title: Home Healthcare Program for Soil-Transmitted Helminthiasis in Schoolchildren along the Mekong River Basin.
abstract: BACKGROUND
  Soil-transmitted helminths (STH) are among the most important groups of infectious agents responsible for physical and intellectual growth retardation in children worldwide. Current status is need requiredfor the development of control programs.
  
  
  OBJECTIVE
  To determine the STH infections among the schoolchildren in the Mekong River basin near rural Ubon Ratchathani, Thailand and Champassak, Laos PDR, including their caregiver knowledge and attitude concerning prevention of STH infections.
  
  
  METHODS
  A cross sectional survey was designed as a home healthcare programfrom October 2009 to April 2012. 1,957 fecal samples were collected from children aged 5-12 years in five districts of Ubon Ratchathani province (1,012 fecal samples; Khong Chiam, Si Mueang Mai, Phibun Mangsahan, Sirindhorn, and Pho Sai), Thailand, and one district of Champassak Province (945 fecal samples; Pakse), Lao PDR. Fecal samples were prepared by the modified formalin ethylacetate concentration technique, and determined by light microscope. The knowledge and attitude of children's caregivers concerning prevention of soil-transmitted helminth infections were completed interviewed by semi-structured questionnaires.
  
  
  RESULTS
  The overall intestinal helminth prevalence rate was 11.88%. Classified by species the STHs were as follows: Ascaris lumbricoides (30.9%), Trichuris trichiura (21.7%), and hookworm (20.5%). The highest prevalence was recorded in children aged 9 years and above. The highest prevalence of STH infection was found in the Pakse district of Laos PDR (16.08%). The intensities of infection with A. lumbricoides, T trichiura, and Hookworm were 1.82 ± 0.36, 1.32 ± 0.30, and 1.29 ± 0.32, respectively. 1,077 of caregivers were completed interviewed and found that the caregivers had fair levels of knowledge and attitude regarding soil-transmitted helminthiasis.
  
  
  CONCLUSIONS
  These results suggest that priority should be given to STH eradication, the development of control programs in the Mekong River Basin, and the provision of education about STH to caregivers to reduce the risk of STH infection in their schoolchildren.
