Predictive Power Of Wastewater For Nowcasting Infectious Disease Transmission: A Retrospective Case Study Of Five Sewershed Areas In Louisville, Kentucky, Fayette Klaassen, Rochelle H. Holm, Ted Smith, Ted Cohen, Aruni Bhatnagar, Nicolas A. Menzies

Faculty Scholarship

Background: Epidemiological nowcasting traditionally relies on count surveillance data. The availability and quality of such count data may vary over time, limiting representation of true infections. Wastewater data correlates with traditional surveillance data and may provide additional value for nowcasting disease trends. Methods: We obtained SARS-CoV-2 case, death, wastewater, and serosurvey data for Jefferson County, Kentucky (USA), between August 2020 and March 2021, and parameterized an existing nowcasting model using combinations of these data. We assessed the predictive performance and variability at the sewershed level and compared the effects of adding or replacing wastewater data to case and death reports. …

Assessing Boil Water Notices As Health-Risk Communication: Risk Perceptions, Efficacy, And Compliance During Winter Storm Uri, Ashleigh M. Day, Sydney O'Shay, Khairul Islam, Matthew W. Seeger, Shawn P. Mcelmurry

Open Data at Wayne State

Winter Storm Uri was an extreme disaster that impacted much of the United States during February of 2021. Texas and Oklahoma were generally not prepared for such an event and experienced massive power grid failures. This led to cascading risks including water system disruptions and many boil water notices (BWNs). The breakdown of some communication channels and the inability to enact protective actions due to power outages, as well as travel limitations on public roads, complicated both dissemination and implementation. Under these conditions, a non-representative, cross-sectional, survey was collected to assess individuals experience BWNs and how perceived efficacy impacts compliance. …

The Detection Of Periodic Reemergence Events Of Sars-Cov-2 Delta Strain In Communities Dominated By Omicron, Claire E. Westcott, Kevin J. Sokoloski, Eric C. Rouchka, Julia H. Chariker, Rochelle H. Holm, Ray A. Yeager, Joseph B. Moore Iv, Erin M. Elliott, Daymond Talley, Aruni Bhatnagar

Faculty Scholarship

Despite entering an endemic phase, SARS-CoV-2 remains a significant burden to public health across the global community. Wastewater sampling has consistently proven utility to understanding SARS-CoV-2 prevalence trends and genetic variation as it represents a less biased assessment of the corresponding communities. Here, we report that ongoing monitoring of SARS-CoV-2 genetic variation in samples obtained from the wastewatersheds of the city of Louisville in Jefferson county Kentucky has revealed the periodic reemergence of the Delta strain in the presence of the presumed dominant Omicron strain. Unlike previous SARS-CoV-2 waves/emergence events, the Delta reemergence events were geographically restricted in the community …

An Assessment Of Disinfection-Related Water Chemistry At Public Pools And Spas In Louisville, Kentucky, Thomas Gerding, Tim Wilder, Jason W. Marion

EKU Faculty and Staff Scholarship

The growth in the number of pools to more than 7.4 million in the U.S. has been accompanied by a rise in recreational water illnesses (RWIs). Effective pool management, though, can mitigate RWI risks. Inadequate management presumably occurs more frequently where training is less formalized and/or pool operation is a minor aspect of the job of the responsible pool manager(s). During summer 2018, weekly evaluations were performed at public venues in Louisville, Kentucky. Disinfectant levels and other items were monitored and compared with venue-specific (pool or spa) criteria. Among 1,312 venue surveys, 1,173 (89.4%) met criteria and 139 (10.6%) did …

Outdoor Air Quality, Taylor Curley

Global Issues in Public Health

Outdoor air quality is a significant issue for the entire world. It affects any and all people, but is more of an issue in low-income countries and among people that are more susceptible to respiratory issues such as young children, pregnant women, the elderly, and people who already suffer from respiratory problems like asthma. Poor air quality is caused by the burning of fossil fuels which releases particles and chemicals into the air like carbon dioxide, particulate matter, and nitrogen to name a few. It can cause multiple health issues such as respiratory problems to people who are exposed to …

