Is Transverse myelitis contagious?

Transverse myelitis is not contagious and cannot be spread from person to person through touch, saliva, or any other form of physical contact. It is an inflammatory disorder of the spinal cord that is caused by immune system dysfunction, not by an infectious pathogen being transmitted between individuals.

Why is Transverse myelitis not contagious?

Transverse myelitis occurs when the immune system mistakenly attacks the protective myelin sheath surrounding the nerve fibers of the spinal cord. Because the condition is rooted in an internal immune-mediated process, there is no virus, bacteria, or fungus to "catch." You cannot contract Transverse myelitis by living with, caring for, or being in close proximity to someone diagnosed with the condition. It is a non-communicable disease, meaning it does not spread through air, water, or personal interaction.

What causes Transverse myelitis?

While the exact trigger for Transverse myelitis is often unknown (idiopathic), medical researchers have identified several underlying mechanisms that contribute to the inflammation of the spinal cord. It is frequently categorized as an autoimmune or post-infectious inflammatory disorder. Potential triggers include:

• Autoimmune reactions: The body’s immune system mistakenly targets the spinal cord, similar to the processes seen in multiple sclerosis or neuromyelitis optica.


• Post-viral inflammation: Sometimes, the immune system becomes overactive while fighting off a common viral infection (such as varicella-zoster or enteroviruses), and this immune response inadvertently causes damage to the spinal cord.


• Systemic inflammatory conditions: Certain connective tissue diseases or sarcoidosis can lead to the spinal cord inflammation characteristic of Transverse myelitis.


• Vaccinations: While very rare, some cases have been associated with immune responses following immunization, though the risk is significantly lower than the risks associated with the infections themselves.

Why do people mistakenly think Transverse myelitis is contagious?

The misconception that Transverse myelitis is contagious often stems from its occasional association with viral infections. Because a patient may experience symptoms shortly after having a cold or a flu-like illness, family members or the public may incorrectly assume the patient is "contagious" because they were recently ill. However, it is the patient's own internal immune response—not the original virus—that causes the spinal cord inflammation. It is vital to combat the stigma surrounding Transverse myelitis, as social isolation can worsen the depression and anxiety that often accompany this challenging diagnosis.

How does the DiseaseMaps community support patients?

Living with a rare condition like Transverse myelitis can feel isolating, especially when others do not understand the nature of the disease. Currently, 798 people with Transverse myelitis have joined the DiseaseMaps community to share their experiences and support one another. Connecting with others who understand the reality of muscle weakness, fatigue, and the challenges of managing bowel or bladder function can be a powerful tool for emotional well-being.

Next steps

• Consult a specialized neurologist to discuss your specific symptoms and ongoing management strategies like physical or occupational therapy.


• Join the DiseaseMaps community to connect with other families and patients who understand the daily challenges of living with Transverse myelitis.


• Reach out to a clinical psychologist who specializes in chronic illness to address the mental health aspects of the condition, such as depression or anxiety.


• Keep a detailed log of your symptoms and potential triggers to share with your healthcare team during routine check-ups.
