    Background To investigate the clinical symptoms of coronavirus disease MESHD 2019 (COVID-19), particularly the prevalence SERO, time of symptom onset TRANS, and duration of gastrointestinal ( GI MESHD) symptoms.Methods This was a cross-sectional study using paper questionnaires. COVID-19 patients in a temporary hospital in Wuhan voluntarily completed surveys collecting data on COVID-19 symptoms and investigation results.Results A total of 212 adults TRANS were enrolled in this study, of whom 127 (59.9%) were female TRANS, mean age TRANS was 48.50 ± 13.15 years. Concerning symptoms, 78.8% (167/212) had fever HP fever MESHD, and 66% (140/212) had cough HP. Diarrhoea MESHD occurred in 43.8% (93/212) of patients. Nausea and vomiting HP Nausea and vomiting MESHD vomiting MESHD were also common (20.7%). Fever HP Fever MESHD and cough HP cough MESHD were frequently the initial symptoms of COVID-19, and they lasted for 5.00 [interquartile range (IQR): 3.00–10.00] days and 10.00 (IQR: 5.00–24.00) days, respectively. Most patients developed nausea and vomiting HP nausea and vomiting MESHD vomiting MESHD 2.00 (IQR: 0–9.00) days and diarrhoea MESHD 5.00 (IQR: 0.25–11.00) days after the onset of initial symptoms, respectively. There was a median duration of 4.00 (IQR: 2.00–8.75) days with diarrhoea MESHD, and 6.00 (IQR: 4.00–10.00) days with nausea and vomiting HP nausea and vomiting MESHD vomiting MESHD. The patients with diarrhoea MESHD were younger [45.85 ± 13.28 years vs 50.61 ± 12.82 years, P = 0.009] and were more likely to have an abnormal chest CT (95.7% vs 82.4%, P = 0.001) than those without diarrhoea MESHD.Conclusions In our cohort of patients, GI symptoms MESHD were common in COVID-19, occurred mostly during the middle stage of the disease, and lasted for a short duration. GI MESHD symptoms may not be associated with COVID-19 related treatment.

    BackgroundAn ongoing outbreak of novel coronavirus disease MESHD 2019 (COVID-19) from Wuhan, China, is currently recognized as a global public health emergency, which has subsequently spread to the rest of China and other countries. The WHO raised the COVID-19 alert to the highest level. The virus is a new highly contagious via human-to-human transmission TRANS. The median duration of viral shedding is 20.0 days. We report that the longest duration of viral shedding was 32.0 days from illness onset in a patient with moderate COVID-19 admitted to QianJiang Central Hospital.Case presentationA 37-year-old male TRANS sought medical advice while suffering from fever HP fever MESHD, dry cough MESHD cough HP, fatigue HP fatigue MESHD, dizziness MESHD, runny nose and diarrhoea MESHD. Five days before the visit, he had a history of travel TRANS from affected geographic areas. The patient had a positive RT-PCR test, and chest CT images showed multiple nodules and mixed ground-glass opacification with consolidation in both lungs. Laboratory findings showed that his lymphocyte and CD4+ counts were below the normal range. The patient was given antiviral treatment, including arbidol, lopinavir, IFN-α, and traditional Chinese medicine, and other necessary support care. All clinical symptoms and CT imaging manifestation abnormalities resolved during the course of therapy.ConclusionAlthough the positive RT-PCR tests were verified in consecutive upper respiratory specimens, the clinical symptoms, CT imaging findings, CD4 + lymphocyte counts, and IgG antibody SERO levels had obviously improved. Positive tests may be detecting pieces of inactive viruses, which would not be transmissible in individual cases.

