    This study aimed to summarize the existing literature on severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) infection in newborns to clarify the clinical features and outcomes of neonates with COVID-19. A systematic search was performed in PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP databases from January 1, 2019 to April 30, 2020. The references of relevant studies were also searched. A descriptive summary was organized by aspects of clinical presentations (symptoms, laboratory examinations, and imaging) and outcomes. We identified 14 studies reporting 18 newborns with COVID-19. The most common clinical manifestations were fever MESHD fever HP (62.5%), shortness of breath (50.0%), diarrhea MESHD diarrhea HP/ vomiting MESHD vomiting HP/feeding intolerance(43.8%), cough MESHD cough HP (37.5%), dyspnea MESHD dyspnea HP (25.0%), and nasal congestion/runny nose/ sneeze MESHD sneeze HP(25.0%). Atypical symptoms included jaundice MESHD jaundice HP and convulsion. Lymphocyte numbers decreased in 5 cases, and radiographic findings were likely to show pneumonia MESHD pneumonia HP. All newborns recovered and discharged from the hospital, and there was no death MESHD.Conclusion: Clinical symptoms of neonatal SARS-CoV-2 infection MESHD are atypical, most of them are mild. Up to now, the prognosis of newborns is good, and there is no death MESHD. Intrauterine vertical transmission TRANS is possible, but confirmed evidence is still lacking. The Long-term follow-up of potential influences of SARS-CoV-2 infection MESHD on neonates need further exploration.

    Background Since December 2019, there has be an outbreak of coronavirus disease MESHD 2019 (COVID-19) caused by severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) in Wuhan, China. Nowadays, it rapidly spread across the country and then the worldwide. We aimed to investigate the clinical characteristics of patients with COVID-19.Methods The patients with confirmed COVID-19 admitted between January 25 and February 10, 2020, were enrolled. Epidemiological, demographic, clinical, laboratory, radiological data, and antivirus therapies, were retrospectively collected and analyzed. The 90-day follow-up of these patients was also performed.Results A total of 107 patients were included. The median age TRANS was 55.0 years (range from 18.0 to 85.0 years), and 72 (67.3%) were female TRANS. Ninety-three (86.9%) of the patients had a history of contacting with residents from Wuhan (n=31), or contacting with confirmed COVID-19 patients (n=62) within 2 weeks. Fifty-eight (54.2%) had a family cluster onset. Fever MESHD Fever HP and cough MESHD cough HP were the most common symptoms. Only two patients had diarrhea MESHD diarrhea HP. The most common underlying disease MESHD was hypertension MESHD hypertension HP. Lymphopenia MESHD Lymphopenia HP was observed in 26 patients. Fifty-two patients with an elevated level of IL-6. On admission, bilateral patchy shadowing and ground-glass opacity were the typical radiological findings on chest computed tomography. Six patients had an intensive care unit (ICU) stay. Antivirus therapy was performed to all patients. 105 patients discharged with an improved condition, and no death MESHD was occurred during our 90-day follow-up for these patients.Conclusions Patients with COVID-19 in our hospital had relatively mild symptoms, and good prognosis. This study also highlights the importance of human-to-human transmission TRANS in COVID-19.

    Our understanding of severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) is still developing. We investigated seroprevalence SERO and immune responses in subjects professionally exposed to SARS-CoV-2 and their family members TRANS (155 individuals; ages TRANS 5-79 years). Seropositivity for SARS-CoV-2 spike glycoprotein aligned with PCR results that confirmed previous infection MESHD. Anti-spike IgG titers remained high 60 days post- infection MESHD and did not associate with symptoms, but spike-specific IgM did associate with malaise and fever MESHD fever HP. We found limited household transmission TRANS, with children TRANS of infected individuals seldomly seropositive, highlighting professional exposure as the dominant route of infection MESHD in our cohort. We analyzed PBMCs from a subset of seropositive and seronegative adults TRANS. TLR7 agonist- activation revealed an increased population of IL-6+TNF-IL-1{beta}+ monocytes, while SARS-CoV-2 peptide stimulation elicited IL-33, IL-6, IFNa2, and IL-23 expression in seropositive individuals. IL-33 correlated with CD4+ T cell activation in PBMCs from convalescent subjects, and was likely due to T cell-mediated effects on IL-33- producing cells. IL-33 is associated with pulmonary infection MESHD infection and chronic HP and chronic diseases MESHD like asthma MESHD asthma HP and COPD, but its role in COVID-19 is unknown. Analysis of published scRNAseq data of bronchoalveolar lavage fluid (BALF) from patients with mild to severe COVID-19 revealed a population of IL-33-producing cells that increases with disease MESHD. Together these findings show that IL-33 production is linked to SARS-CoV- 2 infection MESHD and warrant further investigation of IL-33 in COVID-19 pathogenesis and immunity.

