    Importance: Healthcare workers (HCWs), including those with mild symptoms, may be an important source of COVID-19 within elderly TRANS care. Objective: To gain insight into the spread of SARS-CoV-2 among HCWs working in elderly TRANS care settings. Design: Cross-sectional study among HCWs working in elderly TRANS care in the South-East of the Netherlands, testing for SARS-CoV-2, between March 31 and April 17, 2020. Setting: HCWs working in geriatric rehabilitation, somatic and psychogeriatric wards or small-scale living groups and district nursing, with a total of 5245 HCWs within 4 organisations. Participants: 621 HCWs with mild respiratory symptoms. Main Outcomes: Number of HCWs testing positive for SARS-CoV-2 in pharyngeal swabs, using real-time reverse-transcriptase PCR targeting the SARS-CoV-2 E-gene, N-gene, and RdRP. HCWs filled out a survey to collect information on symptoms and possible sources of infection MESHD. Results: 133/615 (21.6%) HCWs tested positive for SARS-CoV-2, ranging from 15.6 to 44.4% per elderly TRANS care organisation, and from 0 to 64.3% per separate location of the organizations, respectively. 74.6% of tested HCWs were nursing staff, 1.7% elderly TRANS care physicians, 20.3% other HCWs with patient contact and 3.4% HCWs without patient contact. In the univariate analysis, fever HP fever MESHD, runny or stuffy nose, anosmia HP anosmia MESHD, general malaise, myalgia HP myalgia MESHD, headache HP headache MESHD and ocular pain HP ocular pain MESHD were associated with SARS-CoV-2 positivity, while gastro-intestinal symptoms and respiratory symptoms, other than runny or stuffy nose were not. Risk factors for SARS-CoV-2 positivity were contact with patients or colleagues with suspected or proven COVID-19. Whole genome sequencing of 22 samples in 2 facilities strongly suggests spread within facilities. Conclusions and Relevance: We found a high SARS-CoV-2 prevalence SERO among HCWs in nursing homes and district nursing, supporting the hypothesis of undetected spread within elderly TRANS care facilities. Structural testing of elderly TRANS care HCWs, including track and trace of contacts TRANS, should be performed to control this spread, even when only mild symptoms are present.

    A novel coronavirus (SARS-CoV-2) has devastated the globe as a pandemic that has killed more than 800,000 people. Effective and widespread vaccination is still uncertain, so many scientific efforts have been directed towards discovering antiviral treatments. Many drugs are being investigated to inhibit the coronavirus main protease, 3CLpro, from cleaving its viral polyprotein, but few publications have addressed this proteases interactions with the host proteome or their probable contribution to virulence. Too few host protein cleavages have been experimentally verified to fully understand 3CLpros global effects on relevant cellular pathways and tissues. Here, we set out to determine this proteases targets and corresponding potential drug targets. Using a neural network trained on coronavirus proteomes with a Matthews correlation coefficient of 0.983, we predict that a large proportion of the human proteome is vulnerable to 3CLpro, with 4,460 out of approximately 20,000 human proteins containing at least one predicted cleavage site. These cleavages are nonrandomly distributed and are enriched in the epithelium along the respiratory tract, brain, testis, plasma SERO, and immune tissues and depleted in olfactory and gustatory receptors despite the prevalence SERO of anosmia HP anosmia MESHD and ageusia in COVID-19 patients. Affected cellular pathways include cytoskeleton/motor/cell adhesion proteins, nuclear condensation and other epigenetics, host transcription and RNAi, coagulation, pattern recognition receptors, growth factor, lipoproteins, redox, ubiquitination, and apoptosis. This whole proteome cleavage prediction demonstrates the importance of 3CLpro in expected and nontrivial pathways affecting virulence, lead us to propose more than a dozen potential therapeutic targets against coronaviruses, and should therefore be applied to all viral proteases and experimentally verified.