    Coronavirus disease (COVID-19) is a new discovered strain where WHO officially declares the disease as COVID-19 while the virus responsible for it called Severe Acute Respiratory Syndrome Coronavirus 2 MESHD or SARS-CoV-2. The incubation period TRANS of this disease is between 14 days. Ordinary clinical symptoms that reported around the world include fever HP fever MESHD, cough HP cough MESHD, fatigue HP fatigue MESHD, diarrhoea MESHD and vomiting HP vomiting MESHD as well as asymptomatic TRANS for certain people. Infection is spread mainly through broad droplets. In early March 2020, WHO again has announced that COVID-19 is a pandemic with currently no specific treatment. The potential use of SARS-COV-2 proteome as a vaccine candidate by analysing through B-cell and T-cell antigenicity by using a immunoinformatics approach as a vaccine development early stage. In this study, we used consensus sequence for SARS-COV-2 proteome that was retrieved from NCBI database. VaxiJen 2.0 was mainly used to identify the antigenic property of SARS-COV-2 proteins. IEDB then used to analyse the B-cell epitope, the presence of T cell immunogenic epitope in SARS-COV-2 proteins was obtained by using compromise method of MHC class I and II tools that accessible respectively using ProPred-1 server and MHC II Binding Prediction in IEDB database. The best epitopes of B and T-cell epitopes were predicted with high antigencity and the information is disseminated through web-based database resource (https://covid-19.omicstutorials.com/epitopes/). This study will be useful to find a new epitope-based candidate for SARS-COV-2. However, further study needs to be done for the next stages of vaccine development.

    This study aimed to summarize the existing literature on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection MESHD in newborns to clarify the clinical features and outcomes of neonates with COVID-19. A systematic search was performed in PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP databases from January 1, 2019 to April 30, 2020. The references of relevant studies were also searched. A descriptive summary was organized by aspects of clinical presentations (symptoms, laboratory examinations, and imaging) and outcomes. We identified 14 studies reporting 18 newborns with COVID-19. The most common clinical manifestations were fever HP fever MESHD (62.5%), shortness of breath MESHD (50.0%), diarrhea HP diarrhea MESHD/ vomiting HP vomiting MESHD/feeding intolerance(43.8%), cough HP (37.5%), dyspnea HP dyspnea MESHD (25.0%), and nasal congestion/runny nose/ sneeze HP(25.0%). Atypical symptoms included jaundice HP jaundice MESHD and convulsion MESHD. Lymphocyte numbers decreased in 5 cases, and radiographic findings were likely to show pneumonia HP pneumonia MESHD. All newborns recovered and discharged from the hospital, and there was no death.Conclusion: Clinical symptoms of neonatal SARS-CoV-2 infection MESHD are atypical, most of them are mild. Up to now, the prognosis of newborns is good, and there is no death. Intrauterine vertical transmission TRANS is possible, but confirmed evidence is still lacking. The Long-term follow-up of potential influences of SARS-CoV-2 infection MESHD on neonates need further exploration.

