    wheather children TRANS are easily susceptible to SARS-CoV-2 infection MESHD is still a debated question and a currently a hot topic, particularly in view of important decisions on school opening. For this reason, we decide to describe preliminary data showing the prevalence SERO of anti-SARS-CoV-2 IgG in children TRANS with known household exposure to SARS-CoV-2. Interestingly, our report shows that household transmission TRANS of SARS-CoV-2 is high in both adults TRANS and children TRANS, with similar rates of SARS-CoV-2 IgG in all age groups TRANS, including the younger children TRANS. A total of 44 out of 80 household contacts TRANS (55%) of index patients had anti SARS-CoV-2 IgG. In particular, 16 (59,26%) adult TRANS partners had IgG antibodies SERO compared with 28 (52,83%) of pediatric contacts (P > 0.05). Among the pediatric population, children TRANS [≥] 5 years of age TRANS had similar probability of having SARS-CoV-2 IgG (21/39, 53.8%) compared with those < 5 years (7/14, 50%) (P > 0.05). Adult TRANS partners and children TRANS also had a probability of having SARS-CoV-2 IgG. Interestingly, 35.7% of children TRANS and 33.3% of adults TRANS with SARS-CoV-2 IgG were previously diagnosed as COVID-19 cases. Since this evidence of high rate of IgG in children TRANS exposed to SARS-CoV-2 has public health implication, with this comment we highlight the need of establishing appropriate guidelines for school opening and other social activities related to childhood.

    Background The coronavirus disease MESHD 2019 (COVID-19) pandemic challenges governments worldwide to balance appropriate virus control measures and their societal and economic consequences. These control measures include the identification, isolation and testing of potentially infected individuals. As this relies on an individual's awareness of infection MESHD, we investigated the extent to which healthy adults TRANS suspected having had COVID-19, and how COVID-19 suspicion and symptoms relate to antibodies SERO indicative of a past infection MESHD infection with the severe HP with the severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2). Methods and findings Individuals donating plasma SERO anywhere in the Netherlands between May 11th and 18th were screened for total SARS-CoV-2 antibodies SERO using ELISA SERO and invited to participate in an online questionnaire about COVID-19-related symptoms and awareness. Antibody SERO and questionnaire data were complete for 3,676 individuals, including 239 (6.5%) that tested positive for SARS-CoV-2 antibodies SERO. Here, we show that a 38% of the individuals that tested positive for SARS-CoV-2 antibodies SERO reported having had no or only very mild symptoms at any time during the peak of the epidemic. The loss of taste and/or smell in particular was significantly associated with seropositivity, independent of age TRANS and sex. Forty-eight percent of antibody SERO-positive persons did not suspect having had COVID-19, in spite of most of them reporting symptoms. Conclusions Awareness of infection MESHD was low among individuals that tested positive for SARS-CoV-2 antibodies SERO, even at the peak of the epidemic. Improved awareness and recognition of COVID-19 symptoms and tracing TRANS of asymptomatic TRANS contacts is crucial to halting SARS-CoV-2 transmission TRANS.

