Respiratory syncytial virus (RSV) is a common but potentially serious virus that infects the respiratory tract of most children before their second birthday.
While many cases resemble a mild cold, RSV can sometimes pose risks for infants—especially the very young or those with underlying health issues. Understanding RSV symptoms, recognizing warning signs, and knowing when to act is essential for caregivers.
Understanding RSV
RSV is highly contagious and typically spreads through respiratory droplets or by touching contaminated surfaces.
According to the World Health Organization, almost all babies are infected before their second birthday. WHO also estimates that each year, RSV causes approximately 3.6 million hospitalizations and about 100,000 deaths in children under five worldwide.
In healthy infants, RSV may show up as mild cold-like symptoms, but for premature babies or those with conditions like congenital heart disease, RSV can lead to severe lower respiratory tract infections such as bronchiolitis or pneumonia.
Early symptoms to watch for
In its earliest stages, RSV often mimics a typical upper respiratory infection. You might notice:
- Runny or stuffy nose
- Mild cough
- Sneezing
- Decreased appetite
- Irritability
- Low-grade fever
These symptoms can appear four to six days after exposure. Because they're common to many viruses, RSV symptoms may not be recognized immediately.
Progression and concerning developments
For most babies, symptoms resolve within one to two weeks, according to the Centers for Disease Control and Prevention (CDC). However, if RSV progresses—or symptoms intensify—watch for:
- Worsening cough that becomes persistent or productive
- Rapid or labored breathing, indicated by chest retractions (skin pulling in under the ribs), flaring nostrils, or pronounced tummy movements
- Wheezing, a high-pitched sound when breathing out
- Bluish lips, tongue, or face (cyanosis), signaling low oxygen levels
- Excessive sleepiness or difficulty waking up
- Poor feeding or decreased wet diapers, which may signal dehydration
If you notice these signs, it’s critical to seek medical attention promptly.
When to call the doctor or go to the ER
Contact your pediatrician if your baby exhibits:
- Breathing difficulties (e.g., fast breathing, grunting, or retractions)
- Poor intake of fluids (e.g., fewer than half the usual amount of breast milk/formula)
- Signs of dehydration (e.g., fewer than six wet diapers per day, dry mouth, or sunken fontanelle (the soft spot on the head))
- High or persistent fever, especially in infants under three months
- Decreasing responsiveness, irritability, or inconsolable crying
- Any blueness around the face or lips
For newborns or high-risk infants (like those born prematurely), even mild symptoms warrant a doctor’s evaluation.
What you can do at home
If your baby's symptoms are mild, supportive care at home can help them stay comfortable and recover more quickly. Here are some practical steps you can take:
- Keep baby hydrated: Offer breast milk or formula frequently, even in small amounts.
- Use a humidifier: Cool-mist humidifiers can help ease breathing.
- Nasal suction: Gentle use of a bulb syringe or saline drops can clear nasal passages.
- Keep the baby upright: Mild elevation may ease congestion.
- Watch temperature: Treat fever as advised by your pediatrician, but be cautious with over-the-counter medications and always follow dosage instructions for infants.
Prevention is key
Since RSV spreads easily, prevention efforts can significantly reduce your baby’s risk. Keeping your home environment clean and avoiding unnecessary exposure during peak RSV season are important strategies. Consider the following protective measures:
- Wash your hands before handling your baby.
- Avoid crowds and sick people, especially during RSV season (typically fall through early spring).
- Clean surfaces and toys frequently.
- Breastfeed when possible to offer protective antibodies.
RSV and the per diem nursing world
For per diem nurses, especially those working in pediatric or neonatal care, staying vigilant about RSV symptoms is essential—not only for the health of your patients but also for your own professional preparedness.
Recognizing early warning signs, managing care plans, and supporting families during RSV season are key responsibilities that make pediatric nurses vital to improving outcomes for young patients.

Important summary points
To wrap up, here are some crucial takeaways every caregiver and nurse should remember when it comes to RSV and infants:
- RSV is common in infants and ranges from mild to severe.
- Early symptoms mimic a cold; take note if a cough worsens or breathing becomes labored.
- Seek medical care quickly if your baby shows signs of distress or dehydration.
- Prevention through hygiene, breastfeeding, and cautious exposure can reduce risk.
RSV is common in babies but should be taken seriously
RSV is a common but potentially serious illness in babies, especially those under six months or with underlying conditions.
While many cases are mild and resolve on their own, it’s important for caregivers to recognize the signs that the virus may be progressing—such as labored breathing, dehydration, or extreme fatigue—and to seek medical help when necessary. Prevention through good hygiene, limited exposure during RSV season, and proactive care can go a long way in protecting your little one.
For nurses—especially those working PRN or per diem—being informed and ready to respond to RSV cases is part of delivering excellent care.
