The Coronavirus disease (COVID-19), that has gripped the world since December 2019 and declared a pandemic has infected about 4.8 million people in India and counting. This pandemic is urban-centric globally and in India in the earlier stages. In this paper we argue that the virus’s spread in India has multiple routes, the housing conditions, socio-economic characteristics as well as the epidemiology route that influences the management of the infection contrary to attributing the spread geography to only vulnerable areas. Selecting Ahmedabad, a city that register higher number of infections in the early period, this paper attempt to understand the pattern of infection spread and explain these using recorded infections from March 17, 2020 to June 10, 2020 period.

<li><strong>E-learning readiness and perceived stress among the university students of Bangladesh during COVID-19: a countrywide cross-sectional study</strong> -
|

<div>
|

Background: The COVID-19 pandemic has compelled all educational institutions from the conventional campus-based education system to e-learning worldwide. However, adapting to this new platform, e-learning readiness may cause perceived stress among students. This study aimed to examine the association between e-learning readiness and perceived e-learning stress and the relationship between sociodemographic and e-learning related factors. Results: A cross- sectional study was employed, where 1145 e-learning enrolled university students were surveyed. The result indicated that nearly 91% of students reported moderate (76.07%) to the higher level (14.85%) of perceived e-learning stress, whereas more than half of them (58.17%) were at the sub-optimum level of readiness. Furthermore, it was found that students with the sub-optimum level of readiness compared to optimum had a significantly higher chance of reporting a moderate and high level of perceived e-learning stress. Besides, parents’ highest education, residence, students’ preference in (e-learning or learning format), and having any eye problems were associated with perceived e-learning stress. Conclusions: A sudden introduction of e-learning during the COVID-19 catastrophe has brought about challenges, including the students’ readiness, that might exacerbate the perceived stress level in different ways. This study reported that most of the students were at sub-optimal levels of readiness and suffered from moderate to high levels of perceived e-learning stress. The findings should integrate into the education monitoring system to enhance students’ coping strategies, incite readiness, straighten and nourish existing policies.

Background: Raised of mucormycosis or black fungus cases middle of the COVID-19 pandemic, fear associated with black fungus may turn out to be a terrifying public health issue. This study aimed to assess the association between the fear and knowledge of black fungus and other determinants among healthcare workers in Bangladesh. Methods: From 25th May 2021 to 5th June 2021, a cross-sectional study was carried out among healthcare workers. For data collection during the COVID-19 pandemic, a semi-structured online questionnaire was used followed by convenient and snowball sampling methods. A multivariable linear regression model was fitted to assess the association between the fear and knowledge of black fungus and other determinants. Results: A total of 422 healthcare workers participated in this study. The results indicated that with the increased knowledge score of black fungus, the average score of black fungus fear was significantly increased (β = 0.35, 95% CI: 0.20, 0.50, p <0.001). Alongside, the respondents having insomnia had a higher score of black fungus fear compare to not having insomnia (β = 3.91, 95% CI: 2.49, 5.33, p <0.001) significantly. The gender, profession, and death due to COVID-19 of friends and family members had a significant effect on black fungus fear score increment. Conclusion: Even in the COVID-19 pandemic, the black fungus fear among healthcare workers may hinder their quality of life. Our study findings recommend an emphasis on the mental health aspects and ensure support to the healthcare workers so that they can tackle the ongoing situation with lesser frictions. Keywords: Mucormycosis, black fungus, COVID-19, fear, knowledge, insomnia, health workers.

