    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

    Introduction: COVID-19 affected worldwide, causing to date, around 500,000 deaths. In Mexico, by April 29, the general case fatality was 6.52%, with 11.1% confirmed case TRANS mortality and hospital recovery rate around 72%. Once hospitalized, the odds for recovery and hospital death rates depend mainly on the patients' comorbidities and age TRANS. In Mexico, triage guidelines use algorithms and risk estimation tools for severity assessment and decision-making. The study's objective is to analyze the underlying conditions of patients hospitalized for COVID-19 in Mexico concerning four severity outcomes. Materials and Methods: Retrospective cohort based on registries of all laboratory-confirmed patients with the COVID-19 infection MESHD that required hospitalization in Mexico. Independent variables were comorbidities and clinical manifestations. Dependent variables were four possible severity outcomes: (a) pneumonia HP pneumonia MESHD, (b) mechanical ventilation (c) intensive care unit, and (d) death; all of them were coded as binary Results: We included 69,334 hospitalizations of laboratory-confirmed and hospitalized patients to June 30, 2020. Patients were 55.29 years, and 62.61% were male TRANS. Hospital mortality among patients aged TRANS<15 was 9.11%, 51.99% of those aged TRANS >65 died. Male TRANS gender TRANS and increasing age TRANS predicted every severity outcome. Diabetes MESHD and hypertension HP hypertension MESHD predicted every severity outcome significantly. Obesity HP did not predict mortality, but CKD, respiratory diseases MESHD, cardiopathies were significant predictors. Conclusion: Obesity HP increased the risk for pneumonia HP pneumonia MESHD, mechanical ventilation, and intensive care admittance, but it was not a predictor of in-hospital death. Patients with respiratory diseases MESHD were less prone to develop pneumonia HP pneumonia MESHD, to receive mechanical ventilation and intensive care unit assistance, but they were at higher risk of in-hospital death.

    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: 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.

    Background: Clinical spectrum of COVID-19 has been unclear, especially with regard to the presence of pneumonia HP pneumonia MESHD. We aimed to present clinical course of all laboratory-confirmed adult TRANS COVID-19 patients and to identify potential predicting factors of pneumonia HP pneumonia MESHD. Methods: We conducted a retrospective study among adult TRANS patients with confirmed COVID-19 who were hospitalized at Bamrasnaradura Infectious Diseases Institute, Thailand, regardless of their disease severity, between January 8 and April 16, 2020. We described the full picture of COVID-19, defined definite outcomes and evaluated factors associated with pneumonia HP pneumonia MESHD. Results: One-hundred-and-ninety-three patients were included. The median (IQR) age TRANS was 37.0 (29.0-53.0) years, and 58.5% were male TRANS. Of whom, 189 (97.9%) recovered and 4 (2.1%) died. More than half (56%) of the patients were mild, 22% were moderate, 14% were severe, and 3% were critically ill. Asymptomatic TRANS infection MESHD was found in 5%. The overall incidence of pneumonia HP pneumonia MESHD was 39%. Bilateral was more prevalent than unilateral pneumonia MESHD pneumonia HP (65% vs. 35%). Increasing age TRANS (OR 2.60 for every 10-year increase from 30 years old; 95% CI, 1.68 to 3.97; p<0.001), obesity HP obesity MESHD (OR 9.17; 95% CI, 2.11 to 39.89; p=0.003), and higher temperature at presentation (OR 4.66 per one-degree Celsius increase from 37.2 degree Celsius; 95% CI, 2.32 to 9.34; p<0.001) were potential predicting factors of COVID-19 pneumonia HP pneumonia MESHD. Severe cases had a longer viral RNA shedding duration than the non-severe cases. The longest observed duration of viral RNA shedding was 45 days. Conclusion: Across different disease severities, most patients with COVID-19 in Thailand had a good prognosis. COVID-19 pneumonia HP pneumonia MESHD was found in one-third of the hospitalized patients. Potential predicting factors included old age TRANS, obesity HP obesity MESHD, fever HP fever MESHD at presentation.

    Introduction: Severe Novel Coronavirus Disease MESHD 2019 (COVID-19) infection MESHD in neonates is possible but reports are scarce.  Lung ultrasound (LUS) has been reported useful for triaging, diagnosing, and monitoring of patients with COVID-19.Material and methods: We describe SARS-CoV-2 confirmed infection MESHD confirmed infection TRANS on a term newborn that developed pneumonia HP pneumonia MESHD and pulmonary hypertension MESHD hypertension HP requiring mechanical ventilation. Ultrasonographic follow up of COVID-19 pneumonia HP pneumonia MESHD and pulmonary hypertension MESHD hypertension HP was carried out. Histopathological and genetic study of the placenta was performed. Results: A 3,140-g male TRANS infant born at 40.3 weeks’ gestation developed progressive respiratory distress HP respiratory distress MESHD ( pulmonary hypertension MESHD hypertension HP) requiring mechanical ventilation. Real time PCR respiratory tract swabs for SARS COV 2 sampled on day 3 were positive for the baby and both parents TRANS. Lung ultrasound showed an irregular pleural MESHD line (shred sign), multiple confluent B-lines and bilateral ≥ 0.5 cm subpleural consolidations. Improvement of the lung and cardiac conditions were documented by ultrasound. The newborn was supported 6 days with mechanical ventilation, 3 days on CPAP and 3 days on oxygen. No antibiotics were used. The placenta showed histological findings linked to SARS-CoV-2 infection MESHD. RT-PCR from placental tissue showed amplification of viral E gene.Conclusion: Our case represents a severe presentation of COVID-19 pneumonia HP pneumonia MESHD with pulmonary hypertension MESHD hypertension HP requiring mechanical ventilation. LUS showed to be useful for diagnosis and follow up.

