Deciphering Between a Cold and RSV in Infants

As a parent, distinguishing between a common cold and Respiratory Syncytial Virus (RSV) in infants can be challenging, yet it’s crucial for their health and well-being. Both conditions affect the respiratory system, but RSV can be more severe, especially in young infants. This post will guide you in recognizing the differences, understanding the risks, and knowing when to seek medical attention.

Understanding the Common Cold and RSV

The common cold is usually caused by rhinoviruses and is relatively mild. RSV, on the other hand, is a specific virus that can lead to more serious respiratory illnesses, particularly in infants under 6 months and those with certain health conditions.

Symptoms of a Common Cold

  • Nasal Congestion and Runny Nose: These are typically the first signs of a cold.
  • Sneezing and Coughing: Mild to moderate coughing and sneezing are common.
  • Low-Grade Fever: Sometimes a cold can be accompanied by a slight fever.
  • Appetite Changes: Infants might eat less due to nasal congestion.

Symptoms of RSV

  • Persistent Coughing or Wheezing: A more persistent and severe cough is a hallmark of RSV.
  • Rapid or Difficulty Breathing: Watch for signs of labored breathing, such as flaring nostrils or visible retractions (skin pulling in around the ribs).
  • High Fever: RSV may cause a higher fever than a common cold.
  • Lethargy: Infants with RSV might be unusually tired and irritable.
  • Poor Feeding: Difficulty breathing can lead to challenges with feeding.

Risk Factors for Severe RSV

  • Age: Infants under six months are at higher risk.
  • Premature Birth: Premature babies have a higher risk due to underdeveloped lungs.
  • Underlying Medical Conditions: Conditions like heart disease or weakened immune systems increase the risk of severe RSV.
  • Exposure to Smoke: Secondhand smoke exposure can exacerbate respiratory illnesses.

When to Seek Medical Attention

It’s important to consult your pediatrician if:

  • Your infant is under three months old and shows signs of illness.
  • There’s rapid, labored breathing or prolonged coughing.
  • The baby is lethargic, not feeding well, or showing signs of dehydration (fewer wet diapers).
  • A fever over 100.4°F (38°C) in infants under three months or a high fever in older infants.

Prevention and Care

  • Hand Hygiene: Regular hand washing can prevent the spread of both colds and RSV.
  • Avoid Crowds: Keep infants away from crowded places during RSV season (fall to spring).
  • Clean Surfaces: Regularly disinfect surfaces and objects in your home.
  • Breastfeeding: If possible, breastfeeding can help bolster your baby’s immune system.


While colds and RSV can have overlapping symptoms, RSV tends to be more severe and requires closer monitoring. Understanding these differences and responding promptly to the signs of RSV can help keep your infant safe and healthy. Always err on the side of caution and consult with your pediatrician for any concerns about your baby’s respiratory health.
