Is Anencephaly contagious?

Anencephaly is not contagious, and there is absolutely no risk of transmission through touch, proximity, or caregiving. It is a severe congenital structural anomaly of the fetal brain and skull, not an infectious disease, and it cannot be spread to other family members or the public under any circumstances.

What is the actual cause of Anencephaly?

Anencephaly is a neural tube defect that occurs during the very early stages of embryonic development, typically within the first 28 days after conception. It results from the failure of the cephalic (head) end of the neural tube to close properly. While the exact cause is often multifactorial, it is not caused by viruses, bacteria, or any external infection. Research suggests that a combination of genetic factors and environmental influences, such as maternal folate deficiency, plays a significant role in the development of Anencephaly.

Why is there confusion regarding contagion?

Because Anencephaly is a rare and often misunderstood condition, some people may mistakenly associate it with infectious diseases due to a lack of public awareness. It is important to emphasize that there is no biological pathway for Anencephaly to be passed from person to person. Living with, holding, or providing comfort to an infant affected by Anencephaly poses zero health risk to parents, caregivers, or other children.

What are the known risk factors for Anencephaly?

While the condition is not contagious, medical researchers have identified several factors that may increase the risk of a pregnancy being affected by Anencephaly:

• Maternal Folate Deficiency: Insufficient intake of folic acid before and during early pregnancy.


• Genetic Predisposition: A family history of neural tube defects slightly increases the risk.


• Maternal Health Conditions: Pre-existing diabetes or the use of certain anti-seizure medications during early pregnancy.


• Environmental Exposures: High maternal body temperature (such as from fever or hot tubs) in early pregnancy.

Addressing stigma and misconceptions

Families facing a diagnosis of Anencephaly often experience social isolation due to unfounded fears or stigma. It is vital to reiterate that Anencephaly is an internal developmental process. With 31 members on DiseaseMaps.org sharing their experiences, our community stands as a testament to the need for compassion and scientific accuracy over fear.

Next steps

• Consult with a genetic counselor to discuss recurrence risks for future pregnancies.


• Speak with a maternal-fetal medicine specialist for guidance on prenatal nutrition and folic acid supplementation.


• Connect with the DiseaseMaps.org community to share experiences with others who understand the journey of Anencephaly.


• Seek support from perinatal hospice services to navigate the emotional complexities of the diagnosis.
