Background: Over the course of the COVID-19 pandemic, colleges and universities have focused on creating policies, such as mask mandates, to minimize COVID-19 transmission both on their campuses and in the surrounding community. Adherence to and opinions about these policies remain largely unknown.

Methods: The Centers for Disease Control and Prevention (CDC) developed a cross-sectional study, the Mask Adherence and Surveillance at Colleges and Universities Project (MASCUP!), to objectively and inconspicuously measure rates of mask use at institutes of higher education via direct observation.

Introduction: The COVID-19 pandemic posed many challenges for local health departments (LHDs). This study examines how stay-at-home orders impacted the provision of essential public health services and subsequent increased use of online health communication by LHDs for rural populations in Appalachian Kentucky during the first year of the COVID-19 pandemic.

Methods: A survey to gather information about provision of essential public health services was administered to five LHDs representing 13 counties between June 2020 and December 2020.

Article Synopsis
  • Limited data exists on SARS-CoV-2 infections in fully vaccinated college students and potential reinfections among student athletes, prompting a study by the CDC and NCAA.
  • Among 1378 student athletes who tested positive, 77.6% were unvaccinated, while 22.4% had breakthrough infections post-vaccination, with notable differences observed based on race.
  • The findings highlight ongoing risks of COVID-19 among vaccinated individuals and suggest a need for continued precautions and further research on health equity in young athletes.

Approximately 41% of adults aged 18-24 years in the United States are enrolled in a college or university (1). Wearing a face mask can reduce transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19) (2), and many colleges and universities mandate mask use in public locations and outdoors when within six feet of others. Studies based on self-report have described mask use ranging from 69.

Mass gatherings have been implicated in higher rates of transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), and many sporting events have been restricted or canceled to limit disease spread (1). Based on current CDC COVID-19 mitigation recommendations related to events and gatherings (2), Major League Baseball (MLB) developed new health and safety protocols before the July 24 start of the 2020 season. In addition, MLB made the decision that games would be played without spectators.

Background: Though commercial production of polychlorinated biphenyls was banned in the United States in 1977, exposure continues due to their environmental persistence. Several studies have examined the association between environmental polychlorinated biphenyl exposure and modulations of the secondary sex ratio, with conflicting results.

Objective: Our objective was to evaluate the association between maternal preconceptional occupational polychlorinated biphenyl exposure and the secondary sex ratio.

Objectives: We investigated the relation between respiratory symptoms and exposure to water-damaged homes and the effect of respirator use in posthurricane New Orleans, Louisiana.

Methods: We randomly selected 600 residential sites and then interviewed 1 adult per site. We created an exposure variable, calculated upper respiratory symptom (URS) and lower respiratory symptom (LRS) scores, and defined exacerbation categories by the effect on symptoms of being inside water-damaged homes.

Objectives: The specific objective of this study was to conduct a dose response experiment with Mycoplasma pulmonis in Sprague-Dawley rats to develop a reproducible animal model of maternal and fetal infection that would provide a versatile mechanism to address the innate fetal immune response during intrauterine infection.

Study Design: Pregnant rats were infected intravenously at gestation day 14 with 0 (control), 10(1), 10(3), 10(5), and 10(7) colony forming units of M. pulmonis and necropsied at gestational day 18.

To assess knowledge, attitudes, and practices related to mold exposure in postflood New Orleans, the authors surveyed 159 residents and 76 remediation workers, using logistic regression to explore associations. Nearly all answered "yes" to the questionnaire item, "Do you think mold can make people sick?" and most knew respirators were recommended for cleaning mold. Residents (87%) and workers (47%) said they believed that television or radio were the best ways to communicate information about mold.

We evaluated correctness of N95 filtering facepiece respirator donning by the public in post-hurricane New Orleans, where respirators were recommended for mold remediation. We randomly selected, interviewed, and observed 538 participants, using multiple logistic regression for analysis. Only 129 (24%) participants demonstrated proper donning.

In August and September 2005, Hurricanes Katrina and Rita caused breeches in the New Orleans, LA, levee system, resulting in catastrophic flooding. The city remained flooded for several weeks, leading to extraordinary mold growth in homes. To characterize the potential risks of mold exposures, we measured airborne molds and markers of molds and bacteria in New Orleans area homes.
