    Introduction: COVID-19 is an emerging, rapidly evolving global situation, infecting over 25 million people and causing more than 850,000 deaths. Several signs and symptoms have been described to be characteristic of the disease. However, there is a dearth of report on the description of the clinical characteristics of the disease in patients from Nigeria. This study was designed to provide a description of the clinical and demographic characteristics of COVID-19 patients in Nigeria. Methods: This study is a case series that includes patients that are evaluated between June and August 30, 2020, and diagnosed with COVID-19. Patient health records were reviewed and evaluated to describe the clinical characteristics on presentation. Results: A total of 154 COVID-19 patients were included in this study, with a mean age TRANS (S.D.) of 46.16 (13.701). Most of the patients survived (mortality rate of 2.6%), and were symptomatic (89.6%). There were more males TRANS (74.7%) than females TRANS, and the most common symptoms were fever HP fever MESHD, breathing difficulty, dry cough and malaise MESHD cough HP and malaise. Co-morbidities were also present in almost half of the study participants (49.4%). Conclusion: This study presents the most extensive description, to date, on the clinical and demographic characteristics of COVID-19 patients in Nigeria. Males TRANS are more likely than females TRANS to be infected with COVID-19 and the most occurring symptoms are fever HP fever MESHD, breathing difficulty, malaise, dry cough MESHD cough HP and chest pain HP chest pain MESHD. Old age TRANS and the presence of co-morbidities may also be associated with developing the severe disease. Key words: COVID-19, SARS-CoV-2, Signs, Symptoms, Nigeria.

    Importance: Fatality rates related to COVID-19 in Japan have been low compared to Western Countries and have decreased despite the absence of lockdown. Serological tests SERO monitored across the course of the second wave can provide insights into the population-level prevalence SERO and dynamic patterns of COVID-19 infection MESHD. Objective: To assess changes in COVID-19 seroprevalence SERO among asymptomatic TRANS employees working in Tokyo during the second wave. Design: We conducted an observational cohort study. Healthy volunteers working for a Japanese company in Tokyo were enrolled from disparate locations to determine seropositivity against COVID19 from May 26 to August 25, 2020. COVID-19 IgM and IgG antibodies SERO were determined by a rapid COVID19 IgM/IgG test kit using fingertip blood SERO. Across the company, tests were performed and acquired weekly. For each participant, serology tests were offered twice, separated by approximately a month, to provide self-reference of test results and to assess for seroconversion and seroreversion. Setting: Workplace setting within a large company. Participants: Healthy volunteers from 1877 employees of a large Japanese company were recruited to the study from 11 disparate locations across Tokyo. Participants having fever HP fever MESHD, cough HP cough MESHD, or shortness of breath MESHD at the time of testing were excluded. Main Outcome(s) and Measure(s): Seropositivity rate (SPR) was calculated by pooled data from each two-weeks window across the cohort. Either IgM or IgG positivity was defined as seropositive. Changes in immunological status against SARS-CoV-2 were determined by comparing results between two tests obtained from the same individual. Results: Six hundred fifteen healthy volunteers (mean + SD 40.8 + 10.0; range 19-69; 45.7 % female TRANS) received at least one test. Seroprevalence SERO increased from 5.8 % to 46.8 % over the course of the summer. The most dramatic increase in SPR occurred in late June and early July, paralleling the rise in daily confirmed cases TRANS within Tokyo, which peaked on August 4. Out of the 350 individuals (mean + SD 42.5 + 10.0; range 19-69; 46.0 % female TRANS) who completed both offered tests, 21.4 % of those individuals who tested seronegative became seropositive and seroreversion was found in 12.2 % of initially seropositive participants. 81.1% of IgM positive cases at first testing became IgM negative in approximately one month. Conclusions and Relevance: COVID-19 infection MESHD may have spread widely across the general population of Tokyo despite the very low fatality rate. Given the temporal correlation between the rise in seropositivity and the decrease in reported COVID-19 cases that occurred without a shut-down, herd immunity may be implicated. Sequential testing for serological SERO response against COVID-19 is useful for understanding the dynamics of COVID-19 infection at the population-level.

