Infectious Agents

Viral and bacterial infections are known to cause a number of different malignancies in populations worldwide. DCEG carries out multidisciplinary studies of carefully selected populations in the United States and abroad, with the goal of clarifying the relationship of infectious agents, especially viruses, to human cancer and other conditions. Recent research has concentrated on human retroviruses (HIV-1), with additional studies on human papillomaviruses (HPV), hepatitis viruses, and papillomaviruses.

In response to the SARS-CoV-2 pandemic, a collaborative group of epidemiologists, geneticists, and data scientists accelerated the discovery of outcomes and risk factors for patients infected with SARS-CoV-2. Learn more about our COVID-19-related research.

Hepatitis Viruses


  • Hepatitis Viruses and Liver Cancer 
    DCEG investigators conduct interdisciplinary collaborative studies that integrate epidemiology, virology, and human genetics to study chronic hepatitis virus infection, the cause of most hepatocellular carcinoma (HCC), the third leading cause of cancer mortality worldwide.

Human Papillomavirus (HPV)

Human Immunodeficiency Virus (HIV)

  • HIV/AIDS Cancer Match Study
    HIV/AIDS cancer match study examines cancer risk among people living with HIV infection in the United States.
  • EBV and Genetics in AIDS NHL
    DCEG investigators seek to clarify the roles of the Epstein-Barr virus (EBV) and common variants in genes controlling immunity and inflammation on the risk of AIDS-related non-Hodgkin lymphoma.