The COVID-19 pandemic jeopardized the traditional academic learning calendars due to the closing of all educational institutions across the globe. To keep up with the flow of learning most of the educational institutions shifted toward e-learning. However, the questions of the students e-learning preference for various sub-domains of e-learning readiness did not identify, particularly among the female nursing students for a developing country like Bangladesh, where those domains pose serious challenges. A cross-sectional study was conducted among the female nursing students perceived e-learning readiness in sub-domains of readiness; availability of technology, use of technology, self-confidence, and acceptance. About 237 nursing students were recruited, who have enrolled in e-learning at least the last 30 days of the participation. A multivariable linear regression model was fitted to find the association between students preference and the perceived e-learning readiness with demographic and e-learning related factors. The findings of the study revealed that more than half of the students, 56.54% (n=134) did not prefer e-learning. The students did not prefer e-learning compared to prefer group has significantly less availability of technology (β = -3.01, 95% CI: -4.46, -1.56), less use of technology (β = -3.08, 95% CI: -5.11, -1.06), less self-confidence (β = -4.50, 95% CI: -7.02, -1.98), and less acceptance (β = -5.96, 95% CI: -7.76, -4.16). The age, degree, residence, parents highest education, having a single room, having any eye problems significantly associated with the variation of availability of technology, use of technology, self-confidence, and acceptance for e-learning. The outcomes of the study could be helpful while developing an effective and productive e-learning infrastructure regarding the preparedness of nursing colleges for the continuation of academia in any adverse circumstances like the COVID-19 pandemic.

Low- and middle-income countries are implementing COVID-19 vaccination strategies in light of varying vaccine efficacies and costs, supply shortages, and resource constraints. Here, we use a microsimulation model to evaluate clinical outcomes and cost-effectiveness of a COVID-19 vaccination program in South Africa. We varied vaccination coverage, pace, acceptance, effectiveness, and cost as well as epidemic dynamics. Providing vaccines to at least 40% of the population and prioritizing vaccine rollout prevented >9 million infections and >73,000 deaths and reduced costs due to fewer hospitalizations. Model results were most sensitive to assumptions about epidemic growth and prevalence of prior immunity to SARS-CoV-2, though the vaccination program still provided high value and decreased both deaths and health care costs across a wide range of assumptions. Vaccination program implementation factors, including prompt procurement, distribution, and rollout, are likely more influential than characteristics of the vaccine itself in maximizing public health benefits and economic efficiency.

The positivity rate of testing is currently used both as a benchmark of testing adequacy and for assessing the evolution of the COVID-19 pandemic. However, since the former is a prerequisite for the latter, its interpretation is often conflicting. We propose as a benchmark for COVID-19 testing effectiveness a new metric, termed “Severity Detection Rate” (SDR), that represents the daily needs for new Intensive Care Unit (ICU) admissions, per 100 cases detected (t-i) days ago, per 10,000 tests performed (t-i) days ago. Based on the announced COVID-19 monitoring data in Greece from May 2020 until August 2021, we show that beyond a certain threshold of daily tests, SDR reaches a plateau of very low variability that begins to reflect testing adequacy. Due to the stabilization of SDR, it was possible to predict with great accuracy the daily needs for new ICU admissions, 12 days ahead of each testing data point, over a period of 10 months, with Pearson r = 0.98 (p = 10-197), RMSE = 7,16. We strongly believe that this metric will help guide the timely decisions of both scientists and government officials to tackle pandemic spread and prevent ICU overload by setting effective testing requirements for accurate pandemic monitoring. We propose further study of this novel metric with data from more countries to confirm the validity of the current findings.

BACKGROUND: Growing evidence suggests that COVID-19 vaccines differ in effectiveness against breakthrough infection or severe COVID-19, but vaccines have yet to be investigated in controlled studies that head-to-head compare immunity of one to another. This study compared protection offered by the mRNA-1273 (Moderna) vaccine with that of the BNT162b2 (Pfizer-BioNTech) vaccine in Qatar. METHODS: In a population of 1,531,736 vaccinated persons, two matched retrospective cohort studies were designed and used to investigate differences in mRNA-1273 and BNT162b2 vaccine protection, after the first and second doses, from December 21, 2020 to October 20, 2021. RESULTS: After dose 1, cumulative incidence of breakthrough infection was 0.79% (95% CI: 0.75-0.83%) for mRNA-1273-vaccinated individuals and 0.86% (95% CI: 0.82-0.90%) for BNT162b2-vaccinated individuals, 21 days post-injection. Adjusted hazard ratio (AHR) for breakthrough infection was 0.89 (95% CI: 0.83-0.95; p=0.001). AHR was constant in the first two weeks at 1, but it declined to 0.67 (95% CI: 0.57-0.77; p<0.001) in the third week after dose 1. AHR for any severe, critical, or fatal COVID-19 was 0.71 (95% CI: 0.53-0.95; p=0.020). After dose 2, cumulative incidence was 0.59% (95% CI: 0.55-0.64%) for mRNA-1273-vaccinated individuals and 0.84% (95% CI: 0.79-0.89%) for BNT162b2-vaccinated individuals, 180 days post- injection. AHR for breakthrough infection was 0.69 (95% CI: 0.63-0.75; p<0.001) and was largely constant over time after dose 2. AHR for any severe, critical, or fatal COVID-19 was 0.37 (95% CI: 0.10-1.41; p=0.147). CONCLUSIONS: mRNA-1273 vaccination is associated with lower SARS-CoV-2 breakthrough infection and COVID-19 hospitalization and death than BNT162b2 vaccination, but the number of hospitalizations and deaths was exceedingly small for both vaccines. Both vaccines demonstrated strikingly similar patterns of build-up of protection after the first dose and waning of protection after the second dose.

