ABSTRACT

School closures due to the COVID-19 pandemic have affected teachers and changed their role significantly. This chapter explores the extent to which early childhood education (ECE) teachers were engaged in children’s early learning during school closure through communication with their parents and families in three countries: Ethiopia, Liberia, and Pakistan. Using mobile phone surveys and key informant interviews, we investigate the support pre-primary teachers received during school closures and how they were able to support children’s home-based learning and prepare for school reopening. In all three countries, many teachers were in contact with children and families during school closures, yet the percentage varies by country, from 33% in Ethiopia to 64% in Liberia and 100% in Pakistan. Teachers in Ethiopia and Pakistan reported that children from disadvantaged backgrounds were missing out on essential support, but about 70% of ECE teachers sought to accommodate their learning needs or support psychosocial well-being. We discuss policy implications to support ECE teachers and children in the current and future crises in order to improve responsiveness and resilience in ECE systems. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

BACKGROUND: Biomarkers have been widely explored for coronavirus disease 2019 diagnosis. Both viral RNA or antigens (Ag) in the respiratory system and antibodies (Ab) in blood are used to identify active infection, transmission risk, and immune response but have limitations. This study investigated the diagnostic utility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid protein (N-Ag) in serum. METHODS: We retrospectively studied 208 randomly selected cases with SARS-CoV-2 infection confirmed by viral RNA test in swabs. N-Ag concentrations were measured in remnant serum samples, compared to viral RNA or Ab results, and correlated to electronic health records for clinical value evaluation. RESULTS: Serum N-Ag was detected during active infection as early as day 2 from symptom onset with a diagnostic sensitivity of 81.5%. Within 1 week of symptom onset, the diagnostic sensitivity and specificity reached 90.9% (95% CI, 85.1%-94.6%) and 98.3% (95% CI, 91.1%-99.9%), respectively. Moreover, serum N-Ag concentration closely correlated to disease severity, reflected by highest level of care, medical interventions, chest imaging, and the length of hospital stays. Longitudinal analysis revealed the simultaneous increase of Abs and decline of N-Ag. CONCLUSIONS: Serum N-Ag is a biomarker for SARS-CoV-2 acute infection with high diagnostic sensitivity and specificity compared to viral RNA in the respiratory system. There is a correlation between serum N-Ag concentrations and disease severity and an inverse relationship of N-Ag and Abs. The diagnostic value of serum N-Ag, as well as technical and practical advantages it could offer, may meet unsatisfied diagnostic and prognostic needs during the pandemic.

ABSTRACT

The world is currently in a pandemic of COVID-19 (Coronavirus disease-2019) caused by a novel positive-sense, single-stranded RNA ß-coronavirus referred to as SARS-CoV-2. Here we investigated rates of SARS-CoV-2 infection in the greater Cincinnati, Ohio, USA metropolitan area from August 13 to December 8, 2020, just prior to initiation of the national vaccination program. Examination of 9,550 adult blood donor volunteers for serum IgG antibody positivity against the SARS-CoV-2 Spike protein showed an overall prevalence of 8.40%, measured as 7.56% in the first 58 days and 9.24% in the last 58 days, and 12.86% in December 2020, which we extrapolated to ~20% as of March, 2021. Males and females showed similar rates of past infection, and rates among Hispanic or Latinos, African Americans and Whites were also investigated. Donors under 30 years of age had the highest rates of past infection, while those over 60 had the lowest. Geographic analysis showed higher rates of infectivity on the West side of Cincinnati compared with the East side (split by I-75) and the lowest rates in the adjoining region of Kentucky (across the Ohio river). These results in regional seroprevalence will help inform efforts to best achieve herd immunity in conjunction with the national vaccination campaign.

ABSTRACT

This paper explores how trust in formal information sources (government and media) and informal information sources (interpersonal) about COVID-19 influences compliance with preventive measures. This cross-sectional study uses convenience sampling of 478 adult participants. Data analyses using structural equation modeling with multigroup comparisons examine hypothesized relationships between trust in information sources and preventative behaviors and social distancing. Results suggest that understanding of COVID-19 causes is related to trust in formal information sources, but not to trust in informal information. Self-efficacy for prevention is related to trust in informal information sources, but not to trust in formal information sources. Worry about contracting COVID-19 is related to trust in formal information sources, but not to informal ones. Engaging in preventive measures is linked to both self-efficacy for prevention and worry, while social distancing was related only to worry. These findings have important implications for public health policy guidelines centered on clear and truthful media messages. The findings also facilitate comparative analyses of reactions to information sources across a decade of evolving attitudes toward media and government, between two cultures (Hong Kong vs. the USA), and between two different global pandemics.

ABSTRACT

As COVID-19 has become a global pandemic, health researchers and practitioners have focused attention on identifying the factors that may help to shape health-protective behaviors, protecting individual health and well-being, and helping to mitigate the spread of COVID-19. This study explores the potential role of self-leadership and psychological capital (PsyCap) as key cognitive resources for shaping health-protective behaviors. Using multiple theoretical frameworks (social cognitive theory, psychological resources theory, and the health belief model), this paper develops and tests a hypothesized serial mediation model in which PsyCap and coping self-efficacy mediate the relationship between self-leadership and health-protective behaviors including hand washing, wearing face masks, and social distancing. Results suggest that PsyCap and coping self-efficacy mediate the positive relationship between self-leadership and health-protective behaviors. These results yield valuable insights regarding the usefulness of self-leadership and PsyCap as cognitive resources for shaping health-protective behaviors and for possible self-leadership and PsyCap interventions, potentially tailored to at-risk populations, which should have practical benefits for both the current and future pandemics and health crises.

ABSTRACT

The world is currently in a pandemic of COVID-19 (Coronavirus disease-2019) caused by a novel positive-sense, single-stranded RNA {beta}-coronavirus referred to as SARS-CoV-2. Fortunately, most infected individuals recover and are then resistant to re-infection for a period, indicating that a vaccination approach can be successful. Elucidation of rates of past SARS-CoV-2 infection within select regions across the United States of America (USA) will help direct vaccination efforts and together will inform our approach towards achieving herd immunity. Here we investigated rates of SARS-CoV-2 infection in the greater Cincinnati, Ohio, USA metropolitan area from August to December 2020, just prior to initiation of the national vaccination program. Examination of 9,550 adult blood donor volunteers for serum IgG antibody positivity against the SARS-CoV-2 Spike protein showed an overall prevalence of 8.40%, measured as 7.56% in the first 58 days of this time frame, versus a significant increase to 9.24% in the last 58 days, and a final rate of 12.86% in December 2020. Approximately 56% of Spike seropositive individuals also had immunoreactivity against the receptor binding domain (RBD) within the Spike protein, which is associated with viral neutralization. Males and females in the Cincinnati area showed nearly identical rates of past infection, and rates among Hispanics, African Americans and Caucasians were not significantly different. Interestingly, donors under 30 years of age had the highest rates of past infection, while those over 60 had the lowest. Geographic analysis showed that the West side of Cincinnati had a rate of 9.63% versus 8.13% on the East side (demarcated by Interstate-75), while the adjoining area of Kentucky was 7.04% (as demarcated by the Ohio River). These results among healthy blood donors will be critical in calculating the time needed to achieve regional herd immunity in conjunction with the national vaccination campaign.
