    BACKGROUND: Symptoms of SARS-CoV-2 infection MESHD in children TRANS are nonspecific and shared with other common acute viral illnesses ( fever HP fever MESHD, respiratory or gastrointestinal symptoms MESHD, and cutaneous signs), thus making clinical differential diagnosis tricky. In Italy, first line management of pediatric care is handed over to Primary Care Pediatricians (PCPs), who were not allowed to directly perform diagnostic tests during the recent COVID-19 outbreak. Without a confirmatory diagnosis, PCPs could only collect information on ''COVID-19 like symptoms'' rather than identify typical COVID-19 symptoms. AIM: To evaluate the prevalence SERO of COVID-19 like symptoms in outpatient children TRANS, during Italian lockdown. To provide PCPs a risk score to be used in clinical practice during the differential diagnosis process. METHODS: A survey was submitted to 50 PCPs (assisting 47,500 children TRANS) from 7 different Italian regions between the 4th of March and the 23rd of May 2020 (total and partial lockdown period). COVID-19 like symptoms in the assisted children TRANS were recorded, as well as presence of confirmed/suspected cases in children TRANS's families, which was taken as proxy of COVID-19. Multivariable logistic regression was accomplished to estimate the risk of having suspected/ confirmed cases TRANS in families, considering symptoms as potential determinants. RESULTS: 2,300 children TRANS (4.8% of overall survey population) fell HP ill with COVID-19 like symptoms, 3.1% and 1.7% during total and partial lockdown period respectively. The concurrent presence of fatigue HP fatigue MESHD, cough HP, and diarrhea HP diarrhea MESHD in children TRANS, in absence of sore throat/ earache MESHD and abnormal skin signs, represents the maximum risk level of having a suspected/ confirmed case TRANS of COVID-19 at home. CONCLUSIONS: The percentage of children TRANS presenting COVID-19 like symptoms at home has been remarkable also during the total lockdown period. The present study identified a pattern of symptoms which could help, in a cost-effective perspective, PCPs in daily clinical practice to define priorities in addressing children TRANS to the proper diagnostic procedure.

    The current pandemic caused by SARS-CoV-2 has posed an important threat to the human health, healthcare systems, economy, and structure of societies. In Colombia, the first case was diagnosed on March 6, 2020 , with exponential progressive growth, and there were >200,000 confirmed cases TRANS as of July 20, 2020, in this cross-sectional, analytical, and observational study, we focused on the demographic, epidemiologic, and clinical characteristics of patients with confirmed SARS-CoV-2 infection MESHD at a highly complex institution in Latinamerica, with special emphasis on gastrointestinal symptoms. Methods: Demographic and clinical data were collected, results related to the outcomes such as hospitalization time, admission to ICU, need for orotracheal intubation, and death MESHD were also included. Statistical analyses were conducted using Stata software V.15. Results: We included 72 patients RT-PCR positive for SARS-CoV-2 (34 women and 38 men) with age TRANS 47.5 17.7 years; 17 (23.6%) presented at least one of the gastrointestinal symptoms ( nausea/vomiting HP nausea/vomiting MESHD vomiting MESHD, abdominal pain HP abdominal pain MESHD, and/or diarrhea HP diarrhea MESHD). 13 (76.47%) presented with diarrhea HP diarrhea MESHD, 29.41% with nausea/vomiting HP nausea/vomiting MESHD vomiting MESHD, and five (29.41%) with abdominal pain HP abdominal pain MESHD. Diarrhea HP Diarrhea MESHD in 18.06% of all those infected with SARS-CoV-2 at the time of consultation, which was the most common digestive symptom. No significant differences were observed in requirement for endotracheal intubation, hospitalization, ICU admission, and fatal outcome between the NGIS and GIS groups (p:0.671, 0.483, 1,000, and 1,000). Conclusion: In our study, patients with gastrointestinal symptoms had no significant differences in disease severity, admission to ICU or death MESHD compared to those who did not have such symptoms.

