DiscussionSchistosomiasis remains a major public health
problem in some endemic communities in the Philippines. The major endemic areas
are located in agricultural areas and marshlands in the Southern regions in the
country. Spatial analytical techniques are often used in epidemiology to
identify spatial clusters in disease regions. This study assessed the spatial
distribution of schistosomiasis and explores high-risk areas in Southern
Mindanao to provide guidance on schistosomiasis control in the region.
In this study, spatial distribution using QGIS was
utilized to describe and map spatial clusters and areas where human Schistosoma
japonicum infection is prevalent. In addition, logistic regression
model was used to determine the characteristics of spatial distribution.
Results revealed that high prevalence was observed in areas near irrigations
and marshlands. In addition, the knowledge, perception, and practice such as
playing and working in the rice field, presence of farm animals, and housing
management of water buffalo showed significant associations. The findings
indicated that spatial surveillance of S. japonicum transmission
plays a significant role in schistosomiasis control. Timely and integrated
prevention should be continued, especially in marginalized endemic communities.
