Which of the following is not a communicable disease?

Communicable Diseases: These diseases are caused by microorganisms (such as viruses, bacteria, fungi, or protozoa). Their main characteristic is that they can spread from an infected person to a healthy person through contaminated water, food, air, or vectors (like mosquitoes).

Non-Communicable Diseases (NCDs): These diseases do not spread from one person to another. They are also known as chronic diseases as they often last for a long time in the body. They are caused by biological conditions and external factors rather than infection.
