    Objectives: The rapidly evolving coronavirus disease MESHD 2019 (COVID-19), was declared a pandemic by the World Health Organization on March 11, 2020. It was first detected in the city of Wuhan in China and has spread globally resulting in substantial health and economic crisis in many countries. Observational studies have partially identified the different aspects of this disease. Up to this date, no comprehensive systematic review for the clinical, laboratory, epidemiologic and mortality findings has been published. We conducted this systematic review and meta-analysis for a better understanding of COVID-19. Methods: We reviewed the scientific literature published from January 1, 2019 to March 3, 2020. Statistical analyses were performed with STATA (version 14, IC; Stata Corporation, College Station, TX, USA). The pooled frequency with 95% confidence intervals (CI) was assessed using random effect model. Publication bias was assessed and p <0.05 was considered a statistically significant publication bias. Results: Out of 1102 studies, 32 satisfied the inclusion criteria. A total of 4789 patients with a mean age TRANS of 49 years were evaluated. Fever HP Fever MESHD (83.0%, CI 77.5 to 87.6), cough HP cough MESHD (65.2%, CI 58.6 to 71.2) and myalgia HP myalgia MESHD/ fatigue HP fatigue MESHD (34.7, CI 26.0 to 44.4) were the most common symptoms. The most prevalent comorbidities were hypertension HP hypertension MESHD (18.5 %, CI 12.7 to 24.4) and Cardiovascular disease MESHD (14.9 %, CI 6.0 to 23.8). Among the laboratory abnormalities, elevated C-Reactive Protein (CRP) (72.0% (CI 54.3 to 84.6) and lymphopenia HP (50.1%, CI 38.0 to 62.4) were the most common findings. Bilateral ground-glass opacities (66.0%, CI 51.1 to 78.0) was the most common CT-Scan presentation. Pooled mortality rate was 6.6%, with males TRANS having significantly higher mortality compared to females TRANS (OR 3.4; 95% CI 1.2 to 9.1, P = 0.01). Conclusion: COVID-19 commonly presented with a progressive course of cough HP and fever HP with more than half of hospitalized patients showing leukopenia HP or a high CRP on their laboratory findings. Mortality associated with COVID19 was higher than that reported in studies in China with Males TRANS having a 3-fold higher risk of mortality in COVID19 compared to females TRANS.

    Background: Outbreak of COVID-19 has brought catastrophe to huge numbers of families. However, even though numerous tragedies occurred, there were few reports about family cluster infection MESHD in the academic journals. Methods: The electronic medical records of 10 COVID-19 patients in a big family were retrospectively reviewed and analyzed.Results: These 10 patients, 4 males TRANS and 6 females TRANS, were infected through two successive family feasts during Spring Festival. The infection source was a family member TRANS at asymptomatic TRANS state, who lived in Hubei but travelled TRANS to Nanjing. The median age TRANS of these 10 patients was 61.5, with the oldest 95 and youngest 38. The incubation period TRANS varied from 3 to 17 days, with the median of 5.5. Of them, 2 patients were asymptomatic TRANS. The most common symptoms at onset TRANS were fever HP (6/10) and dry cough MESHD cough HP (6/10). All of them displayed lesions on the chest CT. 40% of them had leukopenia HP leukopenia MESHD, neutropenia HP neutropenia MESHD and lymphopenia HP lymphopenia MESHD. After anti-virus treatment, all the patients significantly improved and were discharged. Conclusions: SARS-Cov-2 was highly contagious and so crafty that a varied incubation period TRANS did exist. Part of patients might be asymptomatic TRANS, which was the potential source of transmission TRANS. More measures for protection or quarantine should be taken at home if family member TRANS had travel TRANS history nearby the epidemic area.

    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.

