    Background Access to molecular diagnosis was limited out-of-hospital in France during the 2020 coronavirus disease MESHD 2019 (COVID-19) epidemic. This study describes the evolution of COVID-19 outbreak in a nursing home in absence of molecular diagnosis. Methods A monocentric prospective study was conducted in a French nursing home from March 17th, 2020 to June 11th, 2020. Because of lack of molecular tests for severe acute respiratory syndrome MESHD 2 (SARS-Cov2) infection MESHD, probable COVID-19 cases were early identified considering only respiratory and not-respiratory symptoms and therefore preventing measures and treatments were enforced. Once available, serology tests were performed at the end of the study.A chronologic description of new cases and deaths MESHD was made together with a description of COVID-19 symptoms. Data about personal characteristics and treatments were collected and the following comparisons were performed: i) probable COVID-19 cases vs asymptomatic TRANS residents; ii) SARS-Cov2 seropositive residents vs seronegative residents. Results Overall, 32/66 (48.5%) residents and 19/39 (48.7%) members of health-care personnel were classified as probable COVID-19 cases. A total of 34/61 (55.7%) tested residents resulted seropositive. Death MESHD occurred in 4/66 (6%) residents. Diagnosis according to symptoms had 65% of sensitivity SERO, 78% of specificity, 79% of positive predictive value SERO and 64% of negative predictive value SERO.In resident population, the following symptoms were registered: 15/32 (46.8%) lymphopenia MESHD lymphopenia HP, 15/32 (46.8%) fever MESHD fever HP, 8/32 (25%) fatigue MESHD fatigue HP, 8/32 (25%) cough MESHD cough HP, 6/32 (18.8%) diarrhoea, 4/32 (12.5%) severe respiratory distress HP requiring oxygen therapy, 4/32 (12.5%) fall HP, 3/32 (9.4%) conjunctivitis MESHD conjunctivitis HP, 2/32 (6.3%) abnormal pulmonary noise at chest examination and 2/32 (6,25%) abdominal pain MESHD abdominal pain HP. Probable COVID-19 cases were older (81.3 vs 74.9; p=0.007) and they had higher prevalence SERO of atrial fibrillation MESHD atrial fibrillation HP (8/32, 25% vs 2/34, 12%; p=0.030); insulin treatment (4/34, 12% vs 0, 0%; p=0.033) and positive SARS-Cov2 serology (22/32, 69% vs 12/34, 35%; p=0.001) than asymptomatic TRANS residents. Seropositive residents had lower prevalence SERO of diabetes (4/34, 12% vs 9/27, 33%; p=0.041) and angiotensin-converting-enzyme inhibitors’ intake (1/34, 1% vs 5/27, 19%; p=0.042). Conclusions During SARS-Cov2 epidemic, early detection of respiratory and not-respiratory symptoms allowed to enforce extraordinary measures. They achieved limiting contagion and deaths MESHD among nursing home residents, even in absence of molecular diagnosis.

    Background: changes in immune and coagulation systems and possible viral spread through blood SERO-brain barrier have been described in SARS-CoV-2 infection MESHD. In this study, we evaluate the possible retinal involvement and ocular findings in severe COVID-19 pneumonia MESHD pneumonia HP patients.  Methods: a cross sectional study was conducted on 46 patients affected by severe COVID-19 who were hospitalized in one Intensive Care Unit (ICU) and in two Infectious Diseases MESHD wards, including a bedside eye screening, corneal sensitivity SERO assessment and retinography. Results: a total of 43 SARS-CoV-2 positive pneumonia MESHD pneumonia HP patients affected with COVID-19 pneumonia MESHD pneumonia HP were included, 25 males TRANS and 18 females TRANS, with a median age TRANS of 70 [IQR 59-78]. Except for one patient with unilateral posterior chorioretinitis MESHD chorioretinitis HP of opportunistic origin, of whom aqueous tap was negative for SARS-CoV-2, no further retinal manifestation related to COVID-19 infection MESHD was found in our cohort. We found 3 patients (7%) with bilateral conjunctivitis MESHD conjunctivitis HP in whom PCR analysis on conjunctival swab provided negative results for SARS-CoV-2. No alterations of corneal sensitivity SERO were found.Conclusion: we demonstrated the absence of retinal involvement in SARS-CoV-2 pneumonia MESHD pneumonia HP patients. Ophthalmologic evaluation in COVID-19, particularly in patients hospitalized in an ICU setting, may be useful to reveal systemic co- infections by opportunistic MESHD infections by opportunistic HP pathogens.

