OBJECTIVE We aimed to determine the burden of bacillary dysentery in China, its cross-regional variations, trends in morbidity and mortality, the causative bacterial species and antimicrobial resistance patterns. METHODS We extracted and integrated governmental statistics and relevant medical literature published from 1991 to 2000. Data were also(More)
BACKGROUND Japanese encephalitis (JE) is presumed to be endemic throughout Asia, yet only a few cases have been reported in tropical Asian countries such as Indonesia, Malaysia and the Philippines. To estimate the true disease burden due to JE in this region, we conducted a prospective, hospital-based surveillance with a catchment population of 599,120(More)
OBJECTIVE To characterize the incidence, epidemiologic features, etiologic agents and sequelae of bacterial meningitis in children under 5 years of age in Nanning, Guangxi. METHODS A population-based surveillance was conducted to evaluate children with signs and symptoms of meningitis. All hospitals, township health centers and village clinics in the(More)
Phase-III vaccine efficacy trials typically employ individually randomized designs intended to ensure that measurements of vaccine protective efficacy reflect only direct vaccine effects. As a result, decisions about introducing newly licensed vaccines into public health programmes often fail to consider the substantially greater protection that may occur(More)
The objective of the study was to identify the protective factors for the rapid decline in the risk of hepatitis A virus (HAV) infection in China between 1990 and 2006. Results of serological follow-up and data on annual hepatitis A incidence were analysed and correlated with economic growth and HAV vaccine output during the same period. In conclusion, both(More)
BACKGROUND To assess the incidence and economic burden of rotavirus diarrhea and the potential cost-effectiveness of a rotavirus immunization program in rural Zhengding County in Hebei Province, China. METHODS Population-based surveillance was conducted during the peak season for diarrhea among children who were <5 years of age in Zhengding County from 14(More)
Live, attenuated hepatitis A vaccines are used widely in China but there is uncertainty regarding the persistence of vaccine-induced anti-HAV antibodies after single dose and booster dose administrated at month 12. A large scale clinical trial to evaluate the live, attenuated hepatitis A vaccine was conducted in Hebei province between 1996 and 1999. Five(More)
We traced 85 Japanese encephalitis (JE) patients, 6-27 years after hospitalizations. The first control group was made up of 73 non-JE encephalitis patients 6-27 years previously, whereas the second control group was made up 78 neighborhood residents, matched to the 78 surviving JE cases by age, sex, and residence. All subjects were examined with neurologic(More)
In 2002, population- and treatment center-based surveillance was used to study the disease burden of shigellosis in rural Hebei Province in the People's Republic of China. A total of 10,105 children with diarrhea or dysentery were enrolled. Infants were treated most frequently for diarrhea (1,388/1,000/year) followed by children < or = 5 years old(More)
OBJECTIVE To determine the burden of enteric fever through trends in morbidity and mortality, bacterial species and antimicrobial resistance in Guangxi, a southern, subtropical, coastal province of China with a disproportionally large burden of enteric fever. METHODS Data on morbidity and mortality caused by enteric fever between 1994 and 2004 were(More)
