[Investigation on human Toxoplasma gondii infections in Nanchang City in 2014].

Objective: To investigate the endemic situation of human Toxoplasma gondii infection in Nanchang City in 2014 and analyze the influencing factors, so as to provide the evidence for control measures.
Methods: The high-risk population of T. gondii infection in Nanchang City was collected as an experiment group, and a control group was settled with the ratio of 1∶1. The serum tests and epidemiology surveys were conducted simultaneously, and the influencing factors were analyzed.
Results: The total positive rate of human T. gondii was 5.17% (124/2 400) among the whole population in Nanchang City in 2014. The positive rate was 7.50% (90/1 200) in the experiment group and 2.18% (34/1 200) in the control group, and the difference was significant ( χ ² =26.668, P ＜0.05). The results of univariate analysis indicated that different dietary habits and health habits were closely related to the infection of T. gondii ( χ ² =16.522, 64.954, both P ＜0.05). The result of Logistic analysis showed that the risk factors of T. gondii infection were occupation, educational levels, raising cats, contacting animals or raw meat, and eating raw or uncooked beef.
Conclusions: The high risk population of T. gondii infection is the key population of the toxoplasmosis control. Unhealthy dietary and living habits are key influencing factors of toxoplasmosis, and the related health education and surveillance work should be strengthened.
