There were large outbreaks of hand, foot, and mouth disease in both 2008 2009 China.Using the national surveillance data since 2 May 2008, we summarized epidemiologic characteristics recent outbreaks. Using a susceptible-infectious-recovered transmission model, evaluated transmissibility potential risk factors.Children ages 1.0 to 2.9 years most susceptible (odds ratios [OR] >2.3 as compared with other age-groups). Infant cases had highest incidences severe (ORs >1.4) death >2.4), well...
Background Over the past two decades, major epidemics of hand, foot, and mouth disease (HFMD) have occurred throughout most West-Pacific Region countries, causing thousands deaths among children. However, few studies examined potential determinants incidence HFMD. Methods Reported HFMD cases from 2912 counties in China were obtained for May 2008. The monthly cumulative was calculated children aged 9 years younger. Child population density (CPD) six climate factors (average-temperature [AT],...
Dengue is endemic in more than 100 countries, mainly tropical and subtropical regions, the incidence has increased 30-fold past 50 years. The situation of dengue China become severe, with an unprecedented outbreak hitting south 2014. Building a early warning system therefore urgent necessary for timely effective response.In study we developed time series Poisson multivariate regression model using imported cases, local minimum temperature accumulative precipitation to predict occurrence four...
The Hand-Foot-Mouth Disease (HFMD) is the most common infectious disease in China, its total incidence being around 500,000 ~1,000,000 cases per year. composite space-time variation result of underlining attribute mechanisms that could provide clues about physiologic and demographic determinants transmission also guide appropriate allocation medical resources to control disease. HFMD were aggregated into 1456 counties during a period 11 months. Suspected climate attributes recorded monthly...
To analyse the epidemiology of measles in China and determine progress made towards national elimination disease.We analysed surveillance data - on age, sex, residence vaccination status each case corresponding outcome, dates onset report laboratory results collected between January 2005 October 2013.Between 2013, 596 391 cases 368 measles-related deaths were reported China. Annual incidence, per 100 000 population, decreased from 9.95 2008 to 0.46 2012 but then rose more than 1.96 2013. The...
Introduction Each year there are approximately 390 million dengue infections worldwide. Weather variables have a significant impact on the transmission of Dengue Fever (DF), mosquito borne viral disease. DF in mainland China is characterized as an imported Hence it necessary to explore roles cases, density and climate variability China. The study was identify relationship between occurrence possible risk factors develop predicting model for dengue's control prevention purpose. Methodology...
Using an elimination strategy, Hong Kong was able to minimise COVID-19 mortality in 2020 and 2021, but a large epidemic caused by the Omicron variant occurred 2022. We aimed estimate overall, age-, sex-, period- cause-specific excess 2022 compare laboratory-confirmed mortality. used negative binomial regression analysis model time series of weekly all-cause deaths from 2010 2021 predict number against counterfactual baselines projected trends absence pandemic. The estimated were compared...
SUMMARY We examined the spatial distribution pattern and meteorological drivers of dengue fever (DF) in Guangdong Province, China. Annual incidence DF was calculated for each county between 2005 2011 geographical using Moran's I statistic excess risk maps. A time-stratified case-crossover study used to investigate short-term relationship factors Southern Oscillation Index (SOI). High-epidemic areas were restricted Pearl River Delta region Han region, significant from 2006 2009 2011. Daily...
Due to growing activities of avian influenza, more attention should be paid influenza virus infections. Global summaries or national reports lack data on epidemiological patterns influenza. A descriptive analysis outbreaks from 2018 2022 was conducted, particularly fowl infections, human and sequence alterations. The number infection in the first half highest level five-year period. Countries regions could reliably classified into three clusters according activity scores, with 60.0%...
In 2006, China set a goal of measles elimination by 2012. To describe progress toward this goal, we reviewed relevant policies and strategies analyzed national data for 2000-2009. response to implementation these strategies, including increased routine vaccination coverage province-specific supplementary immunization activities (SIAs), reported incidence decreased historically low level 39.5 cases per million in 2009. A synchronized nationwide SIA was scheduled 2010 further decrease...
Acute diarrhea is a leading cause of childhood morbidity and mortality worldwide, but there have been few reports on the causative viruses associated with acute among outpatient children in developing countries. This study was conducted to identify viral agents southeastern China.Eight hundred eleven 5 years or younger were enrolled. Five enteric determined by enzyme-linked immunosorbent assay multiplex reverse transcription-polymerase chain reaction for each stool specimen.At least 1 virus...
During May-August 2013, a malaria outbreak comprising 874 persons in Shanglin County, China, was detected among 4,052 returning from overseas. Ghana the predominant destination country, and 92.3% of malarial infections occurred gold miners. Preventive measures should be enhanced for high-risk occupations traveling to malaria-endemic countries.
SUMMARY The monthly and annual incidence of haemorrhagic fever with renal syndrome (HFRS) in China for 2004–2009 was analysed conjunction associated geographical demographic data. We applied the seasonal autoregressive integrated moving average (SARIMA) model to fit forecast HFRS China. endemic most regions except Hainan Province. There a high risk infection male farmers aged 30–50 years. fitted SARIMA(0,1,1)(0,1,1) 12 had root-mean-square-error criterion 0·0133 that indicated accurate...
Acute diarrhea leads to a substantial disease burden among the elderly worldwide. However, in context of increasingly aging trend China, prevalence etiological agents diarrheal patients was undetermined. This study aimed explore major enteropathogens acute outpatients older than 65 years and also epidemiological features pathogens. Demographic clinical data for were collected from 213 participating hospitals 2009 2014. Stool specimens tested 13 enteric viruses bacteria. The proportion...
The aim of the study was to describe spatial and temporal patterns dengue in Guangdong for 1978 2010. Time series analysis performed using data on annual incidence province 1978-2010. Annual average incidences each city were mapped 4 periods by geographical information system (GIS). Hot spot used identify cases 2005-2010 CrimeStat III software. had fallen steadily from time a random sequence without regularity with no fixed cycle. geographic range fever expanded Cases mostly concentrated...
