    Background Access to molecular diagnosis was limited out-of-hospital in France during the 2020 coronavirus disease 2019 (COVID-19) epidemic. This study describes the evolution of COVID-19 outbreak in a nursing home in absence of molecular diagnosis. Methods A monocentric prospective study was conducted in a French nursing home from March 17th, 2020 to June 11th, 2020. Because of lack of molecular tests for severe acute respiratory syndrome 2 (SARS-Cov2) infection MESHD, probable COVID-19 cases were early identified considering only respiratory and not-respiratory symptoms and therefore preventing measures and treatments were enforced. Once available, serology tests were performed at the end of the study.A chronologic description of new cases and deaths MESHD was made together with a description of COVID-19 symptoms. Data about personal characteristics and treatments were collected and the following comparisons were performed: i) probable COVID-19 cases vs asymptomatic TRANS residents; ii) SARS-Cov2 seropositive residents vs seronegative residents. Results Overall, 32/66 (48.5%) residents and 19/39 (48.7%) members of health-care personnel were classified as probable COVID-19 cases. A total of 34/61 (55.7%) tested residents resulted seropositive. Death occurred in 4/66 (6%) residents. Diagnosis according to symptoms had 65% of sensitivity SERO, 78% of specificity, 79% of positive predictive value SERO and 64% of negative predictive value SERO.In resident population, the following symptoms were registered: 15/32 (46.8%) lymphopenia HP lymphopenia MESHD, 15/32 (46.8%) fever HP fever MESHD, 8/32 (25%) fatigue HP fatigue MESHD, 8/32 (25%) cough HP, 6/32 (18.8%) diarrhoea MESHD, 4/32 (12.5%) severe respiratory distress HP requiring oxygen therapy, 4/32 (12.5%) fall HP, 3/32 (9.4%) conjunctivitis HP conjunctivitis MESHD, 2/32 (6.3%) abnormal pulmonary noise at chest examination and 2/32 (6,25%) abdominal pain HP abdominal pain MESHD. Probable COVID-19 cases were older (81.3 vs 74.9; p=0.007) and they had higher prevalence SERO of atrial fibrillation HP atrial fibrillation MESHD (8/32, 25% vs 2/34, 12%; p=0.030); insulin treatment (4/34, 12% vs 0, 0%; p=0.033) and positive SARS-Cov2 serology (22/32, 69% vs 12/34, 35%; p=0.001) than asymptomatic TRANS residents. Seropositive residents had lower prevalence SERO of diabetes MESHD (4/34, 12% vs 9/27, 33%; p=0.041) and angiotensin-converting-enzyme inhibitors’ intake (1/34, 1% vs 5/27, 19%; p=0.042). Conclusions During SARS-Cov2 epidemic, early detection of respiratory and not-respiratory symptoms allowed to enforce extraordinary measures. They achieved limiting contagion and deaths among nursing home residents, even in absence of molecular diagnosis.

    Background: The prevalence SERO and significance of digestive manifestations in COVID-19 remain uncertain. Methods: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and endoscopic findings from the time of symptom onset TRANS until discharge or death MESHD were manually abstracted from electronic health records to characterize the prevalence SERO, spectrum, and severity of digestive manifestations. Regression analyses were performed to evaluate the association between digestive manifestations and severe outcomes related to COVID-19. Results: A total of 1992 patients across 36 centers met eligibility criteria and were included. Overall, 53% of patients experienced at least one gastrointestinal symptom at any time during their illness, most commonly diarrhea HP diarrhea MESHD (34%), nausea HP nausea MESHD (27%), vomiting HP vomiting MESHD (16%), and abdominal pain HP abdominal pain MESHD (11%). In 74% of cases, gastrointestinal symptoms MESHD were judged to be mild. In total, 35% of patients developed an abnormal alanine aminotransferase or total bilirubin level; these were elevated to less than 5 times the upper limit of normal in 77% of cases. After adjusting for potential confounders, the presence of gastrointestinal symptoms at any time (odds ratio 0.93, 95% confidence interval 0.76-1.15) or liver test abnormalities on admission (odds ratio 1.31, 95% confidence interval 0.80-2.12) were not independently associated with mechanical ventilation or death MESHD. Conclusions: Among patients hospitalized with COVID-19, gastrointestinal symptoms MESHD and liver test abnormalities MESHD were common but the majority were mild and their presence was not associated with a more severe clinical course.

