Various Diseases Causing Germs

Disease actually referred to what it says dis-ease. People who did not feel at ease or were uncomfortable and not well was said to be at dis-ease. Nowadays of course when people talk about disease, we mean a particular discomfort caused some germs or by a dysfunction of some part of the body.

Some diseases causing germs attack very suddenly. These diseases are called the acute diseases. These can be serious or not, but they usually make the patient feel quite sick. The acute disease caused by various germs ends with a patient either dying of the disease or recovering from it. Sometimes, the disease can continue for a long time, which is called a chronic disease. If an organ of the body is so damaged by the germ attack that it can no longer work well, physician call this ailment an organic disease.

Most of the organic diseases are caused by germs which are small organisms that live within us and take nourishment from our systems. Germs do damage to their hosts and are responsible for parasitic diseases. Some germs, like worms, are big enough to be seen with the naked eye. In some parts of the world, people can easily get attacked by hookworms when they walk barefoot and then these worms travel into the intestines and live on blood. This disease can easily weaken a person and some of them can even die.

On the other hand, some germs as so small that they are cannot be seen without a microscope. Such germs are called microorganisms. They cost the acute germ diseases. Germs are carried in many ways from person-to-person, most especially when somebody sneezes or coughs. Sometimes they can get into the systems through drinking water and food. It is thus very easy for a sick person to communicate their disease to a healthy one. For this reason, such diseases are called infectious diseases or communicable diseases.

If the germs of a certain disease are spread easily from person to person, it is called a contagious disease. Germs come in many kinds and sizes. Relatively small germ cells are called protozoa and the most well known protozoan disease is malaria. The malarial parasite lives in the red blood cells and destroys them. Many people in the tropical parts the world suffers from malaria every year, which probably kills more people than any other diseases.

Other germs are very simple plant cells called molds or fungi. Athlete's foot is a good example of a fungus disease. Bacteria are even simpler than the germs. They are living things which can be seen only through an ordinary microscope. Bacterial diseases include scarlet fever, tuberculosis, tonsillitis and many other simple infections.

Finally, there are other germs too small to be seen under an ordinary microscope that they need to be observed under an electron microscope. These are the viruses that are responsible for the most familiar sicknesses like chickenpox, measles, mumps and the flu. These are widely called viral diseases. 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 other than germs.
