I am interested in emerging infectious diseases triggered by human activity. For example, in Malaysia, the clearing of tropical forests to build numerous pig farms led to the emergence of the Nipah virus in 1997. Wild bats, which were carriers of the unknown virus, came into contact with pigs, and the virus was transmitted to humans through pigs, resulting in numerous deaths. As humans continue to impact wildlife habitats, the occurrence of emerging infectious diseases is increasing worldwide. How can humans, animals, and the environment coexist in a healthy balance? I am collaborating with researchers in Southeast Asia, a region identified as a hotspot for emerging infectious diseases, to study pathogens lurking in animals and the environment.
