Answer:
Diabetes mellitus is not a contagious disease but a metabolic disorder, so there is no mode of transmission.
Step-by-step explanation:
Diabetes mellitus is a disease characterized by an elevated level of glucose in the blood, due to the lack of effect of the hormone insulin.
Insulin is a hormone produced by the pancreas, responsible for allowing the absorption of glucose by the body. The absence of this hormone leads to an increase in blood glucose levels. The two mechanisms responsible for diabetes are:
- Lack of insulin production in the pancreatic islets, which is seen in type 1 diabetes.
- Resistance of the organism to insulin, more related to type 2 diabetes.
Diabetes is a metabolic disorder, and a patient is unable to transmit it, since it is not a contagious disease.
