Epidemiological investigation on hydatidosis in students of Guluo Tibetan Autonomous Prefecture in Qinghai Province

Abstract

Abstract:

To understand the prevalence of hydatidosis in students of Guluo Tibetan Autonomous Prefecture, Qinghai Province, (referred to as Guluo Prefecture hereafter), ELISA and B-ultrasonography were performed in students of 6 to 19-year from 50 schools in 40 towns of 6 counties in the Prefecture in 2012. The results showed that the hydatidosis prevalence by ultrasound was 2.9% (247/8 597) and the positive rate of serum antibody was 16.1% (1 218/7 552) among the students. Both indices were highest in Dari county (5.6%, 124/2 225; 23.0%, 428/1 861, respectively), and were significantly different among counties (χ² = 228.314 and 100.449, P < 0.05). The prevalence in males and females was 2.7% (116/4 232) and 3.0% (131/4 365), respectively (P > 0.05). The serum antibody positive rates in males and females were 15.7% (579/3 698) and 16.6% (639/3 854), respectively (P > 0.05). Among different age groups, the group of 13-19 years had the highest prevalence (7.6%, 57/750), while the group of 8-9 years had the highest serum antibody positive rate (18.5%, 214/1 159), both showed significant difference among age groups (χ² = 75.088, 27.994, P < 0.05). These results show a high prevalence of hydatidosis in Guluo Prefecture.
