    BACKGROUND: Symptoms of SARS-CoV-2 infection MESHD in children TRANS are nonspecific and shared with other common acute viral illnesses ( fever MESHD fever HP, respiratory or gastrointestinal symptoms, 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 MESHD fatigue HP, cough MESHD cough HP, and diarrhea MESHD diarrhea HP 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.

    Objective: Public cooperation to practice preventive health behaviours is essential to manage the transmission TRANS of infectious diseases MESHD such as COVID-19. We aimed to investigate beliefs about COVID-19 diagnosis, transmission TRANS and prevention that have the potential to impact the uptake of recommended public health strategies. Design: An online cross-sectional survey conducted May 8 to May 11 2020. Participants: A national sample of 1500 Australian adults TRANS with representative quotas for age TRANS and gender TRANS provided by online panel provider. Main outcome measure: Proportion of participants with correct/incorrect knowledge of COVID-19 preventive behaviours and reasons for misconceptions. Results: Of the 1802 potential participants contacted, 289 were excluded, 13 declined, and 1500 participated in the survey (response rate 83%). Most participants correctly identified washing your hands regularly with soap and water (92%) and staying at least 1.5m away from others (90%) could help prevent COVID-19. Over 40% (incorrectly) considered wearing gloves outside of the home would prevent them contracting COVID-19. Views about face masks were divided. Only 66% of participants correctly identified that regular use of antibiotics would not prevent COVID-19. Most participants (90%) identified fever MESHD fever HP, fatigue MESHD fatigue HP and cough MESHD cough HP as indicators of COVID-19. However, 42% of participants thought that being unable to hold your breath for 10 seconds without coughing MESHD coughing HP was an indicator of having the virus. The most frequently reported sources of COVID-19 information were commercial television channels (56%), the Australian Broadcasting Corporation (43%), and the Australian Government COVID-19 information app (31%). Conclusions: Public messaging about hand hygiene and physical distancing to prevent transmission TRANS appear to have been effective. However, there are clear, identified barriers for many individuals that have the potential to impede uptake or maintenance of these behaviours in the long-term. Currently these non-drug interventions are our only effective strategy to combat this pandemic. Ensuring ongoing adherence to is critical.

    Objective: Older adults TRANS have been continuously reported to be at higher risk for adverse outcomes of Covid-19. We aimed to describe clinical characteristics and early outcomes of the older Covid-19 patients hospitalized in our center comparatively with the younger patients, and also to analyze the triage factors that were related to the in-hospital mortality of older adults TRANS.Design: Retrospective; observational studySetting: Istanbul Faculty of Medicine hospital, TurkeyParticipants: 362 hospitalized patients with laboratory-confirmed Covid-19 from March 11 to May 11, 2020.Measurements: The demographic information; associated comorbidities; presenting clinical, laboratory, radiological characteristics on admission and outcomes from the electronic medical records were analyzed comparatively between the younger (<65 years) and older (≥65 years) adults TRANS. Factors associated with in-hospital mortality of the older adults TRANS were analyzed by multivariate regression analyses.Results: The median age TRANS was 56 years (interquartile range [IQR], 46-67), and 224 (61.9%) were male TRANS. There were 104 (28.7%) patients ≥65 years of age TRANS. More than half of the patients (58%) had one or more chronic comorbidity. The three most common presenting symptoms in the older patients were fatigue MESHD fatigue HP/ myalgia MESHD myalgia HP (89.4%), dry cough MESHD cough HP (72.1%), and fever MESHD fever HP (63.5%). Cough MESHD Cough HP and fever MESHD fever HP were significantly less prevalent in older adults TRANS compared to younger patients (p=0.001 and 0.008, respectively). Clinically severe pneumonia MESHD pneumonia HP was present in 31.5% of the study population being more common in older adults TRANS (49% vs. 24.4%) (p<0.001). The laboratory parameters that were significantly different between the older and younger adults TRANS were as follows: the older patients had significantly higher CRP, D-dimer, TnT, pro-BNP, procalcitonin levels, higher prevalence SERO of lymphopenia MESHD lymphopenia HP, neutrophilia HP, increased creatinine, and lower hemoglobin, ALT, albumin level (p<0.05). In the radiological evaluation, more than half of the patients (54.6%) had moderate-severe pneumonia MESHD pneumonia HP, which was more prevalent in older patients (66% vs. 50%) (p=0.006). The adverse outcomes were significantly more prevalent in older adults TRANS compared to the younger patients (ICU admission, 28.8% vs. 8.9%; mortality, 23.1% vs. 4.3%, p<0.001).  Among the triage evaluation parameters, the only factor associated with higher mortality was the presence of clinically severe pneumonia MESHD pneumonia HP on admission (Odds Ratio=12.3, 95% confidence interval=2.7-55.5, p=0.001).Conclusion: Older patients presented with more prevalent chronic comorbidities, less prevalent symptomatology but more severe respiratory signs and laboratory abnormalities than the younger patients. Among the triage assessment factors, the clinical evaluation of pulmonary involvement came in front to help clinicians to stratify the patients for mortality risk.

