Introduction The study objective was to determine the breakthrough infection rate of Covid-19 (SARS-CoV-2) infection in those vaccinated with either BBV152 or AZD1222 (ChAdOx1-S) vaccine among healthcare workers (HCWs). Methods A cross-sectional analysis was conducted a medical college and hospital complex in Delhi, India through telephonic interviews among HCWs who had received at-least one dose of a Covid-19 vaccine during January to March 2021. Breakthrough infections were operationally defined as occurrence of Covid-19 infection ≥14 days after administration of two doses of either Covid-19 vaccine. Results We enrolled 325 HCWs with mean (SD) age of 29.1 (9.9) years including 211 (64.9%) males. Two seventy nine (85.8%) HCWs were fully vaccinated while 46 (14.2%) were partially vaccinated. There were 168 (51.7%) BBV152 and 157 (48.3%) AZD1222 (ChAdOx1-S) recipients. A total of 37 (11.3%, 95% C.I. 8.3, 15.3) breakthrough infections were observed in the HCWs. The median (IQR) time until incidence of Covid-19 breakthrough infection since receiving second dose of either Covid-19 vaccine was 47 (28.5, 55) days. Additionally, 20 (6.1%) non-breakthrough Covid-19 infections were recorded in the HCWs post vaccination with either a single dose of a Covid-19 vaccine or both doses but prior to a period of 14 days since administration of the second dose. Most breakthrough infection cases (94.4%) were mild and did not require supplemental oxygen therapy. HCWs without a history of natural Covid-19 infection and recovery prior to vaccination were 3.8 times more at risk to contract a Covid-19 infection or reinfection in spite of vaccination with at-least one dose of either Covid-19 vaccine. Conclusion Nearly one in nine HCWs experienced a Covid-19 breakthrough infection in the present study.
Background: Understanding the symptomatology and accuracy of clinical case definitions for COVID-19 in the community is important for the initiation of Test, Trace and Isolate (TTI) and may, in future, be important for early prescription of antivirals. Methods: Virus Watch is a large community cohort with prospective daily recording of a wide range of symptoms and self-reporting of swab results (mainly undertaken through the UK TTI System). We compared frequency, severity, timing, and duration of symptoms in test positive and test negative cases. We compared the test performance of the current UK case definition used by TTI (any one of: new continuous cough, high temperature or loss of or change in sense of smell or taste) with a wider definition that also included muscle aches or chills or headache or loss of appetite. Findings: We included results from 8213 swabbed illnesses, 944 of which tested positive for COVID-19. All symptoms were more common in swab positive than swab negative illnesses and symptoms were also more severe and of longer duration. Common symptoms such as cough, headache, fatigue, muscle aches and loss of appetite occurred early in the course of illness but were also very common in test-negative illnesses. Rarer symptoms such as fever or loss or altered sense of smell or taste were often not present but were markedly more common in swab positive compared to swab negative cases. The current UK definition had a sensitivity and specificity of 81% and 47% respectively for symptomatic COVID-19 compared to 93% and 26% for the broader definition. On average cases met the broader case definition one day earlier than current definition. 1.7-fold more illnesses met the broader definition than the current case definition. Interpretation: COVID-19 is difficult to distinguish from other respiratory infections and common ailments on the basis of symptoms. Broadening the list of symptoms used to encourage engagement with TTI could moderately increase the number of infections identified and shorten delays but with a large increase in the number of tests needed and in the number of people and contacts who do not have COVID-19 but might need to self-isolate whilst awaiting results.