    Abstract Background: The clinical outcomes of COVID-19 patients in Hubei and other areas are different. We aim to investigate the epidemiological and clinical characteristics of patient with COVID-19 in Hunan which is adjacent to Hubei. Methods: In this double-center, observational study, we recruited all consecutive patients with laboratory confirmed COVID-19 from January 23 to February 14, 2020 in two designated hospitals in Hunan province, China. Epidemiological and clinical data from patients' electronic medical records were collected and compared between mild, moderate and severe/critical group in detail. Clinical outcomes were followed up to February 20, 2020. Findings: 291 patients with COVID-19 were categorized into mild group (10.0%), moderate group (72.8%) and severe/critical group (17.2%). The median age TRANS of all patients was 46 years (49.8% were male TRANS). 86.6% patients had an indirect exposure history. The proportion of patients that had been to Wuhan in severe/critical group (48.0% vs 17.2%, p=0.006) and moderate group (43.4% vs 17.2%, p=0.007) were higher than mild group. Fever HP Fever MESHD (68.7%), cough HP (60.5%), and fatigue HP fatigue MESHD (31.6%) were common symptoms especially for severe and critical patients. Typical lung imaging finding were bilateral and unilateral ground glass opacity MESHD or consolidation. Leukopenia HP Leukopenia MESHD, lymphopenia HP lymphopenia MESHD and eosinopenia occurred in 36.1%, 22.7% and 50.2% patients respectively. Increased fibrinogen was detected in 45 of 58 (77.6%) patients with available results. 29 of 44 (65.9%) or 22 of 40 (55.0%) patients were positive in Mycoplasma pneumonia MESHD pneumonia HP or Chlamydia pneumonia MESHD pneumonia HP antibody test SERO respectively. Compared with mild or moderate group, severe/critical group had a relative higher level of neutrophil, Neutrophil-to-Lymphocyte Ratio, h-CRP, ESR, CK, CK-MB, LDH, D-dimer, and a lower level of lymphocyte, eosinophils, platelet, HDL and sodium (all p<0.01). Most patients received antiviral therapy and Chinese Medicine therapy. As of February 20, 2020, 159 (54.6%) patients were discharged and 2 (0.7%) patients died during hospitalization. The median length of hospital stay in discharged patients was 12 days (IQR: 10-15). Interpretation: The epidemiological and clinical characteristics of COVID-19 patients in Hunan is different from patients in Wuhan. The proportion of patients that had been to Wuhan in severe/critical group and moderate group were higher than mild group. Laboratory and imaging examination can assist in the diagnosis and classification of COVID-19 patients.

    Rationale: In late December 2019, an outbreak of acute respiratory illness MESHD, now officially named as COVID-19, or coronavirus disease MESHD 2019, emerged in Wuhan, China, now spreading across the whole country and world. More data were needed to understand the clinical characteristics of the disease. Objectives: To study the epidemiology, clinical features and outcomes of patients with COVID-19. Methods: we performed a single center, retrospective case series study in 221 patients with laboratory confirmed SARS-CoV-2 pneumonia MESHD pneumonia HP at a university hospital. Measurements and Main Results: The median age TRANS was 55.0 years and 48.9% were male TRANS and only 8 (3.6%) patients had a history of exposure to the Huanan Seafood Market. Compared to the non-severe pneumonia HP pneumonia MESHD patients, the median age TRANS of the severe patients was significantly older, and they were more likely to have chronic comorbidities. Most common symptoms in severe patients were high fever HP, anorexia HP anorexia MESHD and dyspnea HP dyspnea MESHD. On admission, 33.0% patients showed leukopenia HP leukopenia MESHD and 73.8% showed lymphopenia HP lymphopenia MESHD. In addition, the severe patients suffered a higher rate of co-infections MESHD with bacteria or fungus MESHD and they were more likely to developing complications. As of February 15, 2020, 19.0% patients had been discharged and 5.4% patients died. 80% of severe cases received ICU care, and 52.3% of them transferred to the general wards due to relieved symptoms, and the mortality rate of severe patients in ICU was 20.5%. Conclusions: The COVID-19 epidemic spreads rapidly by human-to-human transmission TRANS. Patients with elder age TRANS, chronic comorbidities, blood SERO leukocyte/lymphocyte count, procalcitonin level, co-infection MESHD infection and severe HP complications might increase the risk of poor clinical outcomes.