    Objective: To report three patients infected with COVID-19 with severe respiratory syndrome MESHD requiring intubation, who developed acute demyelinating encephalomyelitis MESHD (ADEM). Method: Patient data were obtained from medical records from the North Memorial Health Hospital, Robbinsdale, MN, USA Results: Three patients (two men and one woman, aged TRANS 38 - 63) presented with fatigue MESHD fatigue HP, cough MESHD cough HP and fever MESHD fever HP leading to development of acute respiratory distress HP syndrome MESHD secondary to COVID-19 infection MESHD requiring intubation and ventilatory support. Two patients were unresponsive, one with strong eye deviation to the left and the third patient had severe diffuse weakness. MRI in all patients showed findings consistent with ADEM. CSF showed elevated protein in all patients with normal cell count and no evidence of infection MESHD, including negative COVID-19 PCR. All three of the patients received Convalescent plasma SERO therapy for COVID-19. All patients were treated with intravenous corticosteroids and improved, although two responded minimally. Two patients treated with IVIG showed no further improvement. Conclusion: Neurological complications from COVID-19 are being rapidly recognized. Our three cases highlight the occurrence of ADEM as a postinfectious/immune mediated complication of COVID-19 infection MESHD, which may be responsive to corticosteroid treatment. Early recognition of this complication and treatment is important to avoid long term complications.

    Background: New coronavirus disease MESHD 2019 (COVID-19) poses a severe threat to human life, and causes a global pandemic. The purpose of current research is to explore the onset and progress of the pandemic with a novel perspective using Baidu Index.Methods: We collected the confirmed data of COVID-19 infection MESHD between January 11, 2020, and April 22, 2020, from the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University (JHU). Based on known literature, we obtained the search index values of the most common symptoms of COVID-19, including fever MESHD fever HP, cough MESHD cough HP, fatigue MESHD fatigue HP, sputum production, and shortness of breath. Spearman's correlation analysis was used to analyze the association between the Baidu index values for each COVID-19-related symptoms and the number of confirmed cases TRANS. Regional differences among 34 provinces/ regions were also analyzed. Results: Daily growth of confirmed cases TRANS and Baidu index values for each symptoms presented a robust positive correlation during the outbreak ( fever MESHD fever HP: rs=0.705, p=9.623×10-6; cough MESHD cough HP: rs=0.592, p=4.485×10-4; fatigue MESHD fatigue HP: rs=0.629, p=1.494×10-4; sputum production: rs=0.648, p=8.206×10-5; shortness of breath: rs=0.656, p=6.182×10-5). The average search-to-confirmed interval is 19.8 days in China ( fever MESHD fever HP: 22 days, cough MESHD cough HP: 19 days, fatigue MESHD fatigue HP: 20 days, sputum production: 19 days, and shortness of breath: 19 days). We discovered similar results in the top 10 provinces/regions, which had the highest cumulative cases. Conclusion: Search terms of COVID-19- related symptoms on the Baidu search engine can be used to early warn the outbreak of the epidemic. Relevant departments need to pay more attention to areas with high search index and take precautionary measures to prevent these potentially infected persons from spreading further. Baidu search engine can reflect the public's attention to the pandemic and regional epidemics of viruses. Based on changes in the Baidu index value, we can predict the arrival of the peak confirmed cases TRANS. The clinical characteristics related to COVID-19- including fever MESHD fever HP, cough MESHD cough HP, fatigue MESHD fatigue HP, shortness of breath, deserve more attention during the pandemic.

    Background: Currently, coronavirus disease MESHD-2019 (COVID-19) is continuously and rapidly circulating, resulting in serious and extensive impact on human health. Due to the absence of antiviral medicine for COVID-19 thus far, it is desperately need to develop the effective medicine. Traditional Chinese medicine (TCM) has been widely applied in the treatment of epidemic diseases MESHD in China, hoping to produce clinical efficacy and decrease the use of antibiotics and glucocorticoid. The aim of this study is to evaluate the efficacy and safety of Baidu Jieduan Granule in curing COVID-19. Methods/design: This multicenter, open-label randomized controlled trial is conducted 300 cases with COVID-19. The patients will be randomly (1:1) divided into treatment group or control group. All cases will receive standard therapy at the same time. The experiment group will receive Baidu Jieduan Granule treatment twice a day for 14 days. The outcomes are assessed at baseline and at 3, 5, 7, 14 days after treatment initiation. The primary outcome is the rate of symptom ( fever MESHD fever HP, fatigue MESHD fatigue HP, and coughing MESHD coughing HP) recovery. Adverse events will be monitored throughout the trial.Discussion: The study will provide a high-quality clinical evidence to support the efficacy and safety of Baidu Jieduan Granule in treatment of severe COVID-19, and also enrich the theory and practice of TCM in treating COVID-19.

