2342 male military recruits from different parts of Norway were selected for serological screening with the dye test or the IgG-indirect fluorescent antibody test. The highest frequency of toxoplasma antibodies was observed in the south-western areas (27%), whereas the prevalence was found to be as low as 2% in the northermost areas of the country. On the basis of the prevalence values obtained in the different counties, the incidence rates for acquired infections in the pregnant population have been calculated. The annual incidence in Norway was estimated to be 4 0/00 and the incidence of congenital toxoplasmosis would be maximally 2 0/00 (or about 110 cases/year).
从挪威不同地区选取了2342名男性新兵，用染色试验或IgG间接荧光抗体试验进行血清学筛查。弓形虫抗体的最高频率在西南部地区观察到（27%），而在该国最北部地区患病率低至2%。根据在不同县获得的患病率值，计算了孕妇群体中获得性感染的发病率。挪威的年发病率估计为4‰，先天性弓形虫病的发病率最高为2‰（或约每年110例）。
