KHẢO SÁT TỶ LỆ HUYẾT THANH DƯƠNG TÍNH VỚI ẤU TRÙNG TOXOCARA SPP. VÀ CÁC YẾU TỐ LIÊN QUAN Ở NHÂN VIÊN CỦA CÔNG TY THÉP NĂM 2024

Abstract

Toxocariasis is a parasitic disease that can be silently transmitted through contact with eggs containing dog/cat roundworm larvae. Although widely recognized in Viet Nam, data on industrial workers with specific environmental risks are still very limited, creating a gap that needs to be surveyed. Objectives: To determine the rate of seropositivity for Toxocara spp. in workers of two large steel factories; To analyze factors related to seropositivity including knowledge, behavior, symptoms and paraclinical indicators. Subjects and methods: A descriptive cross-sectional study was conducted from 12/2024 to 05/2025 with 395 workers undergoing periodic health check-ups. Demographic data, knowledge, behavior, symptoms and paraclinical results (eosinophil, ALT, AST) were collected through interviews and tests. Results: The rate of seropositivity was 27.6% (109/395). Factors that were statistically significant with positive serum results were frequent consumption of raw vegetables (p=0.01), not washing hands after contact with dogs/cats (p=0.013), irregular cleaning of cages (p=0.004), direct handling of dog/cat feces (p=0.021) and not regularly deworming pets (p=0.002). There was no association between positive serum and gender, age, type of dog/cat raising, habit of washing hands before eating, liver enzymes ALT/AST and total white blood cells (WBC). Conclusion: The seropositivity rate for Toxocara spp. in the worker group was recorded at a high level compared to domestic studies. Lack of disease prevention knowledge and the habit of eating raw vegetables were prominent risk factors.