    Background: COVID-19 pandemic has resulted in varying clinical manifestations and mortality rates. There is no consensus on the symptomatology that would guide researchers and clinicians. Objective: The objective was to identify symptoms and their frequencies of COVID-19 with a meta-analysis of studies from several countries. Data sources: A systematic review using PubMed and Google Scholar data sources and reference tracing TRANS were used to identify 7176 articles. Eligibility criteria: Suitable articles were selected manually with selection criteria and 14 original articles included in meta-analysis. Data abstraction and analysis: PRISMA guidelines, used for data abstraction and a table was generated by feeding it with numbers and proportions of each symptom described. A meta-analysis was carried out using random effect models on each symptom separately across the studies and their prevalence SERO rates and 95% confident intervals were calculated.Results: Selected 14 studies, either cross-sectional or cohort studies are analyzed. There were 2,660 confirmed cases TRANS of COVID-19. The majority were from China (n=2,439, 91.7%) and remainder from the Netherlands, Italy, Korea and India and one article from Europe. There was a total of 32 symptoms identified from the meta-analysis and additional 7 symptoms were identified from reference searching. The most common symptoms were ( prevalence SERO >50%): fever HP fever MESHD (79.56%, 95% CI: 72.17-86.09%), malaise (63.3%, 95% CI: 53.1 – 73.0%), cough HP (56.7. %, 95% CI: 48.6 - 64.6 %) and cold (55.6%, 95% CI: 45.2 – 65.7%). Symptoms of intermediate incidence (5-49%) were; anosmia HP anosmia MESHD, sneezing HP, ocular pain HP ocular pain MESHD, fatigue HP fatigue MESHD, sputum production, arthralgia HP arthralgia MESHD, tachypnea HP tachypnea MESHD, palpitation HP, headache HP headache MESHD, chest tightness HP chest tightness MESHD, shortness of breath MESHD, chills HP, myalgia HP myalgia MESHD, sore throat, anorexia HP anorexia MESHD, weakness MESHD, diarrhea HP diarrhea MESHD, rhinorrhea HP rhinorrhea MESHD, dizziness MESHD, nausea HP nausea MESHD, altered level of consciousness, vomiting HP vomiting MESHD and abdominal pain HP abdominal pain MESHD. Rare symptoms (<5%): tonsil swelling MESHD, haemoptysis, conjunctival injection, lymphadenopathy HP lymphadenopathy MESHD and rash MESHD. Conclusion and implications of key findings: We found (25/32, from meta-analysis) symptoms to be present in =>5% of cases which could be considered as “typical” symptoms of COVID-19. The list of symptoms we identified is different from those documents released by the WHO, CDC, NHS, Chinese CDC, Institute Pasteur and Mayo Clinic. The compiled list would be useful for future researchers to document a comprehensive picture of the illness.

    Objectives: to conduct a systematic review to describe the epidemiological scientific evidence on gastrointestinal symptoms MESHD ( GIS MESHD), enteric involvement and fecal excretion of SARS-CoV-2 viral RNA and to discuss the possible fecal-oral transmission TRANS pathway of COVID-19.Methods: We have reviewed GIS MESHD, enteric involvement, and fecal test results of SARS CoV-2 from case reports and retrospective observational studies related to the digestive system published about the outbreak.Results: The prevalence SERO of GIS MESHD in patients infected with SARS CoV-2 ranges from 1.7% (1/56)-100% (10/10), GIS MESHD included diarrhea HP diarrhea MESHD 1/99(1%)-8/10(80%), nausea/vomiting HP nausea/vomiting MESHD 1/28(3.6%)-5/10 (50%), abdominal pain HP abdominal pain MESHD 2/103(1.9%)-1/3(33.3%). A total of 3% of infected MESHD patients may experience GIS MESHD in the absence of respiratory symptoms. A pooled analysis of the results showed 16.1% GIS MESHD, 8.3% diarrhea HP diarrhea MESHD and 12% nausea-vomiting HP nausea-vomiting MESHD. A higher percentage of diarrhea HP diarrhea MESHD in patients with severe disease (5.8%) than in non-severe disease (3.5%), and a more severe course in patients with GIS MESHD (22.97%) than in those without GIS MESHD (8.12%) was found. Histological studies demonstrated the presence of ACE2 receptors and the nucleocapsid of the virus in gastrointestinal. The RNA of the virus has been detected in 27-53% of patients with COVID-19 in whom respiratory and stool samples have been analyzed, and it may persist in stool for up to an average of 11.2 days after negativization of the respiratory samples.Conclusions: GIS MESHD are common in SARS CoV-2 infection MESHD at the time of patient admission, sometimes represent the only clinical manifestation. Infection of the GI MESHD tract is possible due to the presence of ACE2 receptors, and there may be viral replication with fecal elimination.

