Answer 2

Answer:

A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms.

Infectious diseases are caused by pathogens such as bacteria, viruses, fungi and parasites entering the body through the air we breathe, the food and drink we consume or through openings in the skin, such as cuts. As an example, through cough and sneezing a person can spread the cold virus to another.