Objectives: Concerns have been raised that the COVID-19 pandemic could increase risk for adverse mental health outcomes, especially in young adults, a vulnerable age group. We investigated changes in depression and anxiety symptoms (overall and severe) from before to during the pandemic, as well as whether these changes are linked to COVID-19 related stressors and pre-existing vulnerabilities in young adults followed in the context of a population-based cohort. Method: Participants (n=1039) from the Quebec Longitudinal Study of Child Development reported on their depression and anxiety symptoms and completed a COVID-19 questionnaire during the first wave of the COVID-19 pandemic in the summer of 2020 (age 22 years). Assessments at age 20 (2018) were used to estimate pre-pandemic depression and anxiety symptom severity. Results: While overall levels of depression and anxiety symptoms did not change, there was an increase in rates of severe depression (but not severe anxiety) from before (6.1%) to during (8.2%) the pandemic. Depressive and anxiety symptoms increased from before to during the COVID-19 pandemic among young adults with the lowest levels of symptoms before the pandemic, while they decreased among those with the highest levels of pre-existing symptoms. Youth who were living alone experienced an increase in depressive symptoms. Other COVID-19 related variables (e.g., loss of education/occupation, frequent news-seeking) and pre-existing vulnerabilities (e.g., low SES, low social support) were not associated with changes in depression or anxiety symptoms. Conclusion: Depression and anxiety symptoms in young adults from Quebec in Summer 2020 were comparable to symptoms reported in 2018. Most COVID-19 related stressors and pre-existing vulnerabilities were not associated with changes in symptoms. However, the increased rate of severe depression and the increase in depression and anxiety symptoms among young adults with the least mental health symptoms before the COVID-19 pandemic are concerning.
How might COVID-19 vaccines alter selection for increased SARS-CoV-2 virulence, or lethality? Framing current evidence surrounding SARS-CoV-2 biology and COVID-19 vaccines in the context of evolutionary theory indicates that prospects for virulence evolution remain uncertain. However, differential effects of vaccinal immunity on transmission and disease severity between respiratory compartments could select for increased virulence. To bound expectations for this outcome, we analyze an evo-epidemiological model. Synthesizing model predictions with vaccine efficacy data, we conclude that while vaccine driven virulence evolution remains a theoretical risk, it is unlikely to threaten prospects for herd immunity in immunized populations . Given that this event would nevertheless impact unvaccinated populations, virulence should be monitored to facilitate swift mitigation efforts.
Background: We conducted a systematic review and individual patient data (IPD) meta-analysis to evaluate the diagnostic accuracy of a commercial point-of-care test, the FebriDx lateral flow device (LFD), in adult patients with suspected COVID-19. The FebriDx LFD is designed to distinguish between viral and bacterial respiratory infection. Methods: We searched MEDLINE, EMBASE, PubMed, Google Scholar, LitCovid, ClinicalTrials.gov and preprint servers on the 13th of January 2021 to identify studies reporting diagnostic accuracy of FebriDx (myxovirus resistance protein A component) versus real time reverse transcriptase polymerase chain reaction (RT-PCR) testing for SARS-CoV-2 in adult patients suspected of COVID-19. IPD were sought from studies meeting the eligibility criteria. Studies were screened for risk of bias using the QUADAS-2 tool. A bivariate linear mixed model was fitted to the data to obtain a pooled estimate of sensitivity and specificity with 95% confidence intervals (95% CIs). A summary receiver operating characteristic (SROC) curve of the model was constructed. A sub-group analysis was performed by meta-regression using the same modelling approach to compare pooled estimates of sensitivity and specificity between patients with a symptom duration of 0 to 7 days and >7 days, and patients aged between 16 to 73 years and >73 years. Results: Ten studies were screened, and three studies with a total of 1481 patients receiving hospital care were included. FebriDx produced an estimated pooled sensitivity of 0.911 (95% CI: 0.855-0.946) and specificity of 0.868 (95% CI: 0.802-0.915) compared to RT-PCR. There were no significant differences between the sub-groups of 0 to 7 days and >7 days in estimated pooled sensitivity (p = 0.473) or specificity (p = 0.853). There were also no significant differences between the sub-groups of 16 to 73 years of age and >73 years of age in estimated pooled sensitivity (p = 0.946) or specificity (p = 0.486). Conclusions: Based on the results of three studies, the FebriDx LFD had high diagnostic accuracy for COVID-19 in a hospital setting, however, the pooled estimates of sensitivity and specificity should be interpreted with caution due to the small number of studies included, risk of bias, and inconsistent reference standards. Further research is required to confirm these findings, and determine how FebriDx would perform in different healthcare settings and patient populations.
