What is RSV?
According to Nationwide Children’s Hospital, RSV stands for Respiratory Syncytial Virus. It is a common respiratory virus that can infect the nose, throat, and lungs, typically causing mild, cold-like symptoms.
RSV and other viruses can inflame the small airways (bronchioles) in a child’s lungs causing bronchiolitis. Since bronchiolitis causes the small airways to narrow and fill with mucus, it can make breathing more difficult.
RSV Symptoms
RSV may resemble a cold when it first starts. However, if it progresses medical attention may be needed. According to the CDC, early symptoms of RSV may include:
- Runny or stuffy nose
- Mild cough
- Possible fever (though not always, especially in very young infants)
- Less interest in eating or drinking; decreased appetite or feedings in babies
- Irritability or low energy, especially in infants under 6 months old
More Severe / Progressing Symptoms (bronchiolitis)
- Cough may worsen and last for several weeks (often 3–4 weeks)
- Wheezing or tight breathing (whistling or squeaky sounds)
- Fast and shallow breathing, or increased effort to breathe
- Retractions — skin pulling in between ribs or at the neck when breathing in
- Pauses in breathing (apnea) in infants, sometimes lasting 15–20 seconds or more
- Change in skin color — pale, or bluish tint to lips, fingers, toes, especially during breathing difficulties
- Trouble feeding or drinking, less wet diapers (in babies) signs of dehydration or inability to feed properly
- Being unusually tired, weak, or less playful than normal
When to seek help
Contact your child’s health care provider if:
- Symptoms worsen (e.g., cough or breathing problems worsen)
- Your child is not eating or drinking well, or is producing fewer wet diapers than usual (possible dehydration)
- They become unusually irritable, very sleepy, or find it hard to wake up for feeding (infants)
Seek immediate medical care (call 911 or go to the emergency department) if your child has:
- Trouble breathing rapid or very shallow breathing, working hard to breathe, retractions (skin pulling in when breathing), flaring nostrils.
- Blue or gray color around lips, tongue, face, fingers — sign of low oxygen.
- Pauses in breathing (apnea), especially in very young infants.
- Severe dehydration: refusing to drink, very few or no wet diapers, or signs of dehydration.
According to Cincinnati Children’s Hospital, doctors may diagnose RSV by testing your child’s nasal drainage, X-Ray, or by measuring the amount of oxygen in their blood. Since RSV is a virus, antibiotics are not useful.
Prevention
According to Mayo Clinic Cincinnati Children’s Hospital, the following prevention strategies can help slow the spread of RSV:
- Practice frequent handwashing (wash your hands and your child’s hands after play, diaper changes, before feeding).
- Keep children away from people who are sick. Avoid crowded places during RSV/virus season if possible.
- Encourage covering coughs and sneezes (tissues or elbow) and avoid sharing cups/utensils/toys with children who are ill.
- Ask your child’s doctor about preventive options: in some cases, infants may be eligible for an antibody shot which helps protect against severe RSV.
- Keep up to date on recommended vaccinations as other viruses can also cause bronchiolitis.
