    Background: Moderate cases account for the majority in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection MESHD and can also progress to severe/critical condition. Here, we investigated the clinical course and management of hospitalized moderate SARS-CoV-2 patients.Methods: The medical records and follow-up data were analyzed from the SARS-CoV-2 patients outside Wuhan.Results: A total of 73 moderate patients (38 men, 35 women) were included, with median age TRANS of 47.0 (38.5-57.5) years. Among them, only one patient (1.4%) died using active treatment to improve symptoms. The median duration of the four main symptoms cough HP, fever HP fever MESHD, chest tightness HP chest tightness MESHD, and fatigue HP fatigue MESHD were about 1-2 weeks; the median duration of the positive nucleic acid test (NAT) results for SARS-CoV-2 was slightly more than 2 weeks; the median hospitalization time was almost four weeks in 72 moderate survivors. The duration of cough HP cough MESHD and fever HP fever MESHD was positively correlated with the duration of the positive NAT results. On admission, 50% had lymphopenia HP lymphopenia MESHD; less than 30% had abnormal blood SERO biochemistry findings involving hyperglycemia HP hyperglycemia MESHD, liver function and myocardial enzymes. At discharge, the laboratory indexes were substantially improved. Two weeks after discharge, 5.6% survivors experienced a recurrence of the positive NAT results. Conclusions: Moderate SARS-CoV-2 patients have a good prognosis by the active treatment. After discharge, it is necessary that moderate survivors undergo at least a 2-week collective medical observation in quarantine places, which can identify and treat a proportion of patients with re-positive NAT results and to prevent the spread of the potential sources of infection MESHD.

    Background: The Coronavirus Disease MESHD 2019 (COVID-19) already have been as a pandemic. However, knowledge about the sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection MESHD remains limited. Here we descirbe the pulmonary function test (PFT) and cardiopulmonary exercise test (CPET) of critically ill COVID-19 in four cases with sereve acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD) after discharge.Case presentation: We introduce four patients who complained of fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD and other symptoms, all of them were confirmed as SARS-CoV-2 infection MESHD by real-time reverse transcription polymerase chain reaction (RT-PCR). They were treated with mechanical ventilation because of severe ARDS MESHD. After respiratory support, antiviral and anti-infective treatment, they were weaned from mechanic ventilation with the improvement of hypoxemia HP hypoxemia MESHD. All patients were discharged from the hospital after completion of treatment and had no mortality. Around 1-month post-discharge, they were followed up for chest computed tomography (CT) scan, and performed PFT and CPET. Peak oxygen uptake of predicted (peakVO2% pred) decreased in all four cases, although spirometry were in the normal range, and only 2 cases had mild decline in carbon monoxide diffusion capacity of predicted (DLCO%pred).Conclusions: We found reduced exercise endurance in all four COVID-19 survivors, even parts of them with normal or slightly abnormal static lung function. We also believe that exercise endurance impairment of COVID-19 convalescents is more likely affected by extrapulmonary factors. Taken the above into consideration, our study highlights that the combination of PFT and CPET are important tests for tracking the development and recovery of COVID-19 survivors.

    Background Coronavirus Disease MESHD 2019 (COVID-19) is a rapidly expanding global pandemic resulting in significant morbidity and mortality. COVID-19 patients may present with acute myocardial infarction MESHD myocardial infarction HP ( AMI MESHD). The aim of this study is to conduct detailed analysis on patients with AMI MESHD and COVID-19. Methods We included all patients admitted with AMI MESHD and actively known or found to be COVID-19 positive by PCR between the 4th February 2020 and the 11th June 2020 in the State of Qatar. Patients were divided into ST-elevation myocardial infarction HP myocardial infarction MESHD (STEMI) and Non-STE (NSTEMI). Results There were 68 patients (67 men and 1 woman) admitted between the 4th of February 2020 and the 11th of June 2020 with AMI MESHD and COVID-19. The mean age TRANS was 49.1, 46 patients had STEMI and 22 had NSTEMI. 38% had diabetes mellitus HP diabetes mellitus MESHD, 31% had hypertension HP hypertension MESHD, 16% were smokers, 13% had dyslipidemia MESHD, and 14.7% had prior cardiovascular disease MESHD. Chest pain HP Chest pain MESHD and dyspnea HP dyspnea MESHD were the presenting symptoms in 90% and 12% of patients respectively. Fever HP Fever MESHD (15%) and cough HP cough MESHD (15%) were the most common COVID-19 symptoms, while the majority had no viral symptoms. Thirty-nine (33 STEMI and 6 NSTEMI) patients underwent coronary angiography, 38 of them had significant coronary disease MESHD. Overall in-hospital MACE was low; 1 patient developed stroke HP stroke MESHD and 2 died. Conclusion Contrary to previous small reports, overall in-hospital adverse events were low in this largest cohort of COVID-19 patients presenting with AMI MESHD. We hypothesize patient profile including younger age TRANS contributed to these findings. Further studies are required to confirm this observation.