    Objective : Data regarding the clinical characteristics of COVID-19 infection MESHD is rapidly accumulating. However, most studies thus far are based on hospitalized patients and lack longitudinal follow up. As the majority of COVID-19 cases are not hospitalized, prospective studies of symptoms in the population presenting to primary care are needed. Here, we assess the longitudinal dynamic of clinical symptoms in non-hospitalized individuals prior to and throughout the diagnosis of SARS-CoV-2 infection MESHD. Design Data on symptoms were extracted from electronic health records (EHR) consisting of both results of PCR tests and symptoms recorded by primary care physicians, and linked longitudinal self reported symptoms. Setting The second largest Health Maintenance Organization in Israel , Maccabi Health Services Participants From 1/3/2020 to 07/06/2020, information on symptoms from either surveys or primary care visits was available for 206,377 individuals, including 2,471 who tested positive for COVID-19. Main Outcomes Longitudinal prevalence SERO of clinical symptoms in COVID-19 infection MESHD diagnosed by PCR testing for SARS-CoV-2 from nasopharyngeal swabs. Results: In adults TRANS, the most prevalent symptoms recorded in EHR were cough MESHD cough HP (11.6%), fever MESHD fever HP (10.3%), and myalgia MESHD myalgia HP (7.7%) and the most prevalent self-reported symptoms were cough MESHD cough HP (21%), fatigue MESHD fatigue HP (19%) and rhinorrhea HP and/or nasal congestion (17%). In children TRANS, the most prevalent symptoms recorded in the EHR were fever MESHD fever HP (7%), cough MESHD cough HP (5.5%) and abdominal pain MESHD abdominal pain HP (2.4%) . Emotional disturbances were documented in 15.9% of the positive adults TRANS and 4.2% of the children TRANS. Loss of taste and smell, either self-reported or documented by a physician, 3 weeks prior to testing, were the most discriminative symptoms in adults TRANS (OR =11.18 and OR=5.47 respectively). Additional symptoms included self reported headache MESHD headache HP (OR = 2.03) and fatigue MESHD fatigue HP (OR = 1.73) and a documentation of syncope MESHD syncope HP, rhinorrhea HP (OR = 2.09 for both ) and fever MESHD fever HP (OR= 1.62 ) by a physician. Mean time to recovery TRANS was 23.5 +- 9.9 days. Children TRANS had a significantly shorter disease MESHD duration (21.7 +- 8.8 days, p-value=0.01). Several symptoms, including fatigue MESHD fatigue HP, myalgia MESHD myalgia HP, runny nose and shortness of breath were reported weeks after recovery. Conclusions As the COVID-19 pandemic progresses rapidly worldwide, obtaining accurate information on symptoms and their progression is of essence. Our study shed light on the full clinical spectrum of symptoms experienced by infected individuals in primary care, and may alert physicians for the possibility of COVID-19 infection MESHD.