Therapeutic efficacy in COVID-19 is dependent upon disease stage and severity (treatment effect heterogeneity). Unfortunately, definitions of severity vary widely. This compromises the meta-analysis of randomised controlled trials (RCTs) and the therapeutic guidelines derived from them. The World Health Organisation “living” guidelines for the treatment of COVID-19 are based on a network meta-analysis (NMA) of published RCTs. We reviewed the 81 studies included in the WHO COVID-19 living NMA and compared their severity classifications with the severity classifications employed by the international COVID-NMA initiative. The two were concordant in only 35% (24/68) of trials. Of the RCTs evaluated 69% (55/77) were considered by the WHO group to include patients with a range of severities (12 mild-moderate; 3 mild-severe; 18 mild-critical; 5 moderate-severe; 8 moderate-critical; 10 severe-critical), but the distribution of disease severities within these groups usually could not be determined, and data on the duration of illness and/or oxygen saturation values were often missing. Where severity classifications were clear there was substantial overlap in mortality across trials in different severity strata. This imprecision in severity assessment compromises the validity of some therapeutic recommendations; notably extrapolation of “lack of therapeutic benefit” shown in hospitalised severely ill patients on respiratory support to ambulant mildly ill patients is not warranted. Both harmonised unambiguous definitions of severity and individual patient data meta-analyses are needed to guide and improve therapeutic recommendations in COVID-19.
Host genetic variants influence the susceptibility and severity of several infectious diseases, and the discovery of novel genetic associations with Covid-19 phenotypes could help developing new therapeutic strategies to reduce its burden. Between May 2020 and February 2021, we used Covid-19 data released periodically by UK Biobank and performed over 400 Genome-Wide Association Studies (GWAS) of Covid-19 susceptibility (N=15,738 cases), hospitalization (N=1,916), severe outcomes (N=935) and death (N=828), stratified by ancestry and sex. In coherence with previous studies, we observed 2 independent signals at the chr3p21.31 locus (rs73062389-A, OR=1.22, P=7.64E-14 and rs13092887-A, OR=1.73, P=2.38E-8, in Europeans) modulating susceptibility and severity, respectively, and a signal influencing susceptibility at the ABO locus (rs9411378-A, OR=1.10, P =7.36E-10, in Europeans), which was more significant in men than in women (P=0.01). In addition, we detected 7 genome-wide significant signals in the last data release analyzed (on February 24th 2021), of which 4 were associated with susceptibility (SCRT2, LRMDA, chr15q24.2, MIR3681HG), 2 with hospitalization (ANKS1A, chr12p13.31) and 1 for severity (ADGRE1). Finally, we identified over 300 associations which increased in significance over time, and reached at least P<10-5 in the last data release analyzed. We replicated 2 of these signals in an independent dataset: a variant downstream of CCL3 (rs2011959) associated with severity in men, and a variant located in an ATP5PO intron (rs12482569) associated with hospitalization. These results, freely available on the GRASP portal, provide new insights on the host genetic architecture of Covid-19 phenotypes.
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 extirpate 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.

SARS-CoV-2 envelope protein causes acute respiratory distress syndrome (ARDS)-like pathological damages and constitutes an antiviral target - Cytokine storm and multi-organ failure are the main causes of SARS-CoV-2-related death. However, the origin of excessive damages caused by SARS-CoV-2 remains largely unknown. Here we show that the SARS-CoV-2 envelope (2-E) protein alone is able to cause acute respiratory distress syndrome (ARDS)-like damages in vitro and in vivo. 2-E proteins were found to form a type of pH-sensitive cation channels in bilayer lipid membranes. As observed in SARS-CoV-2-infected cells, heterologous expression of…

SARS-CoV-2 Nonstructural Protein 1 Inhibits the Interferon Response by Causing Depletion of Key Host Signaling Factors - Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the ongoing coronavirus disease 2019 (COVID-19) pandemic. While previous studies have shown that several SARS-CoV-2 proteins can antagonize the interferon (IFN) response, some of the mechanisms by which they do so are not well understood. In this study, we describe two novel mechanisms by which SARS-CoV-2 blocks the IFN pathway. Type I IFNs and IFN-stimulated genes (ISGs) were poorly induced during SARS-CoV-2…
Mechanism of Inhibition of the Reproduction of SARS-CoV-2 and Ebola Viruses by Remdesivir - Remdesivir is an antiviral drug initially designed against the Ebola virus.

Remdesivir exhibited far better efficacy when repurposed against SARS-CoV-2. The chemistry that accounts for this difference is the subject of this study. Here, we examine the hypothesis that remdesivir monophosphate (RMP)-containing RNA functions as a…
