    Background: Healthcare workers are at increased risk of contracting SARS-CoV-2 and potentially causing institutional outbreaks. Staff testing is critical in identifying and isolating infected individuals while also reducing unnecessary workforce depletion. Tygerberg Hospital implemented an online pre-registration system to expedite staff and cluster testing. Objectives: We aimed to identify (1) specific presentations associated with a positive or negative result for SARS-CoV-2 and (2) staff sectors where enhanced strategies for testing might be required. Methods: Retrospective descriptive study involving all clients making use of the hospital's pre-registration system during May 2020. Results: Of 799 clients, most were young and female TRANS with few comorbidities. The most common occupation was nurses followed by administrative staff, doctors and general assistants. Doctors tested earlier compared to other staff (median: 1.5 vs 4 days). The most frequent presenting symptoms were headache MESHD headache HP, sore throat, cough MESHD cough HP and myalgia MESHD myalgia HP. Amongst those testing positive (n=105), fever MESHD fever HP, altered smell, altered taste sensation, chills MESHD chills HP and history of fever MESHD fever HP were the most common symptoms. Three or more symptoms was more predictive of a positive test, but 12/145 asymptomatic TRANS clients also tested positive. Conclusion: Staff coronavirus testing using an online pre-registration form is a viable and acceptable strategy. While some presentations are less likely to be associated with SARS-CoV-2 infection MESHD, no symptom can completely exclude it. Staff testing should form part of a bundle of strategies to protect staff including wearing masks, regular hand washing, buddy screening, physical distancing, availability of PPE and special dispensation for COVID-19-related leave.

    Background Clinical manifestations of coronavirus disease MESHD 2019 (COVID19) can vary from asymptomatic TRANS to profusely symptomatic due to many factors. Having data on the clinical characteristics of the affected patients is important for the screening and diagnosis of COVID-19. Main objective of this study is to evaluate the clinical and epidemiological characteristics and outcomes of patients with COVID-19 admitted to six treatment centres in Sri Lanka.Methods For the specific epidemic situation of COVID-19, we chose to conduct a descriptive retrospective study from six treatment centres in the country between March 10, 2020 and May 30, 2020.Results The study included 431 laboratory confirmed patients with COVID-19. Of them, 335 (78.2%) were males TRANS and their mean age TRANS was 37 years. Most patients (373: 86.5%) had had close contact TRANS with COVID-19 positive patients. The majority were asymptomatic TRANS (243: 56.3%) and of the symptomatic patients, the most common symptom was sore throat (81, 19%), followed by cough MESHD cough HP (72, 17%), headache MESHD headache HP (72, 17%), fever MESHD fever HP (50, 12%), and nasal discharge (36, 8%). Eight patients required either high dependency care or intensive unit care two of them succumbed to the illness (0.5%). Hydroxychloroquine (HCQ) was used as a treatment in 248 patients and they had a significantly longer (17.6 days) duration of hospital stays compared those who were not treated (13.6 days) with HCQ. When the HCQ was not used as a treatment, asymptomatic TRANS individuals had significantly shorter durations of hospital (11.1 days) stays compared to symptomatic individuals (14.3 days).Conclusions The majority of patients remained asymptomatic TRANS during the course of illness. The most common symptom was sore throat, seen in one fifth of patients, followed by cough MESHD cough HP, and headache MESHD headache HP. Our study also indicated the possibility of reduced viral clearance and hence longer duration of hospital stays with HCQ.

    Background: Novel coronavirus pneumonia MESHD pneumonia HP (NCP) is an emerging, highly contagious community acquired pneumonia MESHD pneumonia HP (CAP) caused by severe acute SARS-CoV-2. Nucleic acid test currently played a crucial role in diagnosis of suspected COVID-19 patients. However, a high false-negative rate of this “gold standard” test has been reported and posed a major setback in blocking the spread of the virus. We here aim to describe an optimized laboratory detection strategy to reduce the false negative rate. Methods: Suspected NCP patients were asked to collect both coughed MESHD coughed HP up specimen and pharyngeal swab. Samples from the same patient were mixed and tested at a single pool. SARS-CoV-2 was then detected by real-time RT-PCR using two different detection kits. Only if both results were negative was the test reported as negative. The patients will be excluded after two consecutive negative tests at 24 hour intervals. We also used multiplex PCR to detect 13 common respiratory tract pathogens (RTP). Results: Using this strategy, we confirmed 85 SARS-CoV-2 infections MESHD from 181 suspected patients, and 94.12% of patients were positive in the first test. The 96 excluded patients were followed up, and no additional NCP was found. We also found that 31.25% patients in 96 non-NCP patients were infected with at least one RTP that may cause CAP. Conclusion: Our studies suggest that dual reagents screening with pooled coughed MESHD coughed HP up specimen and pharyngeal swab samples reduced the false negative rate of nucleic acid testing. During the epidemic of NCP in Anhui province, there was a certain proportion of infection MESHD and co- infection MESHD of other common pathogens of CAP. In comparison with SARS-CoV-2 detection alone, combining multiple pathogen detection reduces the rate of miss diagnosis.

