Question Congenital toxoplasmosis is a dangerous fetal infection. Why is routine screening for Toxoplasma gondii infection during pregnancy not available for most Canadians? Answer Low prevalence of the infection, high cost associated with testing, low sensitivity of screening tests, false-positive test results, and limitations of treatment effectiveness are all cited as reasons for not routinely screening for T gondii infection in Canada. Currently, screening for the detection of T gondii is only performed in Nunavik and other parts of northern Quebec owing to the high prevalence of infection in this region. Congenital toxoplasmosis causes neurologic or ocular disease (leading to blindness), as well as cardiac and cerebral anomalies.
先天性弓形虫病是一种危险的胎儿感染疾病。为什么大多数加拿大人在孕期无法进行常规的弓形虫感染筛查？答案：感染率低、检测成本高、筛查测试灵敏度低、测试结果呈假阳性以及治疗效果有限，这些都被列为加拿大不进行常规弓形虫感染筛查的原因。目前，由于努纳维克和魁北克省北部其他地区感染率高，仅在这些地区进行弓形虫检测筛查。先天性弓形虫病会导致神经或眼部疾病（导致失明），以及心脏和脑部异常。
