inside your house, car, or anywhere near your baby. Exposure to tobacco smoke increases the risk of RSV illness.
Respiratory syncytial virus (RSV) is a very common virus that leads to mild, cold-like symptoms in adults and older healthy children. It can be more serious in young babies, especially those in certain high-risk groups.
RSV is the most common germ that causes lung and airway infections in infants and young children. Most infants have had this infection by age 2. Outbreaks of RSV infections most often begin in the fall and run into the spring.
The infection can occur in people of all ages. The virus spreads through tiny droplets that go into the air when a sick person blows their nose, coughs, or sneezes.
You can catch RSV if:
RSV often spreads quickly in crowded households and day care centers. The virus can live for a half an hour or more on hands. The virus can also live for up to 5 hours on countertops and for several hours on used tissues.
The following increase the risk for RSV:
Symptoms can vary and differ with age:
Infants under age 1 may have more severe symptoms and often have the most trouble breathing:
Exams and Tests
Many hospitals and clinics can rapidly test for RSV using a sample of fluid taken from the nose with a cotton swab.
Antibiotics do not treat RSV.
Mild infections go away without treatment.
Infants and children with a severe RSV infection may be admitted to the hospital. Treatment will include:
A breathing machine (ventilator) may be needed.
More severe RSV disease may occur in the following infants:
Rarely, RSV infection can cause death in infants. However, this is unlikely if the child is seen by a health care provider in the early stages of the disease.
Children who have had RSV bronchiolitis may be more likely to develop asthma.
In young children, RSV can cause:
When to Contact a Medical Professional
Call your provider if breathing difficulties or other symptoms of this disorder appear. Any breathing problems in an infant are an emergency. Seek medical help right away.
To help prevent RSV infection, wash your hands often, especially before touching your baby. Make certain that other people, especially caregivers, take steps to avoid giving RSV to your baby.
The following simple steps can help protect your baby from getting sick:
Parents of high-risk young infants should avoid crowds during outbreaks of RSV. Moderate-to-large outbreaks are often reported by local news sources to provide parents with an opportunity to avoid exposure.
The drug Synagis (palivizumab) is approved for the prevention of RSV disease in children younger than 24 months who are at high risk for serious RSV disease. Ask your doctor if your child should receive this medicine.
