BackgroundIn India, the SARS-CoV-2 COVID-19 epidemic has grown to 1251 cases and 32 deaths as on 30 Mar 2020. The healthcare impact of the epidemic in India was studied using a stochastic mathematical model.MethodsA compartmental SEIR model was developed, in which the flow of individuals through compartments is modeled using a set of differential equations. Different scenarios were modeled with 1000 runs of Monte Carlo simulation each using MATLAB. Hospitalization, intensive care unit (ICU) requirements, and deaths were modeled on SimVoi software. The impact of nonpharmacological interventions (NPIs) including social distancing and lockdown on checking the epidemic was estimated.ResultsUninterrupted epidemic in India would have resulted in more than 364 million cases and 1.56 million deaths with peak by mid-July. As per the model, at current growth rate of 1.15, India is likely to reach approximately 3 million cases by 25 May, implying 125,455 (±18,034) hospitalizations, 26,130 (±3298) ICU admissions, and 13,447 (±1819) deaths. This would overwhelm India's healthcare system. The model shows that with immediate institution of NPIs, the epidemic might still be checked by mid-April 2020. It would then result in 241,974 (±33,735) total infections, 10,214 (±1649) hospitalizations, 2121 (±334) ICU admissions, and 1081 (±169) deaths.ConclusionAt the current growth rate of epidemic, India's healthcare resources will be overwhelmed by the end of May. With the immediate institution of NPIs, total cases, hospitalizations, ICU requirements, and deaths can be reduced by almost 90%. 相似文献

BackgroundThere is a deluge of information and misinformation about COVID-19. The present survey was conducted to explore the sources of information /misinformation for healthcare professionals from India.MethodsA cross-sectional online survey using snowballing technique was conducted from 24 Mar to 10 Apr 2020. The questionnaire was pretested and developed using standard techniques. It was circulated among medical students and physicians. Data were analysed using the STATA software.ResultsData of 758 participants were analysed. A total of 255 (33.6%) medical students, 335 (44.2%) nonspecialists and 168 (22.1%) specialists participated. The most common source of formal and informal information was official government websites and online news, respectively. A total of 517 (68.2%) participants accepted receiving misinformation. Social media and family and friends were the most common sources of misinformation. Seventy-two percent of participants agreed that spread of information helped to contain COVID-19, but more than that 75% agreed to having received inaccurate information. Seventy-four percent of respondents felt the need for regulation of information during such times; 26% and 33% felt that information about COVID-19 made them feel uncomfortable and distracts routine decision-making, respectively, and 50% felt it was difficult to differentiate correct from incorrect information about COVID-19.ConclusionThe study explored the sources of information and misinformation and found a high prevalence of misinformation, especially from social media. We suggest the need to better manage the flow of information so that it can be an effective weapon against SARS-CoV2. There is a need for doctors to adapt to the changing times of infodemics accompanying pandemics. 相似文献

BackgroundThe mathematical modelling of coronavirus disease-19 (COVID-19) pandemic has been attempted by a wide range of researchers from the very beginning of cases in India. Initial analysis of available models revealed large variations in scope, assumptions, predictions, course, effect of interventions, effect on health-care services, and so on. Thus, a rapid review was conducted for narrative synthesis and to assess correlation between predicted and actual values of cases in India.MethodsA comprehensive, two-step search strategy was adopted, wherein the databases such as Medline, google scholar, MedRxiv, and BioRxiv were searched. Later, hand searching for the articles and contacting known modelers for unpublished models was resorted. The data from the included studies were extracted by the two investigators independently and checked by third researcher.ResultsBased on the literature search, 30 articles were included in this review. As narrative synthesis, data from the studies were summarized in terms of assumptions, model used, predictions, main recommendations, and findings. The Pearson’s correlation coefficient (r) between predicted and actual values (n = 20) was 0.7 (p = 0.002) with R2 = 0.49. For Susceptible, Infected, Recovered (SIR) and its variant models (n = 16) ‘r’ was 0.65 (p = 0.02). The correlation for long-term predictions could not be assessed due to paucity of information.ConclusionReview has shown the importance of assumptions and strong correlation between short-term projections but uncertainties for long-term predictions. Thus, short-term predictions may be revised as more and more data become available. The assumptions too need to expand and firm up as the pandemic evolves. 相似文献

