Bridging Language Barriers in COVID-19 Research: Descriptive Study of AccesoCovid.com's Reach and User Engagement.

Background: The COVID-19 pandemic underscored the challenge of swiftly disseminating research findings to a global audience. Language barriers further exacerbated disparities in access to timely scientific information, particularly for non-English speaking communities. The majority of COVID-19 research was published in English, limiting accessibility for Spanish-speaking populations.

Rapid and sustained contact tracing training for COVID-19 in San Francisco: a training model for developing an emergency public health workforce.

The City and County of San Francisco was the first municipality in the United States to institute a COVID-19 contact tracing program. The San Francisco Department of Public Health (SFDPH) and the University of California, San Francisco (UCSF) created an outcome-based fully remote contact tracing curriculum using participatory learning methods to train non-public health emergency workers as contact tracers. Between April and December 2020, we trained over 300 individuals in contact tracing skills and procedures over three training phases.

Assessing the impact of one million COVID-19 deaths in America: economic and life expectancy losses.

Between February 2020 and May 2022, one million Americans have died of COVID-19. To determine the contribution of those deaths to all-cause mortality in terms of life expectancy reductions and the resulting economic welfare losses, we calculated their combined impact on national income growth and the added value of lives lost. We estimated that US life expectancy at birth dropped by 3.

"I Have to Ask": A Mixed-Methods Study on the Collection of Sexual Orientation and Gender Identity Data Within the San Francisco County COVID-19 Case Investigation and Contact Tracing Program.

Objective: To understand how the San Francisco (SF) COVID-19 case investigation and contact tracing (CICT) workforce documented sexual orientation and gender identity (SOGI) data, as well as a qualitative assessment of the workforce's capacity to successfully collect that data.

Methods: This mixed-methods project analyzed data from 2 sources: SOGI item completeness among adult completed/partially completed interviews in the SF digital CICT COVID-19 database, and a secondary data analysis of qualitative data from 16 semistructured 90-minute virtual interviews with the SF CICT workforce, between November 14, 2020, and April 14, 2021.

Results: Among 15 416 COVID-19 cases and 7836 close contacts, sexual orientation data are missing from 20% of cases and 17% of contacts.

Real World Feedback: How Well Did the Virtual Training Academy Prepare California's COVID-19 Contact Tracing Workforce?

To effectively respond to the COVID-19 pandemic, California had to quickly mobilize a substantial number of case investigators (CIs) and contact tracers (CTs). This workforce was comprised primarily of redirected civil servants with diverse educational and professional backgrounds. The purpose of this evaluation was to understand whether the weeklong, remote course developed to train California's CI/CT workforce (i.

Outdoor Activities Associated with Lower Odds of SARS-CoV-2 Acquisition: A Case-Control Study.

Access to recreational physical activities, particularly in outdoor spaces, has been a crucial outlet for physical and mental health during the COVID-19 pandemic. There is a need to understand how conducting these activities modulates the risk of SARS-CoV-2 infection. In this case-control study of unvaccinated individuals conducted in San Francisco, California, the odds of testing positive to SARS-CoV-2 were lower for those who conducted physical activity in outdoor locations (adjusted odds ratio [aOR]: 0.

Evaluating the Impact of Language Concordance on Coronavirus Disease 2019 Contact Tracing Outcomes Among Spanish-Speaking Adults in San Francisco Between June and November 2020.

We evaluated the impact of language concordance-clinician or public health worker fluency in a patient's primary language-on coronavirus disease 2019 (COVID-19) contact tracing outcomes among 2668 Spanish-speaking adults in San Francisco. Language concordance was associated with 20% greater odds of COVID-19 testing and 53% greater odds of support service referrals.

Establishment and Evaluation of a Large Contact-Tracing and Case Investigation Virtual Training Academy.

During the COVID-19 pandemic, the Virtual Training Academy (VTA) was established to rapidly develop a contact-tracing workforce for California. Through June 2021, more than 10 000 trainees enrolled in a contact-tracing or case investigation course at the VTA. To evaluate program effectiveness, we analyzed trainee pre- and postassessment results using the Wilcoxon signed-rank test.

COVID-19 and global equity for health: The good, the bad, and the wicked.

Elvin Geng and co-authors discuss monitoring and achieving equity in provision of vaccines for COVID-19.

A National Public Health Workforce to Control COVID-19 and Address Health Disparities in the United States.

A large, well-trained public health workforce is needed to control coronavirus disease 2019 (COVID-19) in the United States in the short term and to address other disease burdens and health disparities in the long run. As the public health workforce declined following the 2008 financial crisis, many US jurisdictions struggled to hire a sufficient number of staff for roles initially including testing and contact tracing and more recently for vaccination. Ultimately, COVID-19 control will require a combination of vaccination and rapid investigation, contact tracing, and quarantine to stop chains of transmission.

Contact Tracing and the COVID-19 Response in Africa: Best Practices, Key Challenges, and Lessons Learned from Nigeria, Rwanda, South Africa, and Uganda.

Most African countries have recorded relatively lower COVID-19 burdens than Western countries. This has been attributed to early and strong political commitment and robust implementation of public health measures, such as nationwide lockdowns, travel restrictions, face mask wearing, testing, contact tracing, and isolation, along with community education and engagement. Other factors include the younger population age strata and hypothesized but yet-to-be confirmed partially protective cross-immunity from parasitic diseases and/or other circulating coronaviruses.

Identifying research priorities for health professions education research in sub-Saharan Africa using a modified Delphi method.

Background: Recent increases in health professions education (HPE) research in sub-Saharan Africa (SSA), though substantial, have predominantly originated from single institutions and remained uncoordinated. A shared research agenda can guide the implementation of HPE practices to ultimately influence the recruitment and retention of the health workforce. Thus, the authors aimed to generate and prioritise a list of research topics for HPE research (HPER) in SSA.

Outcomes of Contact Tracing in San Francisco, California-Test and Trace During Shelter-in-Place.

This case series evaluates case investigation and contact tracing outcomes in San Francisco, California, during shelter-in-place restrictions during the COVID-19 pandemic.

Improving quality is necessary to building a TB-free world: Lancet Commission on Tuberculosis.

The Lancet Commission on Tuberculosis (TB) set out to establish a roadmap for how high burden countries could get on track to meet the goals established by the UN High Level Meeting (UNHLM) in September 2018. The report sought to answer the question It provides a comprehensive analysis and specific recommendations to address this question and, ultimately, remove the barriers to building a TB-free World. Notably, the report highlights the importance of improving the quality of care as an essential component of ending the epidemic.

Improving the cascade of global tuberculosis care: moving from the "what" to the "how" of quality improvement.

Tuberculosis is preventable, treatable, and curable, yet it has the highest mortality rate of infectious diseases worldwide. Over the past decade, services to prevent, screen, diagnose, and treat tuberculosis have been developed and scaled up globally, but progress to end the disease as a public health threat has been slow, particularly in low-income and middle-income countries. In these settings, low-quality tuberculosis prevention, diagnostic, and treatment services frustrate efforts to translate use of existing tools, approaches, and treatment regimens into improved individual and public health outcomes.
