Is Congenital Insensitivity To Pain With Anhidrosis (CIPA) contagious?

Congenital Insensitivity to Pain with Anhidrosis (CIPA) is a rare genetic disorder and is absolutely not contagious; it cannot be spread through touch, social interaction, or environmental exposure. It is caused strictly by mutations in the NTRK1 gene, meaning it is inherited and present from birth rather than caused by any infectious agent.

What is the actual cause of Congenital Insensitivity to Pain with Anhidrosis (CIPA)?

Congenital Insensitivity to Pain with Anhidrosis (CIPA), also known as Hereditary Sensory and Autonomic Neuropathy type IV (HSAN IV), is an autosomal recessive genetic condition. This means an individual must inherit two copies of the mutated NTRK1 gene—one from each parent—to manifest the disease. It is not caused by viruses, bacteria, or external environmental pathogens.

Why is there confusion regarding the contagion of CIPA?

Because Congenital Insensitivity to Pain with Anhidrosis (CIPA) involves complex symptoms like recurrent fevers and skin lesions, individuals unfamiliar with the condition may mistakenly fear it is infectious. However, the fevers in Congenital Insensitivity to Pain with Anhidrosis (CIPA) are caused by the body's inability to sweat (anhidrosis) to regulate temperature, not by an infection. The skin lesions often result from an inability to feel pain, leading to accidental self-injury or infection of wounds that go unnoticed.

Is it safe to interact with someone who has CIPA?

There is zero risk in living with, touching, or being near someone diagnosed with Congenital Insensitivity to Pain with Anhidrosis (CIPA). You cannot "catch" the condition through any form of contact. Understanding the nature of this disorder is vital to reducing the social stigma that families often face.

Key facts about CIPA transmission and triggers:

• Genetics: It follows an autosomal recessive inheritance pattern; parents are typically asymptomatic carriers.


• Pathology: Symptoms are due to the failure of specific nerve cells to develop properly in the peripheral nervous system.


• Environmental Triggers: While the disease is not caused by the environment, high temperatures are dangerous for patients because they cannot sweat, leading to severe hyperpyrexia (overheating).

Next steps

• Consult with a clinical geneticist to understand family inheritance patterns if you or a family member have received a diagnosis.


• Connect with the Congenital Insensitivity to Pain with Anhidrosis (CIPA) community at DiseaseMaps.org to share experiences with others.


• Work with a specialized team, including dermatologists and neurologists, to manage skin health and temperature regulation.