Indoor Air Quality: The United States, Paola Solano

Global Issues in Public Health

Indoor air quality is one of today’s most prevalent public health concerns. It is quite shocking to learn that almost all populations in the world can be affected. We oftentimes expect to be home and be safe, but our indoor environment can also be harming to our health. In certain regions, there is more pollution indoors than outdoors due to the surrounding environment. There exist numerous factors that can cause poor air quality. Some of the most common causes include mold, carbon dioxide, moisture damage, and other indoor air contaminants. Although alarming, there are many practices that can better the …

Water Scarcity: Sudan, Catherine Priebe

Global Issues in Public Health

Water scarcity is an environmental global problem that will only become more pressing as time goes on. It is a public health issue that affects every continent, although certain areas of the world are facing more serious water scarcity than others such as Sudan. Populations that are more vulnerable to the effects of water scarcity are the poor, women, children, and those living in areas of political unrest. For example, South Sudan’s urban water systems have been damaged during recent warfare. Water scarcity is also an issue that disproportionately affects women who are forced from a young age to travel …

Chad : Hepatitis E, Hanna Pegarsch

Global Public Health

Contaminated drinking water in Chad is the main source for a Hepatitis E outbreak, leading Chad citizens to develop severe illness including jaundice, liver-failure, miscarriage, and death. There are 0.4 physicians for every 10,000 people living in Chad needing healthcare. Of the citizens in Chad, only 42% have access to uncontaminated drinking water. With such a long incubation period for Hepatitis E, the citizens don’t know they are spreading the illness to the rest of their community. Even with the symptoms, the citizens don’t have the access or the capacity for treatment, making Hepatitis E an epidemic in Chad.

Agenda: Fracking, Water Quality And Public Health: Examining Current Laws And Regulations, Network For Public Health Law, American Society Of Law, Medicine & Ethics, Public Health Law Research Program

Fracking, Water Quality and Public Health: Examining Current Laws and Regulations (March 20)

Improved technology developments in directional drilling and hydraulic fracturing, more commonly known as "fracking," have resulted in an oil and gas production boom nationwide. Fracking involves pumping pressurized water, sand, and chemicals down wells to crack bedrock, freeing petroleum and natural gas. Wastewater discharges, hydraulic fracturing fluid releases, and other accidental spills pose potential water quality risks, sparking concern for public health.

This webinar will examine the laws and regulations governing water quality issues related to fracking, recent state court decisions affecting regulations, and implications for public health.

Pollution And Public Health In A Shrinking World: Concentrated Animal Feeding Operations As A Paradigm For Emergent Needs In Environmental And Public Health Policy, Leland Stillman

Self-Designed Majors Honors Papers

Environmental factors play a major part in human health. Environmental pollutants are often as poisonous to humans as the environment. Presently, much time and energy is dedicated to keeping pollution apart from human society, with varying success. But as global population densities rise, current levels of pollution will become inviable due to public health concerns. An emergent example of this is in the concentration of livestock operations. Recent changes in the structure of U.S. hog farming have resulted in an industry-wide shift from small or medium production farms to high capacity, “concentrated animal feeding operations” (CAFO). These operations have become …

Plymouth-Carver Sole Source Aquifer: Regional Open Space Plan, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

The second largest sole source aquifer in Massachusetts, the Plymouth-Carver Sole Source Aquifer (the Aquifer) covers 140 square miles underlying the towns of Plymouth, Carver, Kingston, Wareham, Plympton, Middleborough, and Bourne. The Aquifer contains over 500 billion gallons of fresh water (USGS 1992), and serves as a critical water resource for residential, commercial, and agricultural uses in the area. Though its resources are vast, they are not unlimited, nor are they unaffected by contamination.

On August 7, 1990, the Environmental Protection Agency (EPA) released a notice announcing that the Plymouth-Carver Aquifer satisfies all criteria for designation as a sole source …