    Background: Due to the wide spread of SARS-CoV2 around the world, the risk of death MESHD in individuals with metabolic comorbidities has dangerously increased. Mexico has a high number of infected individuals and deaths by COVID-19, as well as an important burden of metabolic diseases MESHD. However, reports about features of Mexican individuals with COVID-19 are scarce. The aim of this study was to evaluate demographic features, clinical characteristics, and the pharmacological treatment of individuals who died by COVID-19 in the south of Mexico. Methods: We performed an observational study including 185 deceased individuals with confirmed diagnosis of COVID-19. Data were retrieved from medical records. Categorical data was expressed as proportions (%) and numerical data were expressed as mean, standard deviation. Comorbidities and overlapping symptoms where plotted as Venn diagrams. Drug clusters were plotted as dendrograms. Results: The mean age TRANS was 59.53 years. There was a male TRANS predominance (60.1%). The mean hospital stay was 4.75 days. The most frequent symptoms were dyspnea HP dyspnea MESHD (88.77%), fever HP fever MESHD (71.42%) and dry cough MESHD cough HP (64.28%). Present comorbidities were diabetes MESHD (60.63%), hypertension HP hypertension MESHD (59.57%) and obesity HP obesity MESHD (43.61%). The main drugs used were azithromycin (60.6%), hydroxychloroquine (53.0%) and oseltamivir (27.3%). Conclusions: Mexican individuals who died of COVID-19 had shorter hospital stays, higher frequency of shortness of breath MESHD, and higher prevalence SERO of diabetes MESHD compared with individuals from other countries. Also, there was a high frequency of off-label use of drugs for their treatment.

    Background: Assigning meaningful probabilities of SARS CoV2 infection risk TRANS infection risk TRANS presents a diagnostic challenge across the continuum of care. Methods: We integrated patient symptom and test data using machine learning and Bayesian inference to quantify individual patient risk of SARS CoV 2 infection MESHD. We trained models with 100,000 simulated patient profiles based on thirteen symptoms, estimated local prevalence SERO, imaging, and molecular diagnostic performance SERO from published reports. We tested these models with consecutive patients who presented with a COVID 19 compatible illness at the University of California San Diego Medical Center over 14 days starting in March 2020. Results: We included 55 consecutive patients with fever HP fever MESHD (78%) or cough HP cough MESHD (77%) presenting for ambulatory (n=11) or hospital care (n=44). 51% (n=28) were female TRANS, 49% were age TRANS <60. Common comorbidities included diabetes MESHD (22%), hypertension HP hypertension MESHD (27%), cancer MESHD (16%) and cardiovascular disease MESHD (13%). 69% of these (n=38) were RT-PCR confirmed positive for SARS CoV2 infection, 11 had repeated negative nucleic acid testing and an alternate diagnosis. Bayesian inference network, distance metric learning, and ensemble models discriminated between patients with SARS CoV2 infection MESHD and alternate diagnoses with sensitivities SERO of 81.6 to 84.2%, specificities of 58.8 to 70.6%, and accuracies of 61.4 to 71.8%. After integrating imaging and laboratory test statistics with the predictions of the Bayesian inference network, changes in diagnostic uncertainty at each step in the simulated clinical evaluation process were highly sensitive to location, symptom, and diagnostic test choices. Conclusions: Decision support models that incorporate symptoms and available test results can help providers diagnose SARS CoV2 infection MESHD in real world settings.

    Background:As everyone knows, the pandemic COVID-19 is spreading in the whole world. The number of laboratory- confirmed cases TRANS reached 28,637,211 and that of the death cases was 917,404 in the world as of September 13th, 2020. We sought to analyse the clinical characteristics, laboratory findings and therapy of some cases with COVID-19.Methods: In this retrospective study, we extracted the data on 134 patients with laboratory-confirmed COVID-19 in Wuhan Xinzhou District People's Hospital from January 16th to April 24th , 2020. Cases were confirmed TRANS by real-time RT-PCR and abnormal radiologic findings. Outcomes were followed up until May 1th , 2020. Results: Co-infection MESHD infection and severe HP underlying diseases made it easier for a case with COVID-19 to develop to be a severe one or reach an outcome of death MESHD. Age TRANS above 60 years old, male TRANS and symptoms such as fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD, headaches HP headaches MESHD and fatigue HP fatigue MESHD were related to severe COVID-19 and an outcome of death MESHD. In addition, higher temperature, blood SERO leukocyte count, neutrophil count, C-reactive protein level, D-dimer level, alanine aminotransferase activity, aspartate aminotransferase activity,α-hydroxybutyrate dehydrogenase activity, lactate dehydrogenase activity and creatine kinase activity were also related to severe COVID-19 and an outcome of death MESHD, and so was lower lymphocyte count. Administration of gamma globulin seemed helpful for reducing the mortality of patients with severe COVID-19, however the P value was greater than 0.05 (P=0.180), which mean under the same condition, studies of larger samples are needed in the future.                 Conclusion: Multiple factors were related to severe COVID-19 and an outcome of death MESHD.  Administration of gamma globulin seemed helpful for reducing the mortality of severe cases. More related studies are needed in the future.