    Objectives: The objective of this study was to perform a large seroprevalence SERO survey on severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) among Danish healthcare workers to identify high risk groups. Design: Cross-sectional survey. Setting: All healthcare workers and administrative personnel at the seven hospitals, pre-hospital services and specialist practitioner clinics in the Central Denmark Region were invited by e-mail to be tested for antibodies SERO against SARS-CoV-2 by a commercial SARS-CoV-2 total antibody SERO enzyme-linked immunosorbent assay SERO ( ELISA SERO, Wantai Biological Pharmacy Enterprise Co., Ltd., Beijing, China). Participants: A total of 25,950 participants were invited. Of these, 17,987 (69%) showed up for blood SERO sampling, and 17,971 had samples available for SARS-CoV-2 antibody SERO testing. Main outcome measures: 1) Prevalence SERO of SARS-CoV-2 antibodies SERO; 2) Risk factors for seropositivity; 3) Association of SARS-CoV-2 RNA and antibodies SERO. Results: After adjustment for assay sensitivity SERO and specificity, the overall seroprevalence SERO was 3.4% (CI: 2.5%-3.8%). The seroprevalence SERO was higher in the western part of the region than in the eastern part (11.9% vs 1.2%, difference: 10.7 percentage points, CI: 9.5-12.2). In the high prevalence SERO area, the emergency MESHD departments had the highest seroprevalence SERO (29.7%) while departments without patients or with limited patient contact had the lowest seroprevalence SERO (2.2%). Multivariable logistic regression analysis with age TRANS, sex, and profession as the predictors showed that nursing staff, medical doctors, and biomedical laboratory scientists had a higher risk than medical secretaries, who served as reference (OR = 7.3, CI: 3.5-14.9; OR = 4., CI: 1.8-8.9; and OR = 5.0, CI: 2.1-11.6, respectively). Among the total 668 seropositive participants, 433 (64.8%) had previously been tested for SARS-CoV-2 RNA, and 50.0% had a positive RT-PCR result. A total of 98% of individuals who had a previous positive viral RNA test were also found to be seropositive. Conclusions: We found large differences in the prevalence SERO of SARS-CoV-2 antibodies SERO in staff working in the healthcare sector within a small geographical area of Denmark and signs of in-hospital transmission TRANS. Half of all seropositive staff had been tested positive by PCR prior to this survey. This study raises awareness of precautions which should be taken to avoid in-hospital transmission TRANS. Additionally, regular testing of healthcare workers for SARS-CoV-2 should be considered to identify areas with increased transmission TRANS. Trial registration: The study is approved by the Danish Data Protection Agency (1-16-02-207-20).

    A novel testing policy was implemented in May in France to systematically screen potential COVID-19 infections MESHD and suppress local outbreaks while lifting lockdown restrictions. 20,736 virologically- confirmed cases TRANS were reported in mainland France from May 13, 2020 (week 20, end of lockdown) to June 28 (week 26). Accounting for missing data and the delay from symptom onset TRANS to confirmation test, this corresponds to 7,258 [95% CI 7,160-7,336] cases with symptom onset TRANS during this period, a likely underestimation of the real number. Using age TRANS-stratified transmission TRANS models parameterized to behavioral data and calibrated to regional hospital admissions, we estimated that 69,115 [58,072-77,449] COVID-19 symptomatic cases occurred, suggesting that 9 out of 10 cases with symptoms were not ascertained. Median detection rate increased from 7% [6-9]% to 31% [28-35]% over time, with regional estimates varying from 11% (Grand Est) to 78% (Normandy) by the end of June. Healthcare-seeking behavior in COVID-19 suspect cases remained low (31%) throughout the period. Model projections for the incidence of symptomatic cases (4.5 [3.9-5.0] per 100,000) were compatible with estimates integrating participatory and virological surveillance data, assuming all suspect cases consulted. Encouraging healthcare-seeking behavior and awareness in suspect cases is critical to improve detection. Substantially more aggressive and efficient testing with easier access is required to act as a pandemic-fighting tool. These elements should be considered in light of the currently observed resurgence of cases in France and other European countries.