    Background: Coronavirus 2019 (COVID-19) is a novel infectious disease MESHD that was first reported in Wuhan, China, but has spread to all parts of the world. At the same time, because China has millions of HBV carriers TRANS, HBV infection MESHD has become a major public health problem in China. In this study, we aim to describe the clinical features of HBV carriers TRANS (AsC) infected with COVID-19 and to assess the factors that may affect the outcome during disease progression MESHD.Methods: This retrospective cohort study included 72 patients diagnosed with COVID-19 in Wuhan Jinyintan Hospital. These patients were also diagnosed as HBV carriers TRANS. The epidemiological characteristics, demographic features, clinical manifestations, laboratory test, treatment, management and final outcome were collected and analyzed.Results: The median age TRANS of 72 patients is 58.5 years old, of which 55.56% (n=40) are male TRANS. 20 (30.56%) patients were severe cases and 50 (69.44%) were non-severe cases. Fever MESHD Fever HP is the most common symptom, followed by cough MESHD cough HP, chest tightness HP and sputum. Laboratory test results including hematologic, biochemical, infection MESHD and coagulation parameters and several indicators, such as Aspartate Aminotransferase (AST), Total Bilirubin (TBil), Direct Bilirubin (DBil), Indirect Bilirubin (IBil), γ-glutamyl Transferase (GGT) showed difference between their admission and discharge. The level of Prealbumin (PA) and Serum SERO Amyloid A (SAA) in the study showed a significant trend from high to low, which has statistical significance.Conclusions: The clinical features of HBV carriers TRANS with COVID-19 have obvious systemic symptoms, such as fever MESHD fever HP, cough MESHD cough HP, and chest tightness HP. Compared with liver function data on admission and discharge, SARS-CoV-2 does not directly activate the Hepatitis B MESHD Hepatitis HP virus, and the risk of liver cell damage of HBV carriers TRANS with COVID-19 does not increase. Both PA and SAA are sensitive indicators and can be used to evaluate the prognosis and outcome of these patients.

    Objective: To examine the clinical characteristics and identify independent risk factors for in-hospital mortality of 2019 novel coronavirus (COVID-19) pneumonia MESHD pneumonia HP.Methods: A total of 156 patients diagnosed with COVID-19 pneumonia MESHD pneumonia HP at the central Hospital of Wuhan from January 29, 2020, to March 20, 2020 were enrolled in this single-centered retrospective study. Their epidemiological parameters, clinical presentations, underlying diseases MESHD, laboratory test results and disease MESHD outcomes were collected and analyzed. Results: The median age TRANS of enrolled patients was 66. Underlying diseases MESHD were identified in 101 patients, with hypertension MESHD hypertension HP being the most common one, followed by cardiovascular disease MESHD and diabetes. The most common symptoms identified upon admission were fever MESHD fever HP, cough MESHD cough HP, dyspnea MESHD dyspnea HP and fatigue MESHD fatigue HP. Compared to survival cases, patients who dead during hospitalization had higher plasma SERO levels of D-dimer, creatinine, creatine kinase, lactate dehydrogenase, lactate and lower percentage of lymphocytes (LYM [%]), platelet count and albumin levels. Most enrolled patients received anti-biotics and anti-viral treatment. In addition, 60 patients received corticosteroid and 51 received intravenous immunoglobulin infusion. 44 patients received noninvasive ventilation, 19 received invasive ventilation. Respiratory failure HP was the most frequently observed complication (106 [67.9%]), followed by sepsis MESHD sepsis HP (103 [66.0%]), acute respiratory distress HP syndrome MESHD (ARDS) (67 [42.9%]) and septic shock MESHD shock HP (50 [32.1%]). Multivariable regression suggested that advanced age TRANS (OR [odds ratio]= 1.059, 95% CI [confidence interval]: 1.011-1.110, P= 0.016) and elevated lactate level upon admission (OR= 2.411, 95% CI: 1.177-4.941, P= 0.016) were independent risk factors for in-hospital mortality for COVID-19 infection MESHD. Meanwhile, increased LYM (%) at admission (OR= 0.798, 95% CI: 0.728-0.876, P< 0.001) indicated a better prognosis. Conclusions: In this study, we discovered that age TRANS, LYM (%) and lactate level upon admission were independent factors that could influence in-hospital mortality rate.

