Causes and consequences of infectious diseases:
Many diseases are caused by infection of the organism. A variety of organisms are moving around us. Bacteria of various diseases enter the body every day. However, if the germ of the disease enters the body, it is not that he will be infected. We have immune systems in place to prevent germs.
If this immune system is not strong enough in the body, the disease germs prevail. As a result, he/she became ill. On the other hand, if the body is strong and strong, the pathogens destroy the organism even when it enters its body. The germs are so small that they cannot be seen with an empty eye. Bacteria existed on the earth millions of years ago. However, not all organisms are harmful to the body. Some organisms are beneficial to the human body.