    Currently, the COVID‐19 has directly affected the millions of humans lives. The symptoms of the disease involving fever HP fever MESHD, malaise MESHD, chest infection MESHD, and breathing difficulties MESHD, were identified, and its existence is continuously becoming restructured. The World Health Organization (WHO) had mentioned the wide diagnostics test besides COVID-19 that would also assist medical facilities to recognize infectious diseases MESHD as well as currently focusing efficiently on preventing and afterward defeating this viral disease. The infection is usually transmitted among human beings in direct contact, greatest through the liquid bubbles generated through cough HP, sneeze HP, or speaking. This paper reviews the COVID 19 pandemic, its history, current updates, contact tracing TRANS applications, and use of emerging technologies like the Internet of Things (IoT) and Blockchain for stopping the spreading and provide service online to the patient from a distance.

    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.

    Background: In March 2020, the WHO declared the novel coronavirus (COVID-19) outbreak a global pandemic. While great success in the coronavirus disease MESHD 2019 (COVID-19) control has been achieved in China, imported cases have become a major challenge. This study aimed to describe the epidemiological and clinical characteristics of imported COVID-19 cases and to assess the effectiveness of screening strategy in Beijing, China.Methods: This retrospective study included all imported COVID-19 cases from Beijing Ditan Hospital from 29 February to 20 March 2020, who were screened by both chest MESHD computed tomography (CT) and reverse-transcriptase-polymerase chain reaction (RT-PCR) at initial presentation. Demographic, clinical and laboratory data, in addition to chest CT imaging were collected and analyzed. Results: A total of 71 imported cases were finally diagnosed with laboratory-confirmed COVID-19. The cases were mainly acquired from Europe (63cases, 88.73%). The main clinical manifestations were fever HP fever MESHD and cough HP cough MESHD, which accounted for 30 cases (42.25%) and 35 cases (49.30%), respectively. Only 4 cases (5.63%) had lymphocytopenia MESHD and 13 (18.31%) cases demonstrated elevated levels of C-reactive protein HP (CRP). All cases had normal serum SERO levels of procalcitonin(PCT). 35 cases (49.30%) had abnormal CT findings at initial presentation, whereas 36 cases (50.70%) had a normal CT. Using RT-PCR, 59 cases (83.10%) were tested positive at initial presentation.Conclusions: The combination of screening tools, particularly CT and RT-PCR, could be considered to improve the diagnosis in imported COVID-19 cases. Our findings provide the important information and clinical evidence for infection control of imported COVID-19 cases.

