RSV (respiratory syncytial virus) is one of the most common viruses that cause coughs and colds. It circulates widely in the UK in the autumn and winter months, peaking in December. Almost all children are infected with the virus by the time they’re two years old. RSV may cause a cough or cold in children and adults, but in young children it is the main cause of bronchiolitis. In fact, it’s the most common cause of bronchiolitis in children aged under two. In this episode, our health lead Amanda explains how to spot the signs of RSV and what you can do to alleviate them, including when to get advice from your doctor or help from emergency services.
