Vertical transmission is the process of passing an infection or a disease from a parent to a child during pregnancy, childbirth, or breastfeeding. Vertical transmission can have serious consequences for the health and development of the child, as well as for the future generations. Some of the diseases that can be transmitted vertically are HIV/AIDS, syphilis, hepatitis B, rubella, toxoplasmosis, and congenital cytomegalovirus.

In this article, you will learn more about the history, mechanisms, prevention, and treatment of vertical transmission. You will also learn how to protect yourself and your child from these diseases.

A Brief History of Vertical Transmission

The history of vertical transmission is intertwined with the history of medicine and science. Since ancient times, people have been aware of the existence and importance of vertical transmission for their health and survival. They have tried to find ways to prevent or treat vertical transmission by using various methods such as herbal remedies, dietary restrictions, ritual practices, or surgical procedures.

However, it was not until the 19th and 20th centuries that significant advances were made in the fields of microbiology, immunology, obstetrics, pediatrics, and public health to understand and combat vertical transmission. In 1863, Auguste Ambroise Tardieu described the congenital syphilis (a bacterial infection that can cause deformities or death in newborns). In 1883, Max von Pettenkofer discovered the hepatitis B virus (a viral infection that can cause liver damage or cancer in children). In 1941, Norman Gregg discovered the rubella virus (a viral infection that can cause birth defects or miscarriage in pregnant women). In 1981, Arye Rubinstein and James Oleske reported the first cases of pediatric AIDS (a syndrome caused by the human immunodeficiency virus that can impair the immune system and increase the risk of infections or cancers in children).

Since then, many more discoveries and innovations have been made to prevent and treat vertical transmission. Drugs such as antiretrovirals (drugs that inhibit HIV), penicillin (a drug that kills syphilis bacteria), interferon (a drug that stimulates the immune system against hepatitis B virus), and immunoglobulin (a drug that provides antibodies against rubella virus) have been developed to reduce or eliminate the risk of vertical transmission. Tests such as PCR (a test that detects the genetic material of a pathogen), ELISA (a test that detects the presence of antibodies or antigens), TORCH (a test that screens for toxoplasmosis, rubella, cytomegalovirus, and herpes simplex virus), and amniocentesis (a test that samples the amniotic fluid around the fetus) have been developed to diagnose or monitor vertical transmission. Interventions such as cesarean section (a surgical procedure that delivers the baby through an incision in the abdomen), formula feeding (feeding the baby with artificial milk instead of breast milk), and neonatal care (providing medical care for newborns) have been developed to prevent or treat complications caused by vertical transmission.

How to Protect Yourself and Your Child from Vertical Transmission

Vertical transmission can have serious consequences for the health and development of your child, as well as for the future generations. Therefore, it is important to take care of yourself and your child and prevent or treat vertical transmission. Here are some tips and recommendations on how to protect yourself and your child from vertical transmission:

  • Before pregnancy, consult your doctor or health care provider about your health status and any risk factors for vertical transmission. Get tested for any infections or diseases that can be transmitted vertically, such as HIV, syphilis, hepatitis B, rubella, toxoplasmosis, or cytomegalovirus. If you are infected or exposed, get treated or vaccinated as soon as possible. If you are not infected or exposed, get vaccinated against preventable diseases such as rubella or hepatitis B.
  • During pregnancy, follow your doctor’s or health care provider’s advice and attend regular prenatal check-ups. Get tested again for any infections or diseases that can be transmitted vertically, especially in the first and third trimesters. If you are infected or exposed, get treated or monitored as recommended. If you are not infected or exposed, continue to take preventive measures such as avoiding contact with sick people or animals, wearing gloves when handling soil or cat litter, washing hands frequently, and eating well-cooked food.
  • During childbirth, follow your doctor’s or health care provider’s advice and choose the safest delivery method for you and your child. If you are infected with HIV, syphilis, hepatitis B, or herpes simplex virus, you may need a cesarean section to reduce the risk of vertical transmission. If you are infected with other diseases that can be transmitted vertically, you may need antibiotics or antivirals during labor to reduce the risk of vertical transmission. If you are not infected with any diseases that can be transmitted vertically, you can choose a vaginal delivery or a cesarean section depending on your preference and medical condition.
  • After childbirth, follow your doctor’s or health care provider’s advice and take care of yourself and your child. If you are infected with HIV, syphilis, hepatitis B, or herpes simplex virus, you may need to avoid breastfeeding and use formula feeding instead to prevent vertical transmission. If you are infected with other diseases that can be transmitted vertically, you may need to continue treatment or monitoring for yourself and your child. If you are not infected with any diseases that can be transmitted vertically, you can breastfeed your child if you wish and follow the normal immunization schedule for your child.
