<li><strong>Model design for non-parametric phylodynamic inference and applications to pathogen surveillance</strong> -
|

<div>
|

Inference of effective population size from genomic data can provide unique information about demographic history, and when applied to pathogen genetic data can also provide insights into epidemiological dynamics. The combination of non-parametric models for population dynamics with molecular clock models which relate genetic data to time has enabled phylodynamic inference based on large sets of time-stamped genetic sequence data. The methodology for non-parametric inference of effective population size is well-developed in the Bayesian setting, but here we develop a frequentist approach based on non-parametric latent process models of population size dynamics. We appeal to statistical principles based on out-of-sample prediction accuracy in order to optimize parameters that control shape and smoothness of the population size over time. We demonstrate the flexibility and speed of this approach in a series of simulation experiments, and apply the methodology to reconstruct the previously described waves in the seventh pandemic of cholera. We also estimate the impact of non-pharmaceutical interventions for COVID-19 in England using thousands of SARS-CoV-2 sequences. By incorporating a measure of the strength of these interventions over time within the phylodynamic model, we estimate the impact of the first national lockdown in the UK on the epidemic reproduction number.

<li><strong>L’enfer c’est les autres? The effects of COVID-19 virus on interpersonal trust</strong> -

Does the COVID-19 pandemic affect interpersonal trust? Most evidence shows that natural disasters reinforce trust and cooperation, but the COVID-19 virus differs from other calamities since it spreads through contact with people, potentially increasing suspicion and distrust. We investigate the link between exposure to COVID-19 and trust in strangers in a representative sample of adults in Italy, one the countries hardest struck by the pandemic. Contrary to intuitive expectations, by conducting a panel study with an embedded survey experiment we find that those who report COVID-19 symptoms trust strangers substantially more than those who do not. Panel data analysis shows that trust increases within individuals who catch COVID-19, although the effect seems to decline once people recover. In addition, our experimental findings reveal that priming people on the risk that the COVID-19 pandemic poses to their health, leads to a substantial increase in trust in strangers, which lasts over time. Priming in terms of job loss and economic recession too leads to a smaller increase in trust in strangers, while solidarity appeals and knowledge of people with COVID-19 symptoms in one’s network has no effects on trust. These findings could be explained partly by people observing altruistic behavior and increasing their estimate of other people’s trustworthiness and partly by conjecturing that when caught in catastrophes people become more dependent on other people’s support and prone to “outward exposure”, consistently with the “emancipation theory of trust”.

Introduction: SARS-COV2 appears less frequently and less severely in the pediatric population than in older age groups. In the face of the urgent need to reactivate activities suspended during the lockdown, mainly those essential for child development, this study aims to describe the risks of death of persons infected with SARS-COV2 by age group and according to the presence of comorbidities. Methodology: We analyzed data of confirmed SARS-COV2 infection cases where symptoms began between February 22th, 2020, and March 31, 2021, as published by the General Epidemiology Direction (DGE) of the Mexican Ministry of Health. We calculated COVID-19 incidence and mortality by age group with population data from the Statistics and Population National Institute (INEGI), estimating the correlation between risk of death and the presence of comorbidities. Results: Mortality in SARS-COV2 infected people varied considerably, between 7 to 155 deaths per million per year in the under-20 age groups compared to 441 to 15929 in the older age groups. Mortality in pediatric populations is strongly associated with comorbidities (OR: 4.6- 47.9) compared to the milder association for older age groups (OR: 3.16-1.23). Conclusions: The risk of death from SARS-COV2 infection in children is low and strongly associated with comorbidities.

