Respiratory syncytial virus (RSV) disease - new data needed to guide future policy

Area of Science:

• * Virology and Epidemiology
• * Public Health and Preventive Medicine

Background:

• * Respiratory Syncytial Virus (RSV) is a primary cause of lower respiratory infections in children globally.
• * RSV also contributes to wheeze in children and poses a significant disease burden in the elderly and adults with chronic conditions like COPD.
• * The pathogen incurs substantial healthcare and societal costs, yet understanding of RSV disease, particularly in adults, remains incomplete.

Purpose of the Study:

• * To highlight the critical need for enhanced understanding of RSV disease burden across all age groups.
• * To advocate for the establishment of widespread national sentinel surveillance systems for RSV.
• * To emphasize the importance of surveillance data for informing policy and decision-making regarding future interventions and vaccine prioritization.

Main Methods:

• * Discussion of the current gaps in large-scale RSV epidemiological data, particularly from diverse global settings.
• * Exploration of the necessity and potential frameworks for implementing national sentinel surveillance systems.
• * Analysis of the role of such data in guiding public health policy and immunization strategies.

Main Results:

• * Current understanding of RSV disease is limited, especially in adult populations.
• * Existing large-scale data are confined to a few countries, leading to underestimation of the pathogen's impact.
• * Development of candidate RSV vaccines is progressing, with expectations for near-term availability.

Conclusions:

• * Establishing comprehensive national sentinel surveillance systems for RSV is crucial.
• * Data generated from these systems will be essential for policymakers and advisory groups.
• * Informed decision-making is required to guide future priority setting for RSV prevention and control efforts.
