The incidence and genotype of endemic C hepatitis in Hanoi female sex workers at the social re-education centre belonging to Hanoi Office of Invalid – Labor – Social, which was determined in a cross-sectional study – had show that: most of female sex workers there acquired almost genotypes of C hepatitis – 1a, 1b, 1ab, 1c, 6, 6a, 9a. The risk of their hepatitis infection was higher in the group of intravenous drug use than in the groups without drug use

A molecular epidemiological analysis of newly isolated strains of EV71 in West Pacific Region was carried out. VP1 region of recently isolated EV71 were sequenced. Phylogenetic analysis had revealed 2 major genogroup B and C. Basing on nucleotid sequences in VP1 region, those 2 genogroups were divided into sub-groups of B1,B2,B3,B4 and C2,C2,C3,C4. North Vietnam isolated EV71 strains and 4 Shanghai isolate EV71 strains had composed a new genogroup belonging to C4 sub-group genes. South Vietnam isolated EV1 strains and Thailand recently isolated EV71 strains had composed special genogroup belonging C1 sub-group genes

A region of 326 bp of mitochondrial cytochrome oxidase 1 (cox1) for Opisthorchis sp sample collected in An My, Tuy An, Phu Yen, was amplified using PCR. Nucleotide sequence of this cox1 fragment was used to comparatively analyzed with that of O. viverrini, strain Khon Kaen, Thailand, and C. sinensis sequences of Opisthorchis sp of Vietnam, China and Korea. The analysis revealed that nucleotide sequences of Opisthorchis sp of Vietnam has absolute homology to O. viverrini strain Khon Kaen, Thai Lan, but difference from C. sinensis originated from Vietnam, China and Korea. Opisthorchis sp of Vietnam isolated in Phu Yen is, thus, molecularly identified as Opisthorchis viverrini. This gives rise to establish a diagnostic approach and aspect of preventive/control for these species

323 patients with hepatitis and cirrhosis (244 males, 89 females admitted into the clinical Institute of Tropical diseases from Jan 2001 to August 2002 were studied on. Result showed that: in Hanoi, hepatitis patients were infected with C hepatitis virus of the types 1a, 1b, 6a. The incidence of various HCV genes was not different in deverse age groups, places, occupations, marital status of the patients, but the differences were noted according to the gender, the education level, the history of drug use and blood transfusion.
