Monitoring West Virginia Wastewater For Norovirus: A Test Case For Tracking Foodborne Illness Outbreaks In Rural Communities Using Wastewater, Haley M. Phillippi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Foodborne illnesses are a global public health challenge. Foodborne illnesses, like norovirus, often have a large disease and societal burden. Norovirus is a single-stranded, positive-sense RNA virus, with 10 identified genogroups (GI-GX). Genogroups GI and GII are responsible for nearly all human cases of acute gastroenteritis worldwide. In the United States, HuNoV is not notifiable case-by-case. Instead, outbreaks are reported to national surveillance systems when two or more cases are epidemiologically linked. Most norovirus outbreaks occur during Winter to early Spring, however, certain individuals may still shed and transmit the virus without being detected or reported. Wastewater monitoring is a …
