In 731 persons seeking COVID-19 testing at a walk-up San Francisco community site in January 2022, simultaneous nasal rapid antigen testing (BinaxNOW(TM)) and RT-PCR testing was performed. There were 296 (40.5%) positive tests by RT-PCR; 98.5% of a random sample were the omicron variant. Sensitivity of a single antigen test was 95.2% (95% CI 92-98%); 82.1% (95% CI 77-87%) and 65.2% (95% CI 60-70%) for Ct threshold of < 30, < 35 and no threshold, respectively. We also compared BinaxNOW(TM) to RT- PCR from oral cheek swabs to nasal swabs (N=75); oral specimen was significantly less sensitive than nasal swab. A single BinaxNOW(TM) oral rapid antigen test failed to detect 91% (20 of 22) of specimens that were BinaxNOW(TM) positive from the standard nasal sampling. BinaxNOW(TM) continues to be a very useful diagnostic during the omicron surge. As currently recommended, repeat testing should be done for high- risk persons with an initial negative antigen test result.
Background Serological tests are widely used in various medical disciplines for diagnostic and monitoring purposes. Unfortunately, the sensitivity and specificity of test systems is often poor, leaving room for false positive and false negative results. However, conventional methods used to increase specificity decrease sensitivity and vice versa. Using SARS-CoV-2 serology as an example, we propose here a novel testing strategy: the “Sensitivity Improved Two- Test” or “SIT2” algorithm. Methods SIT2 involves confirmatory re-testing of samples with results falling in a predefined retesting-zone of an initial screening test, with adjusted cut-offs to increase sensitivity. We verified and compared the performance of SIT2 to single tests and orthogonal testing (OTA) in an Austrian cohort (1,117 negative, 64 post-COVID positive samples) and validated the algorithm in an independent British cohort (976 negatives, 536 positives). Results The specificity of SIT2 was superior to single tests and non-inferior to OTA. The sensitivity was maintained or even improved using SIT2 when compared to single tests or OTA. SIT2 allowed correct identification of infected individuals even when a live virus neutralization assay could not detect antibodies. Compared to single testing or OTA, SIT2 significantly reduced total test errors to 0.46% (0.24-0.65) or 1.60% (0.94-2.38) at both 5% or 20% seroprevalence. Conclusion For SARS-CoV-2 serology, SIT2 proved to be the best diagnostic choice at both 5% and 20% seroprevalence in all tested scenarios. It is an easy to apply algorithm and can potentially be helpful for the serology of other infectious diseases.
Objectives: We aimed to compare COVID-19 outcomes in the Omicron-driven fourth wave with prior waves in the Western Cape, the contribution of undiagnosed prior infection to differences in outcomes in a context of high seroprevalence due to prior infection, and whether protection against severe disease conferred by prior infection and/or vaccination was maintained. Methods: In this cohort study, we included public sector patients aged ≥20 years with a laboratory confirmed COVID-19 diagnosis between 14 November-11 December 2021 (wave four) and equivalent prior wave periods. We compared the risk between waves of the following outcomes using Cox regression: death, severe hospitalization or death and any hospitalization or death (all ≤14 days after diagnosis) adjusted for age, sex, comorbidities, geography, vaccination and prior infection. Results: We included 5,144 patients from wave four and 11,609 from prior waves. Risk of all outcomes was lower in wave four compared to the Delta-driven wave three (adjusted Hazard Ratio (aHR) [95% confidence interval (CI)] for death 0.27 [0.19; 0.38]. Risk reduction was lower when adjusting for vaccination and prior diagnosed infection (aHR:0.41, 95% CI: 0.29; 0.59) and reduced further when accounting for unascertained prior infections (aHR: 0.72). Vaccine protection was maintained in wave four (aHR for outcome of death: 0.24; 95% CI: 0.10; 0.58). Conclusions: In the Omicron-driven wave, severe COVID-19 outcomes were reduced mostly due to protection conferred by prior infection and/or vaccination, but intrinsically reduced virulence may account for an approximately 25% reduced risk of severe hospitalization or death compared to Delta.
Fewer COVID-19 deaths have been reported in this fourth wave, with clinicians reporting less admissions due to severe COVID-19 pneumonia when compared to previous waves. We therefore aimed to rapidly compare the profile of deaths in wave 4 with wave 3 using routinely collected data on admissions to public sector hospitals in the Western Cape province of South Africa. Findings show that there have been fewer COVID-19 pneumonia deaths in the Omicron-driven fourth wave compared to the third wave, which confirms anecdotal reports and lower bulk oxygen consumption by hospitals in the province.
RT-qPCR has been used as the gold standard method for detecting SARS-CoV-2 since early in the pandemic. At our university based high throughput screening program, we test all members of our community weekly. RT-qPCR cycle threshold (CT) values are inversely proportional to the amount of viral RNA in a sample, and thus are a proxy for viral load. We hypothesized that CT values would be higher, and thus the viral loads at the time of diagnosis would be lower in individuals who were infected with the virus but remained asymptomatic throughout the course of the infection. We collected the N1 and N2 CT values from 1633 SARS-CoV-2 positive RT-qPCR tests of individuals sampled between August 7, 2020, and March 18, 2021, at the BU Clinical Testing Laboratory. We matched this data with symptom reporting data from our clinical team. We found that asymptomatic patients had CT values significantly higher than symptomatic individuals on the day of diagnosis. Symptoms were followed by the clinical team for 10 days post the first positive test. Within the entire population, 78.1% experienced at least one symptom during surveillance by the clinical team (n=1276/1633). Of those experiencing symptoms, the most common symptoms were nasal congestion (73%, n=932, 1276), cough (60.0%, n=761/1276), fatigue (59.0%, n=753/1276), and sore throat (53.1%, n=678/1276). The least common symptoms were diarrhea (12.5%, n=160/1276), dyspnea on exertion (DOE) (6.9%, n=88/1276), foot or skin changes (including rash) (4.2%, n=53/1276), and vomiting (2.1%, n= 27/1276). Presymptomatic individuals, those who were not symptomatic on the day of diagnosis but became symptomatic over the following 10 days, had CT values higher for both N1 (median= 27.1, IQR 20.2- 32.9) and N2 (median=26.6, IQR 20.1-32.8) than the symptomatic group N1 (median= 21.8, IQR 17.2- 29.4) and N2 (median= 21.4, IQR 17.3- 28.9) but lower than the asymptomatic group N1 (median=29.9, IQR 23.6-35.5) and N2 (median= 30.0, IQR 23.1- 35.7). This study supports the hypothesis that viral load in the anterior nares on the day of diagnosis is a measure of disease intensity at that time.

