Age-Dependent Risk of Bronchial Asthma Exacerbation in Respiratory Syncytial Virus Co-infection

RSV co-infection with other respiratory viruses increases the risk of BA exacerbation, especially in age under 6 years patients. Given the proven efficacy of RSV vaccine for adults and monoclonal antibody for high-risk children in preventing RSV-related lower respiratory tract disease, RSV-targeted prevention strategies for younger children appear effective in reducing respiratory disease burden.
