    A patient will visit physicians when he/she feels ill. This illness is not for COVID-19 but it is a general tendency of human being to visit doctor probably it can not be controlled by general drug. When a patient comes to a doctor, the doctor examines him/her after knowing his/her problem. The physician always asks him/her about some questions related to him/her daily life. For example, if a young male TRANS patient comes to a doctor with a symptom of fever HP fever MESHD and cough HP cough MESHD, the first question doctor asked him that he has a habit of smoking. Then doctor asks him whether this type of symptom appeared often to him previously or not. If the answers of both questions are yes, then the first one is habit and the second one is that he may suffering from some serious disease MESHD or a disease due to the weather. The aim of this paper is to consider habit of the patient as well as he/she has been affected by a critical disease. This information is used to build a model that will predict whether there is any possibility of his/her being affected by COVID-19. This research work contributes to tackle the pandemic situation occurred due to Corona Virus Infectious Disease MESHD, 2019 (Covid-19). Outbreak of this disease happens based on numerous factors such as past health records and habits of patients. Health records include diabetes tendency MESHD, cardiovascular disease MESHD existence, pregnancy, asthma HP asthma MESHD, hypertension HP hypertension MESHD, pneumonia HP pneumonia MESHD; chronic renal disease MESHD may contribute to this disease occurrence. Past lifestyles such as tobacco, alcohol consumption may be analyzed. A deep learning based framework is investigated to verify the relationship between past health records, habits of patients and covid-19 occurrence. A stacked Gated Recurrent Unit (GRU) based model is proposed in this paper that identifies whether a patient can be infected by this disease or not. The proposed predictive system is compared against existing benchmark Machine Learning classifiers such as Support Vector Machine (SVM) and Decision Tree (DT).

    ABSTRACT Background: The Coronavirus disease 2019 (covid-19) pandemic has spread rapidly across the globe. Accurate clinical characterisation studies are essential to informing research, diagnosis and clinical management efforts, particularly early in a pandemic. In this scoping review we identify the clinical characteristics of patients admitted to hospital in the early months of the pandemic, focusing on symptoms, laboratory and imaging findings, and clinical outcomes. Methods: A scoping review. MEDLINE, EMBASE and Global Health databases were searched studies published from January 1st 2020 to April 28th 2020. Studies which reported on at least 100 hospitalised patients with covid-19 of any age TRANS were included. Results: Of 1,249 studies identified through the search 78 studies were eligible for inclusion; one randomized control trial and 77 observational studies presenting data on 77,443 patients admitted with covid-19. Most studies were conducted in China (82%), 9% in the US and 10% in Europe and two studies were set in more than one country. No studies included patients from low and middle income countries. Coagulopathy MESHD was underrecognised as a complication in the early months of the pandemic. Use of corticosteroids varied widely, and the use of anticoagulants was reported in only one study. Fever HP Fever MESHD, cough HP cough MESHD and dyspnoea are less common in older adults TRANS; gastrointestinal symptoms, as the only presenting feature may be underrecognised. The most common laboratory finding was lymphocytopenia MESHD. Inflammatory biomarkers were commonly elevated, including C-reactive protein and interleukin-6. Typical computed tomography findings include bilateral infiltrates however imaging may be normal in early disease. Data on clinical characteristics in children TRANS and vulnerable populations were limited. Conclusions: Clinical characterisation studies from early in the pandemic indicated that covid-19 is a multisystem disease MESHD, with biomarkers indicating inflammation MESHD and coagulopathy MESHD. However, early data collection on symptoms and clinical outcomes did not consistently reflect this wide spectrum. Corticosteroid use varied widely, and anticoagulants were rarely used. Clinicians should remain vigilant to the possibility of covid-19 in patients presenting without fever HP fever MESHD, cough HP cough MESHD and dyspnoea, particularly in older adults TRANS. Further characterisation studies in different at-risk populations is needed.

    Background: The total mortality rate of COVID-19 is estimated almost at 2 % based on a wide range of publications. To avoid negative global impact of this new emergency, the entailment of control measures for prevention is highly recommended. Unfortunately, Iran has been the manifestation of attention as one of the countries is struggling with this pandemic. Here we intend to report a unique case of 2019-nCoV infected patient with underlying diseases MESHD and one of the rare pulmonary manifestations of 2019-nCoV infection MESHD ( pleural effusion HP pleural effusion MESHD) who has recovered and discharged. Case presentation: The current case report from Iran showed a positive COVID-19 case accompanied by pleural effusion HP pleural effusion MESHD and severe pneumonia HP pneumonia MESHD and even underlying diseases. She received twelve days of treatment and recovered with good oxygen saturation and without associated factors including fever HP fever MESHD and cough HP cough MESHD. In this report, presentations, diagnoses and management of novel 2019 coronavirus patient has been described in details. Conclusions: The pleural effusion HP pleural effusion MESHD in 2019-nCoV is not a dominant feature and can be considered as one of the diagnostic features in the disease. Even with underlying diseases, 2019-nCoV symptoms are not supposed to be severed.

