[Clinico-parasitological research in a mixed focus of clonorchiasis and intestinal nematodiasis in Hanamnin Province (the Socialist Republic of Vietnam)].

The authors described the clonorchiasis focus in the Vietnam province at the seaside delta of the Red River where the aforementioned invasion was accompanied with multiple invasions with intestinal nematodes. Clonorchiasis infestation rate was 28.4% ascaridiasis, 50.5%, trichocephaliasis, 21.3% ancylostomiasis, 7.0%. Clonorchiasis invasion was the result of consumed uncooked carp fish in the salad. It was revealed that the fish was reared in the ponds near the settlements and was fed untreated human and animal feces. The meal was more common among the male persons in the presence of the alcohol intake. Clinical symptoms of the mixed clonorchiasis and intestinal nematodiasis invasion was featured by pains, dyspepsia and the asthenoneurotic syndrome.
