The Graph is one of the largest Open Access collections of metadata records and links between publications, datasets, software, projects, funders, and organizations, aggregating 12,000+ scientific data sources world-wide, among which the Covid-19 data sources Zenodo COVID-19 Community, WHO (World Health Organization), BIP! FInder for COVID-19, Protein Data Bank, Dimensions, scienceOpen, and RSNA. The dump consists of a tar archive containing gzip files with one json per line. Each json is compliant to the schema available at https://doi.org/10.5281/zenodo.7492313.

The present research conducts a formal analysis of the interactive decisions concerning the enterprise of COVID-19 vaccination on the part of governments and citizens. It specifically constructs a non-cooperative static game with complete information between the citizen and the government encompassing the strategies of vaccination and no vaccination with regard to the former and the strategies of direct imposition, subsistence restrictions, luxury restrictions and no imposition with regard to the latter. On account of its payoff structure the present analysis finds that the game in question presents one sole and strict pure strategy Nash equilibrium, being that of strategies no vaccination and no imposition, respectively. The core rationale is that the citizen accepts COVID-19 vaccination only if his survival is placed at risk, because of the inherent unlawfulness presented by COVID-19 vaccination, itself due to foetal exploitation and potentially adverse effects, thereby prompting the government not to impose it, lest individual integrity and societal rights be violated as well. It furthermore shows that the exogenous elimination of the no imposition strategy on the part of the government transforms the Nash equilibrium into that of strategies vaccination and direct imposition, respectively, as materially come to pass. It finally determines that the unlikely addition of the revolution strategy on the part of the citizen in the presence of the elimination of the no imposition strategy on the part of the government likewise admits one sole and strict pure strategy Nash equilibrium, either in strategies vaccination and direct imposition or in strategies revolution and direct imposition, respectively.

Dress code is standard in the Australian public sector, with smart business casual the norm. However, over the last two years, as many workers relocated to the home office, bedroom or kitchen table during the COVID-19 pandemic , work attire has taken on new meaning. A key but under-researched advantage of remote working has been the relaxing in many professions dress codes, with ‘COVID casual’ becoming the norm for many workers. This report highlights the role of dress codes, appearance, and aesthetics in the Australian public sector and the refashioning of professional attire in the age of remote work.

Considerable concerns relating to the duration of protective immunity against severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) exist, with evidence of antibody titers declining rapidly after infection and reports of reinfection. Here, we monitor the antibody responses against SARS-CoV-2 receptor-binding domain (RBD) for up to 6 months after infection. While antibody titers are maintained, _13% of the cohort's neutralizing responses return to background. However, encouragingly, in a selected subset of 13 participants, 12 have detectable RBD-specific memory B cells and these generally are increasing out to 6 months. Furthermore, we are able to generate monoclonal antibodies with SARS-CoV-2 neutralizing capacity from these memory B cells. Overall, our study suggests that the loss of neutralizing antibodies in plasma may be countered by the maintenance of neutralizing capacity in the memory B cell repertoire.

ackground: COVID-19 has heterogeneous manifestations, though one of the most common symptoms is a sudden loss of smell (anosmia or hyposmia). We investigated whether olfactory loss is a reliable predictor of COVID-19. Methods: This preregistered, cross-sectional study used a crowdsourced questionnaire in 23 languages to assess symptoms in individuals self-reporting recent respiratory illness. We quantified changes in chemosensory abilities during the course of the respiratory illness using 0-100 visual analog scales (VAS) for participants reporting a positive (C19+; n=4148) or negative (C19-; n=546) COVID-19 laboratory test outcome. Logistic regression models identified singular and cumulative predictors of COVID-19 status and post-COVID-19 olfactory recovery. Results: Both C19+ and C19- groups exhibited smell loss, but it was significantly larger in C19+ participants (mean±SD, C19+: -82.5±27.2 points; C19-: -59.8±37.7). Smell loss during illness was the best predictor of COVID-19 in both single and cumulative feature models (ROC AUC=0.72), with additional features providing no significant model improvement. VAS ratings of smell loss were more predictive than binary chemosensory yes/no-questions or other cardinal symptoms, such as fever or cough. Olfactory recovery within 40 days was reported for ~50% of participants and was best predicted by time since illness onset. Conclusions: As smell loss is the best predictor of COVID-19, we developed the ODoR-19 tool, a 0-10 scale to screen for recent olfactory loss. Numeric ratings <2 indicate high odds of symptomatic COVID-19 (10

Abstract The issue of coronavirus outbreak in the world, though new, is equally pervasive. It has posed a new and ambiguous challenge to the economic growth of countries around the world. Undoubtedly, the efforts of countries to curb the spread of this virus and reduce the number of deaths are necessary for other strategies that will be taken in other areas, especially in the economic field. Comparing countries only based on the statistics on virus spread and mortality without considering the contextual variables, can be misleading. Thus using dynamic data envelopment analysis, this study calculated the performance of 19 selected countries in two dimensions: inefficiency of preventing coronavirus spread and inefficiency of preventing deaths caused by a coronavirus from February 2 to April 12. According to the study, the inefficiency trend of preventing coronavirus spread in Singapore, South Korea, China, and Australia are decreasing during the period under review and the inefficiency trend of other countries, which of course differ in terms of inefficiency, are increasing with different slopes. Also, Australia, Finland, Japan, Malaysia, Singapore, and Thailand have experienced less inefficiency in preventing deaths caused by coronavirus compared to other countries. Stringency index and global health security (GHS) index have been used as well, to analyze the findings and in the end some suggestions have been presented.

O artigo apresenta um estudo a mercê das exportações brasileiras durante a pandemia do COVID-19. A forma mais eficiente que o governo encontrou para conter a contaminação e o número de mortes é o lockdown, que foi estabelecido no país. Entretanto, ocasionou fortes impactos na oferta e demanda de bens e produtos. A partir da paralisação do serviço industrial, induziu uma diminuição das manufaturas, e consequentemente, o seu consumo e suas exportações. O setor agropecuário cresceu nesse período, exportando cada vez mais produtos, atendendo a demanda por alimentos de vários países, mas a demanda interna ficou prejudicada, produzindo uma alta na maioria dos bens alimentícios. Um dos setores mais importante é o de serviços, que representa cerca de mais 70% no Produto Interno Bruto – PIB na qual caiu significativamente durante os dois primeiros trimestres do ano, somente no terceiro trimestre o PIB se valorizou frente ao período anterior. As expectativas para 2021, são de melhores resultados, a esperança é para que a vacina chegue no primeiro semestre e assim, aumente o consumo e encaminhando uma repercussão positiva para a economia brasileira, que tanto foi prejudicada.

Close proximity interactions facilitate the spread of COVID-19, which is predominantly transmitted via droplets. In this paper we study to what extend the transmission and mortality of the virus are related to social habits regarding physical interactions. Using regional data for a maximum of 8 European countries we find that a standard deviation increase in the percentage of people having daily face-to-face contacts raises COVID-19 cases by 10% but does not affect the number of fatalities. Analyzing the effects by type of contact, we observe that only the interactions with friends are relevant for the transmission and mortality of the virus. Additionally, our results show that this impact is reinforced by the presence of inter-generational families in the region. Finally, we find evidence of a negative relationship between civic habits and the growth rate of contagion between April and June 2020.
