Respiratory Syncytial Virus (RSV) is one of the most common viruses affecting young children during the winter months. While many cases resemble a common cold, RSV can lead to serious respiratory illness in babies, premature infants, and children with underlying health conditions. Paediatrician Dr Mark Moodley joins us to explain what RSV is, how to recognise the warning signs, which children are most at risk, and when parents should seek medical care. He also shares practical advice on treatment, prevention, and the key steps families can take to help keep little ones healthy this winter.
