To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1-11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common …

Evaluation Of A Targeted Covid-19 Community Outreach Intervention: Case Report For Precision Public Health, Isela De La Cerda, Cici X Bauer, Kehe Zhang, Miryoung Lee, Michelle Jones, Arturo Rodriguez, Joseph B Mccormick, Susan P Fisher-Hoch

Journal Articles

BACKGROUND: Cameron County, a low-income south Texas-Mexico border county marked by severe health disparities, was consistently among the top counties with the highest COVID-19 mortality in Texas at the onset of the pandemic. The disparity in COVID-19 burden within Texas counties revealed the need for effective interventions to address the specific needs of local health departments and their communities. Publicly available COVID-19 surveillance data were not sufficiently timely or granular to deliver such targeted interventions. An agency-academic collaboration in Cameron used novel geographic information science methods to produce granular COVID-19 surveillance data. These data were used to strategically target an …

Beyond Scale-Free Networks: Integrating Multilayer Social Networks With Molecular Clusters In The Local Spread Of Covid-19, Kayo Fujimoto, Jacky Kuo, Guppy Stott, Ryan Lewis, Hei Kit Chan, Leke Lyu, Gabriella Veytsel, Michelle Carr, Tristan Broussard, Kirstin Short, Pamela Brown, Roger Sealy, Armand Brown, Justin Bahl

Journal Articles

This study evaluates the scale-free network assumption commonly used in COVID-19 epidemiology, using empirical social network data from SARS-CoV-2 Delta variant molecular local clusters in Houston, Texas. We constructed genome-informed social networks from contact and co-residence data, tested them for scale-free power-law distributions that imply highly connected hubs, and compared them to alternative models (exponential, log-normal, power-law with exponential cutoff, and Weibull) that suggest more evenly distributed network connections. Although the power-law model failed the goodness of fit test, after incorporating social network ties, the power-law model was at least as good as, if not better than, the alternatives, implying …

Life In A Time Of Covid: Retrospective Examination Of The Association Between Physical Activity And Mental Well-Being In Western Australians During And After Lockdown, Ben Piggott, Paola Chivers, Kiira Karoliina Sarasjärvi, Ranila Bhoyroo, Michelle Lambert, Lynne Millar, Caroline Bulsara, Jim Codde

Research outputs 2022 to 2026

Background: The aim of this study was to examine physical activity and sedentary behaviours during Western Australia’s COVID-19 lockdown and their association with mental well-being. Methods: Participants completed activity related questions approximately two months after a three-month lockdown (which formed part of a larger cross-sectional study from August to October 2020) as part of a 25-minute questionnaire adapted from the Western Australia Health and Well-being Surveillance system. Open-ended questions explored key issues relating to physical activity behaviours. Results: During the lockdown period, 463 participants (female, n = 347; 75.3%) reported lower number of active days (W = 4.47 p < .001), higher non-work-related screen hours per week (W = 11.8 p < .001), and higher levels of sitting time (χ2=28.4 p <. 001). Post lockdown body mass index was higher (U = 3.0 p =.003), with obese individuals reporting the highest non-work-related screen hours per week (Wald χ2= 8.9 p =.012). Inverse associations were found for mental well-being where higher lockdown scores of Kessler-10 (p =.011), Dass-21 anxiety (p =.027) and Dass-21 depression (p =.011) were associated with lower physical activity levels. A key qualitative message from participants was wanting to know how to stay healthy during lockdown. Conclusions: Lockdown was associated with lower physical activity, higher non-work-related screen time and more sitting time compared to post lockdown which also reported higher body mass index. Lower levels of mental well-being were associated with lower physical activity levels during lockdown. Given the known positive affect of physical activity on mental well-being and obesity, and the detrimental associations shown in this study, a key public health message should be considered in an attempt to maintain healthy activity behaviours in future lockdowns and similar emergency situations to promote and maintain positive well-being. Furthermore, consideration should be given to the isolation of a community due to infectious disease outbreaks and to recognise the important role physical activity plays in maintaining weight and supporting good mental health.

