Respiratory Syncytial Virus (RSV) is a common viral infection that primarily affects young children, often causing cold-like symptoms. While most cases are mild, RSV can lead to more severe respiratory issues, especially in infants and children with weakened immune systems. One of the most common concerning symptoms for parents is fever. But how long does an RSV-related fever last in children? In this blog, we’ll take a closer look at this symptom and explain when it’s necessary to seek professional treatment.

Typical Duration of Fever in RSV
A fever is a natural immune response to infection, helping the body fight off viruses. In children with RSV, a fever typically lasts between 2 to 4 days. However, the exact duration can vary based on the child’s immune system, age, and overall health.
- Mild Cases: Fever usually lasts 2-3 days before resolving on its own.
- Moderate to Severe Cases: Fever may persist for 4 days or longer, especially if the child develops complications like pneumonia or bronchiolitis.
Most children with RSV will experience mild to moderate fever. However, a high fever (above 101°F) should be treated promptly. If the fever lasts more than 5 days, worsens, or is accompanied by severe symptoms, it’s advisable to consult a healthcare provider.
Other Symptoms of RSV in Children
Along with fever, RSV can cause:
- Runny nose and nasal congestion
- Coughing and sneezing
- Wheezing or difficulty breathing
- Decreased appetite
- Fussiness or irritability
- Fatigue
Severe cases may lead to bronchiolitis or pneumonia, which can cause rapid breathing and bluish skin due to low oxygen levels. These signs require urgent medical attention at the ER.
How To Manage an RSV-Related Fever at Home
If your child has RSV with a fever, here’s how you can help:
- Hydration: Offer plenty of fluids and electrolyte solutions to prevent dehydration
- Fever Reducers: Acetaminophen or ibuprofen can help lower fever and relieve discomfort. Always follow dosage instructions and consult a healthcare provider for guidelines.
- Cool Compress: A lukewarm washcloth on the forehead can provide comfort.
- Rest: Ensure your child gets plenty of sleep to aid recovery.
- Humidifier: Using a cool-mist humidifier can ease congestion and improve breathing.
While most RSV cases resolve on their own, you should seek medical care if your child’s fever lasts more than 5 days, the fever is higher than 104°F, you notice signs of dehydration, or any other concerning symptoms. For infants under 3 months old, any fever above 100.4°F should be evaluated by a doctor immediately.
