Why Diabetes is the odd one out
To understand this, we have to look at how diseases are classified based on how they spread.
Communicable Diseases: These are infectious diseases caused by pathogens like bacteria, viruses, fungi, or parasites. They can be transmitted from one person to another through air, water, food, or physical contact.
Tuberculosis (A): Caused by bacteria (Mycobacterium tuberculosis); spreads through the air.
Influenza (B): Caused by a virus; spreads via respiratory droplets.
Ringworm (D): A fungal infection; spreads through skin-to-skin contact or contaminated surfaces.
Non-Communicable Diseases (NCDs): These are chronic conditions that cannot be transmitted from person to person. They are generally caused by genetics, lifestyle factors (diet, lack of exercise), or environmental factors.
Diabetes (C): A metabolic disorder where the body cannot properly regulate blood glucose levels. You cannot "catch" diabetes from someone else.
he Role of Insulin in Diabetes.
In a healthy body, the pancreas produces insulin, a hormone that acts like a "key" to let blood sugar into your cells for energy. In Diabetes:
Type 1: The body does not make insulin.
Type 2: The body does not use insulin well or make enough of it.
