What are the Various Kinds of Disease?
Disease originally referred to a person who did not feel at ease or was uncomfortable and not well. When the word disease is mentioned, we mean a particular discomfort caused by a dysfunction of some part of the body.
Some diseases attack very suddenly (acute diseases). These can minor or serious, but they usually make the patient feel quite ill. The acute disease ends with a patient either recovering or dying from it.
If a disease continues for a long time, it is referred to chronic (chronic disease). If an organ in the body becomes damaged and can no longer function properly, this is known as an ailment or an organic disease.
Many of the common organic diseases are caused by parasites. These are small organisms that live within our body and take nourishment from our systems. Parasites can do serious damage to their hosts.
Some parasites are worms. They are big enough to be seen with the naked eye. Some of these worms travel through the body into the intestines and live on blood. This can easily weaken a person and cause death.
On the other hand, some parasites as so small that they are cannot be seen without a microscope. Germs are carried in many ways from person-to-person, most especially when somebody coughs or sneezes.
Sometimes they can get into our systems through food and/or drinking water. It is so easy for a sick person to transmit their disease to another person. These diseases are called communicable diseases or infectious diseases.
If the germs of a certain disease can be easily spread from person to person, it is referred to as a contagious disease. Germs come in many sizes and kinds.
Relatively small germ cells are called protozoa and the most common “protozoan disease” is malaria. The malarial parasite lives in red blood cells and destroys them.
Other germs can exist as very simple plant cells called fungi or molds. Athlete’s foot is an example of a fungus disease.
Bacteria are are living things that can be seen only through an ordinary microscope. Bacterial diseases include: tuberculosis, scarlet fever, tonsillitis and many other simple infections.
There are other types of germs too small that they need to be checked under an electron microscope. These are the viruses that are responsible for the most familiar sicknesses like measles, chickenpox, mumps and the flu.
There are other types of diseases that are not caused by germs. In fact, disease can be brought on by any physical or chemical injury. Too much sun can bring sunburn or sunstroke. Some chemicals that enter the body can be poisonous. Sometimes a harmless substance becomes poisonous to a particular person.
Allergies make a person sensitive to a substance in food, pollen, or even some medicine.
People in some lines of work sometimes run into particular risks of poison or other chemical damage because they may absorb dangerous chemicals into their bloodstream like lead poisoning, which is an occupational disease.
The body requires a certain amount of good food and clean water to live. If the food or water lacks certain substances that the body requires, the body can develop a deficiency disease like anemia.
In the absence of the necessary vitamins, diseases like crickets and scurvy develop.

History of the Statistical Classification of Diseases and Causes of Death
by: Ruth M. Loy
sales rank: 570494
This report describes the historic development of the disease nomenclatures and classifications that ultimately became the major international standard known as the World Health Organization’s (WHO) International Classification of Diseases (ICD). Written largely at the initiative of Dr. Iwao Moriyama, a participant in these developments for much of the 20th century, the report describes the historical, cultural, and scientific environment in which ICD evolved, expanded, and improved. Although the report focuses on the application of ICD to mortality, it also touches on nonmortality applications, particularly as these affected the classification for mortality.This report describes the historic development of the disease nomenclatures and classifications that ultimately became the major international standard known as the World Health Organization’s (WHO) International Classification of Diseases (ICD).