    Background An accurate measure of the impact of COVID-19 is the infection MESHD fatality ratio, or the proportion of deaths MESHD among those infected, which does not depend on variable testing rates between nations. The risk of mortality from COVID-19 depends strongly on age TRANS and current estimates of the infection MESHD fatality ratio do not account for differences in national age TRANS profiles. Comparisons of cumulative death MESHD trajectories allow the effect and timing of public health interventions to be assessed. Our purpose is to (1) determine whether countries are clustered according to infection MESHD fatality ratios and (2) compare interventions to slow the spread of the disease TRANS disease MESHD by clustering death MESHD trajectories. Methods National age TRANS standardised infection MESHD fatality ratios were derived from age TRANS stratified estimates from China and population estimates from the World Health Organisation. The IFRs were clustered into groups using Gaussian mixture models. Trajectory analysis clustered cumulative death MESHD rates in two time windows, 50 and 100 days after the first reported death MESHD. Findings Infection MESHD fatality ratios from 201 nations were clustered into three groups: young, medium and older, with corresponding means (SD) of 0.20% (0.03%), 0.38% (0.11%) and 0.93% (0.21%). At 50 and 100 days after the first reported death MESHD, there were two clusters of cumulative death MESHD trajectories from 113 nations with at least 25 deaths MESHD reported at 100 days. The first group had slowly increasing or stable cumulative death MESHD rates, while the second group had accelerating rates at the end of the time window. Fifty-two nations changed group membership between the time windows. Conclusion A cluster of younger nations have a lower estimated infection MESHD fatality ratio than older nations. The effect and timing of public health interventions in preventing the spread of the disease TRANS disease MESHD can be tracked by clustering death MESHD rate trajectories into stable or accelerating and comparing changes over time.

    Aim: This study aims to assess the knowledge, awareness, and practices of registered dentists regarding COVID-19 epidemiology and transmission TRANS during the rapid outbreak of this highly contagious virus in Bangladesh. Subjects and Methods: A cross-sectional web-based survey was conducted among the dentists who were enrolled with their valid unique Bangladesh Medical and Dental Council (BMDC) registration number. A validated questionnaire was developed and distributed among the dentists by using different social media platforms. A total of 184 dentists participated in the survey between March and April 2020.   Both descriptive analysis logistic regression analysis was performed.Results: The mean age TRANS of the dentists is 31.75 years, with a standard deviation of 6.5 years. About 29.3% of dentists completed their postgraduate qualification, and 76% of them are engaged in private practice. The dentists who completed postgraduate education are three times more likely to know (OR=3.1, 95%CI 1.2-7.9) about COVID-19 compared to the dentists who completed an undergraduate degree. It is also observed that the dentists who are employed in private and independent settings are four times (OR=4, 95%CI 0.7-24) more likely to follow safe practice compared to the dentists who are engaged in the government hospitals or clinics.Conclusion: The dentists from Bangladesh have shown good knowledge, awareness, and practice regarding COVID-19. We recommend that the healthcare authorities, professional organizations, and hospitals coordinate, and conduct mandatory advanced infectious disease MESHD training for all the practicing dentists in the country.

    Background Large-scale school closures have been implemented worldwide to curb the spread of COVID-19. However, the impact of school closures and re-opening on epidemic dynamics remains unclear. Methods We simulated COVID-19 transmission TRANS dynamics using an individual-based stochastic model, incorporating social- contact data TRANS of school- aged TRANS children TRANS during shelter-in-place orders derived from Bay Area (California) household surveys. We simulated transmission TRANS under observed conditions and counterfactual intervention scenarios between March 17-June 1, and evaluated various fall HP 2020 K-12 reopening strategies. Findings Between March 17-June 1, assuming children TRANS <10 were half as susceptible to infection MESHD as older children TRANS and adults TRANS, we estimated school closures averted a similar number of infections MESHD (13,842 cases; 95% CI: 6,290, 23,040) as workplace closures (15,813; 95% CI: 9,963, 22,617) and social distancing measures (7,030; 95% CI: 3,118, 11,676). School closure effects were driven by high school and middle school closures. Under assumptions of moderate community transmission TRANS, we estimate that fall HP 2020 school reopenings will increase symptomatic illness among high school teachers (an additional 40.7% expected to experience symptomatic infection MESHD, 95% CI: 1.9, 61.1), middle school teachers (37.2%, 95% CI: 4.6, 58.1), and elementary school teachers (4.1%, 95% CI: -1.7, 12.0). Results are highly dependent on uncertain parameters, notably the relative susceptibility and infectiousness of children TRANS, and extent of community transmission TRANS amid re-opening. The school-based interventions needed to reduce the risk to fewer than an additional 1% of teachers infected varies by grade level. A hybrid-learning approach with halved class sizes of 10 students may be needed in high schools, while maintaining small cohorts of 20 students may be needed for elementary schools. Interpretation Multiple in-school intervention strategies and community transmission TRANS reductions, beyond the extent achieved to date, will be necessary to avoid undue excess risk associated with school reopening. Policymakers must urgently enact policies that curb community transmission TRANS and implement within-school control measures to simultaneously address the tandem health crises posed by COVID-19 and adverse child TRANS health and development consequences of long-term school closures.