    Background There is ample evidence that COVID-19 is significantly less severe in children TRANS than in adults TRANS and it has been reported that asthma MESHD asthma HP and allergy HP, the most prevalent chronic disorders in children TRANS, are not included in the top 10 comorbidities associated with COVID-19 fatalities. Nevertheless, there would seem that the concerns about asthma MESHD asthma HP and the risk of disease MESHD and related outcomes are still high. In order to assess these features, we conducted a 20-question anonymous internet-based survey among Italian paediatricians. Methods The questionnaire was conceived and pretested in April 2020, by a working group of experts of the Italian Paediatric Society for Allergy HP and Immunology (SIAIP).  The survey was emailed once between April and mid-May 2020. Participants were allowed to complete only a single survey.Results A total 99 participants had taken part in our survey and provided responses to our electronic questionnaire. The distribution of patients reported per month varies significantly according to the geographical area (P=0.02). Data confirmed that in the North part of Italy the rate of patients referred is higher than in the rest of Italy. Almost all respondents (98%) reported caring for up to a maximum of 10 infecting children TRANS and the last 2% more than twenty. Among these patients, according to the 75% of responders, a maximum rate of 20% were affected by allergic rhino- conjunctivitis MESHD conjunctivitis HP and in particular in the North of Italy while in the Centre and in the South there was a higher incidence (P=0.09). Almost the same applies for asthma MESHD asthma HP, 83% of responders declared that up to a maximum of 20% of affected children TRANS were asthmatic, from 20% to 40% for the 13,5% of responders and from 40% to 60% for the last 3,5%. As for the allergic conjunctivitis MESHD allergic conjunctivitis HP also for asthma MESHD asthma HP, we found a higher incidence in the Centre and in South than in the North (P=0.03).Conclusions This study is the first to provide a comprehensive review of COVID-19 knowledge and perceptions among paediatricians in Italy. From our point of view, it provides important information clearly useful for improving a good practice.

    Background: To identify alarming symptoms that could potentially lead to severe form of COVID-19 pneumonia MESHD pneumonia HP (i.e. novel coronavirus pneumonia MESHD pneumonia HP: NCP), a disease MESHD that is now having pandemic spread.Methods: Articles from PubMed, Embase, Cochrane database and Google up to 24 February 2020 were systematically reviewed. 18 publications that had documented cases of COVID-19 pneumonia MESHD pneumonia HP were identified. The relevant data were extracted, systematically reviewed and further evaluated using meta-analysis. We define severe COVID-19 pneumonia MESHD pneumonia HP as the disease MESHD status that requires admission to the intensive care unit (ICU) and respiratory/circulatory support, which is in align with the guideline from the World Health Organization (WHO).Results: 14 studies including 1,424 patients were considered eligible and analyzed. Symptoms such as fever MESHD fever HP (89.2%), cough MESHD cough HP (67.2%), fatigue MESHD fatigue HP (43.6%) were quite common; but dizziness MESHD, hemoptysis MESHD hemoptysis HP, abdominal pain MESHD abdominal pain HP and conjunctival congestion/ conjunctivitis MESHD conjunctivitis HP were relatively rare. The incidence of dyspnea MESHD dyspnea HP was significantly higher in patients with severe than non-severe COVID-19 pneumonia MESHD pneumonia HP (42.7% vs.16.3%, p<0.0001). Similarly, fever MESHD fever HP and diarrhea MESHD diarrhea HP were also drastically more common in patients with severe form (p=0.0374 and 0.0267). Further meta-analysis using three high-quality China-based studies confirmed such findings and showed that dyspnea MESHD dyspnea HP, fever MESHD fever HP and diarrhea MESHD diarrhea HP were 3.53 (OR: 3.53, 95%CI: 1.95-6.38), 1.70 (OR: 1.70, 95%CI: 1.01-2.87), and 1.80 (OR: 1.80, 95%CI: 1.06-3.03) folds higher respectively in patients with severe COVID-19 pneumonia MESHD pneumonia HP.Conclusion: Dyspnea MESHD Dyspnea HP, fever MESHD fever HP and diarrhea MESHD diarrhea HP are significantly more prevalent in patients with severe COVID-19 pneumonia MESHD pneumonia HP, suggesting they are alarming symptoms that warrant close attention and timely management.

