Abstract: In order to understand the research status and focus of porcine reproductive and respiratory syndrome(PRRS), we chose papers in CNKI database including in SCI, EI, core source journals and CSSIC database from 2004 to 2015. The study analyzed and compared the pubtime, subject, journals distribution, research level distribution of the papers, and source of fund projects, authors, research institutions and  key words frequency. The results showed that the porcine reproductive and respiratory syndrome-related research papers focused on the animal husbandry and veterinary medicine, biology and other disciplines; in 2008, the related research papers published the largest number; the core journal of the "Progress in Veterinary Medicine" published most papers on PRRS, animal husbandry and veterinary, animal-related journals were the main journals published PRRS research papers; researchers mostly concentrated in major research institutes and universities, the largest number of papers published by the research institutions was Nanjing Agricultural University; porcine reproductive and respiratory evolution syndrome virus, porcine reproductive and respiratory syndrome virus, virus detection, virulence, dissemination mechanisms and PRRS vaccine, effective prevention and control of PRRS were currently research areas hotspots. The most effective means of prevention and control of PRRS is vaccine, but the traditional control methods for emerging variation PRRS virus and does not offer sufficient protection, enhance monitoring PRRS virus genetic variation, master of virus variation trend of the virus is the current frontiers of PRRS research, and developing of more effective vaccines will be the focus in the future research.
