    Objective: To evaluate the association of olfactory dysfunction MESHD ( OD MESHD) with hospitalization for COVID-19. Study Design: Multi-center cohort study. Setting: Emergency departments of thirteen COVID-19-designed hospitals in Kurdistan province, Iran. Subjects and Methods: Patients presenting with flu-like symptoms who tested positive by RT-PCR for COVID-19 between May 1st and 31st, 2020. At the time of presentation and enrollment, patients were asked about the presence of OD MESHD, fever HP fever MESHD, cough HP cough MESHD, shortness of breath MESHD, headache HP headache MESHD, rhinorrhea HP rhinorrhea MESHD and sore throat. The severity of OD MESHD was assessed on an 11-point scale from 0 (none) to 10 ( anosmia HP anosmia MESHD). Patients were either hospitalized or sent home for outpatient care based on standardized criteria. Results: Of 203 patients, who presented at a mean of 6 days into the COVID-19 disease course, 25 patients (12.3%) had new OD MESHD and 138 patients (68.0%) were admitted for their COVID-19. Patients admitted for COVID-19 had a higher prevalence SERO of all symptoms assessed, including OD MESHD (p<0.05 in all cases), and OD MESHD identified admitted patients with 84.0% sensitivity SERO and 34.3% specificity. On univariate logistic regression, hospitalization was associated with OD MESHD (odds ratio [OR] = 2.47, 95%CI: 1.085-6.911, p=0.049). However, hospitalization for COVID-19 was not associated with OD MESHD (OR=3.22, 95% CI: 0.57-18.31, p=0.188) after controlling for confounding demographics and comorbidities. Conclusion: OD MESHD may be associated with hospitalization for (and therefore more severe) COVID-19. However, this association between OD MESHD and COVID-19 severity is more likely driven by patient characteristics linked to OD MESHD, such as greater numbers of COVID-19 symptoms experienced or high-risk comorbidities.

    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 MESHD 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 HP (11.6%), fever HP fever MESHD (10.3%), and myalgia HP myalgia MESHD (7.7%) and the most prevalent self-reported symptoms were cough HP (21%), fatigue HP fatigue MESHD (19%) and rhinorrhea HP rhinorrhea MESHD and/or nasal congestion (17%). In children TRANS, the most prevalent symptoms recorded in the EHR were fever HP fever MESHD (7%), cough HP cough MESHD (5.5%) and abdominal pain HP abdominal pain MESHD (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 HP headache MESHD (OR = 2.03) and fatigue HP fatigue MESHD (OR = 1.73) and a documentation of syncope HP syncope MESHD, rhinorrhea HP rhinorrhea MESHD (OR = 2.09 for both ) and fever HP fever MESHD (OR= 1.62 ) by a physician. Mean time to recovery TRANS was 23.5 +- 9.9 days. Children TRANS had a significantly shorter disease duration (21.7 +- 8.8 days, p-value=0.01). Several symptoms, including fatigue HP fatigue MESHD, myalgia HP myalgia MESHD, runny nose and shortness of breath MESHD 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.

    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.

    Background: As countries in COVID-19 pandemic lockdown begin relaxation of shelter-in-place mitigation strategies, the role of serology testing escalates in importance. However, there are no clear guidelines as to when to use qualitative rapid diagnostic serology tests (RDTs) vs. SARS-CoV-2 viral RNA load (PCR) tests as an aid in acute diagnosis of patients presenting with flu-like symptoms, nor how to interpret serology test results in asymptomatic TRANS individuals or those with atypical COVID-19 symptomatology. Here we describe, in the context of the likely first case of COVID-19 in California, with an atypical presentation and not tested acutely, who nearly 3 months later was found to be IgM- and IgG+ positive for SARS-CoV-2 antibodies SERO, highlighting the role of RDT- based serology testing SERO and interpretation in retrospective diagnosis.Case Presentation: A 62-year-old male TRANS practicing neurosurgeon had onset of flu-like symptoms on January 20 with fatigue HP fatigue MESHD, slight cough HP only on deep inspiration, intermittent pleuritic chest pain MESHD chest pain HP unrelated to exertion, dyspnea HP dyspnea MESHD, and night sweats HP but without fever HP fever MESHD, sore throat or rhinorrhea HP rhinorrhea MESHD. He had recently traveled TRANS abroad but not to China. CT scan revealed right lower lobe infiltrate and effusion. Because of atypical symptoms, and low prevalence SERO of COVID-19 in January, community acquired pneumonia HP pneumonia MESHD was diagnosed and one week of doxycycline was prescribed without relief, followed by a second week of azithromycin with symptom remission. Three months later the physician-patient (author THL), tested positive for SARS-CoV-2 antibodies SERO by a serology point-of-care rapid diagnostic test (RDT).Conclusions: Serology testing may be an aid in acute diagnosis of COVID-19, especially in patients with atypical presentations, as well as in assessment of asymptomatic TRANS higher-risk persons such as healthcare workers for prior infection MESHD. Recommendations for serology testing and interpretation are explicated.

    The vast and rapid spread of COVID-19 calls for immediate action from policy-makers, and indeed, many countries have implemented lockdown measures to varying degrees. Here, we utilized nationwide surveys that assess COVID-19 associated symptoms to analyse the effect of the lockdown policy in Israel on the prevalence SERO of clinical symptoms in the population. Daily symptom surveys were distributed online and included questions regarding fever HP fever MESHD, respiratory symptoms MESHD, gastrointestinal symptoms MESHD, anosmia HP anosmia MESHD and ageusia MESHD. A total of 2,071,349 survey responses were analysed. We defined a single measure of symptoms, Symptoms Average (SA), as the mean number of symptoms reported by responders. Data were collected between March 15th to June 3rd, 2020. Notably, on the population level, following severe lockdown measures between March 15th and April 20th, SA sharply declined by 83.8% (p < 0.05), as did every single symptom, including the most common symptoms reported by our responders, cough HP cough MESHD and rhinorrhea HP and\or nasal congestion, which decreased by 74.1% (p < 0.05) and 69.6% (p < 0.05), respectively. Similarly, on the individual level, analysis of repeated responses from the same individuals (N = 208,637) over time also showed a decrease in symptoms during this time period. Moreover, the reduction in symptoms was observed in all cities in Israel, and in several stratifications of demographic characteristics. Different symptoms exhibit different reduction dynamics, suggesting differences in the nature of the symptoms or in the underlying medical conditions. Between May 13th and June 3rd, following several subsequent lockdown relief measures, we observed an increase in individual symptoms and in SA, which increased by 31.42%. Overall, these results demonstrate a profound decrease in a variety of clinical symptoms following the implementation of a lockdown in Israel, and an increase in the prevalence SERO of symptoms following the loosening of lockdown restrictions. As our survey symptoms are not specific to COVID-19 infection, this effect likely represents an overall nationwide reduction in the prevalence SERO of infectious diseases MESHD, including COVID-19. This quantification may be of major interest for COVID-19 pandemic, as many countries consider implementation of lockdown strategies.
