Coping with the Challenges of COVID-19 Using the Sociotype Framework: A Rehearsal for the Next Pandemic

Impact of vaccination and non-pharmacological interventions on COVID-19: a review of simulation modeling studies in Asia

Introduction

Epidemiological modeling is widely used to offer insights into the COVID-19 pandemic situation in Asia. We reviewed published computational (mathematical/simulation) models conducted in Asia that assessed impacts of pharmacological and non-pharmacological interventions against COVID-19 and their implications for vaccination strategy.

Methods

A search of the PubMed database for peer-reviewed, published, and accessible articles in English was performed up to November 2022 to capture studies in Asian populations based on computational modeling of outcomes in the COVID-19 pandemic. Extracted data included model type (mechanistic compartmental/agent-based, statistical, both), intervention type (pharmacological, non-pharmacological), and procedures for parameterizing age. Findings are summarized with descriptive statistics and discussed in terms of the evolving COVID-19 situation.

Results

The literature search identified 378 results, of which 59 met criteria for data extraction. China, Japan, and South Korea accounted for approximately half of studies, with fewer from South and South-East Asia. Mechanistic models were most common, either compartmental (61.0%), agent-based (1.7%), or combination (18.6%) models. Statistical modeling was applied less frequently (11.9%). Pharmacological interventions were examined in 59.3% of studies, and most considered vaccination, except one study of an antiviral treatment. Non-pharmacological interventions were also considered in 84.7% of studies. Infection, hospitalization, and mortality were outcomes in 91.5%, 30.5%, and 30.5% of studies, respectively. Approximately a third of studies accounted for age, including 10 that also examined mortality. Four of these studies emphasized benefits in terms of mortality from prioritizing older adults for vaccination under conditions of a limited supply; however, one study noted potential benefits to infection rates from early vaccination of younger adults. Few studies (5.1%) considered the impact of vaccination among children.

Conclusion

Early in the COVID-19 pandemic, non-pharmacological interventions helped to mitigate the health burden of COVID-19; however, modeling indicates that high population coverage of effective vaccines will complement and reduce reliance on such interventions. Thus, increasing and maintaining immunity levels in populations through regular booster shots, particularly among at-risk and vulnerable groups, including older adults, might help to protect public health. Future modeling efforts should consider new vaccines and alternative therapies alongside an evolving virus in populations with varied vaccination histories.

COVID-19 and democracy: a scoping review

BACKGROUND

The resilience of democracy is tested under exogenous shocks such as crises. The COVID-19 pandemic has recently tested the resilience of democratic institutions and practices around the world.

AIM

The purpose of this article is to scope the early research literature that discusses democracy and the COVID-19 pandemic. We review scientific journal articles published during the first two years of the pandemic. We ask three research questions in scoping this body of literature: (1) what are the key topic areas of all published research that associates itself with both democracy and COVID-19, (2) what kinds of conceptual and theoretical contributions has research literature that more specifically discusses democracy under the pandemic produced, and (3) what are the impacts of democracy to the pandemic and vice versa according to empirical research?

METHODS

The scoping review methodology draws on systematic literature search strategies, computational methods, and manual coding. The systematic Web of Science search produced 586 articles for which we conducted a Correlated Topic Model. After technical and manual screening, we identified 94 journal articles that were manually coded.

RESULTS

The early research on democracy and the COVID-19 pandemic offers a versatile body of scholarship. The topic modeling shows that the scholarship discusses issues of crises, governance, rights, society, epidemiology, politics, electorate, technology, and media. The body of papers with conceptual and theoretical contributions has offered new insights on the difficulties, possibilities, and means to maintain democracy under a pandemic. Empirical research on democracy's impact on the COVID-19 pandemic and vice versa varies in terms of methodology, geographical scope, and scientific contributions according to the direction of influence studied. Democracy appears to have a significant impact on some aspects of policy responses and epidemiological characteristics of the pandemic. In most parts of the world, the scope, franchise, and authenticity of democracy narrowed down due to the pandemic, albeit in most cases only temporarily.

