What defines a Disease?<\/strong><\/h1>\n

There are four main types of diseases:<\/strong> infectious diseases, deficiency diseases, hereditary diseases, and physiological diseases.<\/p>\n

The disease may be acute, chronic, malignant, or benign. Of these terms, chronic and acute have to do with the duration of disease, malignant and benign with its potentiality for causing death.<\/p>\n

An acute disease process usually begins abruptly and is over soon. It usually requires immediate surgical treatment. The term chronic refers to a process that often begins very gradually and then persists over a long period.<\/p>\n

The terms benign and malignant, most often used to describe tumors, can be used in a more general sense. Benign diseases are generally uncomplicated and a good outcome is usual. Malignancy implies a course that, if left untreated, will result in fatal illness or death. Cancer is the general term for malignant tumors.<\/p>\n

Origins of Human Disease<\/strong><\/h2>\n

We\u2019re still trying to eradicate diseases that have plagued humans for centuries.<\/p>\n

Malaria, for example, has been traced back to 2700 BC in China. Many believe that South Africa, the cradle of humankind,<\/a> <\/em>is the root of human disease pathogens.<\/p>\n

However, we still have enormous gaps in knowledge when it comes to disease and human evolution. South Africa is a very rich biogeographic disease region and it\u2019s likely that we can find the key to the original state of human disease in prehistoric populations who inhabited the region.<\/p>\n

Coronary artery disease<\/strong><\/h2>\n

The world\u2019s deadliest disease is coronary artery disease (CAD). CAD occurs when the blood vessels that supply blood to the heart become too narrowed and create issues in the body. If left untreated, it can lead to heart failure and arrhythmias.<\/p>\n

Although it\u2019s still the leading cause of death, mortality rates have declined in many countries. This may be due to better public health education, and more general access to healthcare. However, in many developing nations, mortality rates of CAD are significantly on the rise.<\/p>\n