    Objectives: To discuss the prevention and containment of COVID-19 at a general hospital in Shenzhen China; to analyze the epidemiological and clinical characteristics of its confirmed patients, which is intended to provide a model for other hospitals in COVID-19 management.Methods: The General Hospital of Shenzhen University sets up 4 medical zones relative to the COVID-19 prevention and containment. In so doing, the suspected patients classified into different kind of ward receive different treatment (Classified and Separated Treatment). The epidemiological distribution and clinical characteristics of 28 confirmed cases TRANS in the hospital were analyzed.Results: There are no medical personnel infected cases, no cross-infection MESHD among the patients in the hospital, and no misdiagnosis or missed diagnosis of COVID-19. The majority of cases in the group is from 15 to 60 years old, 25 cases had a definite travel TRANS history or close contact TRANS history in the epidemic area, and parents TRANS and spouses of the confirmed patients are the main contact groups. Fever HP Fever MESHD and respiratory symptoms have a high proportion, 4 diarrhea HP diarrhea MESHD and 4 asymptomatic TRANS cases. Additionally, the decrease of lymphocyte is observed in 8 cases. Chest CT scan shows viral pneumonia HP pneumonia MESHD in 14 cases,All patients were confirmed by nucleic acid tests.Conclusions: Classified and Separated Treatment facilitates management of COVID-19 in the general hospital. Relative to suspected patients in the general hospital, diagnosis matters more than treatment. Epidemiological history, lymphocyte count, and chest CT scan play an important role as the indicator in early diagnosis of COVID-19.

    Background: Prolonged nucleic acid conversion and false-negative results of real-time reverse transcription polymerase chain reaction (RT-PCR) might occur in some patients with COVID-19 rather than recurrence of infection MESHD. Here, we reported four cases of COVID-19 with prolonged nucleic acid conversion and false-negative results of RT-PCR in our institution.Case presentation: Case 1: A 36-year-old- male TRANS patient complained of coughing HP up phlegm one week before admission. His chest X-rays showed mild pneumonia HP pneumonia MESHD in the right lung. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also had negative results of RT-PCR twice (the 6th and 8th tests) from a total of 11 swab tests. Case 2: A 54-year-old- male TRANS patient complained of shortness of breath MESHD that worsened with activity. He had a comorbidity of diabetes MESHD. His chest X-rays showed inhomogeneous opacity on bilateral paracardial and lateral aspects. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also had negative results of RT-PCR once (the 5th test) from a total of 8 swab tests. Case 3: A 47-year-old man presented with complaints of fever HP fever MESHD, cough HP cough MESHD, sore throat, and diarrhea HP diarrhea MESHD. He had comorbidities of asthma HP asthma MESHD and heart rhythm disorders MESHD. His chest X-rays showed bilateral pneumonia HP pneumonia MESHD. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also showed negative results of RT-PCR twice (the 4th and 6th tests) from a total of 11 swab tests. Case 4: A 56-year-old- female TRANS complained of lethargy HP lethargy MESHD and diarrhea HP diarrhea MESHD. She has a history of hyperthyroidism HP hyperthyroidism MESHD. His chest X-rays showed bilateral pneumonia HP pneumonia MESHD. She was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, she also had negative results of RT-PCR twice (the 2nd and 10th tests) from a total of 14 swab tests.Conclusions: Our cases further confirmed TRANS the occurrence of prolonged nucleic acid conversion and the possibility of false negative results of RT-PCR in patients with COVID-19 instead of recurrence of infection MESHD. These findings might have an implication on the management of patients with COVID-19 who have already clinically and radiologically recovered, particularly related to subsequent spreading of the infection MESHD in the community.

    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 was to identify symptoms and their frequencies of COVID-19 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 articles. Eligibility criteria: Suitable articles were selected manually with selection criteria and 14 original articles included in meta-analysis. Data abstraction and analysis: PRISMA guidelines, used for data abstraction and a table was generated by feeding it with numbers and proportions of each symptom described. 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 were calculated.Results: Selected 14 studies, either cross-sectional or cohort studies are analyzed. There were 2,660 confirmed cases TRANS of COVID-19. The 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 identified from the meta-analysis and additional 7 symptoms were identified from reference searching. The most common symptoms were ( prevalence SERO >50%): fever HP 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%): tonsil swelling MESHD, haemoptysis, conjunctival injection, lymphadenopathy HP lymphadenopathy MESHD and rash MESHD. Conclusion and implications of key findings: We found (25/32, from meta-analysis) symptoms to be present in =>5% of cases which could be considered as “typical” symptoms of COVID-19. The list of symptoms we identified is 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.

