SARS-CoV-2 variants of concern (VoC) show reduced neutralization by vaccine-induced and therapeutic monoclonal antibodies. We tested therapeutic equine polyclonal antibodies (pAbs) against four VoC (alpha, beta, epsilon and gamma). We show that equine pAbs efficiently neutralize VoC, suggesting they are an effective, broad coverage, low-cost and a scalable COVID-19 treatment.

Background Since 2018, there has been substantial progress with over 14 million people being treated for tuberculosis globally. However, the disease incidence and mortality are not falling fast enough to meet global targets, and, in addition, the COVID-19 pandemic threatens to counter the gains made in recent years. Pre-treatment loss to follow up is one of the factors that has been shown to contribute substantially to patient losses in the TB care cascade with subsequent high community transmission and mortality rates. This could be due to factors related to the patients as well as the health care workers. Therefore, conducting this review will enable us to identify, appraise and synthesize evidence on perspectives and experiences of patients and health care workers on pre-treatment loss to follow up in adults with pulmonary tuberculosis. Methods A search strategy will be developed using SPIDER (Sample, Phenomenon of interest, Design, Evaluation, Research Type) framework and the search will be conducted in relevant databases. Screening of titles, abstract and full articles will be done using pre-defined eligibility criteria. Purposeful sampling will be considered if there is a large volume of primary studies eligible for inclusion. Data will be extracted using a predesigned form and assessment of methodological limitations will be done using the Evidence for Policy and Practice Information (EPPI) center tool. Two of the review authors will independently do the screening, data extraction and assess methodological limitations. Any disagreements will be resolved through discussion and consensus. Data synthesis will be done using a pre-determined framework developed using Supporting the Use of Research Evidence (SURE) guidelines collaboration. Confidence of the review findings will be conducted using Confidence in the Evidence from Reviews of Qualitative Research (CERQual) approach and the findings presented in a summary table. Ethics and dissemination Findings of the qualitative evidence synthesis will be prepared using Enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) statement using relevant items for the qualitative synthesis. The findings will be published in a peer reviewed journal. The protocol will be registered with the International Prospective Register of Systematic Reviews (PROSPERO). Key words: Pre-treatment loss to follow up, pulmonary tuberculosis, perspectives, experiences, qualitative.

Background: Early detection of COVID-19 patients with potentially severe disease is crucial for predicting the disease9s course and prioritizing medical resources, lowering overall disease mortality. Objectives: To explore the role of hemogram-derived ratios and systemic-immune inflammation index (SII), in addition to C-reactive protein (CRP), in predicting COVID-19 severity and prognosis. Methods: In this retrospective study, data were collected from the medical records of 425 COVID-19 patients. Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and SII, together with the CRP, were investigated and compared. Results: NLR, PLR, SII, and CRP increased significantly in severe cases and with ICU admission (p ≤ 0.001). But, in non-survivors only NLR and CRP were significantly elevated (p < 0.05). By interpreting area under the receiver operating characteristic curve (ROC-AUC), CRP and NLR were better predictors of disease severity (AUC: 0.7 for both), the need for ICU admission (AUC: 0.763 and 0.727, respectively) and in-hospital mortality (AUC: 0.812 and 0.75, respectively). SII was significantly associated with the risk of severe disease development (odds ratio (OR): 3.143; 95% confidence interval (CI): 1.101-8.976); CRP (OR: 2.902; CI95%: 1.342-6.273) and NLR (OR: 2.662; CI95%, 1.072-6.611) were significantly associated with ICU admission risk; and only CRP was significantly associated with in-hospital mortality risk (OR: 3.988; CI95%: 1.460-10.892). Conclusions: Values of CRP, SII, and NLR at the time of hospital admission could be independent prognostic biomarkers to predict COVID-19 progression. The integration of CRP, SII, and NLR into prognostic nomograms may lead to improved prediction.

