Coronavirus disease 2019 (COVID-19), caused by Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has been declared as a global pandemic the World Health Organization (WHO). As is highly infectious, Global South countries are in vulnerable situation with high urban population density and lack of Water, Sanitation, Hygiene (WASH) services. The for slum dwellers low-income group clusters becoming worse. Lack health sanitation service availability already an issue them before beginning pandemic. So, it predictable that adopting this massive critical challenge them. This paper assesses gap slums, which become severe to tackle due COVID-19. study areas research Ranarmath Khema Khulna city, Bangladesh. SERVQUAL model used identify quality available these informal residential settlements. interpretation questionnaire survey data from two slums reveals one lacks Assurance Empathy, where other Tangibility Responsiveness.

COVID-19 is a pandemic viral disease with catastrophic global impact. This more contagious than influenza such that cluster outbreaks occur frequently. If patients symptoms quickly underwent testing and contact tracing, these could be contained. Unfortunately, have similar to other common illnesses. Here, we hypothesize the order of symptom occurrence help medical professionals distinguish from respiratory diseases, yet essential information largely unavailable. To this end, apply Markov Process graded partially ordered set based on clinical observations cases ascertain most likely discernible (i.e., fever, cough, nausea/vomiting, diarrhea) in patients. We then compared progression as influenza, SARS, MERS, observe if diseases present differently. Our model predicts initiates whereas like coronavirus-related fever. However, differs SARS MERS gastrointestinal symptoms. results support notion fever should used screen for entry into facilities regions begin reopen after outbreak Spring 2020. Additionally, our findings suggest good practice involve recording diseases. systemic had been standard since ancient perhaps transition local avoided.

As of June 2020, the number people infected with severe acute respiratory coronavirus 2 (SARS-CoV-2) continues to skyrocket, more than 6.7 million cases worldwide. Both World Health Organization (WHO) and United Nations (UN) has highlighted need for better control SARS-CoV-2 infections. However, developing novel virus-specific vaccines, monoclonal antibodies antiviral drugs against can be time-consuming costly. Convalescent sera safe-in-man broad-spectrum antivirals (BSAAs) are readily available treatment options. Here, we developed a neutralization assay using strain Vero-E6 cells. We identified most potent from recovered patients SARS-CoV-2-infected patients. also screened 136 infection in cells nelfinavir, salinomycin, amodiaquine, obatoclax, emetine homoharringtonine. found that combination orally virus-directed nelfinavir host-directed amodiaquine exhibited highest synergy.

Abstract Large-scale re-engineering of synonymous sites is a promising strategy to generate vaccines either through synthesis attenuated viruses or via codon-optimized genes in DNA vaccines. Attenuation typically relies on deoptimization codon pairs and maximization CpG dinucleotide frequencies. So as formulate evolutionarily informed attenuation strategies that aim force nucleotide usage against the direction favored by selection, here, we examine available whole-genome sequences SARS-CoV-2 infer patterns mutation selection sites. Analysis mutational profiles indicates strong bias toward U. In turn, analysis observed site composition implicates Accounting for effects reinforces this conclusion, UU content being quarter expected under neutrality. Possible mechanisms U mutations include higher expression, high mRNA stability lower immunogenicity viral genes. Consistent with gene-specific dinucleotides, observe systematic differences between We propose an approach that, unusually, seeks increase already most common codons. Comparable H1N1 Ebola finds GC3 deviated from neutral equilibrium not universal feature, cautioning generalization results.

In the context of current crises following COVID-19 and growing global economic uncertainties, issues regarding financial transactions with FINTECH are increasingly apparent. Consequently, in our opinion, utilization leads to a risk-reduction approach when contact other people. Moreover, can save up customers’ pecuniary funds. Therefore, during crises, applications be perceived as more competitive than traditional banking system. All above have provoked us conduct research related before after crisis outbreak. The aim article is present survey analysis individual customers Bulgaria. methodology includes questionnaire 242 respondents. For data processing, we implemented statistical measures quantitative methods, including two-sample paired t-tests, Levene’s test, ANOVAs performed through computer language Python web-based interactive computing environment for creating documents, Jupyter Notebook. findings bring out main implementation under conditions crisis. include identification problems
