Is Diabetes a Communicable Disease?

5 min read 2026-03-13

You might have heard people ask whether diabetes can ‘spread’ from one person to another, especially given how common it has become worldwide.

According to the ICMR-INDIAB study, diabetes has risen from 32 million in 2000 to 101 million in 2025.1 This rapid rise and questions like ‘is diabetes a communicable disease emphasise the need to educate people on diabetes.

Let’s understand what diabetes is and isn’t in the context of public health.

Can Diabetes Spread Between Individuals?

No. Diabetes is a non-communicable disease. It does not spread between individuals through touch, air, blood, or any form of physical contact. Diabetes is fundamentally different from communicable diseases like the common cold, COVID, and tuberculosis. You cannot “catch” diabetes from someone who has it, even through close or prolonged contact.

What is Diabetes?

Diabetes is a disease of poor control of blood glucose levels. The most prevalent form, type 2 diabetes, occurs when the body does not produce enough insulin or cannot use it effectively. It accounts for 96% of diabetes and is an important non-communicable disease which has serious threat to human health.

Similarly, Type 1 diabetes involves autoimmune destruction of pancreatic beta cells, resulting in little to no insulin production.

The non-modifiable risk factors of diabetes include:
● Genetics
● Age
● Ethnicity
● PCOS
● Gestational Diabetes

The modifiable risk factors of diabetes include:
● Unhealthy Diet
● Obesity
● Sedentary lifestyle
● Smoking
● Sleep Disturbances

Communicable vs Non‑Communicable: The Scientific Consensus

This table is to explain the core differences between a communicable and non-communicable disease:

In essence, communicable diseases are spread through infections and viruses, while non-communicable ones are not caused by any infection. With this logic, you gain the answer to the question, “Is diabetes a communicable disease?”

Diabetes is Not A Transmissible Disease

In summary, diabetes is a non-communicable disease and does not spread from person to person. It develops due to metabolic dysfunction shaped by genetics, lifestyle, and environmental factors, making prevention and evidence-based care far more important than concerns about transmission.
