    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.

    Coronaviruses are enveloped viruses that can cause respiratory, gastrointestinal, hepatic, and neurological diseases MESHD. In December 2019, a new highly contagious coronavirus termed severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) emerged in China. SARS-CoV-2 causes a potentially lethal human respiratory infection MESHD, COVID-19, that is associated with fever MESHD fever HP and cough MESHD cough HP and can progress to pneumonia MESHD pneumonia HP and dyspnea MESHD dyspnea HP in severe cases. Since the virus emerged, it has spread rapidly, reaching all continents around the world. A previous study has shown that, despite being the best alternative in the current pandemic context, social distancing measures alone may not be sufficient to prevent COVID-19 spread, and the overall impact of the virus is of great concern. The present study aims to describe the demographic and socioeconomic characteristics of 672 cities with cases of COVID-19, as well as to determine a predictive model for the number of cases. We analyzed data from cities with at least 1 reported case of COVID-19 until June 26, 2020. It was observed that cities with confirmed cases TRANS of the disease MESHD are present in all Brazilian states, affecting 36.5% of the municipalities in Rio de Janeiro State. The inhabitants in cities with reported cases of COVID-19 represent more than 73.1% of the Brazilian population. Stratifying the age groups TRANS of the inhabitants and accounting for the percentage of women and men does not affect COVID-19 incidence ( confirmed cases TRANS/100,000 inhabitants). The demographic density, the MHDI and the per capita income of the municipalities with cases of COVID-19 do not affect disease MESHD incidence. In addition, if conditions are maintained, our model predicts 2,358,703 (2,172,930 to 2,544,477) cumulative cases on July 25, 2020.

    The newly identified severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) causes COVID-19, a pandemic respiratory disease MESHD presenting with fever MESHD fever HP, cough MESHD cough HP, and often pneumonia MESHD pneumonia HP. Moreover, thromboembolic events throughout the body including the central nervous system (CNS) have been described. Given first indication for viral RNA presence in the brain and cerebrospinal fluid and in light of neurological symptoms in a large majority of COVID-19 patients, SARS-CoV-2-penetrance of the CNS is likely. By precisely investigating and anatomically mapping oro- and pharyngeal regions and brains of 32 patients dying from COVID-19, we not only describe CNS infarction due to cerebral MESHD thromboembolism MESHD thromboembolism HP, but also demonstrate SARS-CoV-2 neurotropism. SARS-CoV-2 enters the nervous system via trespassing the neuro-mucosal interface in the olfactory mucosa by exploiting the close vicinity of olfactory mucosal and nervous tissue including delicate olfactory and sensitive nerve endings. Subsequently, SARS-CoV-2 follows defined neuroanatomical structures, penetrating defined neuroanatomical areas, including the primary respiratory and cardiovascular control center in the medulla oblongata.

    Background: An outbreak of severe acute respiratory syndrome MESHD due to coronavirus 2 (SARS-CoV-2) infection MESHD (COVID-19) that began at Wuhan, China in December 2019, spreading rapidly across China and many other countries. Considering the high false-negative rate of RT-PCR assay during initial COVID-19 pandemic in China, chest computed tomography (CT) was advocated as a means of corroborating clinically suspected infections MESHD.Case presentation: A 51-year-old man with clinical diagnosis of hepatic portal cholangiocarcinoma MESHD cholangiocarcinoma HP and Behcet's disease MESHD developed clinical manifestations suggestive of COVID-19 during the pandemic in China. The chest CT showed rapid progression to diffuse ground-glass opacities (GCOs) in both lungs, as in severe cases of confirmed TRANS COVID-19. He was finally diagnosed with Pneumocystis jiroveci pneumonia MESHD pneumonia HP (PJP) according to the medical history, and Caspofungin plus TMP/SMX elicited a rapid response as normalizing both temperature and leukocyte count initially. Unfortunately, dyspnea MESHD dyspnea HP was aggravated with resumed fever MESHD fever HP later, and non-invasive ventilation was no longer tenable. The patient himself (with support of his family) declined mechanical ventilatory assistance, succumbing to pneumonia MESHD pneumonia HP and respiratory failure HP finally.Conclusions: CT diagnosis of COVID-19 during the current pandemic should warrant caution.