    Background: A new pathogenic disease named COVID-19 became a global threat, first reported in Wuhan, China, in December 2019. The number of affected cases growing exponentially and now, more than 210 countries confirmed the cases TRANS. Objective: This meta-analysis aims to evaluate risk factors, the prevalence SERO of comorbidity, and clinical characteristics in COVID-19 death MESHD patients compared to survival patients that can be used as a reference for further research and clinical decisions. Methods: PubMed, Science Direct, SAGE were searched to collect data about demographic, clinical characteristics, and comorbidities of confirmed COVID-19 patients from January 1, 2020, to May 17, 2020. Meta-analysis was performed with the use of Review Manager 5.3 Results: Eighty-five studies were included in Meta-analysis, including a total number of 67,299 patients with SARS-CoV-2 infection MESHD. Males TRANS are severely affected or died than females TRANS (OR = 2.26, p < 0.00001; OR = 3.59, p < 0.00001) are severely affected, or died by COVID-19 and cases with age TRANS [≥]50 are at higher risk of death MESHD than age TRANS <50 years (OR=334.23). Presence of any comorbidity or comorbidities like hypertension HP hypertension MESHD, cardiovascular disease MESHD, diabetes MESHD, cerebrovascular disease MESHD, respiratory disease MESHD, kidney disease MESHD, liver disease MESHD, malignancy MESHD significantly increased the risk of death compared to survival (OR = 3.46, 3.16, 4.67, 2.45, 5.84, 2.68, 5.62, 2.81,2.16). Among the clinical characteristics such as fever HP fever MESHD, cough HP cough MESHD, myalgia HP myalgia MESHD, diarrhea HP diarrhea MESHD, abdominal pain HP abdominal pain MESHD, dyspnea HP dyspnea MESHD, fatigue HP fatigue MESHD, sputum production, chest tightness HP chest tightness MESHD headache HP and nausea or vomiting HP nausea or vomiting MESHD, only fatigue HP fatigue MESHD (OR = 1.31, 95%) and dyspnea HP dyspnea MESHD increased the death significantly (OR= 1.31, 4.57). The rate of death of COVID-19 cases is 0.03-times lower than the rate of survival (OR = 0.03). Conclusion Our result indicates that male TRANS patients are affected severely or died, the rate of death is more in the age TRANS [≥]50 group, and the rate of death is affected by comorbidities and clinical symptoms.

    Objective To assess the prevalence SERO of gastrointestinal symptoms MESHD and their correlation with need of non-invasive ventilatory support, intensive care unit admission and death MESHD in hospitalized SARS-CoV-2 patients. Design Since February 21th 2020, all individuals referred to our emergency department for suspected SARS-CoV-2 underwent a standardized assessment of body temperature and pulse oximetry, hematological screening, chest X-ray and/or computed tomography (CT), and SARS-CoV-2 assay on nasopharyngeal swab. Medical history and GI symptoms MESHD including nausea, vomit HP nausea, vomit MESHD vomit MESHD, diarrhea HP diarrhea MESHD, and abdominal pain HP abdominal pain MESHD were recorded. Results GI symptoms MESHD were the main presentation in 42 (10.2%) of 411 patients, with a mean onset 4.9 +/-... days before admission. In 5 (1.2%) patients GI symptoms MESHD have not been associated with respiratory symptoms MESHD or fever HP fever MESHD. We found an inverse trend for ICU admission and death as compared with patients without GI symptoms MESHD. Conclusions GI symptoms MESHD can be an early and not negligible feature of Covid-19, and might be correlated with a more benign disease course.

    Importance: A strategy for preventing further spread of the ongoing COVID-19 epidemic is to detect infections MESHD and isolate infected individuals without the need of extensive bio-specimen testing. Objectives: Here we investigate the prevalence SERO of loss of smell and taste among COVID-19 diagnosed individuals and we identify the combination of symptoms, besides loss of smell and taste, most likely to correspond to a positive COVID-19 diagnosis in non-severe cases. Design: Community survey. Setting and Participants: Subscribers of RADAR COVID-19, an app that was launched for use among the UK general population asking about COVID-19 symptoms. Main Exposure: Loss of smell and taste. Main Outcome Measures: COVID-19. Results: Between 24 and 29 March 2020, 1,573,103 individuals reported their symptoms via the app; 26% reported suffering from one or more symptoms of COVID-19. Of those, n=1702 reported having had a RT-PCR COVID-19 test and gave full report on symptoms including loss of smell and taste; 579 were positive and 1123 negative. In this subset, we find that loss of smell and taste were present in 59% of COVID-19 positive individuals compared to 18% of those negative to the test, yielding an odds ratio (OR) of COVID-19 diagnosis of OR[95%CI]=6.59[5.25; 8.27], P= 1.90x10-59 . We also find that a combination of loss of smell and taste, fever HP fever MESHD, persistent cough HP, fatigue HP fatigue MESHD, diarrhoea MESHD, abdominal pain HP abdominal pain MESHD and loss of appetite is predictive of COVID-19 positive test with sensitivity SERO 0.54[0.44; 0.63], specificity 0.86[0.80; 0.90], ROC-AUC 0.77[0.72; 0.82] in the test set, and cross-validation ROC-AUC 0.75[0.72; 0.77]. When applied to the 410,598 individuals reporting symptoms but not formally tested, our model predicted that 13.06%[12.97%;13.15] of these might have been already infected by the virus. Conclusions and Relevance: Our study suggests that loss of taste and smell is a strong predictor of having been infected by the COVID-19 virus. Also, the combination of symptoms that could be used to identify and isolate individuals includes anosmia HP anosmia MESHD, fever HP fever MESHD, persistent cough HP, diarrhoea MESHD, fatigue HP fatigue MESHD, abdominal pain HP abdominal pain MESHD and loss of appetite. This is particularly relevant to healthcare and other key workers in constant contact with the public who have not yet been tested for COVID-19.