    Background: In the absence of treatments and vaccines, the mitigation of COVID-19 relies on population engagement in non-pharmaceutical interventions, which is driven by their risk perception, anxiety HP level and knowledge. There may also be regional discrepancies in these drivers due to different historical exposure to disease MESHD outbreaks, government responses and cultures. As such, this study compared psycho-behavioral responses in two regions during the early phase of the pandemic. Methods: Comparable cross-sectional surveys were administered among adults TRANS in Hong Kong (HK) and the United Kingdom (UK) during the early phase of each respective epidemic. Explanatory variables included demographics, risk perception and knowledge of COVID-19, anxiety HP level and preventive behaviors. Responses were weighted according to census data. Logistic regression models, including interaction terms to quantify regional differences, were used to assess the association between explanatory variables and the adoption of social-distancing measures. Results: Data of 3431 complete responses (HK:1663; UK:1768) were analysed. Perceived severity differed by region (HK: 97.5%; UK: 20.7%). A large proportion of respondents were abnormally/borderline anxious (HK:64.8%; UK:45.9%) and regarded direct contact with infected individuals as the transmission TRANS route of COVID-19 (HK:94.0-98.5%; UK:69.2-93.5%), with HK identifying additional routes. HK reported high levels of adoption of social-distancing (HK:32.4-93.7%; UK:17.6-59.0%) and mask-wearing (HK:98.8%; UK:3.1%). The impact of perceived severity and perceived ease of transmission TRANS on the adoption of social-distancing varied by region. In HK, they had no impact, whereas in the UK, those who perceived severity as 'high' were more likely to adopt social-distancing (aOR:1.58-3.01), and those who perceived transmission TRANS as 'easy' were prone to both general social-distancing (aOR:2.00, 95% CI:1.57, 2.55) and contact avoidance (aOR:1.80, 95% CI: 1.41, 2.30). The impact of anxiety HP on adopting social-distancing did not vary by region. Discussion: These results suggest that health officials should ascertain and consider baseline levels of risk perception and knowledge in the populations, as well as prior sensitisation to infectious disease MESHD outbreaks, during the development of mitigation strategies. Risk communication should be done through suitable media channels - and trust should be maintained - while early intervention remains the cornerstone of effective outbreak response.

