Purpose The goal of this study is to analyze the relationship between public governance and COVID-19 vaccinations during early 2021 assess preparedness countries timely policy responses cope with pandemic crises. Design/methodology/approach This global elaborates descriptive statistics, correlations, regression analyses Independent Samples T -Test on 112 countries, comparing those high/low level governance, determine whether statistical evidence supports hypothesis that good can improve administration vaccines. Findings Bivariate correlation reveals doses vaccines administered × 100 inhabitants have a high positive association General Index Governance ( r = 0.58, p -value <0.01). result confirmed by partial (controlling density population per km 2 ): 0.584, <0.001. coefficient in models also indicates an increase improves expected <0.001). Research limitations/implications Although has provided interesting results are, course, tentative, it several limitations. First, limitation lack data countries. Second, not all possible confounding factors affect vaccination against are investigated, such as country-specific health investments expenditures, these aspects should be examined future development research. A third limit related measurement through World Indicators, which based only perceptions biased different socio-economic factors. Practical implications identification determining may help design best practices for improving resilience face Social improvement foster rapid rollout threats negative effects their impact. Originality/value presents analysis role crises society.

Sources, diffusion and prediction in COVID-19 pandemic: lessons learned to face next health emergency

AIMS Public Health, Journal Year: 2023, Volume and Issue: 10(1), P. 145 - 168

Published: Jan. 1, 2023

<abstract> <p>Scholars and experts argue that future pandemics and/or epidemics are inevitable events, the problem is not whether they will occur, but when a new health emergency emerge. In this uncertain scenario, one of most important questions an accurate prevention, preparedness prediction for next pandemic. The main goal study twofold: first, clarification sources factors may trigger pandemic threats; second, examination models on-going pandemics, showing pros cons. Results, based on in-depth systematic review, show vital role environmental in spread Coronavirus Disease 2019 (COVID-19), many limitations epidemiologic because complex interactions between viral agent SARS-CoV-2, environment society have generated variants sub-variants with rapid transmission. insights here are, whenever possible, to clarify these aspects associated public order provide lessons learned policy reduce risks emergence diffusion having negative societal impact.</p> </abstract>

Environmental Science and Pollution Research, Journal Year: 2022, Volume and Issue: 30(1), P. 2020 - 2028

Abstract The goal of the study here is to analyze and assess whether strict containment policies cope with Coronavirus Disease 2019 (COVID-19) pandemic crisis are effective interventions reduce high numbers infections deaths. A homogenous sample 31 countries categorized in two sets: or low strictness public policy COVID-19 crisis. findings suggest that a intensity have average confirmed cases fatality rates related lower than (confirmed 24.69% vs. 26.06% 74.33% 76.38%, respectively, containment). What this adds levels restriction may not be useful measures control containing spread negative impact pandemics similar additionally generates substantial social economic costs. These can explained manifold socioeconomic environmental factors support transmission dynamics circulation pandemic. Hence, (and also share administering new vaccines) seem effectiveness stop driven by mutant viral agents. results design health for prevention preparedness future should underpinned good governance adoption technology, rather generalized polices having ambiguous effects society.

Coronavirus Disease 2019 (COVID-19) has caused tremendous losses to the world. This study addresses impact and diffusion of five major new coronavirus variants namely Alpha, Beta, Gamma, Eta, Delta lineage. The results this indicate that Africa Europe will be affected by most compared with other continents. comparative analysis indicates vaccination can contain spread virus in continent, non-pharmaceutical interventions (NPIs), such as restriction on gatherings close public transport, effectively curb pandemic, especially densely populated According our Global Prediction System COVID-19 Pandemic, delta lineage US shows seasonal oscillation characteristics, first wave occur October 2021, record 323,360, followed a small resurgence April 2022, 184,196, while second reach 232,622 cases 2022.

Abstract This study reveals that a vast vaccination campaign is necessary but not sufficient public policy to reduce the negative impact of Coronavirus Disease 2019 (COVID-19) pandemic crisis because manifold factors guide spread this new infectious disease and related mortality in society. Statistical evidence here, based on worldwide sample countries, shows positive correlation between people fully vaccinated COVID-19 ( r = + 0.65, p-value < 0.01). Multivariate regression, controlling income per capita, confirms finding. Results suggest increasing share against seems be health COVID-19. The findings here can explained with role Peltzman effect, variants, environmental socioeconomic affect diffusion extends knowledge research field design effective policies management for facing next threats.
