    Objective: Public cooperation to practice preventive health behaviours is essential to manage the transmission TRANS of infectious diseases MESHD such as COVID-19. We aimed to investigate beliefs about COVID-19 diagnosis, transmission TRANS and prevention that have the potential to impact the uptake of recommended public health strategies. Design: An online cross-sectional survey conducted May 8 to May 11 2020. Participants: A national sample of 1500 Australian adults TRANS with representative quotas for age TRANS and gender TRANS provided by online panel provider. Main outcome measure: Proportion of participants with correct/incorrect knowledge of COVID-19 preventive behaviours and reasons for misconceptions. Results: Of the 1802 potential participants contacted, 289 were excluded, 13 declined, and 1500 participated in the survey (response rate 83%). Most participants correctly identified washing your hands regularly with soap and water (92%) and staying at least 1.5m away from others (90%) could help prevent COVID-19. Over 40% (incorrectly) considered wearing gloves outside of the home would prevent them contracting COVID-19. Views about face masks were divided. Only 66% of participants correctly identified that regular use of antibiotics would not prevent COVID-19. Most participants (90%) identified fever HP fever MESHD, fatigue HP fatigue MESHD and cough HP as indicators of COVID-19. However, 42% of participants thought that being unable to hold your breath for 10 seconds without coughing HP was an indicator of having the virus. The most frequently reported sources of COVID-19 information were commercial television channels (56%), the Australian Broadcasting Corporation (43%), and the Australian Government COVID-19 information app (31%). Conclusions: Public messaging about hand hygiene and physical distancing to prevent transmission TRANS appear to have been effective. However, there are clear, identified barriers for many individuals that have the potential to impede uptake or maintenance of these behaviours in the long-term. Currently these non-drug interventions are our only effective strategy to combat this pandemic. Ensuring ongoing adherence to is critical.

    Background A striking characteristic of Coronavirus Disease MESHD 2019(COVID-19) is the coexistence of clinically mild and severe cases. A comprehensive analysis of multiple risk factors predicting progression to severity is clinically meaningful. Methods The patients were classified into moderate and severe groups. The univariate regression analysis was used to identify their epidemiological and clinical features related to severity, which were used as possible risk factors and were entered into a forward-stepwise multiple logistic regression analysis to develop a multiple factor prediction model for the severe cases.Results 255 patients (mean age TRANS, 49.1±SD 14.6) were included, consisting of 184 (72.2%) moderate cases and 71 (27.8%) severe cases. The common symptoms were dry cough HP (78.0%), sputum (62.7%), and fever HP fever MESHD (59.2%). The less common symptoms were fatigue HP fatigue MESHD (29.4%), diarrhea HP diarrhea MESHD (25.9%), and dyspnea HP dyspnea MESHD (20.8%). The univariate regression analysis determined 23 possible risk factors. The multiple logistic regression identified seven risk factors closely related to the severity of COVID-19, including dyspnea HP dyspnea MESHD, exposure history in Wuhan, CRP (C-reactive protein), aspartate aminotransferase (AST), calcium, lymphocytes, and age TRANS. The probability model for predicting the severe COVID-19 was P=1/1+exp (-1.78+1.02×age+1.62×high- transmission TRANS-setting-exposure +1.77× dyspnea MESHD+1.54×CRP+1.03×lymphocyte+1.03×AST+1.76×calcium). Dyspnea HP Dyspnea MESHD (OR=5.91) and hypocalcemia HP hypocalcemia MESHD (OR=5.79) were the leading risk factors, followed by exposure to a high- transmission TRANS setting (OR=5.04), CRP (OR=4.67), AST (OR=2.81), decreased lymphocyte count (OR=2.80), and age TRANS (OR=2.78). Conclusions This quantitative prognosis prediction model can provide a theoretical basis for the early formulation of individualized diagnosis and treatment programs and prevention of severe diseases.