    The transcriptional response in Vero cells (ATCC(R) CCL-81) infected with the coronavirus Porcine Epidemic Diarrhea Virus MESHD Diarrhea HP Virus (PEDV) was measured by RNAseq analysis 4 and 6 hours after infection MESHD. Differential expressed genes (DEGs) in PEDV infected cells were compared to DEGs responding in Vero cells infected with Mammalian Orthoreovirus (MRV). Functional analysis of MRV and PEDV DEGs showed that MRV increased the expression level of several cytokines and chemokines (e.g. IL6, CXCL10, IL1A, CXCL8 [alias IL8]) and antiviral genes (e.g. IFI44, IFIT1, MX1, OASL), whereas for PEDV no enhanced expression was observed for these "hallmark" antiviral and immune effector genes. Pathway and Gene Ontology "enrichment analysis" revealed that PEDV infection MESHD did not stimulate expression of genes able to activate an acquired immune response, whereas MRV did so within 6h. Instead, PEDV down-regulated the expression of a set of zinc finger proteins with putative antiviral activity and enhanced the expression of the transmembrane serine protease gene TMPRSS13 (alias MSPL) to support its own infection by virus-cell membrane fusion (Shi et al, 2017, Viruses, 9(5):114). PEDV also down-regulated expression of Ectodysplasin A, a cytokine of the TNF-family able to activate the canonical NFKB-pathway responsible for transcription of inflammatory genes like IL1B, TNF, CXCL8 and PTGS2. The only 2 cytokine genes found up-regulated by PEDV were Cardiotrophin-1, an IL6-type cytokine with pleiotropic functions on different tissues and types of cells, and Endothelin 2, a neuroactive peptide with vasoconstrictive properties. Furthermore, by comprehensive datamining in biological and chemical databases and consulting related literature we identified sets of PEDV-response genes with potential to influence i) the metabolism of biogenic amines (e.g. histamine), ii) the formation of cilia and "synaptic clefts" between cells, iii) epithelial mucus production, iv) platelets activation, and v) physiological processes in the body regulated by androgenic hormones (like blood SERO pressure, salt/water balance and energy homeostasis). The information in this study describing a "very early" response of epithelial cells to an infection MESHD with a coronavirus may provide pharmacologists, immunological and medical specialists additional insights in the underlying mechanisms of coronavirus associated severe clinical symptoms including those induced by SARS-CoV-2. This may help them to fine-tune therapeutic treatments and apply specific approved drugs to treat COVID-19 patients.

    Background Since December 2019, there has be an outbreak of coronavirus disease MESHD 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) in Wuhan, China. Nowadays, it rapidly spread across the country and then the worldwide. We aimed to investigate the clinical characteristics of patients with COVID-19.Methods The patients with confirmed COVID-19 admitted between January 25 and February 10, 2020, were enrolled. Epidemiological, demographic, clinical, laboratory, radiological data, and antivirus therapies, were retrospectively collected and analyzed. The 90-day follow-up of these patients was also performed.Results A total of 107 patients were included. The median age TRANS was 55.0 years (range from 18.0 to 85.0 years), and 72 (67.3%) were female TRANS. Ninety-three (86.9%) of the patients had a history of contacting with residents from Wuhan (n=31), or contacting with confirmed COVID-19 patients (n=62) within 2 weeks. Fifty-eight (54.2%) had a family cluster onset. Fever HP Fever MESHD and cough HP cough MESHD were the most common symptoms. Only two patients had diarrhea HP diarrhea MESHD. The most common underlying disease was hypertension HP hypertension MESHD. Lymphopenia HP Lymphopenia MESHD was observed in 26 patients. Fifty-two patients with an elevated level of IL-6. On admission, bilateral patchy shadowing and ground-glass opacity were the typical radiological findings on chest computed tomography. Six patients had an intensive care unit (ICU) stay. Antivirus therapy was performed to all patients. 105 patients discharged with an improved condition, and no death MESHD was occurred during our 90-day follow-up for these patients.Conclusions Patients with COVID-19 in our hospital had relatively mild symptoms, and good prognosis. This study also highlights the importance of human-to-human transmission TRANS in COVID-19.

    Background: SARS-CoV-2 is highly infectious and has been a significant public health threat. Despite typical manifestations of illness are dominated by respiratory symptom, some patients have concurrent gastrointestinal manifestations, including   nausea MESHD, diarrhea HP diarrhea MESHD, and vomiting HP vomiting MESHD. Massive gastrointestinal bleeding MESHD, however, has rarely been reported. Case presentation: We herein describe a case of severe SARS-CoV-2 infected MESHD patient with several risk factors for poor prognosis, including male TRANS, hypertension HP hypertension MESHD, old age TRANS, mixed bacterial infection MESHD and multilobular infiltration on radiological imaging. After improvement of respiratory status, the onset of gastrointestinal bleeding MESHD occurred, probably resulting from direct viral invasion as evidenced by the positive findings for SARS-CoV-2 in the repeat stool specimens. Although aggressive resuscitation was administered, hematochezia HP hematochezia MESHD was uncontrolled. The patient rapidly deteriorated, suffered cardiac arrest HP cardiac arrest MESHD, and expired. Conclusions: Digestive symptoms could be severe in SARS-CoV-2 infected MESHD patients, especially for the high-risk individuals with predisposing conditions. A more thorough protocol for preventing cross-infection MESHD through faecal-oral transmission TRANS should be implemented in the process of patient care and infection MESHD control.

