TORCH

acronym

/tɔːtʃ/

Infectious Diseases

Definition

1.The classic congenital (intrauterine) infections.

Expansion

  1. TToxoplasmosis intracranial calcification, chorioretinitis
  2. OOther syphilis, VZV, parvovirus B19, HIV, Zika
  3. RRubella cataracts, deafness, cardiac defects
  4. CCytomegalovirus the commonest; deafness, microcephaly

Notes

The TORCH infections cross the placenta (or are acquired at birth) and share a vocabulary of harm: growth restriction, rash, hepatosplenomegaly, sensorineural deafness and CNS involvement.

The "Other" bucket keeps growing — syphilis deserves its own letter in many versions, and Zika is the modern addition.

Origin

A torch held to the womb — the screen for infections passed from mother to child.
