目的探索雷州半岛鼠形动物鼠疫血清间接血凝(IHA)监测最佳时期。方法用圆形分布法对1973-2015年雷州半岛鼠疫监测数据进行统计分析。结果在雷州半岛家鼠鼠疫疫源地,鼠形动物鼠疫血清间接血凝最有效检出时点在11月28~29日,50%发生在10月~次年1月、75%集中在8月~次年3月之间;其中黄胸鼠最有效检出时点在11月18~19日,黄毛鼠在10月11~12日,臭鼩鼱在12月26~27日。结论雷州半岛鼠形动物鼠疫血清监测最佳时期在11~12月。
Objective To explore the best period for the monitoring of serum indirect hemagglutination (IHA) in rat-like animal plague in Leizhou peninsula. Methods The circular distribution method was used to analyze the surveillance data of plague in Leizhou peninsula from 1973 to 2015. Results The most effective detection of indirect hemagglutination of murine plague serogroups was found on November 28-29 in 50% of the plague foci of Leizhou Peninsula, 50% occurred in October-January of the following year, 75% of which were concentrated in 8 Month to March next year; among them, the most effective detection of Rattus flavipectus is at November 18-19, Rattus rat at October 11-12, Smelly mite at December 26-27. Conclusion The best period for serum monitoring of rat-type plague in Leizhou Peninsula is from November to December.