    (1) Background: This study aims to identify different clinical phenotypes in COVID-19 88 pneumonia HP pneumonia MESHD using cluster analysis and to assess the prognostic impact among identified clusters in 89 such patients. (2) Methods: Cluster analysis including 11 phenotypic variables was performed in a 90 large cohort of 12,066 COVID-19 patients, collected and followed-up from March 1, to July 31, 2020, 91 from the nationwide Spanish SEMI-COVID-19 Registry. (3) Results: Of the total of 12,066 patients 92 included in the study, most were males TRANS (7,052, 58.5%) and Caucasian (10,635, 89.5%), with a mean 93 age TRANS at diagnosis of 67 years (SD 16). The main pre-admission comorbidities were arterial 94 hypertension HP hypertension MESHD (6,030, 50%), hyperlipidemia HP hyperlipidemia MESHD (4,741, 39.4%) and diabetes mellitus HP diabetes mellitus MESHD (2,309, 19.2%). The 95 average number of days from COVID-19 symptom onset TRANS to hospital admission was 6.7 days (SD 7). 96 The triad of fever HP fever MESHD, cough HP cough MESHD, and dyspnea HP dyspnea MESHD was present almost uniformly in all 4 clinical phenotypes 97 identified by clustering. Cluster C1 (8,737 patients, 72.4%) was the largest, and comprised patients 98 with the triad alone. Cluster C2 (1,196 patients, 9.9%) also presented with ageusia and anosmia MESHD anosmia HP; 99 cluster C3 (880 patients, 7.3%) also had arthromyalgia, headache HP headache MESHD, and sore throat; and cluster C4 100 (1,253 patients, 10.4%) also manifested with diarrhea HP diarrhea MESHD, vomiting HP vomiting MESHD, and abdominal pain HP abdominal pain MESHD. Compared to 101 each other, cluster C1 presented the highest in-hospital mortality (24.1% vs. 4.3% vs. 14.7% vs. 102 18.6%; p<0.001). The multivariate study identified phenotypic clusters as an independent factor for 103 in-hospital death. (4) Conclusion: The present study identified 4 phenotypic clusters in patients with 104 COVID-19 pneumonia HP pneumonia MESHD, which predicted the in-hospital prognosis of clinical outcomes.

    Background: COVID-19 has changed the practice of surgery vividly all over the world. This has already lead to a huge burden of rescheduled pediatric surgical cases worldwide. Though children TRANS are less likely to be infected MESHD and suffer less when infected, there is a growing fear among health care workers of being self-infected, which is limiting the surgical care of children TRANS globally. This study aims to share our experiences with the outcome of COVID-19 in children TRANS who had a co-existing surgical emergency, which might help the pediatric surgeons globally to mitigate the effect of COVID 19 on pediatric surgery.Methods: This is a retrospective observational study. We reviewed the epidemiological, clinical, and laboratory data of all patients admitted in our surgery department through the emergency department and later diagnosed to have COVID-19 by RT-PCR. During April 2020 – June 2020. A nasopharyngeal swab was taken from all patients irrespective of symptoms to detect SARS CoV 2 by RT-PCR to identify and isolate asymptomatic TRANS patients and patients with atypical symptoms. We divided the test positive patients into 4 age groups TRANS for the convenience of data analysis. Data were retrieved from hospital records and analyzed using SPSS (version 25) software. Ethical permission was taken from the hospital ethical review board.Results: Total patients were 32. Seven (21.9%) of them were neonates. Twenty-four (75%) patients were male TRANS. The predominant diagnosis was acute abdomen followed by infantile hypertrophic pyloric stenosis MESHD pyloric stenosis HP (IHPS), myelomeningocele HP, and intussusception HP. Only two patients had mild respiratory symptoms MESHD ( dry cough MESHD cough HP). Fever HP Fever MESHD was present in 13 (40.6%) patients. Fourteen (43.8%) patients required surgical treatment. The mean duration of hospital stay was 5.5 days. One neonate with ARM died in the post-operative ward due to cardiac arrest HP cardiac arrest MESHD. No patient had hypoxemia HP hypoxemia MESHD or organ failure. Seven health care workers (5.51%) including doctors & nurses got infected with SARS Co V2 during this period.Conclusion: Our study has revealed a milder course of COVID-19 in children TRANS with minimal infectivity even when present in association with emergency surgical conditions. This might encourage a gradual restart to mitigate the impact of COVID-19 on children’s surgery.

