Abstract:

Objective To investigate the Clonorchis sinensis infection and related knowledge, attitudes, and practice (KAP) in the population in Nanning City for evidences to plan targeted prevention and control measures. Methods Two to three counties (districts) in Nanning area were annually selected as surveillance sites for clonorchiasis from 2021 to 2023. Then 1 000 people were respectively included from each monitoring site every year by stratified cluster sampling method to undergo detection of clonorchiasis eggs with modified Kato-Katz thick smears (one stool and two tests). Finally, 150 subjects were randomly selected for questionnaire survey. Results A total of 8 058 people were investigated from 2021 to 2023, in whom 1 534 were positive for Clonorchis sinensis. The total infection rate was 19.04% and classification of infection degree is mainly mild infection (85.46%, 1 311/1 534). The difference of infection rate in each counties (districts) was statistically significant (χ2=757.968, P<0.05). The top 3 infection rates were in Jiangnan District (41.16%, 417/1 013), Qingxiu District (36.97%, 373/1 009) and Xixiangtang District (15.30%, 153/1 000). The infection rate was 28.07% (1 101/3 922) for males and 10.47% (433/4 136) for females, and the highest in population aged 50-59 years (28.33%, 440/1 553). By educational background and occupation, the highest infection rate was seen in population of junior middle school (28.15%, 908/3 226) and farmers (26.02%, 1 368/5 258). There were significant differences in infection rate among different genders, age groups, education levels and occupations (χ2=404.732, 691.044, 352.794, 695.679, all P<0.05). The overall knowledge awareness rate, attitude accuracy rate and behavior accuracy rate were 80.08% (961/1 200), 72.75% (873/1 200) and 69.42% (833/1 200), respectively. The KAP was negatively correlated with Clonorchis sinensis infection [OR=0.51, 95% CI: (0.35, 0.74); OR=0.42, 95% CI: (0.29, 0.62) ; OR=0.27, 95% CI: (0.18, 0.40), respectively]. Conclusion The overall infection level of Clonorchis sinensis in Nanning city remains relatively higher, yet the infection is in mild degree, and the level of KAP towards Clonorchis sinensis infection needs improving. It is recommended to carry out comprehensive control measures combining health education and drug treatment to reduce the infection rate of the population.