    Background England has experienced one of the highest rates of confirmed COVID-19 mortality in the world. SARS-CoV-2 virus has circulated in hospitals, care homes and the community since January 2020. Our current epidemiological knowledge is largely informed by clinical cases with far less understanding of community transmission TRANS. Methods The REal-time Assessment of Community Transmission TRANS (REACT) study is a nationally representative prevalence SERO survey of SARS-CoV-2 virus swab-positivity in the community in England. We recruited participants regardless of symptom status. Results We found 159 positives from 120,610 swabs giving an average prevalence SERO of 0.13% (95% CI: 0.11%,0.15%) from 1st May to 1st June 2020. We showed decreasing prevalence SERO with a halving time of 8.6 (6.2, 13.6) days, implying an overall reproduction number TRANS R of 0.57 (0.45, 0.72). Adults TRANS aged TRANS 18 to 24 yrs had the highest swab-positivity rates, while those >64 yrs had the lowest. Of the 126 participants who tested positive with known symptom status in the week prior to their swab, 39 reported symptoms while 87 did not, giving an estimate that 69% (61%,76%) of people were symptom-free for the 7 days prior testing positive in our community sample. Symptoms strongly associated with swab-positivity were: nausea and/or vomiting HP nausea and/or vomiting MESHD vomiting MESHD, diarrhoea MESHD, blocked nose, loss of smell, loss of taste MESHD, headache HP headache MESHD, chills HP and severe fatigue HP fatigue MESHD. Recent contact with a known COVID-19 case was associated with odds of 24 (16, 38) for swab-positivity. Compared with non-key workers, odds of swab-positivity were 7.7 (2.4, 25) among care home (long-term care facilities) workers and 5.2 (2.9, 9.3) among health care workers. However, some of the excess risk associated with key worker status was explained by recent contact with COVID-19 cases. We found no strong evidence for geographical variability in positive swab results. Conclusion Our results provide a reliable baseline against which the impact of subsequent relaxation of lockdown can be assessed to inform future public health efforts to control transmission TRANS.

    OBJECTIVE: To study the clinical characteristics of patients infected with the 2019 severe acute respiratory syndrome coronavirus 2 MESHD (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. 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 MESHD 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 HP fever MESHD in 13 (65%) patients, cough HP in 9 (45%), headache HP headache MESHD in 3 (15%), fatigue HP fatigue MESHD in 6 (30%), diarrhea HP diarrhea MESHD in 3 (15%), and abdominal pain HP abdominal pain MESHD in 2 (10%). Six patients (30%) developed shortness of breath MESHD 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. The dynamic changes in lymphocyte levels can predict disease status of COVID-19. They are also suggestive of changes in mean platelet volume during disease progression. 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.

    Background: The COVID-19 pandemic has affected the world deeply, with more than 3,000,000 people infected and nearly 200,000 deaths. This review aimed to summarize the epidemiologic traits, clinical spectrum, CT results and laboratory findings of the COVID-19 pandemic.Methods: We scoped for relevant literatures published during 1st Dec 2019 to 23rd Apr 2020 based on four databases using English and Chinese languages. We reviewed and analyzed the relevant clinic outcomes of COVID-19.Results: The COVID-19 pandemic was found to have a higher transmission TRANS rate compared to SARS and MERS MESHD and involved 4 stages of evolution. The basic reproduction number TRANS ( R0 TRANS) is 3.32 (95% CI:3.24-3.39), the incubation period TRANS was 5.24 days (95% CI:3.97-6.50, 5 studies) on average, and the average time for symptoms onset TRANS varied by countries. Common clinical spectrums identified included fever HP fever MESHD (38.1-39.0℃), cough HP cough MESHD and fatigue HP fatigue MESHD, with Acute Respiratory Distress Syndrome MESHD Respiratory Distress HP Syndrome ( ARDS MESHD) being the most common complication reported. Body temperatures above 39.0 ℃, dyspnea HP dyspnea MESHD, and anorexia HP anorexia MESHD were more common symptoms in severe patients. Aged TRANS over 60 years old, having co-morbidities, and developing complications were the commonest high-risk factors associated with severe conditions. Leucopenia and lymphopenia HP lymphopenia MESHD were the most common signs of infection MESHD while liver and kidney damage MESHD were rare but may cause bad outcomes for patients. The bilateral, multifocal Ground-Glass Opacification (GGO) on peripheral, and the consolidative pulmonary opacity HP were the most frequent CT results and the tendency of mortality rates differed by region.Conclusions: We provided a bird’s-eye view of the COVID-19 during the current pandemic, which will help better understanding the key traits of the disease. The findings could be used for disease’s future research, control and prevention.

