Paget’s Disease of bone is not contagious, and there is absolutely no risk of transmitting it through physical contact, sharing spaces, or any other form of interaction. It is a chronic skeletal disorder characterized by the excessive breakdown and disorganized formation of bone tissue, rather than an infectious disease caused by a pathogen. What is the actual cause of Paget's Disease? The exact cause of Paget's Disease remains unknown, but current research points to a combination of genetic and environmental factors.

Paget’s Disease of bone is not contagious, and there is absolutely no risk of transmitting it through physical contact, sharing spaces, or any other form of interaction. It is a chronic skeletal disorder characterized by the excessive breakdown and disorganized formation of bone tissue, rather than an infectious disease caused by a pathogen.
The exact cause of Paget's Disease remains unknown, but current research points to a combination of genetic and environmental factors. Many patients have a family history of the condition, suggesting that specific genetic mutations—such as those in the SQSTM1 gene—may play a significant role. Rather than an infection, Paget's Disease is considered a localized metabolic bone disorder where the body’s normal bone remodeling process becomes overactive and chaotic.
Some historical theories once speculated that a slow-acting viral infection might trigger Paget's Disease, which led to widespread misunderstandings. However, modern clinical evidence has largely moved away from the idea that a transmissible virus is the primary cause. Because Paget's Disease can affect multiple family members, people sometimes mistakenly assume it spreads like an illness, when in reality, it is simply being passed down through genetic inheritance patterns.
While the condition is not infectious, researchers are investigating potential environmental triggers that might interact with genetic susceptibility. Factors being studied include:
