ABSTRACT

Objective To understand the prevalence of Toxoplasma gondii infection and its risk factors among healthy blood donation population in Shijiazhuang City,Hebei Province,so as to provide the evidence for developing effective prevention and control measures. Methods A total of 1630 cases of blood donors in Shijiazhuang City were chosen as respondents,and all the respondents were qualified to the standard of blood donation. The antibodies to T. gondii were detected by using ELISA. The in-fection rates of T. gondii in blood donation population were compared between/among different genders,ages,occupations,edu-cation levels,and places of residence. The risk factors for Toxoplasma infection were surveyed with questionnaires. Results A total of 1630 cases of healthy blood donors were investigated,and among which 126 cases were positive in the detection of anti-bodies to T. gondii and the positive rate was 7.73%. The positive rates between/among the different genders,ages,occupations, and education levels were significantly different( χ2 =4.36,13.98,9.71,7.65,respectively,all P 0.05). The questionnaire survey showed that the T. gondii infection was closely related to keeping pets,outside eating frequently,having chafing dish or barbe-cue,sharing cutting board for cooked and uncooked food,and no the habit of washing hands before meals. Conclusions The infection rate of T. gondii is relatively high among the healthy blood donation population in Shijiazhuang region. The cognitive ed-ucation for T. gondii infection and infection monitoring are the keys to avoid the transfusion infection.
