Diseases and Hygiene

What Is A Disease?

A disease is a particular abnormal condition that negatively affects part or all of an organism. Diseases are caused by two different things: An external pathogen, which means that a virus is passed to you from another source, or, it could be caused by an internal disfunction. An example of an internal disfuntion: An internal disfuntion of your immune system could cause many varying diseases, such as allergies or hypersensitivity.
An example of an external pathogen is if you are in close proximity to someone who is sick, if they touch you, the disease in them could get passed onto you.

Types of Diseases

There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases, and physiological diseases. Of course, there are other types, but these are the most common.

• Infectious Diseases: infectious diseases, simply, are just contagious iseases, and infection, such as the common cold, that commonly spreads from one person to another, but does not necessarily spread through everyday contact.
  


• Deficiency Diseases: The definition of deficiency is: to lack something. So deficiency diseases are caused by a lack of something important in your diet, typically a mineral or vitamin.
  


• Hereditary Diseases: A hereditary Disease is a disease/infection that is passed on through genetics, by family/relatives.
  


• Physiological Diseases: A physiological disease is an illness that interferes with the way that the functions of the boy are carried out.
  

Causes of Diseases

If a person who is sick touches you, or sneezes or coughs next to you, what's your first response? You're probably worried that you will get sick now, right? Well, believe it or not, not all diseases are infectious by touch. The diseases that spread from hand-to-hand contact contain what is known as pathogens, which carry varieties of bacteria, viruses, and fungi.

Some diseases, like cancer and heart diseases, are non-infectious. These diseases are either partially or completely based on genetics.

Fun Fact!

When people do not know the cause of a disease, people used to mythologize the diseases, or use it as a symbol for something that the place thinks is evil!
