RSV in Children: Symptoms Parents Should Watch For and When to Seek Care
Respiratory syncytial virus, or RSV, often starts with cold-like symptoms such as a runny nose, congestion, cough and reduced appetite. Most children recover with supportive care, but RSV can cause bronchiolitis or pneumonia—especially in young infants and children with certain medical conditions.
The most important signs for parents to watch are how hard the child is breathing, whether the child is drinking and urinating normally, and whether the child is alert and interacting as usual. Fast or labored breathing, ribs pulling inward, grunting, pauses in breathing, blue or gray lips, poor fluid intake or unusual sleepiness require prompt medical attention. Severe breathing difficulty, a change in skin color, unresponsiveness or pauses in breathing require emergency care.
What Is RSV?
RSV is a common respiratory virus that infects the nose, throat and lungs. Nearly all children are infected with RSV by age 2, and many infections are no worse than a typical cold.
RSV deserves extra attention because it can move into the lower airways and cause:
- Bronchiolitis: inflammation of the small airways in the lungs
- Pneumonia: infection of the lungs
According to the Centers for Disease Control and Prevention, RSV can be dangerous for infants and some young children. Younger age generally means greater risk, although older children can also become seriously ill.
RSV activity in most of the United States usually begins in the fall, peaks during the winter and declines in the spring. The timing and intensity of each season can vary.
What Are the Symptoms of RSV in Children?
RSV symptoms often appear in stages rather than all at once. A child may begin with a runny nose or reduced appetite and develop a cough a day or two later. Symptoms may become more noticeable several days into the illness.
Common RSV symptoms include:
- Runny or stuffy nose
- Cough
- Sneezing
- Fever
- Decreased appetite
- Reduced energy or activity
- Wheezing
According to the American Academy of Pediatrics, RSV symptoms are often most severe around days 3 through 5 and may last approximately 7 to 14 days. The exact pattern varies, so the child’s breathing, hydration and behavior are more important than the day of illness alone.
RSV Symptoms in Babies
Very young infants do not always show the same symptoms as older children. They may have little or no fever. Their signs may include:
- Irritability or unusual fussiness
- Decreased activity
- Poor feeding or taking longer to feed
- Cough or congestion
- Breathing difficulty
- Pauses in breathing lasting more than 10 seconds, known as apnea
How Can You Tell If a Child Is Working Too Hard to Breathe?
A child does not need to know how to describe shortness of breath for a parent to recognize it. Watch the child’s chest and abdomen while they are calm.
Signs of Increased Breathing Effort
- Breathing faster than usual
- Nostrils widening or flaring with each breath
- Grunting during breathing
- Wheezing
- The belly moving strongly with each breath
- Skin pulling inward between or below the ribs
- Tugging at the base of the neck
- Head bobbing with each breath in an infant
- Difficulty feeding because the child has to stop repeatedly to breathe
The pulling-in motion around the ribs or neck is called a retraction. It means the child is using extra muscles to breathe and should be evaluated promptly.
RSV Symptoms: Home Care, Same-Day Care or Emergency Care?
Age, medical history, symptom severity and how quickly the condition is changing all affect the safest level of care.
Monitor Closely
- Mild congestion or cough
- Breathing comfortably
- Drinking reasonably well
- Alert and responsive
Seek Same-Day Advice
- Worsening cough or wheezing
- Faster breathing or mild retractions
- Poor feeding
- Fewer wet diapers
Call 911 or Use the ER
- Severe breathing difficulty
- Pauses in breathing
- Blue or gray lips or skin
- Unresponsiveness
| Level of Care | Signs You May Notice | What to Do |
|---|---|---|
| Monitor closely at home | Mild congestion or cough; breathing comfortably; drinking reasonably well; normal skin color; alert and responsive | Offer fluids, clear nasal mucus gently, monitor breathing and follow age-appropriate fever guidance |
| Contact a healthcare professional or seek same-day care | Worsening cough; wheezing; faster breathing; mild retractions; poor feeding; fewer wet diapers; symptoms worsening instead of improving; parent is concerned | Call the child’s pediatrician or an appropriate pediatric urgent care clinic for guidance and evaluation |
| Emergency department or 911 | Severe breathing difficulty; gasping; pronounced retractions; grunting with distress; pauses in breathing; blue, gray or very pale lips or skin; unresponsiveness; child cannot drink because of breathing difficulty | Call 911 or go to the nearest emergency department immediately |
When Should You Call the Pediatrician or Visit Urgent Care for RSV?
