Respiratory Syncytial Virus (RSV) is a highly contagious viral infection primarily affecting the respiratory system. It is a common cause of respiratory illness in young children and infants, and it typically spreads through tiny droplets when an infected person coughs or sneezes. While most cases of RSV are mild and resemble a common cold, the virus can lead to more severe respiratory complications, especially in vulnerable people with pre-existing conditions. Recognizing the warning signs of RSV is crucial for early detection and timely intervention to ensure the well-being of young children. Persistent cough RSV in children comes with the hallmark symptom of a worsening, persistent cough. Something that might start as a mild but dry cough slowly progresses into a wet cough with mucus production. The change occurs as the condition advances into a more severe infection. Children who are affected by the condition may have difficulty clearing the mucus in their lungs. This can prolong the coughing episodes, as peristaltic movement is essential to eliminating mucus from the system. In some cases, the episodes of coughing, forced or otherwise, can be serious enough to disrupt the child’s sleep cycle. Wheezing and breathing difficulties Another common symptom children face due to an RSV infection is the constriction of their airways.
