Hepatitis Virus (HBV, HCV, HAV, and HEV), epidemiology, disease control and prevention, theoretical epidemiology (Bayes and Markov), immune analysis of virus, effectiveness evaluation of cancer screening, blood programme and blood donation promotion, big data analysis and data health, medical statistics, global epidemiology

【Recent highlights】
・We estimated the number of HBV and HCV carriers in Japan and reported that it decreased to 2.1 ~2.8 million people in 2011 in comparison to 3~3.7 million people in 2000.
・We conducted epidemiological research to grasp the situation of hepatitis virus infection in Cambodia at Siem Reap Province. We started this research in 2009. Now, we are planning to conduct a population-based survey in Cambodia in collaboration with WPRO (WHO Western Pacific Region), CDC/USA (Centers for disease control and prevention), and the Ministry of Health of Cambodia.
・MPH (Master of Public Health) course has opened since 2015. This department provides lectures on Epidemiology and Biostatistics in MPH.

Profiles of Faculty and Research Scholars

This department provides training in epidemiology, health statistics, biostatistics, preventive medicine and health promotion, infection control, screening, food hygiene, environmental hygiene, medical ethics, and global hygiene. Especially, the aim of epidemiological training leads to disease prevention and control. We lecture theory and methodology to achieve this aim.

We practice many exercises including basic biostatistics because epidemiology is important in not only social medicine and but also clinical medicine. These exercises are linked to Epidemiology and Biostatistics course in MPH (Master of Public Health). MPH course has opened since 2015. The goals in this course are generating hypotheses to research questions and choosing research design. In addition, students are trained in conducting analysis, epidemiological evaluation, and statistical analysis appropriate to each data set. Furthermore, students participate to themes listed in Research section. Sometimes trend diseases are added as themes.  

We are conducting viral hepatitis sero-epidemiological research with international cooperation. Therefore students will be able to learn in international environment. Students can also learn techniques of laboratory experiment.

There are many applicants who are graduate students working in various fields in this department. Therefore students are expected to be disease control leaders in their own fields after their graduation.