Contact the child’s pediatrician or seek same-day medical care when symptoms are not an obvious emergency but the child needs evaluation. Examples include:
- Breathing faster or harder than usual
- New wheezing or persistent noisy breathing
- Mild pulling inward around the ribs or neck
- Reduced feeding or difficulty finishing feeds
- Fewer wet diapers or other possible dehydration signs
- Repeated vomiting or difficulty keeping fluids down
- Fever in a child whose age or medical history makes fever more concerning
- Symptoms that are getting worse after several days
- Symptoms that have not started improving after about a week
- Ear pain, ear drainage or another possible secondary infection
- A child with a high-risk medical condition who develops respiratory symptoms
- Any time a parent feels that the child is significantly less active, less alert or not acting normally
Urgent care may be appropriate for a stable child who needs a same-day examination, oxygen-level check or respiratory testing but does not have severe breathing difficulty or another emergency warning sign. Call ahead if you are unsure whether the child’s age or symptoms are appropriate for a specific urgent care location.
When Is RSV an Emergency?
Call 911 or go to the nearest emergency department if a child has:
- Severe difficulty breathing, gasping or struggling for each breath
- Deep or rapidly worsening pulling inward around the ribs, abdomen or neck
- Pauses in breathing
- Blue, gray or very pale lips, face or skin, depending on skin tone
- Extreme sleepiness, limpness, confusion or difficulty waking
- Inability to drink because breathing is too difficult
- Signs of severe dehydration, especially with marked sleepiness or weakness
- A rapidly worsening condition that feels immediately dangerous
Do not drive yourself if the child may stop breathing, is unresponsive or could deteriorate during transport. Call 911 so emergency medical personnel can begin care on the way to the hospital.
Which Children Are at Higher Risk for Severe RSV?
Any child can develop a serious RSV infection, but the risk is higher for:
- Young infants, particularly those 6 months old or younger
- Babies born prematurely
- Children with chronic lung disease
- Children with congenital heart disease
- Children with weakened immune systems
- Children with severe cystic fibrosis
- Children with neuromuscular conditions that make swallowing or clearing mucus difficult
- Some American Indian and Alaska Native children
Parents of a high-risk child should ask the child’s specialist or pediatrician for an individualized plan before respiratory virus season. A clinician may recommend earlier evaluation even when symptoms initially appear mild.
How Is RSV Diagnosed?
RSV, flu, COVID-19 and the common cold can cause many of the same symptoms. A healthcare professional may diagnose a respiratory infection based on the child’s history, physical examination, breathing effort and oxygen level.
A nasal swab may be used when identifying the virus would affect care, infection precautions or decisions for a high-risk child. Testing is not always necessary for a mild illness, and a positive RSV result does not determine severity by itself.
Depending on the symptoms, a clinician may also evaluate for an ear infection, pneumonia, asthma flare or dehydration. Chest X-rays are not routinely needed for every child with suspected RSV but may be considered when the examination suggests another problem.
California Urgent Care Center promotes rapid testing for RSV, flu and COVID-19. Test availability and the ages evaluated may differ by location, so call the preferred clinic before visiting when a specific test is important.
How Is RSV Treated?
There is no routine antiviral treatment for RSV. Antibiotics do not treat RSV because RSV is caused by a virus, not bacteria. They may be prescribed only when a clinician identifies a separate bacterial infection.
For mild RSV, care focuses on comfort, breathing and hydration:
- Offer breast milk, formula or other age-appropriate fluids frequently.
- Give smaller, more frequent feeds if congestion makes feeding difficult.
- Use saline nose drops and gentle suction, especially before feeding or sleep.