Greater Traditionalism Predicts Covid-19 Precautionary Behaviors Across 27 Societies, Theodore Samore, D. M. T. Fessler, A. M. Sparks, C. Holbrook, L. Aaroe, Norman P. Li, Kai Lin Lynn Tan, Et Al

Research Collection School of Social Sciences

People vary both in their embrace of their society’s traditions, and in their perception of hazards as salient and necessitating a response. Over evolutionary time, traditions have offered avenues for addressing hazards, plausibly resulting in linkages between orientations toward tradition and orientations toward danger. Emerging research documents connections between traditionalism and threat responsivity, including pathogen-avoidance motivations. Additionally, because hazard-mitigating behaviors can conflict with competing priorities, associations between traditionalism and pathogen avoidance may hinge on contextually contingent tradeoffs. The COVID-19 pandemic provides a real-world test of the posited relationship between traditionalism and hazard avoidance. Across 27 societies (N = 7844), we …

Public Service Motivation And Job Satisfaction Amid Covid-19: Exploring The Effects Of Work Environment Changes, Seulki Lee, Chongmin Na

Research Collection School of Social Sciences

The COVID-19 pandemic has brought critical changes to job demands and resources, which in turn affect employee motivation and outcomes. This study explores how COVID-19–induced work intensity and COVID-19–related organizational support influence public service motivation (PSM) and job satisfaction. Using survey data from a nationally representative sample of 1,430 South Korean central government employees collected during the pandemic (May–June 2020), we find that COVID-19–induced work intensity is positively associated with PSM, which in turn has a positive association with job satisfaction. We also find that COVID-19–related organizational support has both direct and indirect associations with job satisfaction through PSM. These …

Building Up A Genomic Surveillance Platform For Sars-Cov-2 In The Middle Of A Pandemic: A True North-South Collaboration, Waqasuddin Khan, Furqan Kabir, Samiah Kanwar, Fatima Aziz, Sahrish Muneer, Adil Kalam, Mehdia Ali, Nadia Ansari, Fyezah Jehan, Muhammad Imran Nisar

Department of Paediatrics and Child Health

Next-generation sequencing technology has revolutionised pathogen surveillance over the last two decades. However, the benefits are not equitably distributed, with developing countries lagging far behind in acquiring the required technology and analytical capacity. Recent declines in the cost associated with sequencing-equipment and running consumables have created an opportunity for broader adoption. During the COVID-19 pandemic, rapid diagnostics development and DNA sequencing revolutionised the ability to diagnose and sequence SARS-CoV-2 rapidly. Socioeconomic inequalities substantially impact the ability to sequence SARS-CoV-2 strains and undermine a developing country's pandemic preparedness. Low- and middle-income countries face additional challenges in establishing, maintaining and expanding genomic …

Outbreak Communication: Exploring The Relationships Between Health Information Seeking Behaviors, Vested Interests, And Covid-19 Knowledge In U.S. Midwest Populations, Alicia Mason, Josh Compton, Elizabeth Spencer, Kaitlin Barnett

Faculty Submissions

On February 15, 2020, the World Health Organization (WHO) Director, General Tedros Adhanom Ghebreyesus, stated at a Munich Security Conference, “We’re not just fighting an epidemic; we’re fighting an infodemic,” (Zarocostas, 2020, p. 676). The term ‘infodemic’ refers to the onslaught of both accurate and inaccurate health information surrounding the COVID-19 pandemic. The concept of an ‘infodemic’ was quickly integrated into mass media, popular culture (i.e., documentaries, podcasts), and eventually scholarly literature. In response to COVID-19, health communication scholars have centered on understanding specific messaging strategies such as the use of fear appeals (Stolow et al., 2020), nature of advertising …

Journal Articles

BACKGROUND: While vaccines have established utility against COVID-19, phase 3 efficacy studies have generally not comprehensively evaluated protection provided by previous infection or hybrid immunity (previous infection plus vaccination). Individual patient data from US government-supported harmonized vaccine trials provide an unprecedented sample population to address this issue. We characterized the protective efficacy of previous SARS-CoV-2 infection and hybrid immunity against COVID-19 early in the pandemic over three-to six-month follow-up and compared with vaccine-associated protection.