    Background: Coronavirus Disease MESHD 2019 (Covid-19) pandemic since its first confirmed case TRANS, has changed the world. The need for accurate and truthful information is vital. Mexico and Latin America have been widely affected, so having local epidemiological data, will be of great clinical utility. Methods: A total of 33 hospitalized patients with Covid-19 pneumonia HP pneumonia MESHD (either severe or critical) were identified from electronic health record in a third level care private hospital in Mexico City from March 13rd to April 13rd, 2020. We conducted a descriptive study of patients for characterization of the clinical, laboratory and radiologic findings, as well as complications. Results: The mean age TRANS was 60.6 (12.68) years and 23 (69.7%) were males TRANS. Twenty-three patients (69.6%) were overweight HP or obese MESHD. The median duration of symptoms before admission was 7 days. All the patients required mechanical invasive ventilation. The median duration of the mechanical ventilation was 12(2.6) days and all patients were extubated except one. All patients were started on antiviral treatment in the first 24 hours after admission once the diagnosis of Covid19 pneumonia HP pneumonia MESHD was made. There was no difference between the treatment option and the length of stay. The extubation rate was higher (91.6%) than in other series, with no fatalities even though they were treated with different regimens. Conclusions: This one-centre experience describes the epidemiology, treatment and outcome of 33 patients with severe or critical COVID pneumonia MESHD pneumonia HP admitted to the ICU. Most patients in our series were overweight HP or obese MESHD male TRANS, which we observed were of higher risk to present critical pneumonia HP pneumonia MESHD, as well as high levels of Interleukin-6. The foregoing is relevant, due to the high incidence of these comorbidities in our country.

    Background: To investigate the epidemiological features of coronavirus disease MESHD 2019(COVID-19) and the prevention measures in Jiangsu Province. Methods: Information of all novel coronavirus pneumonia HP confirmed cases TRANS in Jiangsu was collected from the official website of Jiangsu Commission of Health. All data were entered into Excel and Python3 for statistical analysis. Epidemiological characteristics of novel coronavirus pneumonia HP confirmed cases TRANS from January 10, 2020 to March 18 in Jiangsu province were retrospectively analyzed. Meanwhile, the preventive measures of Jiangsu Commission of Health and the people’s Government of Jiangsu Province were also analyzed. Results: 631 COVID-19 cases were diagnosed in Jiangsu Province, covering 13 cities in Jiangsu. Before February 1, the confirmed cases TRANS were mainly imported cases, and after February 1, community transmission TRANS cases became main part of confirmed cases TRANS. There were more male TRANS patients than females TRANS, and most patients were in the group of 30-70 years old, 49 patients (7.8%) with mild symptom and 572 patients (90.6%) with common type accounted for the majority. The cumulative mortality rate was 0% and the cure rate was 100%. Reasonable treatments, timely and effective preventive measures were taken to effectively improve cure rate and to prevent the spread of the epidemic, all measures ensure the health and life safety of the people. Conclusion: The preventive measures in Jiangsu Province were timely and effective, the epidemic situation in Jiangsu Province had been well controlled.

    Background: Severe acute respiratory syndrome MESHD coronaviruses -2 (SARS-COV2) named as COVID-19 had spread worldwide and leading to 1,210,956 confirmed cases TRANS and 67,594 deaths Methods: A data of 1192 confirmed cases TRANS and 43 deaths due to COVID-19 in Japan collected from the Ministry of Health, Labour and Welfare of Japan and analysed for different epidemiological parameters and their clinical manifestations. We used Clauset-Newman-Moore (CNM) clustering algorithm to develop web-network of confirmed cases TRANS to identified clusters of community transmission TRANS. Results: Out of 1192 confirmed cases TRANS, 90.60% were symptomatic and 9.39% were asymptomatic TRANS. The prevalence SERO of COVID19 in males TRANS was 56.29% and 43.20 % in females TRANS. The mean interval (SD) from symptom onset TRANS to diagnosis was 6-22.6 days while mean interval (SD) from contact to onset of symptoms TRANS was 5-19.5 days. People of age TRANS range 40-79 were more infected MESHD and deaths median age TRANS was 80. The main symptoms were fever HP fever MESHD, dry cough MESHD cough HP, fatigue HP fatigue MESHD and pneumonia HP pneumonia MESHD. The main infected cities were Tokyo (195/1192, 16.35%), Hokkaido (160/1192 13.42%), Aichi (150/1192, 12.58%) and Osaka (145/1192, 12.16%). Only 2.34% cases had travel TRANS history from Wuhan China and Osaka music concert was identify as main cluster for community transmission TRANS. While 556 (46.64%) cases were clinically diagnosed and 557 (46.72%) were confirmed by using RT-PCR. Conclusions: Other than, declare emergency Japan need to change their approach of diagnosing COVID-19, as asymptomatic TRANS cases prevalence SERO is high and maybe it is reason for current sudden increase of cases. Screening centre should be establish away from hospitals, which are treating positive cases.