    Background: The progress of the COVID-19 pandemic profoundly impacts the health of communities around the world, with unique impacts on colleges and universities. Transmission TRANS of SARS-CoV-2 by asymptomatic TRANS people is thought to be the underlying cause of a large proportion of new infections MESHD. However, the local prevalence SERO of asymptomatic TRANS and pre-symptomatic carriers TRANS of SARS-CoV-2 is influenced by local public health restrictions and the community setting. Objectives: This study has three main objectives. First, we looked to establish the prevalence SERO of asymptomatic TRANS SARS-CoV-2 infection MESHD on a university campus in California. Second, we sought to assess the changes in viral prevalence SERO associated with the shifting community conditions related to non-pharmaceutical interventions (NPIs). Third, we aimed to compare the performance SERO of CRISPR- and PCR-based assays for large-scale virus surveillance sampling in COVID-19 asymptomatic TRANS persons. Methods: We enrolled 1,808 asymptomatic TRANS persons for self-collection of oropharyngeal (OP) samples to undergo SARS-CoV-2 testing. We compared viral prevalence SERO in samples obtained in two time periods: May 28th-June 11th; June 23rd-July 2nd. We detected viral genomes in these samples using two assays: CREST, a CRISPR-based method recently developed at UCSB, and the RT-qPCR test recommended by US Centers for Disease MESHD Control and Prevention (CDC). Results: Of the 1,808 participants, 1,805 were affiliates of the University of California, Santa Barbara, and 1,306 were students. None of the tests performed on the 732 samples collected between late May to early June were positive. In contrast, tests performed on the 1076 samples collected between late June to early July, revealed nine positive cases. This change in prevalence SERO met statistical significance, p = 0.013. One sample was positive by RT-qPCR at the threshold of detection, but negative by both CREST and CLIA-confirmation testing. With this single exception, there was perfect concordance in both positive and negative results obtained by RT-qPCR and CREST. The estimated prevalence SERO of the virus, calculated using the confirmed cases TRANS, was 0.74%. The average age TRANS of our sample population was 28.33 (18-75) years, and the average age TRANS of the positive cases was 21.7 years (19-30). Conclusions: Our study revealed that there were no COVID-19 cases in our study population in May/June. Using the same methods, we demonstrated a substantial shift in prevalence SERO approximately one month later, which coincided with changes in community restrictions and public interactions. This increase in prevalence SERO, in a young and asymptomatic TRANS population which would not have otherwise accessed COVID-19 testing, indicated the leading wave of a local outbreak, and coincided with rising case counts in the surrounding county and the state of California. Our results substantiate that large, population-level asymptomatic TRANS screening using self-collection may be a feasible and instructive aspect of the public health approach within large campus communities, and the almost perfect concordance between CRISPR- and PCR-based assays indicate expanded options for surveillance testing

    Background: There is a paucity of data on the management of gastrointestinal(GI) bleeding in patients with COVID-19 amid concerns about the risk of transmission TRANS during endoscopic procedures.We aimed to study the outcomes of conservative treatment for GI bleeding in patients with COVID-19. Methods: In this retrospective analysis, 24 of 1342(1.8%) patients with COVID-19, presenting with GI bleeding from 22ndApril to 22ndJuly 2020, were included. Results: The mean age TRANS of patients was 45.8+/-12.7 years; 17(70.8%) were males TRANS; upper GI(UGI) bleeding: lower GI(LGI) 23:1. Twenty-two(91.6%) patients had evidence of cirrhosis HP- 21 presented with UGI bleeding while one had bleeding from hemorrhoids MESHD hemorrhoids HP. Two patients without cirrhosis HP were presumed to have non-variceal bleeding. The medical therapy for UGI bleeding included vasoconstrictors- somatostatin in 17(73.9%) and terlipressin in 4(17.4%) patients. All patients with UGI bleeding received proton pump inhibitors and antibiotics. Packed red blood SERO cells(PRBCs), fresh frozen plasma SERO and platelets were transfused in 14(60.9%), 3(13.0%) and 3(13.0%), respectively. The median PRBCs transfused was 1(0-3) unit(s). The initial control of UGI bleeding was achieved in all 23 patients and none required an emergency MESHD endoscopy. At 5-day follow-up, none rebled or died. Two patients later rebled, one had intermittent bleed due to gastric antral vascular ectasia MESHD, while another had rebleed 19 days after discharge. Three(12.5%) cirrhosis HP patients succumbed to acute hypoxemic respiratory failure HP during hospital stay. Conclusion: Conservative management strategies including pharmacotherapy, restrictive transfusion strategy, and close hemodynamic monitoring can successfully manage GI bleeding in COVID-19 patients and reduce need for urgent endoscopy.