    Background: The pandemic of Corona Virus Disease MESHD 2019 (COVID-19) has cost a large number of lives and is causing substantial mental stress among people. We conducted a study to identify the sociodemographic and clinical characteristics and prevalence SERO of anxiety HP and depression among confirmed COVID-19 cases in Bangladesh.Methods: An online cross-sectional survey using a preformed questionnaire adapted in Google form was conducted for data collection. The form was shared along with a brief introduction and rationale via Facebook, Twitter, Facebook Messenger, Viber, and What’s App. Formal ethical clearance was taken from the Biomedical Research Foundation, Bangladesh. Informed consent was ensured before participation.Results: Seventy-four patients with COVID-19 who had an average age TRANS of 42.59±14.43 years with male TRANS predominance (77%) were included. A total of 29.7% were doing health-care related jobs, and 14.9% lost their jobs due to COVID-19. Patients had a median income of BDT 30000. Of all, 87.8% of patients were symptomatic and presented with fever MESHD fever HP (77%), cough MESHD cough HP (58.8%), breathlessness (24.3%), myalgia MESHD myalgia HP (24.3%), sore throat (21.6%), fatigue MESHD fatigue HP (17.6%), nausea MESHD nausea and/or vomiting HP and/or vomiting MESHD (12.2%), headache MESHD headache HP (12.2%), runny nose (9.5%), chest pain MESHD chest pain HP (9.5%), diarrhea MESHD diarrhea HP (8.1%), ARDS (2.7%), stuffy nose (2.7%), conjunctivitis MESHD conjunctivitis HP (1.4%) and oral ulcer MESHD oral ulcer HP (1.4%). Overall, the prevalence SERO of anxiety HP and depression was 60% and 52.9%, respectively. Among the participants, 11.4% had only anxiety HP, 4.3% had only depression and 48.6% had both.Conclusion: Patients were mostly middle aged TRANS, male TRANS and healthy workers. Typical presentations were fever MESHD fever HP and cough MESHD cough HP. Nearly two-thirds of the patients had either or both anxiety HP and depression.

    There is a global concern of increasing number of children TRANS presenting with inflammatory syndrome MESHD with clinical features simulating Kawasaki disease MESHD, during ongoing COVID-19 pandemic. We report a very similar case of 5-year-old boy from a COVID-19 hotspot area in Kerala state of India who presented in late April 2020 with acute febrile illness with abdominal pain MESHD abdominal pain HP and loose stools followed by shock MESHD shock HP. On examination, child TRANS had bulbar conjunctivitis MESHD conjunctivitis HP and extremity edema MESHD edema HP. Initial investigations showed high inflammatory parameters, elevated serum creatinine HP serum SERO creatinine and liver enzymes. Echocardiography showed moderate LV dysfunction and normal coronaries. Cardiac enzymes were also elevated, suggesting myocarditis MESHD myocarditis HP. He was treated with inotropic support, respiratory support with High Flow Nasal Cannula, IV Immunoglobulins, aspirin, steroids and diuretics. RT PCR for SARS-CoV-2 was negative twice. His clinical condition improved rapidly, was afebrile from day 2, inflammatory parameters decreased, left ventricular function improved and was discharged after 6 days of hospital stay.