SNX27 suppresses SARS-CoV-2 infection by inhibiting viral lysosome/late endosome entry - After binding to its cell surface receptor angiotensin converting enzyme 2 (ACE2), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters the host cell through directly fusing with plasma membrane (cell surface pathway) or undergoing endocytosis traveling to lysosome/late endosome for membrane fusion (endocytic pathway). However, the endocytic entry regulation by host cell remains elusive. Recent studies show ACE2 possesses a type I PDZ binding motif (PBM) through which it could…
SARS-CoV-2 main protease and papain-like protease inhibition by abietane-type diterpenes isolated from the branches of Glyptostrobus pensilis using molecular docking studies - Using various chromatographic methods, five abietane-type diterpenes were isolated from the branches of Glyptostrobus pensilis for the first time. The chemical structures of the isolates were identified by modern spectroscopic techniques, including ¹H and ^(13)C nuclear magnetic resonance spectroscopy and by comparison with the literature. In addition, the binding potential of the isolated compounds to replicase protein, SARS-CoV-2 main protease and papain-like protease, were examined using…
Molecular dynamics simulations of the flexibility and inhibition of SARS-CoV-2 NSP 13 helicase - The helicase protein of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is both a good potential drug target and very flexible. The flexibility, and therefore its function, could be reduced through knowledge of these motions and identification of allosteric pockets. Using molecular dynamics simulations with enhanced sampling, we determined key modes of motion and sites on the protein that are at the interface between flexible domains of the proteins. We developed an approach to…
Acriflavine, a clinically approved drug, inhibits SARS-CoV-2 and other betacoronaviruses - The COVID-19 pandemic caused by SARS-CoV-2 has been socially and economically devastating.

Using high-throughput screening, we identify acriflavine (ACF) as a potent papain-like protease (PL^(pro)) inhibitor. NMR titrations and a co-crystal structure confirm that acriflavine blocks the PL^(pro) catalytic pocket in an unexpected binding mode. We show…
Pathways and obstacles to social recovery following the elimination of SARS-CoV-2 from Aotearoa New Zealand: a qualitative cross-sectional study - CONCLUSIONS: Elimination strategies can successfully allow ‘normal social life’ to resume. However, this outcome is not guaranteed. People may encounter difficulties with re-establishing social connections in Zero-COVID settings. Measures designed to overcome such obstacles should be an integral part of elimination strategies.
Seroconversion following COVID-19 vaccination: Can we optimize protective response in CD20-treated individuals? - Although there is an ever-increasing number of disease-modifying treatments for relapsing multiple sclerosis (MS), few appear to influence COVID-19 severity. There is concern about the use of anti-CD20-depleting monoclonal antibodies, due to the apparent increased risk of severe disease following SARS-CoV-2 infection and inhibition of protective anti- COVID-19 vaccine responses. These antibodies are given as maintenance infusions/injections and cause persistent depletion of CD20+ B cells, notably…
Rapid SARS-CoV-2 Adaptation to Available Cellular Proteases - Recent emergence of SARS CoV-2 variants demonstrates the potential of this virus for targeted evolution, despite its overall genomic stability. Here we show the dynamics and the mechanisms behind the rapid adaptation of SARS-CoV-2 to growth in Vero E6 cells. The selective advantage for growth in Vero E6 cells is due to increased cleavage efficiency by cathepsins at the mutated S1/S2 site. S1/S2 site also constitutes a heparan sulfate (HS) binding motif that influenced virus growth in Vero E6…
MARCH8 Targets Cytoplasmic Lysine Residues of Various Viral Envelope Glycoproteins - The host transmembrane protein MARCH8 is a RING finger E3 ubiquitin ligase that downregulates various host transmembrane proteins, such as MHC-II. We have recently reported that MARCH8 expression in virus-producing cells impairs viral infectivity by reducing virion incorporation of not only HIV-1 envelope glycoprotein but also vesicular stomatitis virus G-glycoprotein through two different pathways. However, the MARCH8 inhibition spectrum remains largely unknown. Here, we show the antiviral…
The adaptation of SARS-CoV-2 to humans - The process of adaptation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to humans probably had started decades ago, when its ancestor diverged from the bat coronavirus. The adaptive process comprises strategies the virus uses to overcome the respiratory tract defense barriers and replicate and shed in the host cells. These strategies include the impairment of interferon production, hiding immunogenic motifs, avoiding viral RNA detection, manipulating cell autophagy, triggering…