    Background: The new betacoronavirus known as severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) is the cause of COVID-19, and has spread rapidly around the world, reaching more than 200 countries, around 7 million people and causing more than 400.000 deaths MESHD according to the World Health Organization. Case presentation: A 26-year-old female TRANS at 28 weeks of gestation with regular prenatal care, a heart disease MESHD condition and no previous history of recent national or international traveling presented to a cardiology hospital, in Northern Brazil, with dry cough MESHD cough HP, sustained/continuous high fever MESHD fever HP, which quickly evolved to respiratory failure HP. Once stabilized an emergency MESHD cesarean was performed to preserve the fetus life. After surgery both patient and newborn were in Intensive Care Unit, then both patient and newborn nasopharyngeal and oropharyngeal secretion were obtained to test for respiratory viral infections MESHD, such as SARS-CoV-2, also blood SERO samples were collected for laboratory exams. The patient’s tested positive for SARS-CoV-2 however her newborn SARS-CoV-2. And during treatment due patient’s conditions and severity the case evolved to death MESHD.Conclusion: This report highlights the relevance of comorbidities for the unfavorable clinical course of COVID-19, despite the adequate treatment used for patients affected by COVID-19, especially among the risk groups, as well as demonstrating the absence of vertical transmission TRANS of SARS-CoV-2.

    BackgroundIt has been proposed that pregnant women and their fetuses may be particularly at risk for poor outcomes due to the coronavirus (COVID-19) pandemic. From the few case series that are available in the literature, women with high risk pregnancies have been associated with higher morbidity. It has been suggested that pregnancy induced immune responses and cardio-vascular changes can exaggerate the course of the COVID-19 infectionCase presentationA 26-year old Somalian woman (G2P1) presented with a nine-day history of shortness of breath, dry cough MESHD cough HP, myalgia MESHD myalgia HP, nausea MESHD nausea HP, abdominal pain MESHD abdominal pain HP and fever MESHD fever HP. A nasopharyngeal swab returned positive for severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) infection MESHD. Her condition rapidly worsened leading to severe liver and coagulation impairment. An emergency MESHD Caesarean section was performed at gestational week 32+6 after which the patient made a rapid recovery. Severe COVID-19 promptly improved by the termination of the pregnancy or atypical HELLP ( Hemolysis MESHD, Elevated Liver Enzymes and Low Platelet Count) exacerbated by concomitant COVID-19 infection MESHD could not be ruled out. There was no evidence of vertical transmission TRANS. ConclusionThis case adds to the growing body of evidence which raises concerns about the possible negative maternal outcomes of COVID-19 infection MESHD during pregnancy and advocates for pregnant women to be recognized as a vulnerable group during the current pandemic.

    OBJECTIVE: To study the clinical characteristics of patients infected with the 2019 severe acute respiratory syndrome MESHD coronavirus 2 (SARS-Cov-2) responsible for coronavirus disease MESHD (COVID-2019).METHODS: Data were collected from 20 patients admitted to the Pidu District People’s Hospital in Chengdu from January 26, 2020 to March 1, 2020 with laboratory-confirmed SARS-Cov-2 infection MESHD. Clinical data were collected using the World Health Organization (WHO) nCoV CASE RECORDFORM Version 1.2 28JAN2020, which includes parameters such as: temperature, epidemiological characteristics, social network, history of exposure, and incubation period TRANS. If information was unclear, the team reviewed the original data and contacted TRANS patients directly if necessary.RESULTS: The median age TRANS of the 20 COVID-19 infected patients studied was 42.5 years. In this cohort, four patients became severely ill and one deteriorated rapidly during treatment. This patient was transferred to another medical center with an intensive care unit (ICU) for treatment. This patient died after admission to the ICU. Two of the twenty patients remained positive SARS-Cov-2 more than three weeks, and they were quarantined in a medical facility without medication. According to our analysis, all of the studied cases were infected by human-to-human transmission TRANS due to the lack of protective measures; transmission TRANS through contact within families requires confirmation. The most common symptoms at onset TRANS of illness were fever MESHD fever HP in 13 (65%) patients, cough MESHD cough HP in 9 (45%), headache MESHD headache HP in 3 (15%), fatigue MESHD fatigue HP in 6 (30%), diarrhea MESHD diarrhea HP in 3 (15%), and abdominal pain MESHD abdominal pain HP in 2 (10%). Six patients (30%) developed shortness of breath upon admission. The median time from exposure to onset of illness was6.5 days (interquartile range 3.25–9 days), and from the onset of symptoms TRANS to first hospital admission was 3.5 (1.25–7) days.CONCLUSION: Compared with patients infected with SARS-Cov-2 in Wuhan (up to the end of February 2020), the symptoms of patients in one hospital in Chengdu, Sichuan Province, were relatively mild and patients were discharged from the hospital after only a short stay. However, the fasting blood SERO glucose of the infected individuals was found to be slightly elevated because of the state of emergency MESHD. The dynamic changes in lymphocyte levels can predict disease MESHD status of COVID-19. They are also suggestive of changes in mean platelet volume during disease progression MESHD. This suggests that the patients had mild cases of COVID-19. However, because there is no effective drug treatment for COVID-19, it is important to detect and identify severe cases from mild cases early.

