Introduction: The human respiratory syncytial virus (hRSV) is the leading cause of respiratory infections in children, older adults, and patients with comorbidities. Since the hRSV discovery, multiple efforts have been made to generate therapies that control the devastating effects on the population at risk in winter. Areas covered: This article describes the development of different drugs and treatments approved for use in the risk-population against hRSV infection. In addition, an exhaustive bibliographical review is presented here describing new candidate molecules under evaluation and showing promising results in different assays in animal models and clinical studies. Additionally, we highlight antiviral molecules, monoclonal antibodies, and nanobodies among the new candidate treatments. Expert opinion: hRSV is a major burden for the health systems, promoting their collapse worldwide. Therefore, developing new therapies is an essential goal to decrease hospitalization rates caused by hRSV infection in high-risk populations. For this, injecting resources and exploring new targets in addition to the F protein is an interesting alternative to achieve this goal.
