Respiratory syncytial virus (RSV) infection

Respiratory syncytial virus can cause bronchiolite in infants and severe infections at other ages.

Documentary Enrichment: · General information

Essentials

Frequent respiratory infection may be severe in infants, elderly or fragile people.

Agent
Respiratory syncytial virus
Transmission or exposure
Respiratory tract · Close contact

Situation and vulnerability

In particular, infants, the elderly and people with certain heart, lung or immunosuppression diseases are affected.

Signs and limits of their interpretation

Cold, cough and fever are possible. Difficult breathing, respiratory pauses or feeding difficulties in an infant require rapid help.

Diagnosis and monitoring

Clinical assessment is about breathing and hydration. A sample can identify the virus when it is useful, without replacing the child's surveillance.

Prevention and care

Reduce symptomatic contact and practice hand hygiene. The means of immunization, whether vaccine or antibody, depending on the public, depend on national recommendations.

Practical issues

Is a preventive antibody a vaccine?

No. It brings antibodies directly; a vaccine stimulates an immune response. Their particulars and modalities are not interchangeable.

Preparing for an exchange with a professional

  • Age and possible prematurity
  • Breathing, eating and wet diapers
  • Immunization received and history

Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.

Individual decisionThe choice of a test, treatment or prevention depends on the local situation and recommendations. In case of distress, call 911.
