    Background: Coronavirus disease (COVID-19) represents an unprecedented challenge for both people and health systems. Latin America is the current epicentre of the pandemic; however, there is little published clinical information on the clinical characteristics and outcomes.Objective: To analyse the clinic characteristics, risk factors and evolution of the first cohort of hospitalised patients with confirmed infection TRANS by COVID-19 in 5 Colombian institutions.Methods: In the present retrospective observational study, information was acquired from consecutive hospitalized patients with a diagnosis of COVID-19 confirmed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) from March 01 to May 30, 2020 in Colombia.Results: A total of 44 patients were included. The median age TRANS was 62 years, and 65.9% of the patients were male TRANS. A total of 69.8% of the patients were overweight HP or obese MESHD, and 13.6% of the patients had high blood SERO pressure and diabetes MESHD. The presence of systemic symptoms and cough HP cough MESHD were the most common. Ground-glass opacity was frequent finding upon chest imaging. The 30-day mortality rate was 47.7% with a median of 11 days. The composite outcome (critical care requirement, mechanical ventilation and death MESHD) occurred in 36.4% of the patients. The biomarkers associated with mortality risk included troponin higher than 14 ng/L (RR: 5.25; 95% CI 1.37-20.1, p = 0.004) and D-dimer higher than 1000 ng/ml (RR: 3.0; 95% CI 1.4-6.3, p = 0.008). Cardiovascular complications MESHD, acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD) and acute kidney injury HP acute kidney injury MESHD were the most frequent comorbidities in patients with severe pneumonia HP pneumonia MESHD.Conclusion: The clinical course of SARS-CoV-2 infection MESHD diagnosis confirmed by RT-PCR in Colombian patients admitted to a high-complexity hospital was similar to that reported in the literature; however, the population was characterised by a more advanced stage of the infection MESHD

    BackgroundThe outbreak of the 2019 novel coronavirus since December, 2019, has now causing nearly 75 thousand confirmed cases TRANS in China (until paper preparing). This epidemic has posed significant threats to international health and the economy. Zhejiang province, which once had the 2nd most accumulative cases among all provinces, has now dropped to top No.5 (until paper preparing). It had a high discharge rates (43.86%) from hospital and the lowest death rate among all top 5 epidemic provinces, this drew our attention to the epidemiological, clinical characteristics and local government engagement of this region.MethodsIn this study, we included all confirmed cases TRANS of COVID-19 pneumonia HP pneumonia MESHD in Zhejiang province from Jan 21 to Feb 11, 2020. All data come from cases issued by Zhejiang provincial health commission.ResultsUntil Feb 11, 2020, 1143 cases were confirmed TRANS in Zhejiang province. We analysed the cases growth information in Zhejiang province and age TRANS, gender TRANS, severe cases percent, the source of the patients, the time of disease onset to confirm and the clinical symptoms of the patients. We also compared the clinical symptoms of elders and the young.ConclusionsThe patients in Zhejiang province had no age TRANS and gender TRANS preference, and the average time of disease onset to confirm was 5.9 days. The clinical symptoms were mainly fever HP, cough HP cough MESHD and weakness MESHD, similarly with before reported. The difference between elders and younger are not significant. Until paper preparing, Zhejiang province has very high discharge rate and low death MESHD rate, low cases increase rate in China.

    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.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 HP Fever MESHD is the most common symptom, followed by cough HP, chest tightness HP chest tightness MESHD 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 HP fever MESHD, cough HP cough MESHD, and chest tightness HP chest tightness MESHD. Compared with liver function data on admission and discharge, SARS-CoV-2 does not directly activate the Hepatitis HP Hepatitis MESHD B 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.

