R.E. Hengsterman RN, BS, MA MSN, M.E. 

Course Overview

This course provides an in-depth exploration of norovirus, covering its virology, transmission routes, pathophysiology, epidemiology, and clinical management. Participants will gain a comprehensive understanding of the challenges posed by norovirus outbreaks in healthcare facilities, long-term care settings, and community environments. 

The course explores the immune response to norovirus infection, diagnostic approaches, differential diagnosis, and the latest research on potential therapeutic and preventive strategies, including vaccine development and antiviral treatments. Learners will gain insight through case studies and clinical reasoning to assist in diagnosing and managing norovirus infections across distinct vulnerable populations, including high-risk groups such as older adults, immunocompromised individuals, and young children.
