The most effective interventions By 23 January 2020, China had imposed a national emergency response to restrict travel and impose social distancing measures on its populace in an attempt inhibit the transmission of severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2). However, which were is uncertain. Tian et al. performed quantitative analysis impact control between 31 December 2019 19 February encompasses Lunar New Year period when millions people traveled across for family...
An outbreak caused by a novel human coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first detected in Wuhan December 2019,1Lu R Zhao X Li J et al.Genomic characterisation and epidemiology of 2019 coronavirus: implications for virus origins receptor binding.Lancet. 2020; (published online Jan 30.)https://doi.org/10.1016/S0140-6736(20)30251-8Summary Full Text PDF Scopus (8212) Google Scholar has since spread within China to other countries.

A novel coronavirus of zoonotic origin (2019-nCoV) has recently been identified in patients with acute respiratory disease. This virus is genetically similar to SARS and bat SARS-like coronaviruses. The outbreak was initially detected Wuhan, a major city China, but subsequently other provinces China. Travel-associated cases have also reported few countries. Outbreaks health care workers indicate human-to-human transmission. Molecular tests for rapid detection this are urgently needed early...
Introduction Transmission of COVID-19 within families and close contacts accounts for the majority epidemic growth. Community mask wearing, hand washing social distancing are thought to be effective but there is little evidence inform or support community members on risk reduction families. Methods A retrospective cohort study 335 people in 124 with at least one laboratory confirmed case was conducted from 28 February 27 March 2020, Beijing, China. The outcome interest secondary transmission...
We compared the efficacy of medical masks, N95 respirators (fit tested and non fit tested), in health care workers (HCWs).A cluster randomized clinical trial (RCT) 1441 HCWs 15 Beijing hospitals was performed during 2008/2009 winter. Participants wore masks or entire work shift for 4 weeks. Outcomes included respiratory illness (CRI), influenza-like (ILI), laboratory-confirmed virus infection influenza. A convenience no-mask/respirator group 481 from nine compared.The rates CRI (3·9% versus...
Abstract Background Coronavirus disease-2019 (COVID-19) has spread widely throughout the world since end of 2019. Nucleic acid testing (NAT) played an important role in patient diagnosis and management COVID-19. In some circumstances, thermal inactivation at 56°C been recommended to inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) before NAT. However, this procedure could theoretically disrupt nucleic integrity single-stranded RNA virus cause false negatives real-time...
We compared three policy options for the use of medical masks and N95 respirators in healthcare workers (HCWs).A cluster randomized clinical trial 1,669 hospital-based HCWs Beijing, China winter 2009-2010.Participants were to masks, respirators, or targeted while doing high-risk procedures barrier nursing. Outcomes included respiratory illness (CRI) laboratory-confirmed pathogens symptomatic subjects.The rate CRI was highest mask arm (98 572; 17%), followed by (61 516; 11.8%), (42 581; 7.2%)...
With the spread of SARS-CoV-2 worldwide, understanding basic epidemiological parameter values COVID-19 from real-world data in mega-cities is essential for disease prevention and control.To investigate parameters infected cases Beijing, we studied all confirmed close contacts Beijing Jan 1st to Apr 3rd 2020. The virological characteristics were analyzed.A total 602 positive SARS-CoV-2, including 585 patients 17 asymptomatic infections. imported mainly Wuhan initially then abroad. Among...
Abstract Respiratory illness caused by a novel coronavirus (COVID-19) appeared in China during December 2019. Attempting to contain infection, banned travel and from Wuhan city on 23 January implemented national emergency response. Here we evaluate the spread control of epidemic based unique synthesis data including case reports, human movement public health interventions. The shutdown slowed dispersal infection other cities an estimated 2.91 days (95%CI: 2.54-3.29), delaying growth...
The blockchain, with its key characteristics of decentralization, persistence, anonymity, and auditability, has become a solution to overcome the overdependence lack trust for traditional public infrastructure on third-party institutions. Because these characteristics, blockchain is suitable solving certain open problems in service-oriented social network, where unreliability submitted reviews service vendors can cause serious security problems. To solve reviews, this paper first proposes...
The first locally acquired case in the Chinese mainland was reported on May 31, 2023, lagging behind other countries. In this study, we aimed to examine early clinical and epidemiological characteristics of earliest cases Mpox Beijing, China. Additionally, investigated sequence transmission patterns virus (MPXV). We analyzed 37 Beijing from 2023 June 21, 2023. age range subjects 24-51 years. Thirty-six (97.3%) were identified men who have sex with (MSM), 19 (51.4%) tested positive for human...
We compared the efficacy of medical masks (MM) and N95 respirators (N95) in preventing bacterial colonization/infection healthcare workers (HCWs).A cluster randomized clinical trial (RCT) 1441 hospital HCWs to or respirators, 481 control HCWs, was performed Beijing, China, during winter season 2008-2009. Participants were followed for development respiratory illness (CRI). Symptomatic subjects tested Streptococcus pneumoniae, Bordetella pertussis, Chlamydia Mycoplasma pneumoniae Haemophilus...
Alcohol use is a risk factor for the acquisition of human immunodeficiency virus (HIV) among African American men who have sex with (MSM). Mobile phone-based ecological momentary assessments (EMA) could minimize bias due to retrospective recall and thus provide better understanding social structural context alcohol its relationship HIV-related behaviors in this population as well other highly stigmatized populations.We describe study design implementation, feasibility, reactivity,...
The present study aimed to estimate the influenza vaccination coverage rate in Beijing, China, and identify its determinants older younger adults.A survey was conducted among Chinese adults using a self-administered, anonymous questionnaire May-June 2015. main outcome seasonal uptake. Multivariate logistic regression models were performed factors associated with uptake.A total of 7106 participants completed questionnaire. overall 20.6% (95% CI 19.7% 21.5%) 2014/2015 season.