    Backgrounds In December 2019, a pneumonia MESHD pneumonia HP associated with the severe acute respiratory syndrome MESHD coronavirus 2 (SARS-Cov-2) emerged in Wuhan city, China. As of 20 Feb 2020, a total of 2,055 medical staff infected with SARS-Cov-2 in China had been reported. The predominant cause of the infection MESHD and the failure of protection among medical staff remains unclear. We sought to explore the epidemiological, clinical characteristics and prognosis of novel coronavirus-infected medical staff.Methods Medical staff who infected with SARS-Cov-2 and admitted to Union Hospital, Wuhan between 16 Jan, 2020 to 25 Feb, 2020 were included retrospectively. Epidemiological, clinical and radiological data were compared by occupation and analyzed with the Kaplan-Meier and Cox regression methods.Results A total of 101 medical staff (32 males TRANS and 69 females TRANS; median age TRANS: 33 years old) were included in this study and 74% were nurses. None had an exposure to Huanan seafood wholesale market or wildlife. A small proportion of the cohort had contact with specimens (3%) as well as patients infected with SARS-Cov-2 in fever MESHD fever HP clinics (15%) and isolation wards (3%). 80% of medical staff showed abnormal IL-6 levels and 33% had lymphocytopenia. Chest CT mainly manifested as bilateral (62%), septal/subpleural (77%) and ground­glass opacities (48%). The major differences between doctors and nurses manifested in laboratory indicators. As of the last observed date, no patient was transferred to intensive care unit or died, and 98 (97%) had been discharged. Fever MESHD Fever HP (HR=0.57; 95% CI 0.36-0.90) and IL-6 levels greater than >2.9 pg/ml (HR=0.50; 95% CI 0.30-0.86) on admission were unfavorable factors for discharge.Conclusions Our findings suggested that the infection MESHD of medical staff mainly occurred at the early stages of SARS-CoV-2 epidemic in Wuhan, and only a small proportion of infection MESHD had an exact mode. Meanwhile, medical staff infected with COVID-19 have relatively milder symptoms and favorable clinical course than other ordinary patients, which may be partly due to their medical expertise, younger age TRANS and less underlying diseases MESHD. The potential risk factors of presence of fever MESHD fever HP and IL-6 levels greater than >2.9 pg/ml could help to identify medical staff with poor prognosis at an early stage.

    OBJECTIVE To describe the clinical characteristics and epidemiological features of severe (non-ICU) and critically patients (ICU) with COVID-19 at triage, prior hospitalization, in one of the main hospitals in The Balearic Islands health care system. DESIGN Retrospective observational study SETTING Son Llatzer University Hospital in Palma de Mallorca (Spain) PARTICIPANTS Among a cohort of 52 hospitalized patients as of 31 March 2020, 48 with complete demographic information and severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) positive test, were analyzed. Data were collected between March 15th, 2020, and March 31th 2020, inclusive of these dates. MAIN OUTCOMES Clinical, vital signs and routine laboratory outcomes at the time of hospitalization, including symptoms reported prior to hospitalization. Demographics and baseline comorbidities were also collected. Mortality was reported at the end of the study. RESULTS 48 patients (27 non-ICU and 21 ICU) resident in Mallorca, Spain (mean age TRANS, 66 years, [range, 33-88 years]; 67% males TRANS) with positive SARS-CoV-2 infection MESHD were analyzed. There were no differences in age TRANS or sex among groups (p >.05). Initial symptoms included fever MESHD fever HP (100%), coughing MESHD coughing HP (85%), dyspnea MESHD dyspnea HP (76%), diarrhea MESHD diarrhea HP (42%) and asthenia MESHD asthenia HP (21%). The majority of patients in this case series were hospitalized because of low SpO2 (SpO2 below 90%) and presentation of bilateral pneumonia MESHD pneumonia HP (94%) at triage. ICU patients had a higher prevalence SERO of dyspnea MESHD dyspnea HP compared to non-ICU patients (95% vs 61%, p = .022). Acute respiratory syndrome MESHD (ARDS) was presented in 100% of the ICU-patients. All the patients included in the study required oxygen therapy. ICU-patients had lymphopenia MESHD lymphopenia HP as well as hypoalbuminemia MESHD hypoalbuminemia HP. Inflammatory markers such as lactate dehydrogenase (LDH), C-reactive protein (CRP), and procalcitonin were significantly higher in ICU patients compared to non-ICU (p < .001).Lower albumin levels were associated with poor prognosis measured as longer hospital length (r= -0.472, p

    In India the first case of coronavirus disease MESHD 2019 (COVID-19) reported on 30 January 2020, and thereafter cases were increasing daily after the last week of Feb. 2020. COVID-19 identified as family member TRANS of coronaviridae where previously Middle East Respiratory Syndrome MESHD MERS and Severe Acute Respiratory Syndrome MESHD SARS belongs to same family. The COVID-19 attacks on respiratory system signing fever MESHD fever HP, cough MESHD cough HP and breath shortness, in severe cases may cause pneumonia MESHD pneumonia HP, SARS or some time death MESHD. The aim of this study work is to develop model which predicts the epidemic peak for COVID-19 in India by using the real-time data from 30 Jan to 10 May 2020. There are uncertainties while identifying the population information due to the incomplete and inaccurate data, we initiate the most popular model for epidemic prediction i.e Susceptible, Exposed, Infectious, & Recovered SEIR initially the compartmental model for the prediction. Based on the solution of the state estimation problem for polynomial system with Poisson noise, we estimate that the epidemic peak may reach the early-middle July 2020, initializing recovered R0 TRANS to 0 and Infected I0 to 1. The outcomes of the model will help epidemiologist to isolate the source of the disease MESHD geospatially and analyze the death MESHD. Also government authorities will be able to target their interventions for rapidly checking the spread of the epidemic.

    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.

