As reported by the World Health Organization, a novel coronavirus (2019-nCoV) was identified as causative virus of Wuhan pneumonia unknown etiology Chinese authorities on 7 January, 2020. The named severe acute respiratory syndrome 2 (SARS-CoV-2) International Committee Taxonomy Viruses 11 February, This study aimed to develop mathematical model for calculating transmissibility virus.
Abstract As reported by the World Health Organization, a novel coronavirus (2019-nCoV) was identified as causative virus of Wuhan pneumonia unknown etiology Chinese authorities on 7 January, 2020. In this study, we developed Bats-Hosts-Reservoir-People transmission network model for simulating potential from infection source (probable be bats) to human infection. Since Bats-Hosts-Reservoir hard explore clearly and public concerns were focusing seafood market (reservoir) people, simplified...
Abstract Here we report a case study of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak event during bus trips an index patient in Hunan Province, China. This retrospective investigation suggests potential airborne transmission SARS-CoV-2 and the possibility superspreading events certain close contact closed space settings, which should be taken into account when control strategies are planned.
Abstract The coronavirus disease 2019 (COVID-19) pandemic, along with the implementation of public health and social measures (PHSMs), have markedly reshaped infectious transmission dynamics. We analysed impact PHSMs on 24 notifiable diseases (NIDs) in Chinese mainland, using time series models to forecast trends without or pandemic. Our findings revealed distinct seasonal patterns NID incidence, respiratory showing greatest response PHSMs, while bloodborne sexually transmitted responded...
Abstract Background The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, also called 2019-nCoV) causes different morbidity risks to individuals in age groups. This study attempts quantify the age-specific transmissibility using a mathematical model. Methods An epidemiological model with five compartments (susceptible–exposed–symptomatic–asymptomatic–recovered/removed [SEIAR]) was developed based on observed transmission features. Coronavirus disease 2019...
Before herd immunity against Coronavirus disease 2019 (COVID-19) is achieved by mass vaccination, science-based guidelines for non-pharmaceutical interventions are urgently needed to reopen megacities. This study integrated massive mobile phone tracking records, census data and building characteristics into a spatially explicit agent-based model simulate COVID-19 spread among 11.2 million individuals living in Shenzhen City, China. After validation local epidemiological observations, the was...
Abstract With the advent of climate change and 5 G era, online communities are increasingly becoming main medium for information dissemination after emergencies such as natural disasters. The widespread negative may generate cyber violence or lead to serious adverse psychological outcomes. This study considered a disaster event involving avoidable deaths child casualties an example identify emotional contagion conduct simulation interventions. Data about aftermath 8·13 flash flood in...
Mpox is an emerging infectious disease that now a global hazard. The strategies for preventing and controlling mpox should be further investigated in terms of transmission characteristics, infection risk among different populations, ideal therapeutic approaches.A multi-group dynamic model was used to quantify the transmissibility mpox. We analyzed from men who have sex with (MSM) non-MSM evaluated effects three intervention measures, including community-based prevention, early detection,...
Abstract This study attempts to figure out the seasonality of transmissibility hand, foot and mouth disease (HFMD). A mathematical model was established calculate based on reported data for HFMD in Xiamen City, China from 2014 2018. The measured by effective reproduction number ( R eff ) order evaluate seasonal characteristics HFMD. total 43 659 cases were Xiamen, period median annual incidence 221.87 per 100 000 persons (range: 167.98/100,000–283.34/100 000). had a great fitting effect with...
After the first national-scale outbreak of Hand, foot, and mouth disease (HFMD) in China, a national surveillance network was established. Here we described epidemiology pathogenic profile HFMD impact EV-A71 vaccination on pathogen spectrum enteroviruses southeastern Chinese city Nanchang during 2010-2019. A total 7,951 cases from sentinel hospitals were included, which 4,800 EV-positive (60.4%) identified by real-time RT-PCR. During 2010-2012, enterovirus 71 (EV-A71) main causative agent...
Corona virus disease 2019 (COVID-19) has exerted a profound adverse impact on human health. Studies have demonstrated that aerosol transmission is one of the major routes severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Pathogenic microorganisms such as SARS-CoV-2 can survive in air and cause widespread infection among people. Early monitoring pathogenic microorganism atmosphere accurate epidemic prediction are frontier guarantee for preventing large-scale outbreaks. Monitoring...
Tengchong County was one of the counties located at China-Myanmar border with high malaria incidence in previous decades. As pilot county for elimination area, is aiming to be first achieve goal. A cross-sectional entomological survey carried out evaluate feasibility approach and assess receptivity reintroduction. Light traps associated live baits were used investigate abundance adult mosquitoes nine villages County. set collect both human houses cowsheds from dusk till dawn each site. total...
Abstract Acute haemorrhagic conjunctivitis (AHC) outbreaks are reported frequently in China. However, the transmissibility of AHC remains unclear. This study aimed to calculate disease with and without interventions. An outbreak dataset from January 2007 December 2016 different schools was built Hunan Province. A Susceptible-Infectious-Recovered (SIR) model adopted effective reproduction number ( R eff ) AHC. divided into two parts unc con where represent uncontrolled controlled ,...
Reaching optimal vaccination rates is an essential public health strategy to control the coronavirus disease 2019 (COVID-19) pandemic. This study aimed simulate by developing age-specific model based on current transmission patterns of COVID-19 in Wuhan City, China.We collected two indicators COVID-19, including illness onset data and age confirmed case from December 2, 2019, March 16, 2020. The reported cases were divided into four groups: group 1, ≤ 14 years old; 15 44 3, 64 4, ≥ 65 old....
This study aimed to investigate the spatial distribution and patterns of multimorbidity among elderly in China. Data on occurrence 14 chronic diseases were collected for 9710 participants 2015 waves China Health Retirement Longitudinal Study (CHARLS). Web graph, Apriori algorithm, age-adjusted Charlson comorbidity index (AAC), Spatial autocorrelation used perform analysis. The prevalence rate was estimated as 49.64% Three major identified: [Asthma/Chronic lungs diseases]: (Support (S) =...