This study focuses on the Impact of COVID-19 on export-oriented economic growths of countries. We had tried to get the adjacent picture of the main affected areas of the world and their effects on economic growth. Pakistan also faced the harmful effects of this pandemic. The situation got worst when it was controlled with lockdown policies. It destabilized the vulnerable economy and economy shrinks down due to COVID-19. A mixed approach was conducted for this research study. As I have to see that to what degree the pandemic has affected the Pakistan’s economy and economic growth. The research aims to discover the impacts of COVID-19 on the export-oriented economic growth of Pakistan. The research methodology is based on a descriptive approach and a quantitative data analysis technique will be used to analyze the data. Other than human tragedy, the COVID – 19 has been an unpredicted shock for world economy Global Output estimated by IMF fallen by 3.5% in 2020 and all developed, undeveloped and under developing countries are hit by this wave hardly.

Objectives: Assess the impact of the illness designated COVID-19 during the first year of pandemic outbreak in Spain through age/sex-specific death rates. Study design: Age/sex-specific weeekly deaths in Spain were retrieved from Eurostat. Spanish resident population was obtained from the National Statistics Office. Methods: Generalized linear Poisson regressions were used to compute the contrafactual expected rates after one year (52 weeks or 364 days) of the pandemic onset. From this one-year age/sex-specific and age/sex-adjusted mortality excess rates were deduced. Results: For the past continued 13 years one-year age/sex-adjusted death rates had not been as high as the rate observed on February 28th, 2021. The excess death rate was estimated as 1.790<em>10<sup>-3</sup> (95% confidence interval, 1.773</em>10<sup>-3</sup> to 1.808<em>10<sup>-3</sup>; P-score=20.2% and z-score=11.4) with an unbiased standard deviation of the residuals equal to 157</em>10<sup>-6</sup> . This made 84 849 excess deaths (84 008 to 85 690). Sex disaggregation resulted in 44 887 (44 470 to 45 303) male excess deaths and 39 947 (39 524 to 40 371) female excess deaths. Conclusion: With 73 571 COVID-19 deaths and 9772 COVID-19 suspected deaths that occurred in nursing homes during the spring of 2020 it is only 1496 excess deaths (1.8%, a z-score of 0.2) that remains unattributed. The infection rate during the first year of the pandemic is estimated in 16% of population after comparing the ENE-COVID seroprevalence, the excess deaths at the end of the spring 2020 and the excess deaths at the end of the first year of the pandemic.

The rapid development of vaccines to prevent infection by SARS-CoV-2 virus causing COVID-19 makes necessary to compare the capacity of the different vaccines in terms of development of a protective humoral response. Here, we have used a highly sensitive and reliable flow cytometry method to measure the titers of antibodies of the IgG1 isotype in blood of volunteers after receiving one or two doses of the vaccines being administered in Spain. We took advantage of the multiplexed capacity of the method to measure simultaneously the reactivity of antibodies with the S protein of the original strain Wuhan-1 and the variant B.1.1.7 (Alpha). We found significant differences in the titer of anti-S antibodies produced after a first dose of the vaccines ChAdOx1 nCov-19/AstraZeneca, mRNA-1273/Moderna, BNT162b2/Pfizer- BioNTech and Ad26.COV.S/Janssen. Most important, we found a relative reduction in the reactivity of the sera with the B.1.1.7 versus the Wuhan-1 variant after the second boosting immunization. These data allow to make a comparison of different vaccines in terms of anti-S antibody generation and cast doubts about the convenience of repeatedly immunizing with the same S protein sequence.

The purpose of this research was to determine the relationship between fear of COVID-19 and anxiety in the Honduran population. This was made through a quantitative methodology, using the Fear of COVID-19 Scale (FCV-19S) and the Generalized Anxiety Disorder-7 (GAD-7). The sample consisted of 595 Honduran respondents, with a mean age of 25.10 years. The results suggest that female participants reported significantly higher scores in fear of COVID-19 and anxiety than men. A linear regression model determined that fear of COVID-19, sex and age were significant predictors of anxiety scores. The overall model had an r2 of 0.325, with fear of COVID-19 accounting for 29.9% of the variance in GAD-7 scores. The resulting model has a large effect size, f 2= 0.48. The results are discussed considering prior research and their psychosocial implications.

