Distinguish between infectious and non-infectious diseases. Discuss briefly how the infectious diseases travel from one person to another.

Infectious and non-infectious diseases are two broad categories of diseases that affect the human body. The key difference between these two types of diseases is the way they are caused and spread.

Infectious diseases are caused by microorganisms such as bacteria, viruses, fungi, and parasites. These microorganisms can enter the body through various routes, such as through the mouth, nose, skin, or other openings in the body. Once inside, they can multiply and cause damage to the body's tissues and organs, leading to various symptoms of the disease. Infectious diseases can spread from person to person through direct contact, such as touching or kissing, or through indirect contact, such as touching contaminated surfaces or breathing in droplets containing the infectious agent.

Examples of infectious diseases include the common cold, influenza, tuberculosis, measles, malaria, _________ _________ ____ _______ ____ _________ _____ ___ _________ ______ ___ ________.
