Abstract:
Objective To understand the application value of spacial clusters detection of human schistosomiasis epidemic,based on small scale level in heavy mountainous and hilly endemic areas, Songzi County,Hubei Province,China. Methods Positive results of human serological detection antibody titer equal or above 80,and positive schistosomiasis cases of fecal examination from 2016 to 2018 as research object in Songzi County.The flexible irregular space scan statistics was used to analyse the spatial clustering analysis of human schistosomiasis epidemic in the heavy mountainous and hilly endemic areas, setting parameter K=2 ,K=6 or K=10, respectively,based on small scale of village level in Songzi County. Results There was none positive schistosomiasis cases of fecal examination in Songzi County from 2016 to 2018.The number of human serological detection antibody titer equal or above 80 were 74, 206, 83, from 2016 to 2018，respectively.There was spatial clusters of positive of human serological detection antibody titer equal or above 80 for schistosomiasis cases in the county from 2016-2018. Areas of flexible irregular space scan statistic in cluster detection changing with the change of different K values. Under different parameters of flexible irregular space scan statistic results show that the most likely cluster of 40 endemic villages in three towns,inculding Laocheng town,Chendian town and Wangjiaqiao town were the prominent. Conclusion There are spatial clusters of human schistosomiasis based on small scale of village level by flexible irregular space scan statistic in mountainous and hilly endemic areas, Songzi County,Hubei Province.Therefore,the monitoring and control of schistosomiasis should be consolidated in the future,in order to achieve schistosomiasis elimination in Hubei Province at an early date.