Objective: Cytokine storm and Coagulopathy have been implicated as major causes of morbidity and mortality in COVID-19 patients. A black yeast Aureobasidium pullulans AFO 202 strain produced beta 1,3 1,6 glucan has been reported to offer potential immune enhancement and metabolism balancing, as well as mitigation of coagulopathy risks. The N 163 strain produced beta glucan is an efficient anti-inflammatory immune modulator. In this pilot clinical study, we report the beneficial effects of these two beta glucans on the biomarkers for cytokine storm and coagulopathy in COVID-19 patients. Methods: A total of 24 RT PCR positive COVID 19 patients were recruited (Age range: 18~62; 17 males and 7 females). Patients were randomly divided into three groups (Gr): Gr. 1 control (n=8); Gr. 2: AFO-202 beta glucan (n=8); and Gr. 3, a combination of AFO-202 and N-163 beta glucans (n=8). All three groups received the standard care while groups 2 and 3 received additional supplementation of beta glucans for 30 days. In addition to basic clinical parameters, we periodically evaluated D Dimer, IL6, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), the neutrophil to lymphocyte ratio (NLR), the lymphocyte to CRP ratio (LCR) and the leukocyte CRP ratio (LeCR). Results: The duration of hospital stay for all three groups was nearly equivalent. There was no mortality of the subjects in any of the groups. Intermittent oxygen was administered from day of admission for up to four to five days with mask (two to four Lpm) to two subjects in Gr. 2 and one subject in Gr. 3. None of the subjects required ventilation. The D Dimer values in Gr. 1, which was on average 751 ng/ml at baseline, decreased to 143.89 ng/ml on day 15, but increased to 202.5 ng/ml on day 30, which in groups 2 and 3 decreased on day 15 and continued to remain at normal levels until day 30. IL6 levels decreased on day 15 from an average of 7.395 pg/ml to 3.16 pg/ml in the control, 26.18 pg/ml to 6.94 pg/ml in Gr. 2 and 6.25 pg/ml to 5.22 pg/ml in Gr. 3. However, when measured on day 30, in Gr. 1, the IL-6 increased to 55.37 pg/ml while there was only slight marginal increase in Gr. 2 but within normal range, and the levels further decreased to less than 0.5 pg/ml in Gr. 3. The same trend was observed with ESR. LCR and LeCR increased significantly in Gr. 3. NLR decreased significantly in groups 2 and 3. There was no difference in CRP within the groups. Conclusion: In this exploratory study, consumption of Aureobasidium pullulans produced beta glucans for thirty days, results in a significant control of IL6, D Dimer and NLR, a significant increase in LCR, LeCR and marginal control of ESR in COVID 19 patients. As these beta glucans are well known food supplements with decades of a track record for safety, based on these results, we recommend larger multi-centric clinical studies to validate their use as an adjunct in the management of COVID-19 and the ensuing long COVID-19 syndrome.

The daily number of new COVID-19 cases per capita is an important characteristic of the pandemic dynamics indicating the appearance of new waves (e.g., caused by new coronavirus strains) and indicate the effectiveness of quarantine, testing and vaccination. Since this characteristic is very random and demonstrates some weekly period, we will use the 7-days smoothing. The second year of the pandemic allows us to compare its dynamics in the spring and the summer of 2020 with the same period in 2021 and investigate the influence of seasonal factors. We have chosen some northern countries and regions: Ukraine, EU, the UK, USA and some countries located in tropical zone and south semi- sphere: India, Brazil, South Africa and Argentina. The dynamics in these regions was compared with COVID-19 pandemic dynamics in the whole world. Some seasonal similarities are visible only for EU and South Africa. In 2021, the southern countries demonstrated the exponential growth, but northern regions showed some stabilization trends.