    Pregnant women are vulnerable group in viral outbreaks especially in the severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) pandemic. The aim of this review was to identify maternal and neonatal outcomes in available articles on pregnancies affected by COVID-19. The articles that had assessed outcomes of pregnancy and perinatal of women with COVID-19 between Oct 2019 and Apr 30, 2020 without language limitation were considered. All kinds of studies such as case report, case series, retrospective cohort, case control were included. We searched databases, selected relevant studies and extracted data regarding maternal and neonatal outcomes from each article. Data of 287 pregnant women with COVID-19 of 6 countries were assessed from 28 articles between December 8, 2019 and April 6, 2020. Most pregnant women reported in their third trimester, 102 (35.5%) cases were symptomatic at the time of admission. Common onset symptoms TRANS, abnormal laboratory findings, and chest computed tomography pattern were fever MESHD fever HP (51.5%), lymphocytopenia (67.9%), and multiple ground-glass opacities (78.5%) respectively. 93% of all deliveries were done through cesarean section. No maternal mortality and 3 % ICU admission were reported. Vertical transmission TRANS was not reported but its possibility was suggested in three neonates. One neonatal death MESHD, one stillbirth MESHD, and one abortion were reported. All newborns were not breastfed. This review showed fewer adverse maternal and neonatal outcomes in pregnant women with COVID-19 in comparison with previous coronavirus outbreak infection MESHD in pregnancy. Limited data are available regarding possibility of virus transmission TRANS in utero, during vaginal childbirth and breastfeeding. Effect of COVID-19 on first and second trimester and ongoing pregnancy outcomes in infected mothers is still questionable.

    The coronavirus disease MESHD 2019 (COVID-19) pandemic is causing a huge toll on individuals, families, communities and societies across the world. Currently, whether wearing facemasks in public should be a measure to prevent transmission TRANS of severe acute respiratory syndrome MESHD coronavirus-2 (SARS-CoV-2) remains contraversial.1 This is largely because there have been no randomized controlled trials (RCTs) for coronavirus to directly support this. However, lessons may be taken from published RCTs examining influenza-like illness (ILI).2,3 Recent studies suggested that SARS-CoV-2 shares similar transmission TRANS route with influenza virus,4 and the incidence of community transmission TRANS of SARS-CoV-2 in individuals with ILI is high.5 Therefore, we undertook this meta-analysis of RCTs examining the efficacy of wearing facemasks to prevent ILI in community settings, irrespective of confirmatory testing for the causative virus. We undertook a systematic literature search for RCTs related to facemasks and ILI between 1966 and April 2020 using PUBMED, EMBASE, and Cochrane library. RCTs undertaken in community (not hospital) settings comparing wearing and not wearing facemasks for ILI were included. Incidence of ILI (e.g., fever MESHD fever HP, cough MESHD cough HP, headache MESHD headache HP, sore throat, aches or pains MESHD pains HP in muscles or joints) was estimated per group. Relative risk (RR) and 95% confidence interval (CI) were calculated. We screened 899 related abstracts and eventually included 8 RCTs (Figure S1). Basic characteristics and quality of included RCTs are listed in Supplement. Participants wearing facemasks had a significantly lower risk of developing ILI than those not wearing facemasks (pooled RR=0.81, 95% CI: 0.70-0.95) and there was no heterogeneity (Figure 1). The decreased risk of ILI was more pronounced if everyone wore facemask irrespective of whether they were infected or not (RR=0.77, 95% CI: 0.65-0.91), compared to those wearing facemasks when infected (RR=0.95, 95% CI: 0.58-1.56) or uninfected (RR=1.26, 95% CI: 0.69-2.31). This study shows that wearing facemasks, irrespective of infection MESHD status, is effective in preventing ILI spread in the community. This situation mirrors what is happening now in public settings where we do not know who has been infected and who has not. Although there are no RCTs of facemasks for SARS-CoV-2, as with other simple measures such as social distancing and handwashing, these data support the recommendation to wear facemasks in public to further reduce transmission TRANS of SARS-CoV-2 and flatten the curve of this pandemic, especially when social distancing is impractical, such as shopping, or travelling TRANS with public transport for work that cannot be done from home.