    Introduction: The corona virus disease 2019 is a disease caused by the newly discovered human infecting SARS-Co V-2 virus. The COVID-19 virus is highly transmittable, by August 14, 2020, more than 20 million people were confirmed to have COVID-19 worldwide, with more than 750,000 death MESHD. Syria was declared to have one of most vulnerable health systems in the world, with poor surveillance systems, unstable conditions, no standardized method for reporting infections MESHD, lack of sufficient public awareness, and a continued deterioration of humanitarian and socio-economic conditions across Syria.Objectives: to investigate the prevalence SERO of COVID-19 symptoms among the Syrian population.Methods: this is a cross sectional study in Damascus – Syria, data were collected during August, 2020 using an online questionnaire that contained 3 section (demographic variables, awareness of COVID-19, symptoms of COVID-19) and analyzed using SPSS v.22.Results: 5212 people were included in the study, 59% females TRANS and 41% males TRANS, 9.6% had chronic medical conditions. 63.4% reported experiencing COVID-19 symptoms during the past 6 months, symptoms lasted 6.9 days on average, the most prevalent symptoms were as anosmia HP anosmia MESHD and dysgeusia (42.2%), headache HP headache MESHD (67.1%), fatigue HP fatigue MESHD (70%). Symptoms were significantly more prevalent in the past 14 days (P=0.000).Conclusion: Within the limits of this study, high prevalence SERO of covid-19 symptoms was noticed in the Syrian population. Significant correlation was made between the severity and duration of the symptoms. Measures to slow down spread of COVID-19 need to be taken immediately.

    COVID-19 pandemic caused by SARS-CoV-2 led the Spanish government to impose a national lockdown in an attempt to control the spread of the infection MESHD. Mobility restrictions but also the requirement of a medical prescription to gain access to serological testing SERO for COVID-19 were included among the measures. Under this scenario, between April 15th to June 15th, 2020, we performed a seroprevalence SERO observational study including 449 individuals that fulfill prescription requirements: manifesting COVID-19 compatible symptoms, being in contact with a COVID-19 confirmed case TRANS or belonging to essential occupations including healthcare workers, firefighters or public safety personnel such as police. Importantly, none of the participants was hospitalized. Altogether, we studied this specific, non-commonly addressed cohort for SARS-CoV-2 seroprevalence SERO, uncovering intrinsic features of great demographic interest. The overall rate of IgG seropositivity was 33.69% (95% CI: 29.27 – 38.21). This seroprevalence SERO was comparable between different occupations performed by the participants. However, contacts with confirmed cases TRANS associated positively with IgG+ results, with stronger correlation if being a household member. The number of symptoms also correlated positively with IgG+ prevalence SERO. Ageusia/anosmia, pneumonia MESHD anosmia HP, pneumonia HP and cutaneous manifestations were the top-three symptoms that most strongly associated with IgG+ seroprevalence SERO. However, while pneumonia HP pneumonia MESHD and cutaneous manifestations were barely present in our cohort, fever HP fever MESHD, ageusia/anosmia MESHD anosmia HP and asthenia HP were the most frequently symptoms described within IgG+ subjects. Therefore, our data illustrate how specific cohorts display heterogeneous characteristics that should be taken into account when identifying population seroprevalence SERO against SARS-CoV-2 and key defining symptoms for COVID-19.

