Abstract：Objective To analyze the spatiotemporal distribution characteristics of honey-induced poisonings in Yunnan Province from 2005 to 2013 so as to provide scientific evidence for implementing targeted control measures. Methods The data about the reported honey-induced poisoning events in each county (district) of Yunnan Province during 2005-2013 were descriptively analyzed, and SaTScan software was used for spatial clustering analysis. Results A total of 12 events of honey-induced poisoning were reported in Yunnan Province during 2005-2013, which resulted in 75 poisoning cases and 18 deaths. All the poisoning events occurred from May to August, of which 11 poisonings happened in the west of Yunnan Province and only 1 in the east region. Except for 1 poisoning in 2013 was confirmed to be caused by Tripterygium hypoglaucum through pollen analysis, the causes of other 11 poisonings remained unknown. A clustering district, which centered at north of latitude 24.8°N and east of longitude 97.9°W, within a radius of 251.2 km, was detected by SaTScan, and the risk of honey-induced poisoning of this district was significantly higher than those of other districts(RR=49.85,LLR=15.57, P<0.05). Conclusions There exists a seasonal high-incidence district of honey-induced poisoning district in the west of Yunnan Province. The cause of the poisoning may be associated with poisonous nectar plants like Tripterygium hypoglaucum; and hence, the targeted countermeasures should be taken.