The government of Kenya has launched a phased rollout of COVID-19 vaccination. A major barrier is vaccine hesitancy; the refusal or delay of accepting vaccination. This study evaluated the level and determinants of vaccine hesitancy in Kenya. We conducted a cross-sectional study administered through a phone-based survey in February 2021 in four counties of Kenya. Multivariate logistic regression was used to identify individual perceived risks and influences, context-specific factors, and vaccine-specific issues associated with COVID-19 vaccine hesitancy. COVID-19 vaccine hesitancy in Kenya was high: 60.1%. Factors associated with vaccine hesitancy included: older age, lower education level, perceived difficulty in adhering to government regulations on COVID-19 prevention, less adherence to wearing of face masks, not having ever been tested for COVID-19, no reported socio-economic loss as a result of COVID public-health restriction measures, and concerns regarding vaccine safety and effectiveness. There is a need for the prioritization of interventions to address vaccine hesitancy and improve vaccine confidence as part of the vaccine roll-out plan. These messaging and/or interventions should be holistic to include the value of other public health measures, be focused and targeted to specific groups, raise awareness on the risks of COVID-19 and effectively communicate the benefits and risks of vaccines.

Background: COVID-19 mortality, severity, and recovery are major global concerns, but they are still insufficiently understood, particularly in the Middle East. Methods: This retrospective study comprised 180 adult Egyptian COVID-19 patients who were categorized and compared to evaluate if there was a link between their clinical and laboratory findings at hospital admission and disease severity and mortality risk. Results: Of all patients enrolled, 27.8% had severe disease and 13.9% died during their hospital stay. Diabetes mellitus (46.7%), hypertension (36.1%) and chronic obstructive pulmonary disease (COPD) (33.3%) were the most frequent associated co-morbidities. Severe patients and non-survivors were significantly older compared to their corresponding groups. Their absolute neutrophil count, procalcitonin (PCT), ESR, C-reactive protein (CRP), AST, ALT, LDH, D-dimer, and ferritin levels were all significantly higher (P ≤ 0.05), whereas their absolute lymphocyte count was significantly lower (P ≤ 0.05). COPD (OR: 3.294; 95% CI: 1.199-9.053; P= 0.021), diabetes mellitus (OR: 2.951; 95% CI:1.070-8.137; P= 0.037), ferritin ≥ 350 ng/mL (OR: 11.08; 95% CI: 2.796-41.551; P= 0.001), AST ≥ 40 IU/L (OR: 3.07; 95% CI: 1.842-7.991; P= 0.021), CT-SS ≥ 17 (OR: 1.205; 95% CI: 1.089-1.334; P ≤ 0.001) and absolute lymphocyte count < 1×103/μL (OR: 4.002; 95% CI: 1.537-10.421; P= 0.005), were all linked to a higher risk of COVID-19 severity. Furthermore, COVID-19 in-hospital mortality was predicted by dyspnea (OR: 4.006; 95% CI: 1.045-15.359; P= 0.043), CT-SS ≥ 17 (OR: 1.271; 95% CI: 1.091-1.482; P= 0.002) and AST ≥ 40 IU/L (OR: 2.89; 95% CI: 1.091-7.661; P= 0.033). Conclusions: Clinical and laboratory data of COVID-19 patients at their hospital admission may aid in identifying early risk factors for severe illness and a high mortality rate, as well as determining the most effective management for them.

Wastewater surveillance has emerged as a useful tool in the public health response to the COVID-19 pandemic. While wastewater surveillance has been applied at various scales to monitor population-level COVID-19 dynamics, there is a need for quantitative metrics to interpret wastewater data in the context of public health trends. We collected 24-hour composite wastewater samples from March 2020 through May 2021 from a Massachusetts wastewater treatment plant and measured SARS-CoV-2 RNA concentrations using RT-qPCR. We show that the relationship between wastewater viral titers and COVID-19 clinical cases and deaths varies over time. We demonstrate the utility of three new metrics to monitor changes in COVID-19 epidemiology: (1) the ratio between wastewater viral titers and clinical cases (WC ratio), (2) the time lag between wastewater and clinical reporting, and (3) a transfer function between the wastewater and clinical case curves. We find that the WC ratio increases after key events, providing insight into the balance between disease spread and public health response. We also find that wastewater data preceded clinically reported cases in the first wave of the pandemic but did not serve as a leading indicator in the second wave, likely due to increased testing capacity. These three metrics could complement a framework for integrating wastewater surveillance into the public health response to the COVID-19 pandemic and future pandemics.

