Is Spina bifida contagious?

Spina bifida is absolutely not contagious and cannot be spread from person to person through touch, droplets, or any form of social contact. It is a congenital neural tube defect that occurs during fetal development, meaning there is zero risk to family members, caregivers, or friends living with or interacting with someone who has the condition.

What causes Spina bifida?

Spina bifida is a complex condition resulting from the incomplete closure of the neural tube during the first month of pregnancy. It is not caused by an infection, so it cannot be "caught" or transmitted. Research indicates that the development of Spina bifida is multifactorial, involving a combination of genetic predispositions and environmental factors, such as maternal folate deficiency during early pregnancy. Because Spina bifida is a structural developmental issue rather than an infectious disease, there is no biological mechanism for transmission.

Why is there confusion regarding the contagiousness of Spina bifida?

The confusion often stems from a lack of public awareness regarding congenital conditions. Because Spina bifida involves lifelong medical needs—such as the management of hydrocephalus, paralysis, or urinary system complications—some individuals may mistakenly associate these medical requirements with communicable illnesses. It is important to clarify that the complex needs of Spina bifida patients are strictly related to their nervous, skeletal, and muscular systems and pose no public health risk.

Are there environmental triggers to consider?

While Spina bifida is not contagious, certain factors can influence the risk of a pregnancy being affected by this condition. These include:

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


• Medications: Use of certain anti-seizure medications during pregnancy.


• Maternal health: Conditions such as poorly controlled diabetes or obesity.


• Hyperthermia: High maternal body temperature during early pregnancy (e.g., from high fever or sauna use).

Next steps

• Connect with the 207 members of the Spina bifida community at DiseaseMaps.org to share experiences and combat stigma.


• Consult with a genetic counselor to understand familial risks if you are planning a pregnancy.


• Coordinate care with a multidisciplinary team, including a neurosurgeon, urologist, and orthopedist, to manage the systemic effects of Spina bifida effectively.
