Our aim has been to provide an authoritative overview of the current situation and most importantly to identifyareasthatneedgreatereffort.Ourhighlymotivatedguesteditors, Xiao-Nong Zhou (National Institute of Parasitic Diseases, Chinese Center forDiseaseControlandPrevention,Shanghai,People’sRepublicofChina), RobertBergquist(Ingerod,Brastad,Sweden),RemigioOlveda(Department ofHealth,ResearchInstituteofTropicalMedicine,Manila,Philippines)and Ju¨rg Utzinger (Department of Epidemiology and Public Health, Swiss Tropical and Public Health Institute, Basel, Switzerland), have used their considerableskillsandknowledgetoensurethatthesevolumesprovidean exceptionalinsightintothecurrentsituation.Bybringingtogetherapanel of international experts and leaders in research and control, they have succeededinprovidingacomprehensiveinformationsourceforthisimpor- tanttopic.Weverymuchhopethatthetwovolumeswillfurtherstimulate others to participate and help control some of these very debilitating parasiticinfections. DAVIDROLLINSONANDSIMONI.HAY xvii PREFACE These two volumes of Advances in Parasitology cover the major parasitic helminths in Southeast Asia and the People’s Republic of China (P.R.China).Thereasonsforpublishingthesevolumes,Ibelieve,arethe remarkable importance of these parasites in almost every country of the region, and the great progress achieved in the past few decades on researchandcontrolofthediseasesinsomeofthecountries. It is well recognised that health bears a critical contribution to the socialandeconomicwell-beingsofindividualsandcommunities.Numer- ous examples reveal that poverty and ill-health interact with each other bothasacauseandasaneffect,whichiswhySoutheastAsiahasbeenone ofafewmostimportantendemicregionsforthehelminthsandaccounts foralargeproportionoftheglobaldiseaseburden. Referredtointhevolumesarehelminthiases,whichareeitherwater- borne, food-borne, mosquito-borne or soil-transmitted. They have had, andcontinuetohave,adramaticimpactonthehealthofthepeopleandof livestock.Thechaptersprovideupdatedinformationondiseaseepidemi- ology, pathogenesis and control, and they also highlight insights of par- ticular concern. For instance, the socioeconomically marginalised population groups in Southeast Asia and southern P.R. China are often ethnic minorities, whose characteristic cultural, social and behavioural risk factors are contributory to the prevalence of the diseases. Drug development, vaccine research and application of geospatial health techniques are comprehensively reviewed. The health metrics issue in parasiticinfectionsisalsodiscussed,asthemeasurementofthemorbidity has long been an unsolved issue due to their chronic, insidious and frequently asymptomatic features. Application of biotechnology in the research of genomics, proteomics, transcriptomics and metabonomics is providing extraordinary approaches to a better understanding of the biology of the helminths and their interactions with their hosts. People expectfurtherdevelopmentofnoveltoolsforcontrolinterventionsbased on the ‘‘–omics’’ information. Knowledge gaps are highlighted and researchneedsaredescribedinanumberofchapters.

Even though the condi- tionsarestillchallenging,thisisthetimetotakeactionincombatingthese diseasesbecause we now have the powerful and cost-effective tools and tested strategies for most of the infections. Furthermore, the socioeco- nomic development, including poverty alleviation in the poor popula- tions, is improving access to safe water, better sanitation and housing, which are conducive to prevent the infections. It is indeed encouraging thattheneglectedtropicaldiseasesarebackinpolicyfocusafterdecades ofsubstantialneglect. As a huge public health problem in P.R. China, lymphatic filariasis was rampant in most of the populated provinces. Due to the strenuous efforts over the past five decades, the country has declared the national eliminationofthediseasewithWHO’scertificationin2008.Therefore,we have reasons to believe that with a dedicated political commitment and available resources in all the countries, people will be able to effectively controlthediseases,ifnoteliminatetheminaforeseeableperiodoftime.
