During the coronavirus disease 2019 (COVID-19) pandemic, navigating the implementation of public health measures in a politically charged environment for a large state entity was challenging. However, Louisiana State University (LSU) leadership developed and deployed an effective, multi-layered mitigation plan and successfully opened in-person learning while managing cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the fourth surge. We describe the plan to provide a framework for other institutions during this and future responses. The goals were 3-fold: maintain a quality learning environment, mitigate risk to the campus community, and ensure that LSU operations did not contribute to …

Social Media Use And Covid-19: A Cross-Sectional Study Examining Health Behaviors, Knowledge, And Mental Health Among University Of Nevada, Reno Students, Molly M. Hagen, Sarah Y.T. Hartzell, Paul G. Devereux

Health Behavior Research

Reliance on social media for health information is widespread, yet impacts of social media use (SMU) on health behaviors during infectious disease pandemics are poorly understood. We used a random sample from a university student directory to invite students to take a cross-sectional online survey during the coronavirus pandemic. Survey questions assessed adherence to public health guidelines, knowledge of COVID-19/SARS-CoV2, and mental health symptoms. Students were classified based on their level of SMU for information on COVID-19 as: (1) none, (2) some use, or (3) main source. Weighted regressions were used to relate SMU to adherence (five-point scale) and knowledge …

Mathematical Models Of Covid-19, Kate Faria

Honors Program Theses and Projects

For more than a year, the COVID-19 pandemic has been a major public health issue, affecting the lives of most people around the world. With both people’s health and the economy at great risks, governments rushed to control the spread of the virus. Containment measures were heavily enforced worldwide until a vaccine was developed and distributed. Although researchers today know more about the characteristics of the virus, a lot of work still needs to be done in order to completely remove the disease from the population. However, this is true for most of the infectious diseases in existence, including Influenza, …


Covid-19 Viral Testing Disparities In Los Angeles City, Laura Cyphers Dec 2020

Covid-19 Viral Testing Disparities In Los Angeles City, Laura Cyphers

Student Scholar Symposium Abstracts and Posters

Hispanic and Black communities have been disproportionately impacted by COVID-19-related morbidity and mortality (California Department of Public Health, 2020). Inequitable access to viral testing resources may have exacerbated these COVID-19-related racial and ethnic health disparities. For example, reports from the Los Angeles Department of Public Health revealed glaring viral testing disparities in April 2020 (early pandemic), with predominantly White communities in Los Angeles County receiving 65% more tests than Hispanic and Black communities. In response, California statewide testing was expanded for communities of color (Vann et al., 2020). To investigate access to viral testing in Los Angeles City, the current …

The Covid-19 Pandemic And The Power Of Numbers, Jessica Ancker May 2020

The Covid-19 Pandemic And The Power Of Numbers, Jessica Ancker

Numeracy

The COVID-19 pandemic has produced a deluge of news coverage of quantitative concepts. In this viewpoint, we provide examples of effective and poor quantitative communication by the professional news media as well as social media communicators. Effective examples include a number of online animations and engaging interactive simulations. Examples of poor quantitative communication include the widespread reporting of raw numbers rather than rates, failing to address uncertainty, not providing sufficient context for numbers, and not discussing the implications of false negative and false positive diagnostic test results. Educators can draw from this body of news to develop compelling quantitative literacy …

The Current State Of Migrant Health In Morocco: Pre-And Peri-Covid-19 Pandemic, Layla Babahaji

Independent Study Project (ISP) Collection

In the early 21st century, Morocco transitioned from being a predominantly transit migration country into both a transit and destination country for migrants. In 2013, the Moroccan government took significant steps to adapt the healthcare system in better integrating migrants in its policies. The government implemented the National Strategy on Immigration and Asylum that improved access to public health care for migrants. Recently, in March of 2020, Morocco declared a state of medical emergency due to the current COVID-19 pandemic that continues today. This paper addresses the effects of the COVID-19 pandemic on the current state of migrant health in …


The Problem With Relying On Profit-Driven Models To Produce Pandemic Drugs, Ana Santos Rutschman Jan 2020

The Problem With Relying On Profit-Driven Models To Produce Pandemic Drugs, Ana Santos Rutschman

All Faculty Scholarship

The longstanding problems of relying on a market response to a pandemic are becoming readily apparent in the United States, which has quickly become the epicenter of the COVID-19 outbreak. The problems are particularly pronounced in pharmaceutical markets, where we are pinning our hopes for both cures and vaccines. In previous work we have shown how characteristics of healthcare markets in the United States create a divergence between the private incentives of for-profit companies and public health needs, leading to sub-optimal health outcomes in what is a uniquely market-driven healthcare system. In this Essay, written as the COVID-19 pandemic unfolds, …


Hiv/Aids: Nigeria, Lauren Tropinski Jan 2018

Hiv/Aids: Nigeria, Lauren Tropinski

Global Issues in Public Health

Nigeria has one of the largest prevalence rates of HIV infections in Africa. HIV is a communicable disease that is transmitted by bodily fluids through unprotected sex, using contaminated needles, or mother to child. The most affected populations include heterosexuals who have unprotected sex, followed by sex workers, and men who have sex with men. People will experience three stages of HIV before the last stage referred to as AIDS. Rapid diagnostic tests are used to diagnose the disease. There is no cure for HIV/AIDS. However, people with HIV are given antiretrovirals to keep HIV at a low level throughout …


Chad : Hepatitis E, Hanna Pegarsch Jan 2017

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.

Evaluation Of The Pilot Program, Pediatric Early Warning Sentinel Surveillance Program (Pewss), And Its Efficacy In Monitoring Pediatric Illness In Clark County, Nevada, Michelle Lee Lutman

UNLV Theses, Dissertations, Professional Papers, and Capstones

The influenza outbreak that occurred during 2009 stimulated the formation of several surveillance programs throughout the country. The majority monitor only influenza; however, there are several other circulating respiratory pathogens, especially within the pediatric community. These other respiratory pathogens cause a variety of illnesses, such as bronchitis, pneumonia, croup, etc. Prior research has provided the medical community with valuable information about respiratory illnesses, especially those which afflict pediatric patients. Areas of knowledge including seasonality, demographics, signs and symptoms, prevention measures, and pathogenicity, have been greatly expanded over the years. This information has been of tremendous help to the medical community …


Acquired Immuno-Deficiency Syndrome (Aids) And Human Immuno-Deficiency Virus (Hiv) In Nevada – Annual Surveillance Report (1999), Mary Guinan, Nancy Kreher, Drew Mather, Wei Yang Sep 2001

Acquired Immuno-Deficiency Syndrome (Aids) And Human Immuno-Deficiency Virus (Hiv) In Nevada – Annual Surveillance Report (1999), Mary Guinan, Nancy Kreher, Drew Mather, Wei Yang

Public Health Faculty Publications

Background:

Acquired Immuno-Deficiency Syndrome (AIDS) is the most severe manifestation of Human Immunodeficiency Virus (HIV) infection. AIDS was first reported in the world in 1981 by the Centers for Disease Control and Prevention. Statewide surveillance for AIDS was begun in 1982. Because the cause of AIDS was unknown at that time, the surveillance case definition included many opportunistic infections and tumors. Persons with AIDS were noted to have abnormalities in their immune system that left them susceptible to certain infections. As more information became available, the AIDS surveillance case definition was modified.

In 1984, HIV was found to be the …
