Preliminary investigation on the carriage status of the novel bunyavirus mong animals and ticks in Beijing area

Objective To investigate the carriage of the novel Bunyavirus among rodents,canines and ticks in Beijing area,to explore the animal host and transmission vector which possibly exists in the nature for the novel Bunyavirus,analyze the possibility of natural epidemic focus place existence in Beijing area for the novel Bunyavirus,and the risk of its transmission,in order to provide the background data and theoretical basis for the prevention of fever with thrombocytopenia syndromes in Beijing.Methods Examine the rodents‘and canines'blood sera and ticks gained in five suburb counties of Beijing in 2010 surveillance for the novel Bunyavirus RNA using real-time RT-PCR method to investigate the virus carriage situation.Results 100 animal blood sera,including 19 canines'and 81 rodents'sera samples and 97 ticks tested were all negative for the novel Bunyavirus RNA.Conclusion The animal host of the novel Bunyavirus in nature needs to be further identified.No carriage of this novel Bunyavirus was found in rodents,canines and ticks in 2010 surveillance in Beijing area,therefore whether there is any natural epidemic focus place in Beijing area for this novel Bunyavirus still needs further investigation and study.And even if rodents are the host of this virus,the risk of the transmission for this novel Bunyavirus is also lower in Beijing area because of the low rodent’s density.