Immunocompromised populations are at high risk for severe COVID-19. Vaccine-induced SARS-CoV-2 antibody responses are attenuated in solid organ transplant recipients (SOTRs), and breakthrough infections are more common. Additional SARS-CoV-2 vaccine doses may increase anti-spike antibody titers in some SOTRs, but whether this results in enhanced neutralizing capability, especially versus novel variants of concern (VOCs) that exhibit immune escape and higher infectivity (e.g., the Delta variant), is unclear. Here, we report that a third dose of a SARS-CoV-2 vaccine increases anti-SARS-CoV-2 spike and RBD IgG levels as well as plasma neutralizing capability versus VOCs, including Delta, in some SOTRs. However, anti-spike IgG and neutralizing capability remained significantly reduced compared to fully vaccinated healthy controls. These findings highlight the need for continued study of strategies to improve protection from COVID-19 in immunosuppressed populations as more SARS-CoV-2 VOCs emerge.

<li><strong>Associations between COVID-19 Risk Perceptions and Mental Health, Wellbeing, and Risk Behaviours</strong> -

<div>

Background: Mental health has worsened, and substance use has increased for some individuals during the coronavirus (COVID-19) pandemic. Cross-sectional studies suggest that COVID-19 risk perceptions are related to mental health and risk behaviours (potentially including substance use). However, longitudinal and genetic data are needed to support stronger inferences regarding whether these associations reflect causal pathways. Methods: Using cross-sectional, longitudinal, and polygenic risk score (PRS) data from the UK Avon Longitudinal Study of Parents and Children (ALSPAC), we examined cross-sectional and prospective associations between COVID-19 risk perceptions and mental health, wellbeing, and risk behaviours. Participants (85% female) were aged between 27-72 years. We used pandemic (April-July 2020) and pre-pandemic (2003-2017) data (ns = 233-5,115). Results: COVID-19 risk perceptions were positively associated with anxiety (OR 2.78, 95% confidence interval [CI] 2.20 to 3.52), depression (OR 1.65, 95% CI 1.24 to 2.18), low wellbeing (OR 1.76, 95% CI 1.45 to 2.13), increased alcohol use (OR 1.46, 95% CI 1.24 to 1.72), and COVID-19 prevention behaviours (ps < .05). Pre-pandemic anxiety (OR 1.64, 95% CI 1.29 to 2.09) and low wellbeing (OR 1.41, 95% CI 1.15 to 1.74) were positively associated with COVID-19 risk perceptions. The depression (b 0.21, 95% CI 0.02 to 0.40) and wellbeing (b -0.29, 95% CI -0.48 to -0.09) PRS were associated with higher and lower COVID-19 risk perceptions, respectively. Conclusions: Poorer mental health and wellbeing are associated with higher COVID-19 risk perceptions, and longitudinal and genetic data suggest that they may play a casual role in COVID-19 risk perceptions.

We examined how different types of communication influence people’s responses to health advice. Specifically, we tested whether presenting Covid-19 prevention advice (i.e., washing hands) as either originating from the government or a scientific source would affect people’s trust and intentions to comply with the advice. We also tested the effects of uncertainty framing: We presented the advice as being either certainly or potentially effective in reducing virus spread. To achieve this, we conducted an experiment using largely representative samples (N = 4,561) from the UK, US, Canada, Malaysia, and Taiwan. Overall, across countries, participants found messages more trustworthy when the purported source was science as opposed to government. This effect was stronger for left-wing/liberal participants. Phrasing the advice as certain versus uncertain had little impact on trust and intentions. Together, our findings suggest that health advice should be communicated by scientists rather than governments.

