SPPH 503 Epidemiological Methods II

Nazurl Islam, PhD Student

Research Interests: 

  • Hepatitis B and C epidemiology
  • Unsafe medical injections and blood borne pathogens
  • Influenza epidemiology/immuno-epidemiology and vaccine effectiveness
  • Socio-economic disparities in health
  • Nutrition transition in developing countries
  • Global and international health


Current Research Projects:

Hepatitis Education Canada

The project investigates factors influencing attendance for hepatitis C care. Based on research findings, the program develops culturally and linguistically appropriate hepatitis C education resources for the population, hepatitis patients and health care providers. It covers topics such as prevention, testing, care and support, treatment and living with hepatitis. Resources include e-learning course, print material, videos, and a website (http://hepatitiseducation.ca ) that bring everything together with an easily accessible navigation hub on the front page for various cultural and linguistic groups.
