Introduction: The human respiratory syncytial virus (hRSV) is one of childhood diseases' most common respiratory pathogens and is associated with lower respiratory tract infections. The peak in disease that this virus can elicit during outbreaks is often a significant burden for healthcare systems worldwide. Despite theapproval of treatments against hRSV, this pathogen remains one the most common causative agent of infant mortality around the world.
Areas covered: This review focuses on the key prognostic and immunomodulatory biomarkers associated with hRSV infection, as well as prophylactic monoclonal antibodies and vaccines. The goal is to catalyze a paradigm shift within the scientific community toward the discovery of novel targets to predict the clinical outcome of infected patients, as well as the development of novel antiviral agents targeting hRSV. The most pertinent research on this topic was systematically searched and analyzed using PubMed ISI Thomson Scientific databases.
Expert opinion: Despite advances in approved therapies against hRSV, it is crucial to continue researching to develop new therapies and to find specific biomarkers to predict the severity of infection. Along these lines, the use of multi-omics data, artificial intelligence and natural-derived compounds with antiviral activity could be evaluated to fight hRSV and develop methods for rapid diagnosis of severity.
