RISK FACTORS FOR Opisthorchis viverrini INFECTION IN A CENTRAL PROVINCE, VIETNAM

Tóm tắt

Opisthorchiasis caused by Opisthorchis viverrini is a major public health problem in
the Mekong Basin in South East Asia. This cross-sectional survey was conducted in 2021
in a rural area of Phu Yen province in central Vietnam to investigate the apparent
prevalence of O. viverrini infection in the community and its associated risk factors. A
total of 696 stool samples were collected and examined using the Kato Katz technique.
Risk factors were investigated using a structured questionnaire and the association with
infection was evaluated by univariate and multivariate logistic regression analysis. The
prevalence of O. viverrini infection in the study population determined by stool
examination was 8.2%. Males, the age group of above 60 years, no education, and
consumption of raw fish dishes were significantly associated with Opisthorchiasis in the
area. These findings confirm the presence of O. viverrini in central Vietnam and the
related factors to infection. Intergrated awareness campaigns and control programs should
be implemented in the region to combat this potentially fatal fluke infection.
