Is Cyclic Neutropenia contagious?

Cyclic Neutropenia is not a contagious disease and cannot be spread through physical contact, respiratory droplets, or any other form of person-to-person transmission. It is a rare, inherited hematological disorder, meaning it is caused by genetic mutations rather than an infectious agent like a virus or bacteria.

What causes Cyclic Neutropenia?

Cyclic Neutropenia is primarily caused by mutations in the ELANE gene, which provides instructions for making the protein neutrophil elastase. These mutations lead to a periodic failure of the bone marrow to produce neutrophils, a type of white blood cell essential for fighting infection. Because it is a genetic condition, it is typically passed from parent to child in an autosomal dominant pattern, though it can also occur as a spontaneous (de novo) mutation.

Why is there confusion about contagion?

The misconception that Cyclic Neutropenia is contagious likely stems from the fact that individuals with the condition are highly susceptible to recurrent infections during their "neutropenic nadir"—the period when their white blood cell count is at its lowest. Because these patients may frequently experience fevers, mouth ulcers, and skin infections, observers might incorrectly assume they are suffering from a contagious illness. However, Cyclic Neutropenia is strictly an internal regulation issue of the immune system, not an infection being passed to others.

Is it safe to be around someone with Cyclic Neutropenia?

It is perfectly safe to live with, touch, or interact with someone who has Cyclic Neutropenia. There is no risk of transmission. In fact, it is the person with Cyclic Neutropenia who is at risk from the environment; they must take precautions to avoid exposure to common pathogens during their low-count cycles. Common triggers for symptomatic flare-ups include:

• Exposure to common viruses or bacteria that the body cannot fight off during low neutrophil counts.


• Physical or emotional stress, which can sometimes influence the severity of the cycle.


• Lack of preventative care, such as missing doses of Granulocyte Colony-Stimulating Factor (G-CSF) therapy.

Next steps

• Consult a hematologist-oncologist to manage neutrophil counts and infection prevention.


• Join the DiseaseMaps.org community to connect with other families navigating the daily realities of Cyclic Neutropenia.


• Maintain rigorous hygiene practices to protect the patient from external pathogens.