    Background coronavirus disease-19 (COVID-19) has spread to several countries around the world and has become an unprecedented pandemic. We report an extremely rare case of acute acalculous cholecystitis MESHD cholecystitis HP on a COVID-19 patient. In our knowledge, this is the first report of laparoscopic cholecystectomy performed on a COVID-19 patient.Case presentation: a COVID-19 patient was diagnosed with acute acalculous cholecystitis MESHD cholecystitis HP and a multidisciplinary team decided to perform a percutaneous transhepatic biliary drainage (PTBD) as the first treatment. SARS-CoV-2 RNA was not found in the bile fluid. Because of deterioration of the patient’s clinical conditions, laparoscopic cholecystectomy had to be performed and since the gallbladder was gangrenous MESHD, the severe inflammation MESHD made surgery difficult to perform.Conclusions acalculous cholecystitis MESHD cholecystitis HP was related with mechanical ventilation and prolonged total parenteral nutrition, in this case the gangrenous MESHD histopathology pattern and the gallbladder wall ischemia MESHD was probably caused by vascular insufficiency MESHD secondary to severe acute respiratory distress syndrome MESHD respiratory distress HP syndrome of COVID-19 pneumonia MESHD pneumonia HP. The percutaneous transhepatic gallbladder drainage (PTBD) was performed according to Tokyo Guidelines because of high surgical risk. Laparoscopic cholecystectomy was next performed due to no clinical improvement. The absence of viral RNA in the bile highlights that SARS-CoV-2 is not eliminated with the bile while it probably infects MESHD small intestinal enterocytes which is responsible of gastrointestinal symptoms such as anorexia HP anorexia MESHD, nausea, vomiting HP nausea, vomiting MESHD vomiting MESHD, and diarrhea HP diarrhea MESHD. Although the lack of evidence and guidelines about the management of patient with acute cholecystitis MESHD cholecystitis HP during COVID-19 pandemic, laparoscopic cholecystectomy, at most preceded by PTGBD on high surgical risk patients, remains the gold standard for the treatment of acute cholecystitis MESHD cholecystitis HP on COVID-19 patients.

    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 HP (78.0%), sputum (62.7%), and fever HP fever MESHD (59.2%). The less common symptoms were fatigue HP fatigue MESHD (29.4%), diarrhea HP diarrhea MESHD (25.9%), and dyspnea HP dyspnea MESHD (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 HP dyspnea MESHD, 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 MESHD+1.54×CRP+1.03×lymphocyte+1.03×AST+1.76×calcium). Dyspnea HP Dyspnea MESHD (OR=5.91) and hypocalcemia HP hypocalcemia MESHD (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.

    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 of the study was to identify symptoms and their frequencies of coronavirus disease MESHD 2019 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 relevant articles. Eligibility criteria: Suitable articles were selected manually with selection criteria and 14 original articles included for meta-analysis. Data abstraction analysis: PRISMA guideline was used for abstracting data. Then a table was generated by feeding it with numbers and proportions of each symptom described in original studies. 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 calculated.Results: We identified 14 relevant scientific papers, either cross-sectional or cohort studies and analyzed. There were 2,660 cases of COVID-19. he 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 (i.e. present in >50% of patients):  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% of patients) were: tonsil swelling, haemoptysis, conjunctival injection, lymphadenopathy HP lymphadenopathy MESHD and rash MESHD were uncommon symptoms of coronavirus disease MESHD (<5%).Conclusion and implications of key findings: We found (25/32) symptoms to be present in =>5% of cases which could be considered as “typical” symptoms of COVID-19. The list of symptoms we identified are 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.
