Vector-borne viruses, transmitted among humans and animal hosts through bites of vectors such as mosquitoes and ticks,pose a great and ongoing threat to public health and biosafety(Yang et al., 2022).Among them, dengue virus-induced epidemics, have dramatically increased worldwide in recent decades. The report released by the World Health Organization(WHO) at the end of 2023 showed that dengue epidemic globally surged in2023, with the number of reported cases nearing a historical peak.

Science China(Life Sciences) 2014年第6期57卷 647-648页

作者： ZHOU Xiao-Nong national institute of parasitic diseases Chinese Center for Disease Control and Prevention

Schistosomiasis, caused by infections with Schistosoma japonicum, is one of the human parasitic diseases that remains a public health problem throughout the world＇s tropical and subtropical regions. With the sustained efforts for six decades, schistosomiasis has been effectively controlled in China. But in the lake region of the schistosomiasis endemic areas, the disease is still a big burden to some specific population, such as fishmen and boatmen, which hinders the local social-economic development. Currently, due to the low infection intensity in population of endemic areas after implementation of the integrated control strategy with multi-interventions,

Current Status of Soil-transmitted Nematode Infection in China

引用

Biomedical and Environmental Sciences 2008年第2期21卷 173-179页

作者： YING-DAN CHEN LIN-HUA TANG LONG-QI XU national institute of parasitic diseases Chinese Center for Diseases Control and Prevention Shanghai 200025 China

Objective To carry out national surveys for ascertaining the current status and trends of soil-transmitted nematode infections in China, providing scientific basis for further developing control strategies. Methods In 1988-1992 （hereinafter abbreriated as ＂survey in 1990＂）, a stratified cluster random sampling method was used in the survey. In 2001-2004 （hereinafter abbreriated as ＂survey in 2003＂）, in order to compare with the survey in 1990, two-characteristic stratified cluster random sampling method was used and 687 investigation spots were sampled from the 2848 spots selected in the survey in 1990. Kato-Katz thick smear method was used to examine the eggs of soil-transmitted nematodes in fecal samples. Results The prevalence rates were 53.6% and 19.6% for soil-transmitted nematodes, 14.6% and 6.120% for hookworms, 44.6% and 12.7% for Ascaris lumbricoides, 17.4% and 4.630% for Trichuris trichiura in survey 1990 and survey 2003, respectively. The prevalence rates of soil-transmitted nematodes were higher in 13 provinces than the average level in China in the survey in 1990, and higher in 8 provinces than the average level in the survey in 2003. The prevalence of hookworms, Ascaris lumbricoides, Trichuris trichiura and the overall prevalence of soil-transmitted nematodes were higher in females than in males. It is estimated from the results of survey in 2003 that the number of persons with soil-transmitted nematode infections in the country is about 129 million, less than that in the survey in 1990. Conclusion The prevalence of soil-transmitted nematodes has declined considerably but is still relatively high in some provinces and autonomous regions. control activities and socioeconomic development may have contributed to the decreased prevalence.