    BackgroundIn January 19, 2020, first case of 2019 novel coronavirus (2019-nCoV) pneumonia HP (COVID-19) was confirmed in Chongqing municipality, China. MethodsIn this retrospective, descriptive, multiple-center study, total of 267 patients with COVID-19 confirmed by real-time RT-PCR in Chongqing from Jan 19 to Feb 16, 2020 were recruited. Epidemiological, demographic, clinical, radiological characteristics, laboratory examinations, and treatment regimens were collected on admission. Clinical outcomes were followed up until Feb 16, 2020. Results267 laboratory-confirmed COVID-19 patients admitted to 3 designated-hospitals in Chongqing provincial municipality from January 19 to February 16, 2020 were enrolled and categorized on admission. 217 (81.27%) and 50 (18.73%) patients were categorized into non-severe and severe subgroups, respectively. The median age TRANS of patients was 48.0 years (IQR, 35.0-65.0), with 129 (48.3%) of the patients were more than 50 years of age TRANS. 149 (55.8%) patients were men. Severe patients were significantly older (median age TRANS, 71.5 years [IQR, 65.8-77.0] vs 43.0 years [IQR, 32.5-57.0]) and more likely to be male TRANS (110 [50.7%] vs 39 [78.0%]) and have coexisting disorders (15 [30.0%] vs 26 [12.0%]). 41 (15.4%) patients had a recent travel TRANS to Hubei province, and 139 (52.1%) patients had a history of contact with patients from Hubei. On admission, the most common symptoms of COVID-19 were fever HP 225(84.3%), fatigue HP (208 [77.9%]), dry cough HP (189 [70.8%]), myalgia HP or arthralgia HP (136 [50.9%]). Severe patients were more likely to present dyspnea HP (17 [34.0%] vs 26 [12.0%]) and confusion HP (10 [20.0%] vs 15 [6.9%]). Rales (32 [12.0%]) and wheezes (20 [7.5%]) are not common noted for COVID-19 patients, especially for the non-severe (11 [5.1%], 10 [4.6%]). 118 (44.2%). Most severe patients demonstrated more laboratory abnormalities. 231 (86.5%), 61 (22.8%) patients had lymphopenia HP, leukopenia HP and thrombocytopenia HP, respectively. CD4+ T cell counts decrease HP was observed in 77.1 % of cases, especially in the severe patients (45, 100%). 53.1% patients had decreased CD+3 T cell counts, count of CD8+T cells was lower than the normal range in part of patients (34.4%). More severe patients had lower level of CD4+ T cells and CD+3 T cells (45 [100.0%] vs 29[56.9%], 31 [68.9%] vs 20 [39.2%]). Most patients had normal level of IL-2, IL-4, TNF- and INF-{gamma}, while high level of IL-6 and IL-17A was common in COVID-19 patients (47 [70.1%], 35 [52.2%]). Level of IL-6, IL-17A and TNF- was remarkably elevated in severe patients (32 [84.2%] vs 15 [51.7%], 25 [65.8%] vs 10 [34.5%], 17 [44.7%] vs 5 [17.2%]). All patients received antiviral therapy (267, 100%). A portion of severe patients (38, 76.0%) received systemic corticosteroid therapy. Invasive mechanical ventilation in prone position, non-invasive mechanical ventilation, high-flow nasal cannula oxygen therapy was adopted only in severe patients with respiratory failure HP (5[10.0%], 35[70.0%], 12[24.0%]). Traditional Chinese medicine was adopted to most of severe patients (43,86.0%). Conclusion:Our study firstly demonstrated the regional disparity of COVID-19 in Chongqing municipality and further thoroughly compared the differences between severe and non-severe patients. The 28-day mortality of COVID-19 patients from 3 designed hospitals of Chongqing is 1.5%, lower than that of Hubei province and mainland China including Hubei province. However, the 28-mortality of severe patients was relatively high, with much higher when complications occurred. Notably, the 28-mortality of critically severe patients complicated with severe ARDS is considerably as high as 44.4%. Therefore, early diagnosis and intensive care of critically severe COVID-19 cases, especially those combined with ARDS, will be considerably essential to reduce mortality.
