The group of the most common congenital infections are referred to by the mnemonic TORCH or STORCH. They usually cause mild maternal morbidity but are related to serious fetal consequences 4.
In cases where no serological, microbiological or immunological evidence of infection can be identified the term pseudo-TORCH has been used 5.

- O: other (e.g. syphilis, varicella-zoster, parvovirus B19)