    Objective: To examine the clinical characteristics and identify independent risk factors for in-hospital mortality of 2019 novel coronavirus (COVID-19) pneumonia MESHD pneumonia HP.Methods: A total of 156 patients diagnosed with COVID-19 pneumonia MESHD pneumonia HP at the central Hospital of Wuhan from January 29, 2020, to March 20, 2020 were enrolled in this single-centered retrospective study. Their epidemiological parameters, clinical presentations, underlying diseases MESHD, laboratory test results and disease MESHD outcomes were collected and analyzed. Results: The median age TRANS of enrolled patients was 66. Underlying diseases MESHD were identified in 101 patients, with hypertension MESHD hypertension HP being the most common one, followed by cardiovascular disease MESHD and diabetes. The most common symptoms identified upon admission were fever MESHD fever HP, cough MESHD cough HP, dyspnea MESHD dyspnea HP and fatigue MESHD fatigue HP. Compared to survival cases, patients who dead during hospitalization had higher plasma SERO levels of D-dimer, creatinine, creatine kinase, lactate dehydrogenase, lactate and lower percentage of lymphocytes (LYM [%]), platelet count and albumin levels. Most enrolled patients received anti-biotics and anti-viral treatment. In addition, 60 patients received corticosteroid and 51 received intravenous immunoglobulin infusion. 44 patients received noninvasive ventilation, 19 received invasive ventilation. Respiratory failure HP was the most frequently observed complication (106 [67.9%]), followed by sepsis MESHD sepsis HP (103 [66.0%]), acute respiratory distress HP syndrome MESHD (ARDS) (67 [42.9%]) and septic shock MESHD shock HP (50 [32.1%]). Multivariable regression suggested that advanced age TRANS (OR [odds ratio]= 1.059, 95% CI [confidence interval]: 1.011-1.110, P= 0.016) and elevated lactate level upon admission (OR= 2.411, 95% CI: 1.177-4.941, P= 0.016) were independent risk factors for in-hospital mortality for COVID-19 infection MESHD. Meanwhile, increased LYM (%) at admission (OR= 0.798, 95% CI: 0.728-0.876, P< 0.001) indicated a better prognosis. Conclusions: In this study, we discovered that age TRANS, LYM (%) and lactate level upon admission were independent factors that could influence in-hospital mortality rate.

    Background A striking characteristic of Coronavirus Disease MESHD 2019(COVID-19) is the coexistence of clinically mild and severe cases. A comprehensive analysis of multiple risk factors predicting progression to severity is clinically meaningful. Methods The patients were classified into moderate and severe groups. The univariate regression analysis was used to identify their epidemiological and clinical features related to severity, which were used as possible risk factors and were entered into a forward-stepwise multiple logistic regression analysis to develop a multiple factor prediction model for the severe cases.Results 255 patients (mean age TRANS, 49.1±SD 14.6) were included, consisting of 184 (72.2%) moderate cases and 71 (27.8%) severe cases. The common symptoms were dry cough MESHD cough HP (78.0%), sputum (62.7%), and fever MESHD fever HP (59.2%). The less common symptoms were fatigue MESHD fatigue HP (29.4%), diarrhea MESHD diarrhea HP (25.9%), and dyspnea MESHD dyspnea HP (20.8%). The univariate regression analysis determined 23 possible risk factors. The multiple logistic regression identified seven risk factors closely related to the severity of COVID-19, including dyspnea MESHD dyspnea HP, exposure history in Wuhan, CRP (C-reactive protein), aspartate aminotransferase (AST), calcium, lymphocytes, and age TRANS. The probability model for predicting the severe COVID-19 was P=1/1+exp (-1.78+1.02×age+1.62×high- transmission TRANS-setting-exposure +1.77×dyspnea+1.54×CRP+1.03×lymphocyte+1.03×AST+1.76×calcium). Dyspnea MESHD Dyspnea HP (OR=5.91) and hypocalcemia MESHD hypocalcemia HP (OR=5.79) were the leading risk factors, followed by exposure to a high- transmission TRANS setting (OR=5.04), CRP (OR=4.67), AST (OR=2.81), decreased lymphocyte count (OR=2.80), and age TRANS (OR=2.78). Conclusions This quantitative prognosis prediction model can provide a theoretical basis for the early formulation of individualized diagnosis and treatment programs and prevention of severe diseases MESHD.

    A 47-year-old physician suddenly noticed a persistent difficulty maintaining attention. He was awake, alert, and oriented. After two hours he developed fever MESHD fever HP, ageusia MESHD, and anosmia HP. He denied any previous history of psychiatric illness and was hydrated at the time of the subjective attention impairment. On admission, the patient remained oriented. He reported the persistence of attention problems, anosmia HP, and mild fatigue MESHD fatigue HP. The oxygen saturation 99% while he was breathing ambient air. Laboratory tests were unremarkable. A high-resolution computed tomography of the chest was normal. Nasopharyngeal and throat swabs specimens on reverse transcription-polymerase chain reaction analysis tested positive for SARS-CoV2. On illness day 3, the examination was unchanged, but he continued to complain of difficulties to stay focused. Then, he performed an objective attention test. The test demonstrated a moderate attentional impairment. On day 6, the patient reported a subjective worse in his concentration and performed a second test. Although his physical examination remained normal, the attention performance SERO was worse as compared to day 3. Eight hours after worsening of attention impairment, the patient’s oxygen saturation dropped to 94%. From illness days 9 to 14, the patient evolved with clinical improvement. On day 10, a third objective attention test indicated a mild deficit. On day 16, he did not report any other symptom and the attention test was completely normal. Then, the patient returned to work. Neurological symptoms had been previously described in COVID- 19 patients. However, no previous research had investigated early cognitive deficits preceding the traditional symptoms.