We examined the phenomenon of fewer new confirmed cases of COVID-19 on Mondays in Japan, which we refer to as the Monday effect, and reveal the details of this effect. Specifically, we estimated the difference between the number of new positive cases that decreased over the weekend and the number of new confirmed cases that decreased at the beginning of the week. In Japan, prefectures aggregate and announce the number of confirmed daily cases. This analysis allows us to examine whether there is a Monday effect in each prefecture. We show that the Monday effect is due to the decreased number of inspections on the weekend appearing at the beginning of the week due to a time lag. Our results indicate that the administrative system causes delays in some prefectures, and that some prefectures are less likely to conduct screenings on holidays. Our results also suggest that delays generally occur in prefectures with a population of over 2 million.

Identity fusion with the community has been previously found to mediate altruism in post-disaster settings. However, whether this altruistic response is specifically triggered by ingroup threat, or whether it can also be triggered by global threats remains unclear. We evaluated willingness to sacrifice in the context of the covid-19 pandemic across three surveys waves. Against expectations, participants fused with the nation (vs. non-fused) did not differentially respond to a national vs. global threat condition. Conversely, social norms decisively influenced willingness to sacrifice in this sample, with fused individuals with stronger norms about social distancing reporting the highest altruistic response during the first weeks of the pandemic. Longitudinally, after an initial peak in the altruistic response, deteriorating social norms mediated decreases in willingness to sacrifice in individuals fused with the nation (versus non-fused). Implications of these results for the development of interventions aimed to address global challenges are discussed.

Objective: The unique constraints to everyday life brought about by the COVID-19 pandemic have been shown to negatively impact those with pre-existing mental health issues such as eating disorders. While individuals with eating disorders or disordered eating behaviours represent a vulnerable group to COVID-19 pandemic, the impact of the pandemic is yet to be fully established. As such, we systematically examined the impact of the COVID-19 pandemic on eating disorders and disordered eating behaviours. Method: We searched electronic databases MEDLINE, PsycINFO, CINAHL, and EMBASE for literature published until October 2021. Eligible studies were required to report on individuals with or without a diagnosed eating disorder or disordered eating behaviours who were exposed to the COVID-19 pandemic. Results: Seventy-two studies met eligibility criteria with the majority supporting an increase in eating disorder or disordered eating behaviours associated with the COVID-19 pandemic. Specifically, children and adolescents and individuals with a diagnosed eating disorder present a vulnerable group to the impacts of the COVID-19 pandemic. Discussion: This systematic review provides a timely insight into COVID-19 eating disorder literature and will assist in understanding possible future long-term impacts of the pandemic on eating disorders behaviours. It appears that the role of stress in the development and maintenance of eating disorders was intensified as a means to cope with the uncertainty of the pandemic. Future research is needed among understudied and minority groups and to examine the long-term implications of the COVID-19 pandemic on eating disorders and disordered eating behaviours.

