The term “TORCH” is composed of the first letters of the names of various pathogens that cause intrauterine infections. Rubella virus (rubellavirus, R), C is the cytomegalovirus (CMV), H is the herpes simplex virus (herpesvirus, H). Modern medical research has confirmed that women are highly susceptible to infection by rubella virus, cytomegalovirus, herpes simplex virus and other pathogens during pregnancy due to decreased immunity. These pathogens can cause fetal infections through the placenta, resulting in miscarriage, premature birth, congenital malformations of the fetus, as well as newborn infections through the birth canal or breast milk. Intrauterine or neonatal infections caused by these pathogens are called “TORCH syndrome”. Some cases are asymptomatic at birth, but gradually develop mental retardation and visual and hearing impairment as they grow older. Therefore, it is essential to test pregnant women for TORCH-IgM antibodies. If a pregnant woman is infected with rubella virus, it can lead to congenital heart disease, cataract, deafness and other congenital rubella syndrome; if she is infected with CMV, it can lead to fetal mental retardation, hemolytic anemia, microcephaly and anencephaly; if she is infected with herpes simplex virus, it can lead to premature birth and stillbirth, and it is related to the occurrence of cervical cancer in women. In addition, if a pregnant woman comes into contact with ornamental animals such as cats and dogs, or eats food containing Toxoplasma gondii, she may develop Toxoplasma gondii infection, which may lead to hydrocephalus, intracerebral calcification and retinal chorioretinitis. This is why experts recommend that TORCH testing be included in routine preconception and pregnancy screening programs. If the preconception TORCH test is positive, treatment should be actively pursued and pregnancy should not occur until the IgM antibodies are negative. If the infection occurs in the early or middle stages of pregnancy, the pregnant woman should be advised to terminate the pregnancy. If the infection occurs in the late stages of pregnancy, the fetus should be monitored closely by ultrasound or other tests. If the fetus is developing normally, the fetus can be preserved, but the baby must be artificially fed after delivery to prevent neonatal infection through breastfeeding, and the health condition of the newborn should be closely observed; if the fetus is developing abnormally, the pregnancy should be terminated in time. In addition, pregnant women should also pay attention to the following points: increase nutrition to improve muscle resistance; try not to go to public places to avoid respiratory virus infection; strictly prohibit contact with cats, dogs and other ornamental animals to avoid toxoplasmosis infection; do not eat raw or semi-raw food to prevent the occurrence of intestinal parasitic diseases and other infectious diseases of the digestive tract; rubella virus vaccination before pregnancy to avoid rubella infection.