    Importance: Antibody testing SERO is important for understanding patterns of exposure and potential immunity to SARS-CoV-2. Prior data on seroprevalence SERO have been subject to variations in selection of individuals and nature as well as timing of testing in relation to exposures. Objective: We sought to determine the extent of SARS-CoV-2 seroprevalance and the factors associated with seroprevelance across a diverse cohort of healthcare workers. Design: Observational cohort study of healthcare workers, including SARS-CoV-2 serology testing and participant questionaires. Participants: A diverse and unselected population of adults TRANS (n=6,062) employed in a multi-site healthcare delivery system located in Los Angeles County, including individuals with direct patient contact and others with non-patient-oriented work functions. Exposure: Exposure and infection MESHD with the SARS-CoV-2 virus, as determined by seropositivity. Main Outcomes: Using Bayesian and multi-variate analyses, we estimated seroprevalence SERO and factors associated with seropositivity and antibody SERO titers, including pre-existing demographic and clinical characteristics; potential Covid-19 illness related exposures; and, symptoms consistent with Covid-19 infection MESHD. Results: We observed a seroprevalence SERO rate of 4.1%, with anosmia HP anosmia MESHD as the most prominently associated self-reported symptom in addition to fever HP fever MESHD, dry cough MESHD cough HP, anorexia HP anorexia MESHD, and myalgias HP myalgias MESHD. After adjusting for potential confounders, pre-existing medical conditions were not associated with antibody SERO positivity. However, seroprevalence SERO was associated with younger age TRANS, Hispanic ethnicity, and African-American race, as well as presence of either a personal or household member having a prior diagnosis of Covid-19. Importantly, African American race and Hispanic ethnicity were associated with antibody SERO positivity even after adjusting for personal Covid-19 diagnosis status, suggesting the contribution of unmeasured structural or societally factors. Notably, number of people, or children TRANS, in the home was not associated with antibody SERO positivity. Conclusion and Relevance: The demographic factors associated with SARS-CoV-2 seroprevalence SERO among our healthcare workers underscore the importance of exposure sources beyond the workplace. The size and diversity of our study population, combined with robust survey and modeling techniques, provide a vibrant picture of the demographic factors, exposures, and symptoms that can identify individuals with susceptibility as well as potential to mount an immune response to Covid-19.

    Background: Understanding of the true asymptomatic TRANS rate of infection of SARS-CoV-2 MESHD is currently limited, as is understanding of the population-based seroprevalence SERO after the first wave of COVID-19 within the UK. The majority of data thus far come from hospitalised patients, with little focus on general population cases, or their symptoms. Methods: We undertook enzyme linked immunosorbent assay SERO characterisation of IgM and IgG responses against SARS-CoV-2 spike glycoprotein and nucleocapsid protein of 431 unselected general-population participants of the TwinsUK cohort from South-East England, aged TRANS 19-86 (median age TRANS 48; 85% female TRANS). 382 participants completed prospective logging of 14 COVID-19 related symptoms via the COVID Symptom Study App, allowing consideration of serology alongside individual symptoms, and a predictive algorithm for estimated COVID-19 previously modelled on PCR positive individuals from a dataset of over 2 million. Findings: We demonstrated a seroprevalence SERO of 12% (51participants of 431). Of 48 seropositive individuals with full symptom data, nine (19%) were fully asymptomatic TRANS, and 16 (27%) were asymptomatic TRANS for core COVID-19 symptoms: fever HP fever MESHD, cough HP cough MESHD or anosmia HP anosmia MESHD. Specificity of anosmia HP anosmia MESHD for seropositivity was 95%, compared to 88% for fever HP fever MESHD cough HP and anosmia HP anosmia MESHD combined. 34 individuals in the cohort were predicted to be Covid-19 positive using the App algorithm, and of those, 18 (52%) were seropositive. Interpretation: Seroprevalence SERO amongst adults TRANS from London and South-East England was 12%, and 19% of seropositive individuals with prospective symptom logging were fully asymptomatic TRANS throughout the study. Anosmia HP demonstrated the highest symptom specificity for SARS-CoV-2 antibody SERO response. Funding: NIHR BRC, CDRF, ZOE global LTD, RST-UKRI/MRC

    Background. Healthcare workers (HCW) are at increased risk of being infected with SARS-CoV-2, yet limited information is available on risk factors of infection MESHD. Methods. We pooled data on occupational surveillance of 10,654 HCW who were tested for SARS-CoV-2 infection MESHD in six Italian centers. Information was available on demographics, job title, department of employment, source of exposure, use of personal protective equipment (PPE), and COVID-19-related symptoms. We fitted multivariable logistic regression models to calculate odds ratios (OR) and 95% confidence intervals (CI). Findings. The prevalence SERO of infection varied across centers and ranged from 3.0% to 22.0%, being strongly correlated with that of the respective areas. Women were at lower risk of infection TRANS risk of infection TRANS infection MESHD compared to men. Fever HP Fever MESHD, cough HP cough MESHD, dyspnea HP dyspnea MESHD and malaise were the symptoms most strongly associated with infection MESHD, together with anosmia HP anosmia MESHD and ageusia MESHD. No differences in the risk of infection TRANS risk of infection TRANS infection MESHD were detected between job titles, or working in a COVID-19 designated department. Reported contact with a patient inside or outside the workplace was a risk factor. Use of a mask was strongly protective against risk of infection TRANS risk of infection TRANS infection MESHD as was use of gloves. The use of a mask by the source of exposure (patient or colleague) had an independent effect in reducing infection risk TRANS infection risk TRANS.