    Data on the novel coronavirus disease MESHD 2019 (COVID-19) in children TRANS are limited, and studies from Europe are scarce. We analyzed the clinical severity and epidemiologic aspects of COVID-19 in consecutive children TRANS aged TRANS 0 – 18 years, referred with a suspicion of COVID-19 between February 1, and April 15, 2020. RT-PCR on a nasopharyngeal swab was used to confirm COVID-19. 319 children TRANS met the criteria of a suspected case. COVID-19 was diagnosed in 15/319 (4.7%) patients (8 male TRANS; mean age TRANS 10.5 years). All of them had household contact TRANS with an infected relative. Five (33.3%) patients were asymptomatic TRANS. In 9/15 (60.0%) children TRANS, the course of the disease was mild, and in 1/15 (6.7%), it was moderate, with the following symptoms: fever HP fever MESHD (46.7%), cough HP (40%), diarrhea HP diarrhea MESHD (20%), vomiting HP vomiting MESHD (13.3%), rhinitis HP rhinitis MESHD (6.7%), and shortness of breath MESHD (6.7%). In the COVID-19-negative patients, other infections were confirmed TRANS infections were confirmed MESHD, including influenza in 32/319 (10%). The clinical course of COVID-19 and influenza differed significantly based on the clinical presentation. In conclusion, the clinical course of COVID-19 in children TRANS is usually mild or asymptomatic TRANS. In children TRANS suspected of having COVID-19, other infections should not be overlooked. The main risk factor for COVID-19 in children TRANS is household contact TRANS with an infected relative.

    Background: A new pathogenic disease named COVID-19 became a global threat, first reported in Wuhan, China, in December 2019. The number of affected cases growing exponentially and now, more than 210 countries confirmed the cases TRANS. Objective: This meta-analysis aims to evaluate risk factors, the prevalence SERO of comorbidity, and clinical characteristics in COVID-19 death MESHD patients compared to survival patients that can be used as a reference for further research and clinical decisions. Methods: PubMed, Science Direct, SAGE were searched to collect data about demographic, clinical characteristics, and comorbidities of confirmed COVID-19 patients from January 1, 2020, to May 17, 2020. Meta-analysis was performed with the use of Review Manager 5.3 Results: Eighty-five studies were included in Meta-analysis, including a total number of 67,299 patients with SARS-CoV-2 infection MESHD. Males TRANS are severely affected or died than females TRANS (OR = 2.26, p < 0.00001; OR = 3.59, p < 0.00001) are severely affected, or died by COVID-19 and cases with age TRANS [≥]50 are at higher risk of death MESHD than age TRANS <50 years (OR=334.23). Presence of any comorbidity or comorbidities like hypertension HP hypertension MESHD, cardiovascular disease MESHD, diabetes MESHD, cerebrovascular disease MESHD, respiratory disease MESHD, kidney disease MESHD, liver disease MESHD, malignancy MESHD significantly increased the risk of death compared to survival (OR = 3.46, 3.16, 4.67, 2.45, 5.84, 2.68, 5.62, 2.81,2.16). Among the clinical characteristics such as fever HP fever MESHD, cough HP cough MESHD, myalgia HP myalgia MESHD, diarrhea HP diarrhea MESHD, abdominal pain HP abdominal pain MESHD, dyspnea HP dyspnea MESHD, fatigue HP fatigue MESHD, sputum production, chest tightness HP chest tightness MESHD headache HP and nausea or vomiting HP nausea or vomiting MESHD, only fatigue HP fatigue MESHD (OR = 1.31, 95%) and dyspnea HP dyspnea MESHD increased the death significantly (OR= 1.31, 4.57). The rate of death of COVID-19 cases is 0.03-times lower than the rate of survival (OR = 0.03). Conclusion Our result indicates that male TRANS patients are affected severely or died, the rate of death is more in the age TRANS [≥]50 group, and the rate of death is affected by comorbidities and clinical symptoms.