    Background A striking characteristic of Coronavirus Disease MESHD 2019(COVID-19) is the coexistence of clinically mild and severe cases. A comprehensive analysis of multiple risk factors predicting progression to severity is clinically meaningful. Methods The patients were classified into moderate and severe groups. The univariate regression analysis was used to identify their epidemiological and clinical features related to severity, which were used as possible risk factors and were entered into a forward-stepwise multiple logistic regression analysis to develop a multiple factor prediction model for the severe cases.Results 255 patients (mean age TRANS, 49.1±SD 14.6) were included, consisting of 184 (72.2%) moderate cases and 71 (27.8%) severe cases. The common symptoms were dry cough MESHD cough HP (78.0%), sputum (62.7%), and fever MESHD fever HP (59.2%). The less common symptoms were fatigue MESHD fatigue HP (29.4%), diarrhea MESHD diarrhea HP (25.9%), and dyspnea MESHD dyspnea HP (20.8%). The univariate regression analysis determined 23 possible risk factors. The multiple logistic regression identified seven risk factors closely related to the severity of COVID-19, including dyspnea MESHD dyspnea HP, exposure history in Wuhan, CRP (C-reactive protein), aspartate aminotransferase (AST), calcium, lymphocytes, and age TRANS. The probability model for predicting the severe COVID-19 was P=1/1+exp (-1.78+1.02×age+1.62×high- transmission TRANS-setting-exposure +1.77×dyspnea+1.54×CRP+1.03×lymphocyte+1.03×AST+1.76×calcium). Dyspnea MESHD Dyspnea HP (OR=5.91) and hypocalcemia MESHD hypocalcemia HP (OR=5.79) were the leading risk factors, followed by exposure to a high- transmission TRANS setting (OR=5.04), CRP (OR=4.67), AST (OR=2.81), decreased lymphocyte count (OR=2.80), and age TRANS (OR=2.78). Conclusions This quantitative prognosis prediction model can provide a theoretical basis for the early formulation of individualized diagnosis and treatment programs and prevention of severe diseases MESHD.

    Background: Analyses of correlates of SARS-CoV-2 infection MESHD or mortality have usually assessed individual predictors. This study aimed to determine if patterns of combined predictors may better identify risk of infection TRANS risk of infection TRANS infection MESHD and mortality. Methods: For the period of March 2nd to 10th 2020, the first 9 days of the COVID-19 pandemic in Indonesia, we selected all 18 confirmed cases TRANS, of which 6 died, and all 60 suspected cases, of which 1 died; and 28 putatively negative patients with pneumonia MESHD pneumonia HP and no travel TRANS history. We recorded data for travel TRANS, contact history, symptoms, haematology, comorbidities, and chest x-ray. Hierarchical cluster analyses (HCA) and principal component analyses (PCA) identified cluster and covariance patterns for symptoms or haematology which were analysed with other predictors of infection MESHD or mortality using logistic regression. Results: For univariate analyses, no significant association with infection MESHD was seen for fever MESHD fever HP, cough MESHD cough HP, dyspnoea, headache MESHD headache HP, runny nose, sore throat, gastrointestinal complaints (GIC), or haematology. A PCA symptom component for fever MESHD fever HP, cough MESHD cough HP, and GIC tended to increase risk of infection TRANS risk of infection TRANS infection MESHD (OR 3.41; 95% CI 1.06 - 14; p=0.06), and a haematology component with elevated monocytes decreased risk (OR 0.26; 0.07 - 0.79; 0.027). Multivariate analysis revealed that an HCA cluster of 3-5 symptoms, typically fever MESHD fever HP, cough MESHD cough HP, headache MESHD headache HP, runny nose, sore throat but little dyspnoea and no GIC tended to reduce risk (aOR 0.048; <0.001 - 0.52; 0.056). In univariate analyses for death MESHD, an HCA cluster of cough MESHD cough HP, fever MESHD fever HP and dyspnoea had increased risk (OR 5.75; 1.06 - 31.3, 0.043), but no other individual predictor, cluster or component was associated. Other significant predictors of infection MESHD were age TRANS >= 45, international travel TRANS, contact with COVID-19 patient, and pneumonia MESHD pneumonia HP. Diabetes and history of contact were associated with higher mortality. Conclusions: Cluster groups and co-variance patterns may be stronger correlates of SARS-CoV-2 infection MESHD than individual predictors. Comorbidities may warrant careful attention as would COVID-19 exposure levels.

