Respiratory Syncytial Virus (RSV)

Respiratory Syncytial Virus (RSV) is a highly contagious virus that causes mild cold-like symptoms in most people, but it can lead to severe respiratory illness in infants, the elderly, and those with weakened immune systems. RSV is the most common cause of lower respiratory infections in infants and can result in hospitalization. It is especially prevalent in children, with almost all young children being infected by the age of 2. This virus is seasonal, typically starting in the fall and peaking in the winter.
