Emerging Threats Epidemiology Group (ETEG)

eteg-logo-lg

The Emerging Threats Epidemiology Group (ETEG) focuses on epidemiologic aspects of health security risk, oriented towards impact on patient and community centered outcomes. With work streams that range from studies in the field, clinic, or laboratory to policy discernment and risk management, ETEG seeks to consistently generate actionable public health knowledge. The ETEG works with a diverse array of partners and is always looking for new opportunities for collaboration.
