This project will provide information on the prevalence and intensity of gastrointestinal parasites in long-tailed macaques, local residents (who have been directly or indirectly exposed to macaques and their wastes) and environmental samples, possible cross transmission of zoonotic parasites, and evaluation of different risk factors associated with the occurrence of gastrointestinal parasites in human-macaque interface. To have substantial knowledge and better understanding on the transmission dynamics of parasites in human-macaque interface are essential in the mitigation of possible zoonotic/anthroponotic transmission of parasitic infection in the area. The results of this project will also contribute to the possible recommendation of policies that will help promote public health protection, reduction of parasitic infection risks to macaques, tourists and local residents and to have sustainable eco-tourism in the study areas. spots. Information generated from this study will also be used to formulate the Vulnerability Index of tourist areas in terms of zoonosis and conflict.
