Bronchiolitis
Bronchiolitis


Respiratory syncytial virus (RSV)

Definition:

Respiratory syncytial virus (RSV) is a very common virus. This virus causes mild, cold-like symptoms in adults and older healthy children. It can cause serious lung infections in young babies, especially those in certain high-risk groups.



Alternative Names: RSV

Causes, incidence, and risk factors:

RSV is the most common respiratory germ in infants and young children. It has infected nearly all infants by the age of two years. Seasonal outbreaks typically begin in the fall and run into the spring.

RSV is spread easily by physical contact. Touching, kissing, and shaking hands with an infected person can spread RSV. You can spread the infection to others if you come in contact with contaminated secretions, which may involve tiny droplets, or objects that droplets have touched. RSV can live for half an hour or more on hands. The virus can also live up to five hours on countertops and for several hours on used tissues. RSV often spreads very rapidly in crowded households and day care centers.

In infants and young children, RSV can cause pneumonia , bronchiolitis (inflammation of the small airways of the lungs), and croup . In healthy adults and older children, RSV is usually a mild respiratory illness. The infection can occur in people of all ages.

Each year up to 125,000 infants are hospitalized due to severe RSV disease, and about 1-2% of these infants die. Infants born prematurely, those with chronic lung disease, those who are immunocompromised, and those with certain forms of heart disease are at increased risk for severe RSV disease. Those who are exposed to tobacco smoke, who attend daycare, who live in crowded conditions, or who have school-age siblings are also at higher risk.



Symptoms:

Note: Symptoms vary and differ with age. Infants under age 1 are most severely affected and often have the most trouble breathing. Older children usually have only mild, cold-like symptoms. Symptoms usually appear 4-6 days after coming in contact with the virus.



Signs and tests:

Rapid tests for this virus can be done at many hospitals and clinics on a fluid sample taken from the nose.



Treatment:

Antibiotics do not help in the treatment of RSV. Mild infections go away without treatment. Infants and children with a severe RSV infection may be admitted to the hospital so they can receive oxygen, humidified air, and fluids by IV.

A breathing machine (ventilator) may be needed.



Support Groups:



Expectations (prognosis):

RSV infection may rarely cause death in infants, but this is unlikely if the child is seen early in the course of the illness.

In older children and adults, the disease will usually be quite mild.

Some evidence suggests that children who have had RSV bronchiolitis have an increased risk for asthma.



Complications:

Calling your health care provider:

Call your health care provider if breathing difficulties or other symptoms of this disorder appear. Any breathing difficulties in an infant should be regarded as an emergency and the appropriate help sought.



Prevention:

A simple way to help prevent RSV infection is to wash your hands often, especially before touching your baby. It's important to make certain that other people, especially care givers, take precautions to avoid giving RSV to your baby. The following simple steps can help protect your baby:

  • 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, it may be helpful to 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.

Parents with high-risk young infants should avoid crowds during outbreaks of RSV. Moderate-to-large outbreaks are often reported in the local news and newspapers to provide parents with an opportunity to avoid exposure.

The drug Synagis (palivizumab) is approved for prevention of RSV disease in children younger than 24 months of age who are at high risk for serious RSV disease. Ask your doctor if your child is at high risk for RSV and whether this medicine should be given.
