PHS Monday Seminar- Karli Hochstatter, PhD: “Detecting Hepatitis C Virus Transmission Clusters among Key Affected Populations in Wisconsin Using Global Hepatitis Outbreak Surveillance Technology”

September 9 @ 5:00 pm - 6:00 pm


Recent outbreaks of hepatitis C virus (HCV) among people who inject drugs demonstrate the need for novel strategies to identify individuals at highest risk and community response models that can quickly interrupt transmission. Global Hepatitis Outbreak Surveillance Technology (GHOST) is a public health tool that uses next-generation sequencing data to detect genetic linkages between HCV-infected individuals and identify transmission clusters. Expanded use of GHOST may advance prevention efforts by enhancing the ability of health departments to conduct molecular surveillance and efficiently target resources. This seminar will include a presentation of the methodology for identifying high-risk individuals and detecting HCV transmission clusters, a description of the characteristics of transmission clusters in Wisconsin identified to date, and a discussion of how GHOST can be used to advance HCV elimination efforts.
