RSV epidemiology

Respiratory Syncytial Virus (RSV) is a common virus that infects the respiratory tract, especially in infants, young children, and older adults. It spreads easily through respiratory droplets from coughs or sneezes and can also survive on surfaces. Most people get infected at least once during childhood, often causing cold-like symptoms. RSV is a leading cause of bronchiolitis and pneumonia in infants and can lead to severe illness, especially in vulnerable groups. Seasonal in nature, RSV typically circulates during cooler months, with outbreaks varying by region and year. Prevention includes good hygiene and, for high-risk groups, preventive medication.
