Respiratory syncytial virus (RSV) is a human-specific microbe that causes infections similar to the common cold and flu. This virus is present worldwide and follows a seasonal cycle. It is most active between autumn and early spring, with a peak in mid-winter.
It mainly affects young children and the more fragile elderly. In children under the age of one, it is the main cause of bronchial infections (bronchiolitis). After the age of two, almost all children will have been infected at least once.
For most people, the infection causes few symptoms; however, in certain populations, it can be severe, leading to breathing difficulties and even cardiorespiratory arrest.
It’s important to take steps to prevent infection.
