The Impacts Of Trust In The Time Of Covid-19, Hannah Temes

Graduate Research Theses & Dissertations

Over 350,000 Americans died from COVID-19 in 2020, the first year of the pandemic. Federal health institutions such as the Center for Disease Control and Prevention (CDC) and the Department of Human Health Services (DHHS) established guidelines for the public to follow during the pandemic. However, trust in these institutions varied resulting in differing public response —some followed the COVID protocols while others did not. It has been argued that when someone’s self-interest is at risk, they need to trust the government to take care of them. During the COVID-19 pandemic, a time when public health and self-interest were intertwined, …

Rbd Amplicon Sequencing And Evolutionary Analysis Of Sars-Cov-2 Variants From Wastewater Samples, Xingwen Chen, Chunfu Zheng, Fuqing Wu

Faculty, Staff and Student Publications

The surveillance of SARS-CoV-2 is significantly limited by the presence of numerous variants with distinct behaviors driven by rapid evolution. Although the conventional clinical genome sequencing method provides comprehensive data, it has limitations in capturing the epidemiological dynamics of the variants circulating in the community. In this chapter, we describe a protocol using RBD amplicon sequencing of wastewater samples. We present the detailed experimental procedure for wastewater sample processing, robust nested-PCR-based amplification of the target RBD sequence, and library preparation. Moreover, we describe a general pipeline of sequencing data processing and interpretation, showing the epidemiological and evolutionary trends of SARS-CoV-2 …