CONCLUSIONS

A significant number of papers show that the pandemic has accentuated democratic backsliding but is unlikely to have undermined established democracies that have proved resilient in face of the pandemic. But empirical research has also made visible some weak signals of antidemocratic tendencies that may become more accentuated in the longer run.

Newspaper coverage on solidarity and personal responsibility in the COVID-19 pandemic: A content analysis from Germany and German-speaking Switzerland

Solidarity and personal responsibility have been repeatedly called upon during the COVID-19 pandemic. This study quantifies and contextualizes the use of these terms in newspaper coverage in Germany and German-speaking Switzerland based on n = 640 articles from six functionally equivalent newspapers. The term solidarity in the context of the COVID-19 pandemic was mentioned in 541/640 articles (84.5%) and was primarily used during phases with high death rates and comparatively stringent policies in place, supporting the idea that solidarity was used to explain restrictive measures to the population and motivate people to comply with these measures. German newspapers published more articles on solidarity than Swiss-German newspapers, consistent with more stringent COVID-19 policies in Germany. Personal responsibility was mentioned in 133/640 articles (20.8%), meaning that the term was less frequently discussed than solidarity. Articles covering personal responsibility included more negative evaluations during phases of high infection rates as compared to phases of low infection rates. Findings indicate that the two terms were, at least to some extent, used in newspaper reporting to contextualize and justify COVID-19 policy during phases of high infection rates. Moreover, the term solidarity was used in a high variety of different contexts and the inherent limits of solidarity were rarely mentioned. Policymakers and journalists need to take this into account for future crises to not jeopardize the positive effects of solidarity.

Lessons Learned from the Lessons Learned in Public Health during the First Years of COVID-19 Pandemic

(1) Objectives: to investigate the main lessons learned from the public health (PH) response to COVID-19, using the global perspective endorsed by the WHO pillars, and understand what countries have learned from their practical actions. (2) Methods: we searched for articles in PubMed and CINAHL from 1 January 2020 to 31 January 2022. 455 articles were included. Inclusion criteria were PH themes and lessons learned from the COVID-19 pandemic. One hundred and forty-four articles were finally included in a detailed scoping review. (3) Findings: 78 lessons learned were available, cited 928 times in the 144 articles. Our review highlighted 5 main lessons learned among the WHO regions: need for continuous coordination between PH institutions and organisations (1); importance of assessment and evaluation of risk factors for the diffusion of COVID-19, identifying vulnerable populations (2); establishment of evaluation systems to assess the impact of planned PH measures (3); extensive application of digital technologies, telecommunications and electronic health records (4); need for periodic scientific reviews to provide regular updates on the most effective PH management strategies (5). (4) Conclusion: lessons found in this review could be essential for the future, providing recommendations for an increasingly flexible, fast and efficient PH response to a healthcare emergency such as the COVID-19 pandemic.

Food Security and Nutrition as the Neglected Missing Links in Cultural Evolution: The Role of the Sociotype

Food security and nutrition were major drivers of cultural evolution by enabling sociotypic development and communal living after the Neolithic agricultural revolution some 12,000 years ago. The sociotype unites concepts from the sciences and the humanities; in concert with the genotype it determines an individual's phenotype (observable traits and behavior), and together they advance societal culture. As such, the sociotype relates to an individual's dynamic interactions with the surrounding social environment throughout life and comprises three domains: the Individual, Relationships, and Context. Nutrition affects each domain, respectively, by ensuring the following dimensions of food security: utilization (metabolic fuel and health); accessibility (physical and economic); and availability (the right to nutritious food for all citizens). The sociotype is influenced by multiple factors, including diet-gene interactions, allostasis, microbiota, oxytocin, and culturally through mate selection, family bonds, social communication, political ideologies, and values. Food security, sociotypes, and culture form a complex adaptive system to enable coping with the circumstances of life in health and disease, to achieve sustainable development, and to eradicate hunger. The current geopolitical unrest highlights the absolutely critical role of this system for global security, yet many challenges remain in implementing this paradigm for society. Therefore, sustainable food security must be considered a fundamental human right and responsibility for safeguarding the survival and progress of the sociotypes of humankind (Homo culturus) worldwide.