    Background: Prolonged nucleic acid conversion and false-negative results of real-time reverse transcription polymerase chain reaction (RT-PCR) might occur in some patients with COVID-19 rather than recurrence of infection MESHD. Here, we reported four cases of COVID-19 with prolonged nucleic acid conversion and false-negative results of RT-PCR in our institution.Case presentation: Case 1: A 36-year-old- male TRANS patient complained of coughing HP up phlegm one week before admission. His chest X-rays showed mild pneumonia HP pneumonia MESHD in the right lung. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also had negative results of RT-PCR twice (the 6th and 8th tests) from a total of 11 swab tests. Case 2: A 54-year-old- male TRANS patient complained of shortness of breath MESHD that worsened with activity. He had a comorbidity of diabetes MESHD. His chest X-rays showed inhomogeneous opacity on bilateral paracardial and lateral aspects. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also had negative results of RT-PCR once (the 5th test) from a total of 8 swab tests. Case 3: A 47-year-old man presented with complaints of fever HP fever MESHD, cough HP cough MESHD, sore throat, and diarrhea HP diarrhea MESHD. He had comorbidities of asthma HP asthma MESHD and heart rhythm disorders MESHD. His chest X-rays showed bilateral pneumonia HP pneumonia MESHD. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also showed negative results of RT-PCR twice (the 4th and 6th tests) from a total of 11 swab tests. Case 4: A 56-year-old- female TRANS complained of lethargy HP lethargy MESHD and diarrhea HP diarrhea MESHD. She has a history of hyperthyroidism HP hyperthyroidism MESHD. His chest X-rays showed bilateral pneumonia HP pneumonia MESHD. She was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, she also had negative results of RT-PCR twice (the 2nd and 10th tests) from a total of 14 swab tests.Conclusions: Our cases further confirmed TRANS the occurrence of prolonged nucleic acid conversion and the possibility of false negative results of RT-PCR in patients with COVID-19 instead of recurrence of infection MESHD. These findings might have an implication on the management of patients with COVID-19 who have already clinically and radiologically recovered, particularly related to subsequent spreading of the infection MESHD in the community.

    Data on the novel coronavirus disease MESHD 2019 (COVID-19) in children TRANS are limited, and studies from Europe are scarce. We analyzed the clinical severity and epidemiologic aspects of COVID-19 in consecutive children TRANS aged TRANS 0 – 18 years, referred with a suspicion of COVID-19 between February 1, and April 15, 2020. RT-PCR on a nasopharyngeal swab was used to confirm COVID-19. 319 children TRANS met the criteria of a suspected case. COVID-19 was diagnosed in 15/319 (4.7%) patients (8 male TRANS; mean age TRANS 10.5 years). All of them had household contact TRANS with an infected relative. Five (33.3%) patients were asymptomatic TRANS. In 9/15 (60.0%) children TRANS, the course of the disease was mild, and in 1/15 (6.7%), it was moderate, with the following symptoms: fever HP fever MESHD (46.7%), cough HP (40%), diarrhea HP diarrhea MESHD (20%), vomiting HP vomiting MESHD (13.3%), rhinitis HP rhinitis MESHD (6.7%), and shortness of breath MESHD (6.7%). In the COVID-19-negative patients, other infections were confirmed TRANS infections were confirmed MESHD, including influenza in 32/319 (10%). The clinical course of COVID-19 and influenza differed significantly based on the clinical presentation. In conclusion, the clinical course of COVID-19 in children TRANS is usually mild or asymptomatic TRANS. In children TRANS suspected of having COVID-19, other infections should not be overlooked. The main risk factor for COVID-19 in children TRANS is household contact TRANS with an infected relative.

    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.

    Background Symptoms of the novel coronavirus disease MESHD (COVD-19) are well known, although asymptomatic TRANS cases were also reported due to this rapidly evolving viral disease. However, there has been limited research with inconsistent findings on symptoms of COVID-19 and diseases severity. We aimed to evaluate the association between symptoms and severity of disease in confirmed COVID-19 cases by performing a meta-analysis.Methods We conducted a systematic review by searching four online databases (Medline, Web of Science, EMBASE and Cochrane library) of published studies that included symptoms of COVID-19 cases and severity of the disease between 01-Jan-2020 and 20-Apr-2020. PRISMA and MOOSE guidelines were followed, and only articles published in English were selected. We performed meta-analysis using Mantel-Haenszel random-effects model. Degree of heterogeneity among studies and quality of the selected studies were evaluated.Results Out of 153 articles identified, a total of seven articles, including 3,168 participants, met the inclusion criteria and were included. The median age TRANS of the patients was 49 years, 1818 (57.38%) were males TRANS, and 574 (18.11%) reported severe conditions. Fever HP Fever MESHD was the most commonly reported symptom in the reported COVID-19 confirmed cases TRANS (87.89%, 95% CI: 83.22–81.39%), which was followed by cough HP, myalgia HP myalgia MESHD or fatigue HP fatigue MESHD, and less proportionally dyspnea HP dyspnea MESHD and headache HP headache MESHD. Dyspnea HP Dyspnea MESHD was the only symptom, which was associated with severity of COVID-19 (OR 2.38, 95% CI: 1.83–3.10).Conclusions Dyspnoea MESHD was found to be associated with severity of COVID-19. People with existing respiratory illnesses, such as chronic obstructive pulmonary diseases HP chronic obstructive pulmonary diseases MESHD need to be careful about the onset of such symptom TRANS and should seek medical attention.