Since the beginning of Corona Virus Disease (COVID) pandemic, there has been lack of clarity about the management protocols in spite of frequently updated national and international guidelines. Irrational use of unproven therapies has not been helpful in improving treatment outcomes. Early use of high-dose steroids or late use of antiviral medicines might have caused more harm than the benefit. There is also lot of fear about post-COVID fibrosis leading to extended use of steroids and antifibrotics. We reviewed the available COVID guidelines and treatment protocols in the light of scientific evidence generated over last 2 years by a systematic literature search using various databases (PubMed, Google Scholar, MEDLINE, UpToDate, Embase, and Web of Science). This article presents a comprehensive approach to the diagnosis, appropriate investigations, their interpretations, and use of specific therapies according to the stage of disease. 相似文献

Bronchiectasis (BE) has been linked to past viral infections such as influenza, measles, or adenovirus. Two years ago, a new pandemic viral infection severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) broke out and it still persists today, and a significant proportion of surviving patients have radiological and clinical sequelae, including BE. Our aim was to thoroughly review the information available in the literature on the bidirectional relationship between SARS-CoV-2 infection and the development of BE, as well as the impact of this infection on patients already suffering from BE. Available information indicates that only a small percentage of patients in the acute phase of coronavirus disease 2019 (COVID-19) pneumonia develop BE, although the latter is recognized as one of the radiological sequelae of COVID-19 pneumonia, especially when it is caused by traction. The severity of the initial pneumonia is the main risk factor for the development of future BE, but during the COVID-19 pandemic, exacerbations in BE patients were reduced by approximately 50%. Finally, the impact of BE on the prognosis of patients with COVID-19 pneumonia is not yet known. 相似文献

A large-scale vaccination of coronavirus disease-19 (COVID-19) in adults has been conducted for nearly a year, and there is a growing recognition that immunization for children is also essential. It has been months since emergency use of pediatric COVID-19 vaccine was approved, we reviewed the prevalence and transmission of COVID-19 in children. The prevalence of COVID-19 in children is reduced due to vaccination even in a Delta prevalent period, so an increase in the vaccination rate is needed in children. Although the precise role of children in the transmission requires more research to uncover, they likely played a significant role, according to the available literature. We also described four candidate COVID-19 vaccines for children on their safety and immunogenicity and the impact of severe acute respiratory syndrome coronavirus 2 variants on childhood vaccination. Safety issues on pediatric vaccines post-approval, like adverse events following immunization and adverse events of special interest require studies on long-term and effective regulatory mechanisms. 相似文献

Since December 2019, severe acute respiratory syndrome coronavirus 2 has been found to be the culprit in the coronavirus disease 2019 (COVID-19), causing a global pandemic. Despite the existence of many vaccine programs, the number of confirmed cases and fatalities due to COVID-19 is still increasing. Furthermore, a number of variants have been reported. Because of the absence of approved anti-coronavirus drugs, the treatment and management of COVID-19 has become a global challenge. Under these circumstances, drug repurposing is an effective method to identify candidate drugs with a shorter cycle of clinical trials. Here, we summarize the current status of the application of drug repurposing in COVID-19, including drug repurposing based on virtual computer screening, network pharmacology, and bioactivity, which may be a beneficial COVID-19 treatment. 相似文献

Objectives:To explore the impact of the COVID-19 pandemic on the development of obsessive-compulsive disorder (OCD) symptoms and its correlation with the level of perceived stress among the Saudi population.Methods:In July 2020, a cross-sectional survey of 2909 participants in Saudi Arabia during the outbreak was conducted to collect data related to sociodemographic characteristics and scores on the Brief Obsessive-Compulsive Scale (BOCS) and Perceived Stress Scale (PSS).Results:Most participants were female (73.9%) with a university level of education or higher (81%). The prevalence of new-onset obsessions was 57.8%, compulsions 45.9%, and moderate/high perceived stress 72.4%. New-onset dirt, germs, and virus obsessions were significantly higher among 40-49 age group, employees, housewives, students, quarantine discipliners, and those who spent 20 or more days in quarantine. New-onset hand-washing compulsions were significantly higher among the 30-49 age group. A significantly higher level of perceived stress was reported among those in the 18-29 age group, females, singles, participants with no children, students, non-smokers, those who were unemployed, living with families, diagnosed with a psychiatric disorder, living in the northern region, quarantine discipliners, and those who spent 60 or more days in quarantine.Conclusion:This study revealed a significantly higher prevalence of high perceived stress in respondents with new-onset OCD contamination symptoms during the COVID-19 pandemic. This implies that a biodisaster is associated with high psychological morbidity. 相似文献
