    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).

    Background: The 2019 coronavirus disease MESHD (COVID-19) has become an unprecedented public health crisis with nearly 16 million confirmed cases TRANS and 630,000 deaths worldwide. Methods: We retrospectively investigated the demographic, clinical, laboratory, radiological and treatment data of COVID-19 patients consecutively enrolled from January 18 to May 15, 2020, in Taihe and Jinzhou central hospital. Results: Of all 197 patients, the median age TRANS was 66.5 years (IQR 7-76), and 120 (60.9%) patients were males TRANS. We identified 88 (44.7%) of 197 COVID-19 patients as the disease progression (aggravation) cases. The aggravation cases tend to have more medical comorbidity: hypertension HP hypertension MESHD (34.1%), diabetes MESHD (30.7%), and presented with dyspnea HP dyspnea MESHD (34.1%), neutrophilia HP (60.2%), and lymphocytopenia MESHD (73.9%), compared with those without. And the patients with disease progression showed significantly higher level of Fibrinogen (Fbg), D-dimer, IL-6, C-reactive protein (CRP), procalcitonin (PCT), and serum SERO ferritin, and were more prone to develop organ damage in the liver, kidney, and heart (P<0.05). Multivariable regression showed that advanced age TRANS, comorbidities, lymphopenia HP lymphopenia MESHD, and elevated level of Fbg, lactate dehydrogenase (LDH), Cardiac troponin (CTnI), IL-6, serum SERO ferritin were the significant predictors of disease progression. Further, we investigated antibody SERO responses to SARS-CoV-2 and found that the levels of IgM and IgG were significantly higher in the disease progression cases compared to non-progression cases from 3 weeks after symptom onset TRANS. In addition, the disease progression group tended to peak later and has a more vigorous IgM/IgG response against SARS-CoV-2. Further, we performed Kaplan-Meier analysis and found that 61.6% of patients had not experienced ICU transfer or survival from hospital within 25 days from admission.Conclusions: Investigating the potential factors of advanced age TRANS, comorbidities and elevated level of IL-6, serum SERO ferritin and Kaplan-Meier analysis enables early identification and management of patients with poor prognosis. Detection of the dynamic antibody SERO may offer vital clinical information during the course of SARS-CoV-2 and provide prognostic value for patients infection MESHD.

    Objective: To explore the early clinical characteristics of coronavirus disease MESHD 2019 (COVID-19) and provide a reference for the early prevention and treatment of the disease.Methods: We collected and analyzed demographic data, medical history, exposure history, underline diseases MESHD, symptoms, signs, laboratory data, chest computed tomographic (CT) scans, and treatment measures of COVID-19 patients admitted to the Sixth People's Hospital of Hangzhou from January 20 to February 23, 2020.Results: Among 51 confirmed COVID-19 patients included in this study, 7.8% (4/51) patients were severe and 45.1% (23/51) were male TRANS. Median age TRANS was 43 years (IQR, 23). Fever HP Fever MESHD (54.9%, 28/51) and cough HP (52.9%, 27/51) were the main symptoms. 74.5% (38/51) patients had a history of exposure and 17.6% (9/51) patients had a history of hypertension HP hypertension MESHD. Importantly, most (60.8%, 31/51) patients had an increase of urine β2 microglobulin. In addition, the inflammation MESHD indexes (C-reactive protein and serum SERO amyloid A) of patients with elevated urine β2 microglobulin were significantly increased (p = 0.017 and p = 0.049) and lymphocytes count was significantly reduced (p = 0.012), compared with patients with normal urine β2 microglobulin. Correlation analysis showed that urine β2 microglobulin was positively correlated with C-reactive protein and serum SERO amyloid A; but negatively correlated with lymphocytes count.Conclusions: COVID-19 patients have obvious symptoms of lung injury MESHD, but the occurrence of early renal tubular injuries MESHD has to be monitored vigilantly.

    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.

    Background: Since December 2019, the outbreak of COVID-19 has spread quickly and thumped many countries and regions. The epidemic of central China was under the spotlight and attracted much more attentions. However, there are few reports describing COVID-19 patients in the regions outside of Wuhan, which are undergoing the change from sporadic imported cases to community-acquired transmission TRANS.Methods: The electronic medical records of 74 laboratory-confirmed patients of COVID-19 were retrospectively reviewed and analyzed. Their epidemiological, demographic, clinical and radiological characteristics were systematically summarized. The difference between severe patients and non-severe patients were also analyzed statistically.Results: The 74 COVID-19 patients were composed of 4 (5.4%) mild patients, 56 (75.7%) common patients, 13 (17.6%) severe patients and 1 (1.4%) critical patient. 43 were male TRANS, and 31 were female TRANS, with the average age TRANS 48.1±17.5. No significant difference of susceptibility was observed between genders TRANS, and almost people with all age TRANS were susceptible to SARS-CoV-2 infection MESHD. Before Jan 26, only imported sporadic cases were observed. However, from that day onward, family cluster infection MESHD cases increased dramatically, up to 70.3% (52/74), which were mainly from 15 family. The incubation period TRANS spanned from 0 to 19 days, with the median 5, and 81.4% had symptom onset TRANS within 7 days. At admission, 31.1% of patients had underlying diseases MESHD and the most common underlying diseases were hypertension HP hypertension MESHD (13.5%) and diabetes MESHD (5.4%). The most common symptoms were fever HP fever MESHD (90.5%), cough HP (75.7%), fatigue HP fatigue MESHD (36.5%) and chest distress (32.4%). 36.5% and 16.2% of patients had leukopenia HP leukopenia MESHD and lymphocytopenia MESHD. 43.2% of patients had increased C reactive protein (CRP), and 40.5% had higher erythrocyte sedimentation rate (ESR) and 21.6% had higher calcitonin. 74.3% of patients had obvious lesions in both lung lobes MESHD and 56.8% of lesions manifested as ground glass opacity. Compared with non-severe group, the severe/critical group were significantly older and had more underlying diseases. After treatment, all patients improved and were discharged. No medical professional infection MESHD and death case were reported.Conclusion: The epidemic of COVID-19 in Nanjing were mainly caused by family cluster infection MESHD. The entire prevalence SERO and illness were much milder than those of Wuhan. The disease of COVID-19 could be controlled and cured.