Sensitive detection of IgG antibodies against SARS-CoV-2 is important to assessing immune responses to viral infection or vaccination and immunity duration. Antibody assays using non-invasive body fluids such as saliva could facilitate mass testing including young children, elderly and those who resist blood draws, and easily allowing longitudinal testing/monitoring of antibodies over time. Here, we developed a new lateral flow (nLF) assay that sensitively detects SARS-CoV-2 IgG antibodies in the saliva samples of vaccinated individuals and previous COVID-19 patients. The 25-minute nLF assay detected anti-spike protein (anti-S1) IgG in saliva samples with 100% specificity and high sensitivity from both vaccinated (99.51% for samples ≥ 19 days post 1st Pfizer/BioNTech or Moderna mRNA vaccine dose) and infected individuals. Antibodies against nucleocapsid protein (anti-NCP) was detected only in the saliva samples of COVID-19 patients and not in vaccinated samples, allowing facile differentiation of vaccination from infection. SARS-CoV-2 anti-S1 IgG antibody in saliva measured by nLF demonstrated similar evolution trends post vaccination to that in matching dried blood spot (DBS) samples measured by a quantitative pGOLD lab-test, enabling the nLF to be a valid tool for non-invasive personalized monitoring of SARS-CoV-2 antibody persistence. The new salivary rapid test platform can be applied for non-invasive detection of antibodies against infection and vaccination in a wide range of diseases.

The spread of SARS-CoV-2 is dependent on several factors, both biological and behavioral. The effectiveness of various non-pharmaceutical interventions can largely be attributed to changes in human behavior, but quantifying this effect remains challenging. Reconstructing the transmission tree of the third wave of SARS-CoV-2 infections in Iceland using contact tracing and viral sequence data from 2522 cases enables us to compare the infectiousness of distinct groups of persons directly. We find that people diagnosed outside of quarantine are 89% more infectious than those diagnosed while in quarantine, and infectiousness decreases as a function of the time spent in quarantine. Furthermore, we find that people of working age, 16-66 years old, are 47% more infectious than those outside that age range. Lastly, the transmission tree enables us to model the effect that given population prevalence of vaccination would have had on the third wave had they been administered before that time using several different strategies. We find that vaccinating in order of ascending age or uniformly at random would have prevented more infections per vaccination than vaccinating in order of descending age.

The emergence of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the resultant pandemic of coronavirus disease 2019 (COVID-19) has led to over one hundred million confirmed infections, greater than three million deaths, and severe economic and social disruption. Animal models of SARS-CoV-2 are critical tools for the pre-clinical evaluation of antivirals, vaccines, and candidate therapeutics currently under urgent development to curb COVID-19-associated morbidity and mortality. The golden (Syrian) hamster model of SARS-CoV-2 infection recapitulates key characteristics of severe COVID-19, including high-titer viral replication in the upper and lower respiratory tract and the development of pathogenic lesions in the lungs. In this work we examined the influence of the route of exposure, sex, and age on SARS-CoV-2 pathogenesis in golden hamsters. We report that delivery of SARS-CoV-2 primarily to the nasal passages (low-volume intranasal), the upper and lower respiratory tract (high-volume intranasal), or the digestive tract (intragastric) results in comparable viral titers in the lung tissue and similar levels of viral shedding during acute infection. However, low-volume intranasal exposure results in milder weight loss during acute infection while intragastric exposure leads to a diminished capacity to regain body weight following the period of acute illness. Further, we examined both sex and age differences in response to SARS-CoV-2 infection. Male hamsters, and to a greater extent older male hamsters, display an impaired capacity to recover from illness and a delay in viral clearance compared to females. Lastly, route of exposure, sex, and age were found to influence the nature of the host inflammatory cytokine response, but they had a minimal effect on both the quality and durability of the humoral immune response as well as the susceptibility of hamsters to SARS-CoV-2 re-infection. Together, these data indicate that the route of exposure, sex, and age have a meaningful impact SARS-CoV-2 pathogenesis in hamsters and that these variables should be considered when designing pre-clinical challenge studies.