Integrin/TGF-beta1 inhibitor GLPG-0187 blocks SARS-CoV-2 Delta and Omicron pseudovirus infection of airway epithelial cells which could attenuate disease severity - As COVID-19 continues to pose major risk for vulnerable populations including the elderly, immunocompromised, patients with cancer, and those with contraindications to vaccination, novel treatment strategies are urgently needed. SARS-CoV-2 infects target cells via RGD-binding integrins either independently or as a co-receptor with surface receptor angiotensin-converting enzyme 2 (ACE2). We used pan-integrin inhibitor GLPG-0187 to demonstrate blockade of SARS-CoV-2 pseudovirus infection of target…

IDENTIFICATION AND ALARM SYSTEM FOR FACIAL CORONA MASK USING CNN BASED IMAGE PROCESSING - tThe covid-19 epidemic is the world’s largest wake-up call for people to pay attention to their own and society’s health. One thing to keep in mind is that there is a segment of the population that has been exposed to the covid-19 virus and has generated antibodies without developing any significant illnesses and is continuing to be healthy. This indicates that a significant section of the population, even excluding the elderly, lacks the necessary bodily immunity to combat a Viral infection. As terrible as covid-19 is on a global scale, developing personal health standards and preventative measures for any pathogenic virus as a community would have spared many lives. In’this work, a camera is combined with an image processing system to recognise facial masks, which may be improved in a variety of ways. First and foremost, this method is meant to identify masks on a single person’s face. While this method is efficient in identifying someone has a mask, it does not ensure that they will wear it all of the time. The most effective update for this task is to install a camera with a wide field of view so that many individuals can be seen in the frame, and the faces of those who aren’t wearing markings can be identified, as well as the number of people and the timing. - link

REUNION OF PHOTOTHERMAL THERAPY WITH MXENE ADSORBED UREMIC TOXINS AND CYTOKINES: A SHILED FOR COVID-19 PATENTS - The COVID-19 pandemic has created havoc throughout the world. The disease has proved to be more fatalfor patients having comorbidities like diabetics, lungs and kidney infections, etc. In the case of COVID-19 patientsI having kidney injury, the. removal of uremic toxins from the blood is hindered and there is a rapid surge in the levelj of cytokine hormone resulting in the death of the patient in a short interval of time. To resolve this issue,iI; researchers have examined that the immediate removal of these toxins can improve the condition of the patient to a |greater extent. Studies have also found the presence of SARS CoV-2 viral RNAs in the blood of COVID-19patients, which risks their life as well as impacts the blood transfusion process, especially in the case ofasymptomatic patients. Hence it is required to control the surge of cytokines and uremic toxins as well as disinfectthe blood of the patient from the virus. MXenes, having a foam-like porous structure and hydrophilic negativesurface functionalization have greater adsorption efficiency as well as superior photothermal activity. Utilizingthese properties of MXenes, the MXene membranes can be used in the dialyzer that can help in the efficient andBiuick removal of the uremic toxins, cytokines, and other impurities from the blood. Along with this the greaterTJAdsorption efficiency of MXenes to amino acids result in the trapping of the SARS CoV-2 viruses on the surface J)3>f the MXene. Many researchers as well as the WHO have proved the efficient reduction of the viral copy numbersjjvith the increase of temperature. Hence, followed by the trapping of the viruses, the implementation of"Zphotothermal Therapy can result in the inactivation and denaturation of the viruses and their respective viral RNAsBJlby the produced heat. The same process can be repeated several times to get better results. This whole process canr>oQ-esult in impurity-free and infection-free blood, that can be returned back to the body of the patient or can be!— I Sitilized for the blood transfusion process without any risk of infection.IM - link