    Objectives:To describe a cohort of self-isolating healthcare workers (HCWs) with presumed COVID-19. Design: A cross-sectional, single-centre study. Setting: A large, teaching hospital based in Central London with tertiary infection services. Participants: 236 HCWs completed a survey distributed by internal staff email bulletin. 167 were female TRANS and 65 male TRANS. Measures: Information on symptomatology, exposures and health-seeking behaviour were collected from participants by self-report. Results: The 236 respondents reported illness compatible with COVID-19 and there was an increase in illness reporting during March 2020. Diagnostic swabs were not routinely performed. Cough HP (n=179, 75.8%), fever HP fever MESHD (n=138, 58.5%), breathlessness (n=84, 35.6%) were reported. Anosmia HP Anosmia MESHD was reported in 42.2%. Fever HP Fever MESHD generally settled within 1 week (n=110, 88%). Several respondents remained at home and did not seek formal medical attention despite reporting severe breathlessness MESHD and measuring hypoxia MESHD (n=5/9, 55.6%). 2 patients required hospital admission but recovered following oxygen therapy. 84 respondents (41.2%) required greater than the obligated 7 days off work and 9 required greater than 3 weeks off. Conclusion: There was a significant increase in staff reporting illness compatible with possible COVID-19 during March 2020. Conclusions cannot be drawn about exact numbers of confirmed cases TRANS due to lack of diagnostic swabbing. There were significant numbers of respondents reporting anosmia HP anosmia MESHD; as well as early non-specific illness prior to onset of cough HP cough MESHD and fever HP. This may represent pre-symptomatic HCWs who are likely to be infectious and thus criteria for isolation and swabbing should be broadened. The study also revealed concerning lack of healthcare seeking in respondents with significant red flag symptoms (severe breathlessness, hypoxia MESHD). This should be addressed urgently to reduce risk of severe disease being detected late. Finally, this study should inform trusts that HCWs may require longer than 7 days off work to recover from illness.

    Background: The coronavirus disease MESHD 2019 (COVID-19) caused by SARS-CoV-2 isspreading all over the world.The main symptoms of COVID-19 include fever HP fever MESHD, cough HP cough MESHD, fatigue HP, and myalgia HP myalgia MESHD. However, there are few reports onolfactoryand gustatory dysfunctions MESHD in patients with COVID-19.Objective: To investigate the incidence of olfactory and gustatory dysfunctions MESHD in patients with confirmed COVID-19 infection MESHD, in Wuhan, China.Methods:In this retrospective study,we collected 81 confirmed cases TRANS of COVID-19 from the Renmin Hospital of Wuhan University, from February 2020 to March 2020, and analyzed the demographic characteristics, clinical manifestations (including olfactory and  gustatory dysfunctions MESHD), laboratory findings,and comorbidities.Results: A total of 81 confirmed COVID-19 patients were enrolledin this study (38 males TRANS). The most prevalent symptoms include cough HP cough MESHD, myalgia HP myalgia MESHD, and loss of appetite. On admission, 25 (30.9%) of all patients reported either olfactory dysfunction MESHD ( OD MESHD) or gustatory dysfunction MESHD ( GD MESHD), and 7 (8.6%) reported both OD MESHD and GD MESHD. 13.6% and 25.9% of allpatients reported OD MESHD and GD MESHD, respectively. OD MESHD and GD MESHD were not associated with disease severity. Pearson correlation analysisidentified some factors are positively correlated with OD MESHD and GD MESHD, including headache HP headache MESHD or dizziness (r = 0.342, P = 0.002), dark urine HP (r = 0.256, P = 0.021), IgM titer (r = 0.305, P = 0.01), and diabetes MESHD (r = 0.275, P = 0.013). In 81.8% of the cases with OD MESHD and 28.6% of the cases with GD MESHD, the symptomslasted for at least 1 month after discharge.3.6% of inpatients without OD MESHD developed OD MESHD after discharge.Conclusion: OD MESHD and GDare common in COVID-19.These symptoms appear early during thecourse of disease, and may last for at least 1 month.The incidence of OD MESHD and GDisrelated to neurological manifestations, diabetics MESHD, and IgM titers.
