    Importance: Healthcare workers (HCWs), including those with mild symptoms, may be an important source of COVID-19 within elderly TRANS care. Objective: To gain insight into the spread of SARS-CoV-2 among HCWs working in elderly TRANS care settings. Design: Cross-sectional study among HCWs working in elderly TRANS care in the South-East of the Netherlands, testing for SARS-CoV-2, between March 31 and April 17, 2020. Setting: HCWs working in geriatric rehabilitation, somatic and psychogeriatric wards or small-scale living groups and district nursing, with a total of 5245 HCWs within 4 organisations. Participants: 621 HCWs with mild respiratory symptoms. Main Outcomes: Number of HCWs testing positive for SARS-CoV-2 in pharyngeal swabs, using real-time reverse-transcriptase PCR targeting the SARS-CoV-2 E-gene, N-gene, and RdRP. HCWs filled out a survey to collect information on symptoms and possible sources of infection MESHD. Results: 133/615 (21.6%) HCWs tested positive for SARS-CoV-2, ranging from 15.6 to 44.4% per elderly TRANS care organisation, and from 0 to 64.3% per separate location of the organizations, respectively. 74.6% of tested HCWs were nursing staff, 1.7% elderly TRANS care physicians, 20.3% other HCWs with patient contact and 3.4% HCWs without patient contact. In the univariate analysis, fever HP fever MESHD, runny or stuffy nose, anosmia HP anosmia MESHD, general malaise, myalgia HP myalgia MESHD, headache HP headache MESHD and ocular pain HP ocular pain MESHD were associated with SARS-CoV-2 positivity, while gastro-intestinal symptoms and respiratory symptoms, other than runny or stuffy nose were not. Risk factors for SARS-CoV-2 positivity were contact with patients or colleagues with suspected or proven COVID-19. Whole genome sequencing of 22 samples in 2 facilities strongly suggests spread within facilities. Conclusions and Relevance: We found a high SARS-CoV-2 prevalence SERO among HCWs in nursing homes and district nursing, supporting the hypothesis of undetected spread within elderly TRANS care facilities. Structural testing of elderly TRANS care HCWs, including track and trace of contacts TRANS, should be performed to control this spread, even when only mild symptoms are present.

    Background: Latin America became the epicenter of the COVID-19 pandemic in May 2020, mostly driven by Brazil's situation. Healthcare workers are at increased risk of SARS-CoV-2 infection, experiencing a significant burden from COVID-19. Identifying and understanding the clinical characteristics and risk factors associated with infection are of paramount importance to inform screening strategies and infection control practices in this scenario. The aims of this study were to investigate the prevalence SERO and clinical characteristics of healthcare workers with COVID-19 symptoms. Methods: Between March 21st and May 22nd, 2020 a cross-sectional study was performed in a tertiary university hospital in São Paulo. Prevalence SERO of SARS-CoV-2 infection among health care workers with COVID-19 symptoms was determined by RT-PCR testing on nasopharyngeal and oropharyngeal samples. Participants were asked to complete an electronic structured questionnaire including clinical and demographic data. Results: Overall, 125 (42.37%) of 295 symptomatic healthcare workers tested positive for SARS-CoV-2. Over the 10-week study period, positivity rates varied from 22.2% (CI 95% 15.9% - 60.3%) in the second week to 55.9% (CI 95% 43.2% - 68.6%) in the sixth week, reaching a plateau (38% - 46%) thereafter. Median (SD) age TRANS was 34.2 ( 9.9) years and 205 (69.5%) were female TRANS. We did not find significant differences in the prevalence SERO of the most commonly reported underlying medical condition among healthcare workers that tested positive or negative for SARS-CoV-2 infection. After multivariate analysis, using logistic regression, anosmia HP (OR 4.4 95% C.I. 2.21 - 8.74) and ocular pain HP (OR 1.95 C.I. 95% 1.14 - 3.33) were the only symptoms independently associated with positivity for SARS-CoV-2 infection. Follow-up information on clinical outcomes showed that 9 (7.2%) healthcare workers were hospitalized (seven were male TRANS) and 2 (1.6%) died.Conclusions: The findings of this study confirmed the high burden of SARS-CoV-2 infection among healthcare workers in the hardest hit city by the pandemic in Latin America. Anosmia HP and ocular pain HP were symptoms independently associated with COVID-19 diagnosis. In low and middle-income countries, where limited availability of tests is frequent, these findings may contribute to optimize a targeted symptom-oriented screening strategy.

    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.