Verbal harassment has become a major scourge of racism against people of Asian descent around the world during the Covid-19 pandemic. According to the national Stop AAPI Hate data, verbal harassment is the most common type of racism among Asian citizens. This behavior takes various forms: scolding, insulting, berating, expelling, yelling, forcing, threatening, and accusing. Therefore, it is necessary to analyze why Non-Asians do not tolerate verbal harassment of people of Asian descent which tends to increase during the Covid-19 pandemic. This study aims to provide information and solutions to the problem of xenophobia during the Covid-19 pandemic against non-Asians which led to acts of racism in the form of verbal harassment of citizens of Asian descent, as well as providing information about the history of racism against Asians, especially in the United States which has been going on for a long time. The method used in this study is a literature review technique from library sources for the last three years with the keywords verbal harassment, racism, and anti-Asian using a constructivism approach. The findings of the study is that the Covid-19 pandemic has built an understanding that non-Asian people have a higher rate than Asian descent who is accused of being the main source of the spread of the pandemic, resulting in inequality in society. simply because they are of a different race. The significance of this research focuses on the main causes of the emergence of a superior understanding of race as seen from the Constructivism approach. Where the bad view of the race of Asian descent is constructed through the influence of the surrounding environment which leads to acts of racism in the form of verbal harassment.

We developed an elaborated susceptible-infected-recovered (SIR) individual-based model (IBM) with pathogen strain drift, waning and cross immunity, implemented as a novel Java Runtime-Alterable-Model Platform (J-RAMP). This platform allows parameter values, process formulations, and scriptable runtime drivers to be easily added at the start of simulation. It includes facility for integration into the R statistical and other data analysis platforms. We selected a set of parameter values and process descriptions relevant to the current COVID-19 pandemic. These include pathogen-specific shedding, environmental persistence, host transmission and mortality, within-host pathogen mutation and replication, adaptive social distancing, and time dependent vaccine rate and strain valency specifications. Our simulations illustrate that if waning immunity outpaces vaccination rates, then vaccination rollouts may fail to contain the most transmissible strains. Our study highlights the need for adaptive vaccination rollouts, which depend on reliable real-time monitoring and surveillance of strain proliferation and reinfection data needed to ensure that vaccines target emerging strains and constrain escape mutations. Together with such data, our platform has the potential to inform the design of vaccination programs that eliminate rather than exacerbate local outbreaks. Finally, our RAMP concept promotes the development of highly flexible models that can be easily shared among researchers and policymakers not only addressing healthcare crises, but other types of environmental crises as well.

Several countries have implemented lockdowns to control their COVID-19 epidemic. However, questions like “where” and “when” still require answers. We assessed the impact of national and regional lockdowns considering the French first epidemic wave of COVID-19 as a case study. In a regional lockdown scenario aimed at preventing intensive care units (ICU) saturation, almost all French regions would have had to implement a lockdown within 10 days and 96% of ICU capacities would have been used. For slowly growing epidemics, with a lower reproduction number, the expected delays between regional lockdowns increases. However, the public health costs associated with these delays tend to grow exponentially with time. In a quickly growing pandemic wave, defining the timing of lockdowns at a regional rather than national level delays by a few days the implementation of a nationwide lockdown but leads to substantially higher morbidity, mortality and stress on the healthcare system.