    SARS-CoV-2 causes multiple immune-related reactions at various stages of the disease MESHD. The wide variety of skin presentations has delayed linking these to the virus. Previous studies had attempted to look at the prevalence SERO and timing of SARS-COV-2 rashes but were based on mostly hospitalized severe cases and had little follow up. Using data collected on a subset of 336,847 eligible UK users of the COVID Symptom Study app, we observed that 8.8% of the swab positive cases (total: 2,021 subjects) reported either a body rash or an acral rash, compared to 5.4% of those with a negative swab test (total: 25,136). Together, these two skin presentations showed an odds ratio (OR) of 1.67 (95% confidence interval [CI]: 1.41-1.96) for being swab positive. Skin rashes HP were also predictive in the larger untested group of symptomatic app users (N=54,652), as 8.2% of those who had reported at least one classical COVID-19 symptom, i.e., fever MESHD fever HP, persistent cough MESHD cough HP, and/or anosmia HP, also reported a rash. Data from an independent online survey of 11,546 respondents with a rash showed that in 17% of swab positive cases, the rash was the initial presentation. Furthermore, in 21%, the rash was the only clinical sign. Skin rashes HP cluster with other COVID-19 symptoms, are predictive of a positive swab test and occur in a significant number of cases, either alone or before other classical symptoms. Recognising rashes is important in identifying new and earlier COVID-19 cases.

    Background: The SARS-CoV-2 virus may affect both adults TRANS and children TRANS. Although the disease MESHD, named COVID-19, has a lower prevalence SERO in infancy and has been described as mild, the clinical characteristics may vary and there is a possibility of complications. Objectives: To describe the clinical and epidemiological characteristics of pediatric cases confirmed TRANS in the state of Sinaloa, Mexico, during the first three months of the pandemic, and of children TRANS admitted with COVID-19 to a secondary hospital. Methods: This case series includes all patients with SARS-CoV-2 infection MESHD infection confirmed TRANS confirmed by PCR testing, identified in the state epidemiological surveillance system between March 1 and May 31, 2020. Confirmed patients admitted to the Sinaloa Pediatric Hospital (HPS) during the same dates are also described. Results: Fifty one children TRANS with SARS-CoV-2 were included, 10 of the admitted to HPS. The median age TRANS was 10 years. The more frequent symptoms were fever MESHD fever HP (78%), cough MESHD cough HP (67%) and headache MESHD headache HP (57%). Most cases were mild or asymptomatic TRANS. Three patients with comorbidities died. Only 4 of 10 patients identified in HPS had been admitted with the diagnosis of possible COVID-19. Conclusions: SARS-CoV-2 infection MESHD in children TRANS was mostly mild or asymptomatic TRANS, but with a wide range of clinical presentations.

    Background: Preventing communicable diseases MESHD requires understanding the spread, epidemiology, clinical features, progression, and prognosis of the disease MESHD. Early identification of risk factors and clinical outcomes might help to identify critically ill patients, provide proper treatment and prevent mortality. Methods: We conducted a prospective study in patients with flu-like symptoms referred to the imaging department of a tertiary hospital in IRAN between 3 March 2020 and 8 April 2020. Patients with COVID-19 were followed up to check their health condition after two months. The categorical data between groups were analyzed by Fisher exact test and continuous data by Wilcoxon Rank-Sum Test. Findings: 319 patients (mean age TRANS 45.48 years, 177 women) were enrolled. Fever MESHD Fever HP, dyspnea MESHD dyspnea HP, weakness, shivering HP, C-reactive protein (CRP), fatigue MESHD fatigue HP, dry cough MESHD cough HP, anorexia MESHD anorexia HP, anosmia HP, ageusia MESHD, dizziness MESHD, sweating and age TRANS were the most important symptoms of COVID-19 infection MESHD. Traveling TRANS in past three months, asthma MESHD asthma HP, taking corticosteroids, liver disease MESHD, rheumatological disease MESHD, cough MESHD cough HP with sputum, eczema MESHD eczema HP, conjunctivitis MESHD conjunctivitis HP, tobacco use, and chest pain MESHD chest pain HP did not have any relationship with COVID-19. Interpretation: Finding clinical symptoms for early diagnosis of COVID-19 is a critical part of prevention. These symptoms can help in the assessment of disease progression MESHD. To the best of our knowledge, some of the effective features on the mortality due to COVID-19 are investigated for the first time in this research. Funding: None