Child food insecurity in the wake of the COVID-19 pandemic: urgent need for policy evaluation and reform in Israel's school feeding programs

Even in high-income countries like Israel, children have been particularly vulnerable to the surge in food insecurity driven by quarantines, unemployment, and economic hardships of the COVID-19 pandemic. Under normal circumstances, School Feeding Programs (SFPs) can help to ensure child food security. In the wake of the pandemic, policy makers worldwide have been challenged to adapt national SFPs to provide nutritional support to children (and indirectly to their families) during extended school closures. Most national SFPs implemented contingency plans to ensure continued nutritional support for children. In Israel, where SFPs were largely suspended during long periods of mandated school closing, there was a loss of 30–50% of feeding days for the ~ 454,000 children enrolled in the program. The lack of emergency contingency planning and failure to maintain Israeli SFPs during school closures reveals longstanding structural policy flaws that hindered coordination between relevant ministries and authorities and impeded the mobilization of funds and existing programs to meet the emergent need. The school feeding law does not identify child food security as an explicit aim, there are no benchmarks for monitoring and evaluating the program to ensure that the food aid reaches the children most in need, even routinely, and the Ministry of Education had no obligation to maintain the program and to marshal data on the participants that could be acted upon in the emergency. Moreover, because Israeli SFPs are “selective”, in other words, implemented according to community risk (low-income, high poverty rate) and geographical factors, attendant stigma and financial burdens can make participation in the program less attractive to families and communities that need them the most. We argue that Israel should make urgent, long-term improvements to the SFPs as follows: First, eliminating childhood food insecurity should be made an explicit goal of legislation in the broader context of national social, health, and nutritional goals, and this includes ensuring SFPs are maintained during emergencies. Second, the government should assume responsibility for the routine assessment and data collection on food insecurity among Israeli children. Third, SFPs should be subjected to rigorous independent program evaluation. Finally, a “universal” SFP providing nutritious diets would likely improve the health of all Israeli children, across all socioeconomic backgrounds. These steps to guarantee that Israeli children have food to realize their full physical and cognitive potential would emphasize Israel’s firm commitment to support multiple dimensions of health, educational achievement, and societal values, to combat the complex and long-term consequences of the pandemic, and to prepare for the next one.

RT-PCR Screening Tests for SARS-CoV-2 with Saliva Samples in Asymptomatic People: Strategy to Maintain Social and Economic Activities while Reducing the Risk of Spreading the Virus

The year 2020 will be remembered for the coronavirus disease 2019 (COVID-19) pandemic, which continues to affect the whole world. Early and accurate identification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is fundamental to combat the disease. Among the current diagnostic tests, real-time reverse transcriptase-polymerase chain reaction (RT-qPCR) is the most reliable and frequently used method. Herein, we discuss the interpretation of RT-qPCR results relative to viral infectivity. Although nasopharyngeal swab samples are often used for RT-qPCR testing, they require collection by trained medical staff. Saliva samples are emerging as an inexpensive and efficient alternative for large-scale screening. Pooled-sample testing of saliva has been applied for mass screening of SARS-CoV-2 infection. Current policies recommend isolating people with borderline cycle threshold (Ct) values (35<Ct <40), despite these Ct values indicating minimal infection risk. We propose the new concept of a "social cut-off" Ct value and risk stratification based on the correlation of Ct with infectivity. We also describe the experience of RT-qPCR screening of saliva samples at our institution. It is important to implement a scientific approach to minimize viral transmission while allowing economic and social activities to continue.
