Attention should be paid to the detection and surveillance of human respiratory syncytial virus

Abstract

Human respiratory syncytial virus (HRSV) is the main pathogen of severe lower respiratory tract infection in infants and young children. It seriously endangers children's health. In recent years, great breakthroughs have been made in the research and development of HRSV vaccines and antibody-based biological products. The research and development and use strategies are inseparable from the monitoring of HRSV prevalence and virus variation characteristics. The World Health Organization (WHO) pays great attentions to the surveillance of HRSV epidemiology and virus variation characteristics, but China lacks national level and multi-center HRSV surveillance data, the surveillance case definitions used by various laboratories are inconsistent, and the detection and surveillance methods of HRSV are not unified. Results from different laboratories are difficult to be compared and analyzed. Therefore, it is urgent to establish a nation-wide HRSV surveillance network in China, and to persistently monitor the epidemic characteristics and virus variation characteristics of HRSV by using standardized HRSV detection methods and surveillance guideline, so as to provide basic scientific data for the research and development, use and evaluation of monoclonal antibodies and vaccines.
