PHO Rounds: Mpox: Outbreak, Response, and Vaccine Effectiveness

In the Spring of 2022, an explosive global epidemic of mpox infection emerged, primarily in gay, bisexual and other men who have sex with men (GBM). Ontario was among the first jurisdictions to see large numbers of cases, and a variety of civil society, clinical, public health and research activities rapidly mobilized in response. This session will review current knowledge about the epidemic, including key epidemiologic and clinical features while further highlighting emerging findings about medical countermeasures including tecovirimat for therapy and Imvamune™ vaccine for prevention. A critical aspect of the response that will be highlighted is the importance of grounding public health work in community engagement principles.

Intended audience: Medical Officers of Health/Associate Medical Officers of Health (MOH/AMOHs), Public Health Unit (PHU) staff (particularly those working in Sexually Transmitted Blood Borne Infections (STBBI) and Infectious Diseases), Researchers, Physicians, Nurses, Epidemiologists and Community Health Staff

By the end of this session, participants will be able to:

  • Describe the evolving epidemiology of mpox in Ontario and globally with a focus on the 2022 outbreak
  • Identify the key clinical characteristics of mpox infection
  • Discuss recent evidence and advances in our understanding of medical countermeasures including antivirals and vaccines against mpox