METHODS: In this post-hoc cross-protocol analysis of the Moderna, AstraZeneca, Janssen, and Novavax COVID-19 vaccine clinical trials, we allocated participants into four groups based on previous-infection …

The Public Health Impact Of Paxlovid Covid-19 Treatment In The United States, Yuan Bai, Zhanwei Du, Lin Wang, Eric H. Y. Lau, Isaac Fung, Petter Holme, Ben Cowling, Alison Galvani, Robert Krug, Lauren Ancel Meyers

Department of Biostatistics, Epidemiology, and Environmental Health Sciences Faculty Publications

The antiviral drug Paxlovid has been shown to rapidly reduce viral load. Coupled with vaccination, timely administration of safe and effective antivirals could provide a path towards managing COVID-19 without restrictive non-pharmaceutical measures. Here, we estimate the population-level impacts of expanding treatment with Paxlovid in the US using a multi-scale mathematical model of SARS-CoV-2 transmission that incorporates the within-host viral load dynamics of the Omicron variant. We find that, under a low transmission scenario (Re∼1.2) treating 20% of symptomatic cases would be life and cost saving, leading to an estimated 0.26 (95% CrI: 0.03, 0.59) million hospitalizations averted, 30.61 (95% …

The Impact Of Vaccinations And Chronic Disease On Covid Death Rates, James L. Doti

Economics Faculty Articles and Research

This study presents a theoretical and empirical regression model to measure the efficacy of vaccinations in reducing COVID death rates across states over the 3/10/21 to 12/28/22 period. During that period, it was estimated that the availability of vaccinations resulted in a reduction of 427,000 COVID deaths in the nation. To arrive at that estimate, other covariants were held constant. In particular, it was found that chronic disease should be included as an explanatory variable to arrive at unbiased measures of the efficacy of vaccinations in reducing deaths. In addition, the percentage of people over the age of 65 was …

Igg3 Subclass Antibodies Recognize Antigenically Drifted Influenza Viruses And Sars-Cov-2 Variants Through Efficient Bivalent Binding, Marcus J. Bolton, Jefferson J.S. Santos, Claudia P. Arevalo, Trevor Griesman, Megan Watson, Shuk Hang Li, Paul Bates, Holly Ramage, Patrick C. Wilson, Scott E. Hensley

Department of Microbiology and Immunology Faculty Papers

The constant domains of antibodies are important for effector functions, but less is known about how they can affect binding and neutralization of viruses. Here, we evaluated a panel of human influenza virus monoclonal antibodies (mAbs) expressed as IgG1, IgG2, or IgG3. We found that many influenza virus-specific mAbs have altered binding and neutralization capacity depending on the IgG subclass encoded and that these differences result from unique bivalency capacities of the subclasses. Importantly, subclass differences in antibody binding and neutralization were greatest when the affinity for the target antigen was reduced through antigenic mismatch. We found that antibodies expressed …

Covid-19 Mortality Rates Were Higher In States That Limited Governments From Enacting Public Health Emergency Orders, Xue Zhang, Mildred Warner, Gen Meredith

Center for Policy Research

State and local governments enacted various public health emergency policies during the COVID-19 pandemic that resulted in lower infection and death rates than would have occurred without these policies. However, some states limited emergency public health authority of state executives, state governors, and state and local officials during the pandemic. This brief summarizes the results of a study that used data from the Center for Public Health Law Research and Oxford COVID-19 Government Response Tracker to explore which states passed laws that limited emergency public health authority during the COVID-19 pandemic and the effects of those limitations on COVID-19 death …

Automated Lung Ultrasound Pulmonary Disease Quantification Using An Unsupervised Machine Learning Technique For Covid-19, Hersh Sagreiya, Michael A Jacobs, Alireza Akhbardeh

Journal Articles

COVID-19 is an ongoing global health pandemic. Although COVID-19 can be diagnosed with various tests such as PCR, these tests do not establish pulmonary disease burden. Whereas point-of-care lung ultrasound (POCUS) can directly assess the severity of characteristic pulmonary findings of COVID-19, the advantage of using US is that it is inexpensive, portable, and widely available for use in many clinical settings. For automated assessment of pulmonary findings, we have developed an unsupervised learning technique termed the calculated lung ultrasound (CLU) index. The CLU can quantify various types of lung findings, such as A or B lines, consolidations, and pleural …