    Background: Since December 2019, a severe novel coronavirus ( SARS-CoV-2) infection (Coronavirus Disease MESHD 2019,COVID-19) has occurred in Wuhan, China, and has rapidly spread to the country and around the world. This study intends to investigate the epidemiological and clinical characteristics of patients with COVID-19 in a surrounding city of Wuhan.Methods: A retrospective study was conducted on 208 cases of COVID -19 patients from February 11, 2020 to February 29, 2020 in Xiaogan dongnan Hospital, collected basic information, history of exposure, medical history, clinical symptoms, laboratory indicators and pulmonary imaging Data, and analyzed the epidemiological and clinical characteristics of all patients. According to the clinical classification criteria, 208 patients were divided into light group and ordinary group, and the epidemiological and clinical characteristics of the two groups were compared.Results: Among 208 patients in this study, with a median age TRANS of 50.5 years (IQR,36-64.7,range,10-91 years), among which 107 (51.4%) were males TRANS and 101 (48.6%) were females TRANS. 51 (24.5%) had a clear exposure to COVID-19 infection within 2 weeks before admission, and 40 (19.2%) had a history of residence or exposure in Wuhan within 2 weeks before admission. Among all the patients, there were 16 (7.7%) with pulmonary diseases MESHD, 41 (19.7%) with hypertension HP hypertension MESHD, 11 (5.3%) with coronary heart disease MESHD, 13 (6.3%) with diabetes MESHD, 12(5.8%) with a history of alcohol consumption, and 12(5.8%) with a history of smoking. Among all clinical symptoms, 146 cases (70.2%) of fever HP fever MESHD, the highest temperature range was 37.3℃-41℃ before admission, 115 (55.3%) cases of cough HP, and 57 (27.4%) cases of chest tightness HP chest tightness MESHD, 47 (22.6%) cases of fatigue HP fatigue MESHD, 28 (13.5%) cases of inappetence, 9 (4.3%) cases of diarrhea HP diarrhea MESHD, 7 (3.4%) cases of nasal congestion or runny nose , and 5 ( 2.4%) cases of pharyngalgia. Analysis of the laboratory results of 208 patients showed that 42 (20.2%) cases had decreased white blood SERO cell count, and 61 (29.3%) cases had decreased lymphocyte count. There were 154 (74%) cases with elevated CRP, 50 (24%) cases with elevated fasting blood SERO glucose, and 23 (11.1%) cases with elevated LDH (>245U/L). The comparison of clinical characteristics between the light group and the common group showed that the median age TRANS of the light group was 44.8 years (IQR 30-58), the median age TRANS of the common group was 53.1 years (IQR 38.8-67) (P<0.01). The symptoms of fever HP fever MESHD [53(80.3%) vs 93(65.5%),P<0.05], fatigue HP fatigue MESHD [53(80.3%) vs 93(65.5%),P<0.05] and inappetence [4(6.1%) vs 24(16.9%),P<0.05] in the light group were less than those in the common group. The white blood SERO cell count (5.48 vs 6.37, P<0.05), lymphocyte count (1.40 vs 1.61, P<0.05) and HDL-C (1.5 vs 1.3, P<0.05) of the common group were lower than that of the light group, while CRP (26.5 vs 22.1, P<0.01), AST (22.9 vs 18.5, P<0.05), fasting blood SERO glucose (5.8 vs 5.6, P<0.05), LDH (196.8 vs 157.9, P<0.001) of the common group were higher than that of the light group.Conclusion: COVID-19 infection is mainly in middle- aged TRANS and elderly TRANS patients, patients with other diseases MESHD are more susceptible to infection. The main symptoms of COVID-19 infection MESHD were fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD, fatigue HP fatigue MESHD, and inappetence. Decreased lymphocyte count, increased CRP concentration, increased LDH concentration and decreased HDL-C concentration were the laboratory features of COVID-19 infection MESHD, and were important indicators to assess the severity of COVID-19 disease.

    Objective: The novel coronavirus disease MESHD (COVID-19) was first reported in Wuhan, China in December 2019 and is now pandemic all over the world. Previous study has reported several COVID-19 cases with conjunctivitis HP conjunctivitis MESHD. However, the complete profiling of COVID-19 related ocular symptoms and diseases MESHD are still missing. We aim to investigate the ocular manifestations and clinical characteristics of COVID-19 patients. Methods: A total of five hundred and thirty-four patients were recruited at Mobile Cabin Hospital and Tongji Hospital. We collected information on demographic characteristics, exposure history, ocular symptoms, systemic concomitant symptoms, eye drop medication, eye protections, radiologic findings, and SARS-CoV-2 detection in nasopharyngeal swabs by RT-PCR from questionnaires and electronic medical records. Results: The median age TRANS of patients was 40 and 50 years at Mobile Cabin Hospital and Tongji Hospital, respectively. Of 534 COVID-19 patients, 25 patients (4.68%) presented with conjunctival congestion and 3 patients had conjunctival congestion as the initial symptom. The average duration of conjunctival congestion was 4.9 {+/-} 2.6 days (mean [SD]), ranging from 2 to 10 days. Dry eye (112, 20.97%), blurred vision HP blurred vision MESHD (68, 12.73%), and foreign body sensation (63, 11.80%) ranked as the top three COVID-19 related ocular symptoms. Notably, a total of 332 COVID-19 patients (62%) had a hand-eye contact history. We also found that some COVID-19 patients had a history of eye disease MESHD, including conjunctivitis HP conjunctivitis MESHD (33, 6.18%), dry eye MESHD (24, 4.49%), keratitis HP keratitis MESHD (14, 2.62%), cataract HP cataract MESHD (9, 1.69%), and diabetic retinopathy MESHD retinopathy HP (5, 0.94%). In consistent with previous studies, the most common clinical symptoms were fever HP fever MESHD, cough HP cough MESHD, and fatigue HP fatigue MESHD. Patients, 60.5% in Mobile Cabin Hospital and 67.5% in Tongji Hospital, respectively were confirmed with positive SARS-CoV-2 detection. Conclusions: Conjunctival congestion was one of the COVID-19 related ocular symptoms, which may have clinical diagnostic significance. It is essential to provide eye-care equipment and strengthen education on eye protection, as dirty hand-eye contact might be a high risk factor of COVID-19. Further detailed and comprehensive ophthalmological guidance is needed for COVID-19 control.