This study investigates the impact of COVID-19 pandemic public closure orders on business listings for gay bars. Recent studies have shown gay bars to be quite vulnerable, with listings showing a 36.6% decline between 2007 and 2019. To supplement historic data from comprehensive printed listings, the Damron Guide, we conducted a census of online business listings. We verified each listing in the 2019 edition, also searching for new bars that were not included in that version. Results show that gay bar listings declined by 15.2% between 2019 and Spring 2021. This compares, however, to a 14.4% decline for 2017 and 2019, indicating a surprisingly stable rate of decline. This stability may be a methodological artifact, but may also reflect the relative resources of surviving gay bars going into pandemic, and/or their continuing vulnerability and precarity.

Background: Nigeria reported the first case of COVID-19 on February 27, 2020. By June of 2020, many people reported experiencing mild COVID-19 associated symptoms, yet did not get tested due to inaccessible testing and insufficient knowledge of the disease. There were media stories quoting grave diggers in Kano who reported high burial rates during this time. Methods: In order to draw more data on COVID-19 cases during this time period, we conducted a cross-sectional symptom survey in Kano, surveying 291 adults. Participants were asked to report demographic characteristics, past COVID-19 testing and symptoms, and community deaths. To assess associations between COVID-19 associated symptoms and socio-demographic characteristics, bivariate analyses using Chi-square tests were performed. A logistic regression assessing the association between any reported symptoms and the kind of work (indoor/outdoor) was done while adjusting for age, gender and education level. Results: Half of the respondents reported at least one symptom associated with COVID-19; the three most common symptoms were loss of appetite, cough, and fever. There was a statistically significant relationship between age group of the respondent and presence of COVID-19 associated symptoms. Gender or level of education did not have statistically significant association with COVID-19 associated symptoms among the respondents. People with outdoor occupations such as trading and hawking were more than twice as likely to report COVID-19 associated symptoms compared to those who were unemployed. Just under half of the respondents reported knowing someone who died in their community, with unexplained causes attributed to two-thirds of these cases. Our study found evidence of COVID-19 associated symptoms especially among the older population and unexplained deaths in Kano. Lack of confirmatory laboratory tests and absence of baseline vital statistics precluded us from finding definitive evidence for or against COVID-19 infection and associated mortality.

Abstract Background: Characterization of neutralization antibodies to SARS-CoV-2 infection or vaccination in children and young adults with inflammatory bowel disease (IBD) receiving biologic therapies is crucial. Methods: We performed a prospective longitudinal cohort study evaluating SARS-CoV-2 Spike protein receptor binding domain (S-RBD) IgG positivity along with consistent clinical symptoms in patients with IBD receiving infliximab or vedolizumab. Serum was also obtained following immunization with approved vaccines. IgG antibody to the spike protein binding domain of SARS-CoV-2 was assayed with a fluorescent bead-based immunoassay that takes advantage of the high dynamic range of fluorescent molecules using flow cytometry. A sensitive and high-throughput neutralization assay that incorporates SARS-CoV-2 Spike protein onto a lentivirus and measures pseudoviral entry into ACE2 expressing HEK-293 cells was used. Results: 436 patients were enrolled (mean age 17 years, range 2-26 years, 58% male, 71% Crohn disease, 29% ulcerative colitis, IBD-unspecified). 44 (10%) of enrolled subjects had SARS-CoV-2 S-RBD IgG antibodies. Compared to non-IBD adults (ambulatory) and hospitalized pediatric patients with PCR documented SARS-CoV-2 infection, S-RBD IgG antibody levels were significantly lower in the IBD cohort and by 6 months post infection most patients lacked neutralizing antibody. Following vaccination (n=33) patients had a 15-fold higher S-RBD antibody response in comparison to natural infection, and all developed neutralizing antibodies to both wild type and variant SARS-CoV-2. Conclusions and Relevance: The lower and less durable SARS-CoV-2 S-RBD IgG response to natural infection in IBD patients receiving biologics puts them at risk of reinfection. The robust response to immunization is likely protective.
