These illnesses can look similar at first, but knowing the differences can help you decide how to care for your child and when it’s time to head to the Emergency Room. Here’s a parent-friendly breakdown of cold, flu, and RSV symptoms along with what to watch for. 

The Common Cold 

Common colds are usually mild and come on gradually. Symptoms include: 

• Runny or stuffy nose 

• Sneezing 

• Sore throat 

• Mild cough 

• Low-grade fever (if any) 

Most colds improve on their own in 7 to 10 days and can be managed with rest, fluids, and over-the-counter remedies. However, sometimes cough and congestion can last longer than 10 days. 

Influenza (Flu) 

Flu symptoms come on suddenly and tend to be more intense. Look for: 

• High fever and chills 

• Body aches 

• Fatigue or weakness 

• Headache 

• Dry cough or sore throat 

• Vomiting or diarrhea (more common in children) 

The flu can lead to complications like pneumonia, especially in young children. If your child is struggling to breathe or has a persistent high fever, seek medical care. 

RSV (Respiratory Syncytial Virus) 

RSV is a common virus that can be dangerous for infants and toddlers. Symptoms may include:

• Severe congestion or a runny nose 

• Frequent coughing or wheezing 

• Difficulty feeding (in babies) 

• Rapid breathing or chest retractions 

• Fatigue or irritability 

If your child is under two and shows signs of labored breathing, dehydration, or lethargy, visit the ER immediately. 

When to Go to the ER 

Seek emergency care if your child has: 

• Trouble breathing or wheezing 

• Blue lips or face 

• High fever that won’t go down 

• Dehydration (dry mouth, no tears, few wet diapers) 

• Unresponsiveness or extreme fatigue 

• Seizures or confusion