    Objective: To clarify the clinical and medical expense characteristics of COVID-19. Methods: In this retrospective, single-center study, 55 cured cases with confirmed TRANS COVID-19 were analyzed for demographic, epidemiological, clinical, and radiological features and medical expense data.Results: The average age TRANS of the 54 successfully treated patients with COVID-19 was 53.2 years old (SD 19.0), including 27 men and 27 women. Off this, 31 (57.4%) patients had chronic diseases MESHD. Patients commonly had clinical manifestations of fever HP fever MESHD (45 [83.3%] patients), cough HP (29[54.7%] patients), expectoration (28 [51.9%] patients), fatigue HP fatigue MESHD (24[44.4%] patients) and diarrhea HP diarrhea MESHD (8[14.8%] patients) on admission. There was a 10-day interval from the onset of signs and symptoms to hospital admission. About 80% of them got recovery after a two-week treatment. The mean interval from the onset of signs and symptoms to hospital discharge was 20.5 (IQR 16-29) days. The median total medical expense of the treated patient, in general, was 2579.6 (IQR 1366.1-4837.6) U.S. dollars. Still, the median medical expense was 8904.1 (IQR 6660.1- 27143.8) U.S. dollars in patients with more than five comorbid illnesses during the treatment.Conclusion: There is a 3-week interval from the onset of signs and symptoms to cure, and most hospitalized patients get recovery within two weeks. The total medical expense of cases with more than five comorbid conditions during the treatment is higher. Quite a few COVID-19 cases with other serious diseases are likely to account for most of the total medical expenses.

    Background: The introduction and rapid transmission TRANS of SARS CoV2 in the United States resulted in implementation of methods to assess, mitigate and contain the resulting COVID-19 disease based on limited knowledge. Screening for testing has been based on symptoms typically observed in inpatients, yet outpatient symptom complexes may differ. Methods: Classification and regression trees (CART) recursive partitioning created a decision tree classifying enrollees into laboratory- confirmed cases TRANS and non-cases. Demographic and symptom data from patients ages TRANS 18-87 years who were enrolled from March 29-April 26, 2020 were included. Presence or absence of SARSCoV2 was the target variable. Results: Of 736 tested, 55 were positive for SARS-CoV2. Cases significantly more often reported chills HP, loss of taste/smell, diarrhea HP diarrhea MESHD, fever HP fever MESHD, nausea/vomiting HP nausea/vomiting MESHD and contact with a COVID-19 case, but less frequently reported shortness of breath MESHD and sore throat. A 7-terminal node tree with a sensitivity SERO of 96% and specificity of 53%, and an AUC of 78% was developed. The positive predictive value SERO for this tree was 14% while the negative predictive value SERO was 99%. Almost half (44%) of the participants could be ruled out as likely non-cases without testing. Discussion: Among those referred for testing, negative responses to three questions could classify about half of tested persons with low risk for SARS-CoV2 and would save limited testing resources. These questions are: was the patient in contact with a COVID-19 case? Has the patient experienced 1) a loss of taste or smell; or 2) nausea or vomiting HP nausea or vomiting MESHD vomiting MESHD? The outpatient symptoms of COVID-19 appear to be broader than the well-known inpatient syndrome.

    Back ground: Severe respiratory tract infection HP respiratory tract infection MESHD caused by family of Corona viruses has become world pandemic and is claiming many lives. In this study we have described the first 33 cases diagnosed, admitted and treated in Ethiopia COVID treatment center with the aim of contributing some information to the local and global effort of controlling the pandemic.Method: Descriptive study was conducted on the first 33 consecutive RT-PCR confirmed COVID 19 cases diagnosed and managed at Ekka-Kotebe COVID treatment center in Addis Ababa, Ethiopia.Result: Data of the first 33 COVID 19 confirmed patients treated at Ekka-kotebe COVID treatment center was analyzed. The median age TRANS of the cases was 36 years. Cough HP, headache HP headache MESHD and fever HP fever MESHD were the most frequent symptoms in the firs 33 COVID 19 cases reported in this study. Diarrhea HP Diarrhea MESHD, sore throats, loss of taste and/or smell sensation were among the rare symptoms. Most (84.8%) had mild to moderate disease and 15.2%(n = 5) were critical at the time of admission. Among the five ICU admissions, four patients required invasive mechanical ventilation. Both mild and moderate cases were managed in the general ward with or without low flow oxygen treatment. Thirty cases were discharged after two pairs of nasopharyngeal and oropharyngeal samples turned negative for SARS CoV2. Three cases from the ICU died while on mechanical ventilator. Age TRANS of the two deaths was 65 years and one was 60 years. With the exception of three, all cases were either imported from abroad or had contact with confirmed case TRANS.