    Background Due to the latent onset of novel coronavirus disease MESHD 2019 (COVID-19), it is important to identify patients with increased probabilities for disease progression early in order to implement timely medical strategies. This study aimed to identify the factors associated with severe COVID-19 and evaluate the current antiviral drugs, especially in severe patients.Methods This was a retrospective observational study performed at the No. 7 Hospital of Wuhan (Wuhan, China) with hospitalized patients confirmed with COVID-19 from January 11 to March 13, 2020. Multivariable logistic regression analysis was used to identify the associated factors of severe COVID. Treatment of antivirus drugs were collected and evaluated.Results Of the 550 patients, 292 (53.1%) were female TRANS and 277 (50.4%) were ≥ 60 years old. The most common symptom was fever HP fever MESHD (n = 372, 67.7%), followed by dry cough MESHD cough HP (n = 257, 46.7%), and dyspnea HP dyspnea MESHD (n = 237, 43.1%), and fatigue HP fatigue MESHD (n = 224, 40.7%). Among the severe patients, 20.2% required invasive ventilator support and 18.0% required non-invasive ventilator. The identified risk factors for severe cases were: age ≥ 60 years (odds ratio (OR) = 3.02, 95% confidence interval (CI): 1.13–8.08, P = 0.028), D-dimer > 0.243 µg/ml (OR = 2.734, 95%CI: 1.012–7.387, P = 0.047), and low oxygenation index (OR = 0.984, 95%CI: 0.980–0.989, P < 0.001). In severe cases, the benefits of arbidol alone was 73.3%, which was better than ribavirin (7/17, 41.2%, P = 0.029).Conclusions Age ≥ 60 years, D-dimer > 0.243 µg/ml, and lower oxygenation index were associated with severe cases. Arbidol might provide more clinical benefits in treating patients with severe COVID-19 compared with other antiviral drugs.

    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.

    Background: Coronavirus disease 2019 (COVID-19), a newly emerged respiratory disease MESHD caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2), has recently become pandemic. Clinical observation indicated that elderly TRANS patients had high incidence of severe pneumonia HP pneumonia MESHD and poor treatment efficacy. Therefore, this study was to clarify the characteristics of elderly TRANS patients aged TRANS 75 or older with COVID-19 pneumonia HP pneumonia MESHD in order to guide rational treatment for elderly TRANS patients. Methods: we enrolled 331 elderly TRANS patients aged TRANS 75 or older with confirmed COVID-19 in Huoshenshan hospital of Wuhan from February 3rd to March 31st. The cases were divided into general, serious and critical groups according to severity after hospitalization, and the difference among groups were compared by R package statistics software. Results: Compared with general group, serious and critical groups had more underlying comorbidities and higher incidence of cough HP cough MESHD, breath shortness MESHD and anorexia HP anorexia MESHD. Moreover, there existed obviously differences in many of laboratory indexes and CT images among them. serious and critical elderly TRANS patients were more likely to receive oxygen, mechanical ventilation, expectorant, corticosteroid, abidor, cephaloprin, imipenem, human serum SERO albumin (HSA), nutrition support, anti SARS-CoV-2 positive plasma SERO and actemra. Multivariate analysis of factors showed that male TRANS sex, hypertension HP hypertension MESHD, diabetes MESHD, renal diseases MESHD, breath shortness MESHD, neutrophil, platelet, creatinine, lactate dehydrogenase were the risk factor for serious and critical illness. While blood SERO cell (WBC) was the protective factor. Conclusion: elderly TRANS patients have high incidence of severe pneumonia HP pneumonia MESHD and poor treatment efficacy. The reasons might be that many of the elderly TRANS patients with COVID-19 pneumonia HP pneumonia MESHD have certain chronic disease MESHD, poor immune function and a meager response to the virus. the pathogenic mechanism of SARS-CoV-2 might be involved in the cell-mediated immunity and cytokine storms by acting on lymphocytes.