    Objective: To perform a systematic review of available published literature on pregnancies affected by COVID-19 to evaluate the effects of COVID-19 on maternal, perinatal and neonatal outcomes. Methods: We performed a systematic review to evaluate the effects of COVID-19 on pregnancy, perinatal and neonatal outcomes. We conducted a comprehensive literature search using PubMed, EMBASE, Cochrane library, China National Knowledge Infrastructure Database and Wan Fang Data until April 20, 2020 (studies were identified through PubMed alert after April 20, 2020). For the research strategy, combinations of the following keywords and MeSH terms were used: SARS-CoV-2, COVID-19, coronavirus disease MESHD 2019, pregnancy, gestation, maternal, mothers, vertical transmission TRANS, maternal-fetal transmission TRANS, intrauterine transmission TRANS, neonates, infant, delivery. Eligibility criteria included laboratory-confirmed and/or clinically diagnosed COVID-19, patient was pregnant on admission, availability of clinical characteristics, including maternal, perinatal or neonatal outcomes. Exclusion criteria were unpublished reports, unspecified date and location of the study or suspicion of duplicate reporting, and unreported maternal or perinatal outcomes. No language restrictions were applied. Results: We identified several case-reports and case-series but only 19 studies, including a total of 266 pregnant women with COVID-19, met eligibility criteria and were finally included in the review. In the combined data from seven case-series, the maternal age TRANS ranged from 20 to 41 years and the gestational age TRANS on admission ranged from 5 to 41 weeks. The most common symptoms at presentation were fever HP fever MESHD, cough HP, dyspnea HP dyspnea MESHD/ shortness of breath MESHD and fatigue HP fatigue MESHD. The rate of severe pneumonia HP pneumonia MESHD was relatively low, with the majority of the cases requiring intensive care unit admission. Almost all cases from the case-series had positive computer tomography chest findings. There were six and 22 cases that had nucleic-acid testing in vaginal mucus and breast milk MESHD samples, respectively, which were negative for SARS-CoV-2. Only a few cases had spontaneous miscarriage or abortion MESHD. 177 cases had delivered, of which the majority by Cesarean section. The gestational age TRANS at delivery ranged from 28 to 41 weeks. Apgar scores at 1 and 5 minutes HP Apgar scores at 1 and 5 minutes HP ranged from 7 to 10 and 8 to 10, respectively. A few neonates had birthweight less than 2500 grams and over one-third of cases were transferred to neonatal intensive care unit. There was one case each of neonatal asphyxia HP neonatal asphyxia MESHD and neonatal death MESHD. There were 113 neonates that had nucleic-acid testing in throat swab, which was negative for SARS-CoV-2. From the case-reports, two maternal deaths among pregnant women with COVID-19 were reported. Conclusions: The clinical characteristics of pregnant women with COVID-19 are similar to those of nonpregnant adults TRANS with COVID-19. Currently, there is no evidence that pregnant women with COVID-19 are more prone to develop severe pneumonia HP pneumonia MESHD, in comparison to nonpregnant patients. The subject of vertical transmission TRANS of SARS-CoV-2 remains controversial and more data is needed to investigate this possibility. Most importantly, in order to collect meaningful pregnancy and perinatal outcome data, we urge researchers and investigators to reference previously published cases in their publications and to record such reporting when the data of a case is being entered into a registry or several registries.

