Earlier and prolonged respiratory syncytial virus (RSV) seasons in young children compared to adults: implications for prevention in infants

Respiratory syncytial virus (RSV) is a major health concern, especially for young children and older adults. In this study, we explored whether different age groups changed the timing of RSV season. This is important because public health guidelines, hospital preparedness, and preventive strategies like antibody prophylaxis and vaccination rely on accurate RSV season timing. By showing how RSV trends differ by age, our findings can help improve seasonality responses and ensure that preventive measures reach high-risk groups, especially infants, at the right time.