    Objective: To evaluate the association of olfactory dysfunction MESHD ( OD MESHD) with hospitalization for COVID-19. Study Design: Multi-center cohort study. Setting: Emergency departments of thirteen COVID-19-designed hospitals in Kurdistan province, Iran. Subjects and Methods: Patients presenting with flu-like symptoms who tested positive by RT-PCR for COVID-19 between May 1st and 31st, 2020. At the time of presentation and enrollment, patients were asked about the presence of OD MESHD, fever HP fever MESHD, cough HP cough MESHD, shortness of breath MESHD, headache HP headache MESHD, rhinorrhea HP rhinorrhea MESHD and sore throat. The severity of OD MESHD was assessed on an 11-point scale from 0 (none) to 10 ( anosmia HP anosmia MESHD). Patients were either hospitalized or sent home for outpatient care based on standardized criteria. Results: Of 203 patients, who presented at a mean of 6 days into the COVID-19 disease course, 25 patients (12.3%) had new OD MESHD and 138 patients (68.0%) were admitted for their COVID-19. Patients admitted for COVID-19 had a higher prevalence SERO of all symptoms assessed, including OD MESHD (p<0.05 in all cases), and OD MESHD identified admitted patients with 84.0% sensitivity SERO and 34.3% specificity. On univariate logistic regression, hospitalization was associated with OD MESHD (odds ratio [OR] = 2.47, 95%CI: 1.085-6.911, p=0.049). However, hospitalization for COVID-19 was not associated with OD MESHD (OR=3.22, 95% CI: 0.57-18.31, p=0.188) after controlling for confounding demographics and comorbidities. Conclusion: OD MESHD may be associated with hospitalization for (and therefore more severe) COVID-19. However, this association between OD MESHD and COVID-19 severity is more likely driven by patient characteristics linked to OD MESHD, such as greater numbers of COVID-19 symptoms experienced or high-risk comorbidities.

    Background: Loss of smell and taste are common complaints in patients with the COVID-19 disease. These symptoms may present alone or with other symptoms. It is of utmost importance to know their rates of occurrence for better controlling of the infection MESHD. Objectives: To detect the prevalence SERO of anosmia HP anosmia MESHD and ageusia in individuals with COVID-19 in Al-Wajbah Primary Health Center, Doha, Qatar.Materials and methods: This retrospective study was conducted at Al-Wajbah Primary Health Center, Doha, Qatar. The study covered the two-month period -May and June 2020. The proven cases of COVID-19 by real-time PCR (Polymerase Chain Reaction) were enrolled in the study. Data regarding the age TRANS, gender TRANS, symptomatology including anosmia HP anosmia MESHD and ageusia, history of recent travel TRANS, smoking, past history of nasal and paranasal diseases (NPND), and severity of the disease were taken from the patients’ records. IBM- SPSS version 22 statistical software was used for the analysis of the data.Results: Out of 141, 35 (24.82%) subject presented with anosmia HP anosmia MESHD, ageusia MESHD or both. Most of the patients were from age group TRANS >30 year (n=104, 73.76%) with nearly equal gender TRANS. The majority of the individuals were without history of recent travel TRANS (92.2%) and smoking (80.14%). Three-quarters of the patients were asymptomatic TRANS, and 51.06% with a past history of NPND. The male TRANS sex, history of recent travel TRANS, smoking, and severe course of the disease were positive, highly significant association with anosmia HP anosmia MESHD or ageusia. All patients returned to their normal smell and taste sensations within a mean duration of 6.89 days.Conclusion: Loss of taste and smell were common symptomatology of COVID-19 disease. The males TRANS, recent travel TRANS, smoking, and severe course of the disease were risk factors of the anosmia HP anosmia MESHD and ageusia in COVID-19 cases.