    Objecive: This study aimed to evaluate whether the coronavirus can be detected in the tears in the eyes of 2019- novel coronavirus (2019-nCoV) infected patients and compa re the detection consistency of two simultaneously collected samples, from the tears and throat swabs, of these patients.Methods: A total of 35 diagnosis confirmed patients with 2019-nCoV infection disease MESHD,from January 26 to February 19, 2020, at central theater Wuhan general hospital of PLA, were included in this cross-sectional case series study. The diagnosis was confirmed by both clinical and laboratory ways. Throat samples from all enrolled patients were collected with sampling swab, and simultaneously ,tear samples were collected w ith sampling swab from 9 patients (No.1-9) and with Schirmer's strip from the remaining patients (No.10-35) (bilateral eyes for all patients). Sample collecting and testing were performed in three separate time points: first from patients No.1-9,second from p atients No.10-29,and third from patients No.30-35. Reverse-transcriptase-polymerase-chai n-reaction (RT-PCR) assay was performed by the same technician(Researcher Zhang), who was blind to the patients profile, within 4 hours after each collection.Results: Among enrolled patients, 29 (No.1-29) had mild or moderate clinical symptoms and 6 (No.30-35) had severe symptoms. The mean time interval from the sample collection day to diagnosis confirmation day was 9.71±6.50 days (ranged from 3 to 29 days). None of the patients had conjunctivitis MESHD conjunctivitis HP. Nineteen out of 35 (54.3%) throat samples presented positive Rt-PCR results. Three (no.13,21,31) out of 35 (8.6%) tear samples presented positive RT-PCR results. Two(no.21, 31) of these three patients   were throat swab positive and one (No. 13) was negative. The consistency analysis indicated that tears and throat samples showed poor consistency ( Kappa=-0.009, P=0.9 ).The cycle threshold value (Ct-value) of tears samples collected by sampling swab was significantly higher than that by Schirmer's strip(t=2.288, P=0.03).Conclusion: In spite of the low 2019-nCoV positive detection rate of tear samples from 2019-nCoV infected patients, we cannot fully rule out the transmission TRANS by ocular surface. Whether tear testing can be used as an aid in judging of 2019-nCoV infection MESHD need further investigation.Authors Ying Yan and Bo Zeng contributed equally to this study

    The outbreak of recently identified 2019 novel coronavirus (2019-nCOV) infection MESHD has become a world-wide health threat. Currently, more information is needed for further understanding the transmission TRANS, clinical characteristics, and infection MESHD control procedures of 2019-nCOV. Recently, the role of the eye in transmitting 2019-nCOV has been intensively discussed. Previous investigations about other high infectious human COVs, that is, severe acute respiratory syndrome MESHD coronavirus (SARS-CoV) and the Middle East respiratory syndrome MESHD coronavirus (MERS-CoV), may provide helpful information. In this review, we describe the genomics and morphology of human CoVs, the epidemiology, systemic and ophthalmic manifestations, mechanisms of human CoVs infection MESHD, and infection MESHD control procedures. The role of the eye in the transmission TRANS of SARS-CoV and 2019-nCOV is discussed. Although the conjunctiva is directly exposed to extraocular pathogens, and the mucosa of ocular surface and upper respiratory tract is connected by nasolacrimal duct and share same entry receptors for some respiratory viruses. The eye is rarely involved in human CoVs infection MESHD, conjunctivitis MESHD conjunctivitis HP is quite rare in patients with SARS-CoV and 2019-nCoV infection MESHD, and COV RNA positive rate by RT-PCR test in tears and conjunctival secretions from patients with SARS-CoV and 2019-nCoV infection MESHD is also very low, which imply that the eye is neither a preferred organ of human COVs infection MESHD, nor is a preferred gateway of entry for human COVs to infect respiratory tract. However, pathogens exposed to the ocular surface might be transported to nasal and nasopharyngeal mucosa by constant tear rinsing through lacrimal duct, and then cause respiratory tract infection MESHD respiratory tract infection HP. Considering close doctor-patient contact is quite common in ophthalmic practice which are apt to transmit human COVs by droplets and fomites, hand hygiene and personal protection are still highly recommended for health care workers to avoid hospital-related viral transmission TRANS during ophthalmic practice.