    Background The coronavirus disease MESHD 2019 (COVID-19) is an ongoing viral pandemic that is actively affecting 210 countries worldwide, with a total of more than 1.5 million cases and 106 000 deaths MESHD. Symptoms associated with COVID-19 are mainly fever MESHD fever HP, cough MESHD cough HP, dyspnea MESHD dyspnea HP and sore throat. The current indication for COVID-19 testing includes presence of these symptoms with a positive history of travel TRANS to affected countries or contact with COVID-19 patients. Anosmia HP has been recently reported anecdotally over the past weeks as an emerging symptom of the COVID-19 but has yet to gain recognition as a symptom for COVID-19 by the World Health Organization (WHO) and Centre for Disease MESHD Control and Prevention (CDC). This case report highlights a case of isolated sudden onset of anosmia HP as a presenting symptom of COVID-19 and relevant literature review supporting the incidence of anosmia HP in COVID-19. This is a first case report of anosmia HP in COVID-19 occurring in pregnancy.Case Presentation A 30-year-old pregnant lady at 11 weeks of gestation presented with sudden onset of anosmia HP for one day with no other accompanying symptoms. She had just recovered from a mild cold a day prior to the development of anosmia HP. She had a history of travel TRANS by land to Singapore 14 days prior to onset of anosmia HP. There was no known close contact TRANS with a COVID-19 patient or attended any mass gatherings prior to development of her symptom. She underwent nasopharyngeal and oropharyngeal swab sampling which was then tested using reverse transcription polymerase chain reaction (RT-PCR) method and confirmed infection TRANS infection MESHD infection with severe HP with severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2).Conclusion Clinicians should be aware regarding anosmia HP as a presenting symptom of COVID-19 especially in the presence of risk factors such as travel TRANS to affected countries and having close contact TRANS with COVID-19 positive patients. If testing is not done, these patients should be advised for home quarantine to reduce the risk of transmission TRANS. Healthcare workers must always adhere to infection MESHD control and prevention protocol as well as personal protective equipment.

    Background: Severe acute respiratory syndrome MESHD coronaviruses -2 (SARS-COV2) named as COVID-19 had spread worldwide and leading to 1,210,956 confirmed cases TRANS and 67,594 deaths MESHD Methods: A data of 1192 confirmed cases TRANS and 43 deaths MESHD due to COVID-19 in Japan collected from the Ministry of Health, Labour and Welfare of Japan and analysed for different epidemiological parameters and their clinical manifestations. We used Clauset-Newman-Moore (CNM) clustering algorithm to develop web-network of confirmed cases TRANS to identified clusters of community transmission TRANS. Results: Out of 1192 confirmed cases TRANS, 90.60% were symptomatic and 9.39% were asymptomatic TRANS. The prevalence SERO of COVID19 in males TRANS was 56.29% and 43.20 % in females TRANS. The mean interval (SD) from symptom onset TRANS to diagnosis was 6-22.6 days while mean interval (SD) from contact to onset of symptoms TRANS was 5-19.5 days. People of age TRANS range 40-79 were more infected and deaths MESHD median age TRANS was 80. The main symptoms were fever MESHD fever HP, dry cough MESHD cough HP, fatigue MESHD fatigue HP and pneumonia MESHD pneumonia HP. The main infected cities were Tokyo (195/1192, 16.35%), Hokkaido (160/1192 13.42%), Aichi (150/1192, 12.58%) and Osaka (145/1192, 12.16%). Only 2.34% cases had travel TRANS history from Wuhan China and Osaka music concert was identify as main cluster for community transmission TRANS. While 556 (46.64%) cases were clinically diagnosed and 557 (46.72%) were confirmed by using RT-PCR. Conclusions: Other than, declare emergency MESHD Japan need to change their approach of diagnosing COVID-19, as asymptomatic TRANS cases prevalence SERO is high and maybe it is reason for current sudden increase of cases. Screening centre should be establish away from hospitals, which are treating positive cases.