    A novel form of coronavirus disease MESHD (SARS-CoV-2) has spread rapidly across the world. This disease, originating in Wuhan, China, has become a global pandemic. What risk factors influence the severity of the disease is of considerable importance. This research is intended to offer a systematic review/meta-analysis for assessing how common clinical conditions and comorbidities correlate with COVID-19. The meta-analysis incorporated seven studies covering 4101 COVID-19 patients from Chinese hospitals who had their diagnosis confirmed through laboratory testing. The findings demonstrate that the most common comorbidities with the disease were COPD MESHD (2.53%, OR 3.24 [95% CI: 1.99-4.45], p< 0.0006), cardiovascular disease MESHD (10.76%, OR 2.89 [95% CI: 1.90-4.40], p <0.0001), coronary heart disease MESHD (5.52%, OR 2.97 [95% CI: 1.99-4.45], p <0.0001), diabetes MESHD (11.34%, OR 2.27, [95% CI: 1.46-3.53], p = 0.0003), and hypertension HP hypertension MESHD (22.07%, OR 2.43 [95% CI: 1.71-3.45], p <0.0001). No significant associations were found for disease severity with the comorbidities of kidney disease MESHD, liver disease MESHD, or cancer MESHD. The most frequently exhibited clinical symptoms were fever HP fever MESHD (74.52%, OR 1.37, 95% CI: 1.01-1.86, p = 0.04), cough HP (62.15%, OR 1.25, 95% CI: 0.97-1.60, p = 0.0823), myalgia HP myalgia MESHD/ fatigue HP fatigue MESHD (38.77%, OR 1.31, 95% CI: 1.11-1.55, p = 0.0018), dyspnea HP dyspnea MESHD (33.9%, OR 3.61, 95% CI: 2.57-5.06, p = <0.0001), respiratory failure HP respiratory failure MESHD/ARDS (20.6%, OR 11.46, 95% CI: 3.24-40.56, p = 0.0002), diarrhea HP diarrhea MESHD (11.21%) and chest tightness HP chest tightness MESHD/ pain HP (16.82%, OR 2.17, 95% CI: 1.40-3.36, p = 0.0006). Meta-analysis also revealed that neither the duration of the incubation period TRANS nor current smoking status associated with disease severity.

    Background: A novel form of coronavirus disease MESHD (SARS-CoV-2) has spread rapidly across the world. What risk factors influence the severity of the disease is of considerable importance.Aim: This research offers a systematic review and meta-analysis of the correlation between common clinical conditions and comorbidities and the severity of COVID-19.Methodology: Two independent researchers searched Europe PMC, Google Scholar, and PubMed databases for articles related to influence comorbidities have on the progress of the disease. A search engine was also created to screen a further 59,000 articles in COVID-19 Open Research Dataset (CORD-19). Random-effects modeling was used to pool 95% confidence intervals (CIs) and odds ratios (ORs). The significance of all comorbidities and clinical conditions to the severity of the disease was evaluated by employing machine-learning techniques. Publication bias was assessed by using funnel-plots and Egger’s test. Heterogeneity was tested using I2.Results: The meta-analysis incorporated 12 studies spanning 4,101 confirmed COVID-19 patients who were admitted to Chinese hospitals. The prevalence SERO of the most commonly associated co-morbidities and their corresponding odds ratio for disease severity were as follows: coronary heart disease MESHD (OR 2.97 [CI: 1.99-4.45], p < 0.0001), cancer MESHD (OR 2.65 [CI: 1.12-6.29], p < 0.03), cardiovascular disease MESHD (OR 2.89 [CI: 1.90-4.40], p < 0.0001), COPD MESHD (OR 3.24 [CI: 1.66-6.32], p = 0.0), and kidney disease MESHD (OR 2.2.4 [CI: 1.01-4.99], p = 0.05) with low or moderate level of heterogeneity. The most frequently exhibited clinical symptoms were fever HP fever MESHD (OR 1.37 [CI: 1.01-1.86], p = 0.04), myalgia HP myalgia MESHD/ fatigue HP fatigue MESHD (OR 1.31 [CI: 1.11-1.55], p = 0.0018), and dyspnea HP dyspnea MESHD (OR 3.61, [CI: 2.57-5.06], p = <0.0001). No significant associations between disease severity and liver disease MESHD, smoking habits, and other clinical conditions, such as a cough HP, respiratory/ARDS, diarrhea HP diarrhea MESHD or chest tightness HP chest tightness MESHD/ pain HP pain MESHD were found. The meta-analysis also revealed that the incubation period TRANS was positively associated with disease severity. Conclusion: Existing comorbidities, including COPD, cardiovascular disease MESHD, and coronary heart disease MESHD, increase the severity of COVID-19. Some studies found a statistically significant association between comorbidities such as diabetes MESHD and hypertension HP hypertension MESHD and disease severity. However, these studies may be biased due to substantial heterogeneity.
