1974年Nahmias根据胎儿,新生儿感染的病原体有弓形体属、风疹、巨细胞病毒及单纯疱疹,为了便于记忆取每个病原体外文第一字母缩写成TORCH感染。在先天性感染中,巨细胞病毒乃是最常见的病原体,然而,TORCH并不能反映出病原体发病率的多少;另外,又发现了一些新的病原体,因而按发病率多少缩写成CROTCHS—即巨细胞病毒、风疹、其它、弓形属、柯萨奇、单纯疱疹及梅毒。迄今,对其他病原体仍没有完全了解。Ledand等将<6月的381例婴儿给予TORCH筛查85％仅分析一份血清标本,仅9％进行随访,在初次滴定抗体升高的32名中仅8人(占25％)有恢复期抗体血清的资料。显然,即便是TORCH筛查,
In 1974 Nahmias according to the fetus according to the fetus, neonatal infections with Toxoplasma gondii, rubella, cytomegalovirus and herpes simplex, in order to facilitate the memory of each pathogen foreign initials abbreviated TORCH infection. In congenital infection, cytomegalovirus is the most common pathogen, however, TORCH does not reflect the incidence of pathogens; in addition, we found some new pathogens, which according to the incidence of abbreviated as CROTCHS - that is, Cytomegalovirus, Rubella, Other, Toxoplasma, Coxsackie, Herpes Simplex and Syphilis. To date, other pathogens are still not fully understood. Ledand, et al. Tailor 381 infants in <85 months of June 85% of patients analyzed only one serum sample, only 9% followed up, and only 8 of 32 (25%) had an initial titration antibody recovery Antibody serum information. Obviously, even TORCH screening,