A multidimensional index that measures the health status of individuals during the COVID-19 pandemic has been developed. The COVID-19 Health Status Scale (CHSS), a combination of previously studied and newly created health status scales, assesses the physical, mental, and social well-being of adults during the COVID-19 pandemic. The current study aimed to examine the differences between men and women in self-reported past major depressive disorder diagnosis during the COVID-19 lockdown in the United States using the CHSS self administered questionnaire. Participants were recruited using convenience sampling performed online through the SurveyMonkey Audience. The self-administered CHSS questionnaire has been pilot tested in an adult population during the COVID-19 pandemic lockdown in the US. The study sample size included 173 participants aged 18 years and older. Results revealed that almost one-third of the study participants (31.2%) reported being diagnosed with past major depressive disorder, whereas 68.8% reported no past major depressive disorder diagnosis. The results of the estimated coefficients of the logistic regression analysis test showed that men were less likely to report major depression during the COVID-19 lockdown (Exp (B) = 0.45 for men; p < 0.05) than women. Although the results showed that almost two thirds of the participants reported no major depression diagnosis during the COVID-19 lockdown, the logistic regression analysis confirmed that the chances of men reporting major depressive disorder diagnosis were lesser than that of women and this difference was statistically significant.

The sudden onset of the COVID-19 global health crisis and as-sociated economic and social fall-out has highlighted the im-portance of speed in modeling emergency scenarios so that ro-bust, reliable evidence can be placed in policy and decision-makers’ hands as swiftly as possible. For computational social scientists who are building complex policy models but who lack ready access to high-performance computing facilities, such time-pressure can hinder effective engagement. Popular and ac-cessible agent-based modeling platforms such as NetLogo can be fast to develop, but slow to run when exploring broad param-eter spaces on individual workstations. However, while deploy-ment on high-performance computing (HPC) clusters can achieve marked performance improvements, transferring models from workstations to HPC clusters can also be a technically challenging and time-consuming task. In this paper we present a set of generic templates that can be used and adapted by NetLogo users who have access to HPC clusters but require ad-ditional support for deploying their models on such infrastruc-ture. We show that model run-time speed improvements of be-tween 200x and 400x over desktop machines are possible using 1) a benchmark ‘wolf-sheep predation’ model in addition to 2) an example drawn from our own work modeling the spread of COVID-19 in Victoria, Australia. We describe how a focus on improving model speed is non-trivial for model development and discuss its practical importance for improved policy and de-cision- making in the real world. We provide all associated doc-umentation in a linked git repository.

Objective: The COVID-19 pandemic has drastically increased use of remote-delivered mental health services. This study identifies advantages and limitations of remote-delivered services on college campuses to inform mental health delivery post-pandemic. Methods: Clinicians (n = 30) were asked to evaluate COVID-19’s impact on their work, environment, and wellness in an online survey. Qualitative data was coded using a thematic analysis approach, while quantitative data was analyzed using descriptive statistics. Results: Many clinicians reported benefits of remote services, including increased accessibility, greater convenience, no change in therapeutic alliance, and decreased stress for clinicians. Clinicians also experienced challenges such as social isolation, technological difficulties, and personal/family concerns. Clinicians envisioned a hybrid service combining online and in-person activities post- pandemic. Conclusions: Overall, remote-delivered mental health services on college campuses have potential in increasing treatment quality while highlighting a necessity for further research in hybrid mental health delivery.

Quantitative polymerase chain reaction (qPCR) is a sensitive molecular method for the detection of genetic material and regarded as the gold-standard for diagnostic testing. To detect respiratory RNA virus infections, a reverse transcription (RT) step is implemented to create cDNA molecules that can serve as template in the qPCR step. However, positive RT-qPCR results can be found long after patient recovery, in part because the RT-qPCR can detect residual viral RNA genome fragments. To minimize the detection of such fragments, we here modified the RT-qPCR assay by replacing the routinely used random hexamers with an oligonucleotide that binds to the 39 end of the viral genome. We demonstrate that this method allows us to distinguish between infectious and non-infectious samples. Moreover, in clinical samples obtained over 15 days after the onset of symptoms, we observe that the modified RT-qPCR protocol yields significantly fewer positive results compared to a commercial RT-qPCR test. No significantly different results were found compared to the commercial test when SARS-CoV-2 clinical samples were tested within 5 days of the onset of symptoms, suggesting that the modification has a similar sensitivity for detecting infectious viral RNA. Overall, these findings may help differentiate between incorrectly-positive, persistently positive, and reinfection cases in COVID-19 patients.