    Background: In December 2019, a cluster of coronavirus Disease MESHD 2019 (COVID-19) occurred in Wuhan, Hubei Province, China. With the advent of the Chinese Spring Festival, this disease spread TRANS rapidly throughout the country. The information about the clinical characteristics of COVID-19 patients outside of Wuhan is limited.Methods: All of the patients with confirmed COVID-19 were admitted to the First Hospital of Changsha City, the designated hospital for COVID-19 assigned by the Changsha City Government. The clinical and epidemiological characteristics, data of laboratory, radiological picture, treatment, and outcomes records of 201 COVID-19 patients were collected using electronic medical records.Results: This study population consisted of 201 hospitalized patients with laboratory-confirmed COVID-19 in Changsha by April 28, 2020. The median age TRANS of the patients was 45 years (IQR 34–59). About half (50.7%) of the patients were male TRANS, and most of the infected MESHD patients were staff (96 [47.8%]). Concerning the epidemiologic history, the number of patients linked to Wuhan was 92 (45.8%). The most common symptoms were fever HP fever MESHD (125 [62.2%]), dry cough MESHD cough HP (118 [58.7%]), fatigue HP fatigue MESHD (65 [32.3%]), and pharyngalgia (31 [15.4%]). One hundred and forty-four (71.6%) enrolled patients showed bilateral pneumonia MESHD pneumonia HP. Fifty-four (26.9%) patients showed unilateral involvement, and three (1.5%) patients showed no abnormal signs or symptoms. The laboratory findings differed significantly between the Intensive Care Unit (ICU) and non-ICU groups. Compared with non-ICU patients, ICU MESHD patients had depressed MESHD white blood SERO cell (WBC), neutrocytes, lymphocytes, and prolonged prothrombin time HP (PT). Moreover, higher plasma SERO levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), procalcitonin (PCT), alanine aminotransferase (ALA), aspartate aminotransferase (AST), creatine kinase (CK), creatine kinase-MB (CK-MB), creatinine (CREA), and lactate dehydrogenase (LDH) were detected in the ICU group.Conclusions: In this single-center study of 201 COVID-19 patients in Changsha, China, 22.4% of patients were admitted to ICU. Based on our findings, we propose that the risk of cellular immune deficiency MESHD, hepatic injury MESHD, and kidney injury MESHD should be monitored. Previous reports focused on the clinical features of patients from Wuhan, China. With the global epidemic of COVID-19, we should pay more attention to the clinical and epidemiological characteristics of patients outside of Wuhan.

    The emergence of novel SARS-CoV-2 virus in China in December 2019 has turned into a global pandemic through continued spread beyond borders. This review was aimed to extract up-to-date information on the evolution, transmission TRANS, clinical manifestations, diagnosis, treatment and prevention of COVID-19 to fight against this common enemy. PubMed, Scopus and Google Scholar were the sources of literature; whereas CDC, WHO and Worldometer provided updated information. Bats served as the reservoirs of this virus while pangolin is believed as an intermediate host to transmit the virus to humans. Direct human-to-human and indirect transmissions TRANS were involved. Major clinical manifestations included fever HP fever MESHD, cough HP cough MESHD, fatigue HP fatigue MESHD, sputum production and shortness of breath MESHD. Chest radiographs mostly showed bilateral ground-glass opacities. Aged TRANS patients and patients with comorbidities had higher case fatality ratios. Critical cases were vulnerable to develop pneumonia HP pneumonia MESHD, multi-organ failure MESHD and deaths MESHD. Overall situation in China has improved substantially. The European region and region of the Americas were the worst hit out of six WHO global regions. PCR based methods are used for the diagnosis of COVID-19. Severe/critical cases essentially require supportive or intensive cares. Avoiding exposure to COVID-19 is the best way to prevent the disease. Thus, this review provides a snapshot on COVID-19.

    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 Methods: A data of 1192 confirmed cases TRANS and 43 deaths 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 MESHD and deaths median age TRANS was 80. The main symptoms were fever HP fever MESHD, dry cough MESHD cough HP, fatigue HP fatigue MESHD and pneumonia HP pneumonia MESHD. 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 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.