    BackgroundWith more than 1 million confirmed cases TRANS of coronavirus disease MESHD 2019 (COVID-19) worldwide and more than 50,000 deaths MESHD, the pandemic of Severe Acute Respiratory Syndrome MESHD CoV (SARS-CoV-2) is rapidly evolving. SARS-CoV-2 can also pose a higher risk to pregnant women, due to their immunosuppression during pregnancy. This study investigates the emerging and most UpToDate published scientific literature on the clinical feature and management recommendations for pregnant women with COVID-19.MethodA wide range of published scientific literature was systematically searched from PubMed, Embase, Scopus, Web of Science, and “Global research on coronavirus disease MESHD (COVID-19)” managed by the World Health Organization, published between 1 January 2019 to 27 March 2020. No limitations were used for geographical location, and articles published in English were included in the review. Results for the eligible studies were charted, analyzed, and presented in a narrative format. ResultOur study identified 52 unique articles, and 29 of those articles were included in this review after fulltext screening. Participants were mostly in their third trimester and presented with fever MESHD fever HP, dry cough MESHD cough HP, myalgia MESHD myalgia HP, shortness, and difficulty in breathing. Ground-glass opacity in the computerized tomography scan of the chest was the cardinal feature of COVID-19 pneumonia MESHD pneumonia HP. Except for two participants, severe pneumonia MESHD pneumonia HP did not occur among pregnant women. Pregnant women with COVID-19 were treated with a wide range of antiviral drugs. Higher episodes of preterm birth and cesarean delivery were observed; however, it cannot be explicitly attributed to the SARS-CoV-2. There is no published evidence on the vertical transmission TRANS of SARS-CoV-2. Pregnancy with COVID-19 infection MESHD must be managed by a collaborative team of healthcare professionals during antenatal, delivery, or postnatal stage. Detailed contact tracing TRANS, investigating travel TRANS history, radiological assessment, and laboratory tests with regular fetal health monitoring must be done. ConclusionThe emerging evidence of higher perinatal complications puts pregnant women in a further vulnerable condition. Cautiousness is imperative during the clinical management of pregnant women with COVID-19, as there is no approved treatment regime available at this moment. More research is necessary to fill the gaps in the knowledge of the clinical spectrum of COVID-19 among pregnant women.

    Abstract Objective: The aim of this systematic review was to examine published and preprint reports for maternal and fetal outcomes in pregnant women with COVID-19 and also assess the incidence of maternal-fetal transmission TRANS of SARS CO-V-2 infection MESHD. Design : Systematic review Data sources:We searched PUMBED. Medline, Embase, MedRxiv and bioRxiv databases upto 31st March 2020 utilizing combinations of word variants for " coronavirus " or " COVID-19 " or " severe acute respiratory syndrome MESHD " or " SARS-COV-2 " and " pregnancy " . We also included data from preprint articles. Study selection : Original case reports and case series on pregnant women with a confirmed diagnosis of SARS-CoV-2 infection MESHD. Data extraction : We included 23 studies [China (20), USA (01), Republic of Korea (01) and Honduras, Central America (01) reporting the information on 172 pregnant women and 162 neonates. The primary outcome measures were maternal health characteristics and adverse pregnancy outcomes, neonatal outcomes and SARS-CoV-2 infection MESHD in neonates was extracted. Treatments given to pregnant women with COVID-19 were also recorded. Results: Out of 172 women affected by COVID-19 in pregnancy, 160 women had delivered 162 newborns (2 set of twins, 12 ongoing pregnancies). In pregnant women with COVID-19, the most common symptoms were fever MESHD fever HP (54%), cough MESHD cough HP (35%), myalgia MESHD myalgia HP (17%), dyspnea MESHD dyspnea HP (12%) and diarrhea MESHD diarrhea HP (4%). Pneumonia MESHD Pneumonia HP was diagnosed by CT scan imaging in 100 % of COVID-19 pregnant women. Pregnancy complications MESHD included delivery by cesarean section (89%), preterm labor (21%), fetal distress MESHD fetal distress HP (9%) and premature rupture of membranes HP rupture MESHD of membranes (8%). The most common co-morbidities associated with pregnant women with COVID-19 were diabetes (11%), hypertensive disorders (9%), placental disorders (5%), co- infections MESHD (6%), scarred HP uterus (5%), hypothyroidism MESHD hypothyroidism HP (5%) and anemia MESHD anemia HP (4%). Amongst the neonates of COVID-19 mothers, preterm birth (23%), respiratory distress HP syndrome MESHD (14%), pneumonia MESHD pneumonia HP (14%) low birth weight MESHD (11%), small for gestational age HP age TRANS (3%) were reported. There was one still birth and one neonatal death MESHD reported. Vertical transmission TRANS rate of SARS-CoV-2 is estimated to be 11%. Conclusion In pregnant women with COVID-19, diabetes and hypertensive disorders are common co-morbidities and there is a risk of preterm delivery. Amongst the neonates born to mothers with COVID-19, respiratory distress HP syndrome MESHD and pneumonia MESHD pneumonia HP are common occurrence. There is an evidence of vertical transmission TRANS of SARS-CoV-2 infection MESHD in women with COVID-19.