<li><strong>Religious Identity Cues Increase Vaccination Intentions and Trust in Medical Experts among American Christians</strong> -

Containing the COVID-19 pandemic in the U.S. requires mobilizing a large majority of the mass public to vaccinate, but many Americans are hesitant or opposed to vaccination. A significant predictor of vaccine attitudes in the U.S. is religiosity, with more religious individuals expressing more distrust in science and being less likely to get vaccinated. Here, we test whether explicit cues of common religious identity can help medical experts build trust and increase vaccination intentions. In a pre-registered survey experiment conducted with a sample of unvaccinated American Christians (N=1,765), we presented participants with a vaccine endorsement from a prominent medical expert (NIH Director, Francis Collins) and a short essay about doctors’ and scientists’ endorsement of the vaccines. In the common religious identity condition, these materials also highlighted the religious identity of Collins and many medical experts. Unvaccinated Christians in the common identity condition expressed higher trust in medical experts, greater intentions to vaccinate, and greater intentions to promote vaccination to friends and family than those who did not see the common identity cue. These effects were moderated by religiosity, with the strongest effects observed among the most religious participants, and statistically mediated by heightened perceptions of shared values with the medical expert endorsing the vaccine. These findings demonstrate the efficacy of common identity cues for promoting vaccination in a vaccine-hesitant subpopulation. More generally, the results illustrate how trust in science can be built through the invocation of common group identities, even identities often assumed to be in tension with science.

In December 2019, a novel illness called coronavirus disease 2019 (COVID 19) was described in China and became pandemic in a few months. The first case was detected in Argentina on March 3, 2020. A multicentre prospective observational cohort study on hospitalized patients with COVID 19 was conducted in 4 hospitals in San Isidro district from March 1, 2020 to October 31. Data was obtained by the attendant physician. 668 patients were included, the median age was 54 years, and 42.7% were female. Male sex and older age were associated with COVID 19 disease and more strongly with severity. Most frequent symptoms were fever and cough followed by dyspnoea, myalgia, odynophagia, headache, anosmia, and diarrhoea. Nonsevere patients had more upper respiratory symptoms while severe patients had mainly lower respiratory symptoms on admission. Most common comorbidities were arterial hypertension, diabetes, and cardiovascular disease. A great proportion of patients had normal thorax X ray and ground-glass opacity in tomography. In severe patients, radiography and tomography had a predominant ground glass pattern, but normal radiography and tomography on presentation were present in 22% and 5.9%, respectively. The absence of fever and normal radiology on admission neither excluded the disease nor further severity. PCR elevation was related with COVID 19 disease and with severity, while lymphopenia was more related with the disease and leukocytosis and thrombocytopenia with severity. 8, 4% of patients were health care workers. The mortality rate was 12.4%, 32.7% in severe patients and 61.2% in ventilated patients. Mortality was higher in the public hospital, probably associated with patients with older age and more comorbidities. All these observations can contribute to the knowledge of this disease in terms of diagnosis and prognosis.

More than a year after the COVID-19 pandemic has been declared, the need still exists for accurate, rapid, inexpensive and non-invasive diagnostic methods that yield high specificity and sensitivity towards the current and newly emerging SARS-CoV-2 strains. Several studies have since established saliva as a more amenable specimen type for early detection of SARS-CoV-2 as compared to nasopharyngeal swabs. Considering the limitations and high demand for COVID-19 testing, we employed MALDI-ToF mass spectrometry for the analysis of 60 gargle samples from human donors and compared the spectra with their COVID-19 status. Several standards including isolated human serum immunoglobulins and controls such as pre-COVID-19 saliva and heat inactivated SARS-CoV-2 virus were simultaneously analyzed to provide a relative view of the saliva and viral proteome as they would appear in this works methodology. Five potential biomarker peaks were established that demonstrated high concordance with COVID-19 positive individuals. Overall, the agreement of these results with RT-qPCR testing on NP swabs was no less than 90% for the studied cohort, which consisted of young and largely asymptomatic student athletes. From a clinical standpoint, the results from this pilot study are promising and suggest that MALDI-ToF can be used to develop a relatively rapid and inexpensive COVID-19 assay.