- Use a clean cool-mist humidifier if it helps the child breathe more comfortably.
- Keep the child away from tobacco smoke, vaping aerosol and other airway irritants.
- Ask a healthcare professional about the correct fever or pain medicine and dose for the child’s age and weight.
Seek medical advice if the child cannot maintain hydration, is breathing harder or is becoming less alert. Children hospitalized with severe RSV may need oxygen, intravenous fluids or breathing support. These treatments require hospital-level monitoring and are not provided in a routine urgent care setting.
How Long Does RSV Last, and How Long Is It Contagious?
Most RSV infections improve within one to two weeks, although a cough can linger. Symptoms may be at their worst during days 3 through 5, so a child who seemed mildly ill at first should still be watched closely.
The CDC states that people with RSV are usually contagious for 3 to 8 days and may spread the virus a day or two before symptoms begin. Some infants and people with weakened immune systems can remain contagious longer.
Follow the child’s school or childcare illness policy. In general, keep a sick child home while the child has a fever, cannot comfortably participate in normal activities or needs more care than the setting can safely provide.
How Can Families Reduce the Spread of RSV?
RSV spreads through coughs and sneezes, direct contact and contaminated surfaces. Families can reduce exposure by:
- Washing hands frequently with soap and water
- Covering coughs and sneezes
- Cleaning frequently touched surfaces and shared toys
- Avoiding close contact with babies when sick
- Not kissing a baby’s face when you have cold symptoms
- Keeping sick children home from school or childcare
- Improving indoor air by bringing in outdoor air or using appropriate filtration
- Avoiding exposure to tobacco smoke and vaping aerosol
RSV infection does not create permanent immunity. Children and adults can get RSV more than once, even during the same season.
Can RSV Be Prevented in Babies?
There are two main ways to protect infants from severe RSV disease:
- Maternal RSV vaccination during pregnancy, which passes protective antibodies to the baby.
- A long-acting preventive antibody given to the infant, such as nirsevimab or clesrovimab.
Most babies do not need both approaches. Current guidance generally recommends infant RSV antibody protection for babies younger than 8 months who are born during or entering their first RSV season when they are not adequately protected through maternal vaccination. Some children ages 8 through 19 months with a higher risk of severe disease may also qualify before their second RSV season.
These preventive antibodies are not treatment for a child who is already sick, and they are not traditional vaccines. Eligibility, timing, product availability and guidance can change. Parents and expectant parents should discuss the current recommendation with an obstetric clinician or the child’s pediatrician.

Frequently Asked Questions
What are the first signs of RSV in a child?
RSV often begins with a runny or stuffy nose, reduced appetite, cough, sneezing or fever. In a very young infant, the first signs may instead be fussiness, decreased activity, poor feeding or changes in breathing.
How do I know if my child’s RSV is an emergency?
Call 911 or seek emergency care for severe breathing difficulty, gasping, deep pulling inward around the ribs or neck, pauses in breathing, blue or gray lips or skin, unresponsiveness or inability to drink because breathing is too difficult.
Can urgent care test a child for RSV?
Many urgent care centers can perform a nasal swab for RSV, often as part of respiratory testing that may also include flu or COVID-19. Testing is not necessary for every mild illness. Call the clinic to confirm current test availability and whether the child’s age and symptoms are appropriate for urgent care.
How long does RSV usually last in children?
RSV symptoms commonly last about one to two weeks and may be most intense around days 3 through 5. A cough may continue after other symptoms improve. Seek medical advice if symptoms are worsening, breathing becomes difficult or the child is not drinking enough.
Should a baby younger than 3 months be evaluated for RSV symptoms?
Parents should contact the baby’s healthcare professional promptly for respiratory symptoms, poor feeding or behavior changes. A rectal temperature of 100.4°F (38°C) or higher in a baby younger than 3 months requires an immediate call to a healthcare professional.
Do antibiotics treat RSV?
No. Antibiotics do not treat RSV because it is a viral infection. A clinician may prescribe an antibiotic only if the child also develops a bacterial infection, such as certain ear infections or bacterial pneumonia.
