Research Interests

Infection and tolerance mechanism of malaria, Epidemiology of Infectious disease

1)Introduction of new theoretical epidemiology and medical statistical method in regional specificity research of malaria
The incidence of malaria patients in Sarawak, Malaysia is less than that of malaria in adjacent Indonesia, but about 3000 cases of infectious cases have been reported annually and about 15 people have died. In this study, we analyzed the relationship between changes in the dynamics of malaria patients and various region-specific factors, including climate and race, and examined the preventive method which can be judged effective from the viewpoint of medical economics and medical policy . The applicant has already carried out research focusing on accumulation in epidemiological research related to the subject matter. In this study, considering confounding factors related to region specificity, by introducing a econometric analysis method into conventional epidemiological research, It is possible to introduce analysis of spatiotemporal level which has not yet been implemented in the research field of epidemic infectious diseases

2) Molecular epidemiological study on the development of drug-resistant protozoa by trafficking and use of placebo near the border

In the Southeast Asian border area, placement and use of placebo frequently occurred, and due to the use of placebo, patient death and resistant type protozoa occurred. In this study, in addition to the above-mentioned research, we investigate the influx of placebo into residents who are economically poor and the statistical correlation and cause-and-effect relationship of development and diffusion of drug resistant type malaria by molecular epidemiological method.
