Abstract
In order to investigate the epidemiological situation of intestinal parasite infections in Lao PDR, parasitological surveys were carried out on a national scale including 17 Provinces and the Vientiane Municipality. A total of 29,846 stool specimens were collected from primary schoolchildren in May 2000 June 2002 and examined once with the cellophane thick smear technique. The cumulative egg Positive rate For intestinal helminthes was 61.9%, BV species, the rate for As caris lumbricoides was 34.9%, hookworm 19.1%, Trichuris trichiura 25.8%,Opisthorchis viverrini 10.9%, Taenia spp. 0.6% and Hymenolepis spp. 0.2%. The northern mountainous regions suck as Phongsaly, Huaphan or Saysomboune Province showed higher prevalence(over 70%) of soil- transmitted helminthes. The regions along the Mekong River such as Khammuane, Saravaue or Savannakhet Province showed higher prevalence(over 20%)of fish-borne parasites. On the other hand, Schistosoma mekongi eggs were detected from1.7% of schoolchildren only in Champassak Province, a previously known endemic area. The highest prevalence was noted in Phongsaly Province(96.0%) and the lowest in Bolikhamxay Province(27.5%). An additional smal1-scale survey by cellophane anal swab detected Enterobius vermicularis eggs in 35.7% of 451 schoolchildren aged 6-8 in Khammuane, Vientiane, Champassak Province and the Vientiane Municipality. Meanwhile, the mean blood hemoglobin level of hootrworm-infected children was not lower than that of hookworm-uninfected children, suggesting that nutritional factors are more important than parasite infection per se. Nevertheless, the above results indicate that a nationwide parasite control project is necessary to reduce possible morbidity of parasitic diseases in the country.
