Causes and Prevention of Diseases

A disease is a specific, identifiable, abnormal condition which negatively impacts the functioning or structure of a part or all of an organ, and this is not caused by any direct external injury to the organ. The word ‘disease’ comes from the Greek word “dos”, which meant body. Diseases are also often referred to as medical disorders which are associated with certain visible symptoms and signs. Most importantly, diseases are diseases.

The definition of a disease is: An ailment or abnormality that results in harm or death to an individual or to an animal. Although diseases are usually a result of a defective or malignant organism, they can also be caused by environmental, physiological or social factors. All organisms carry some amount of disease-risk gene, which makes them prone to disease. However, a healthy individual will usually be protected from infection by the immune system which normally gives rise to various types of diseases. However, people who are unhealthy are more prone to acquisition of diseases than healthy individuals.

Most countries in the world have categorized diseases into two main categories: infectious and non-infectious. An infectious disease is caused by an agent that is transmitted from one person to another. This agent can be a virus, bacteria, fungi, protozoa, etc. Non-infectious diseases are generally caused by external agents such as toxins, radiation, chemicals, and other hazardous agents. The world health organization (WHO) and the United Nations Organization for Health Statistics jointly class diseases into two main categories, these are: community-associated and communicable diseases.

Community-associated diseases refer to those diseases that can spread among a group of people because of common contact, like contact with infectious objects or through fluid transmission. Common examples of community-associated diseases include influenza and HIV/AIDS. On the other hand, communicable diseases are those diseases that can easily spread among a large number of people even without their knowledge or consent. The main categories of communicable diseases are; hepatitis B and C infections, common cold, diarrhea, cholera, measles, mumps, chicken pox, swine flu, tularemia, viral skin diseases, etc.

The main article continues with classification of diseases according to their modes of transmission. For example, a disease with a known mode of transmission may be neglected if there are no obvious signs or symptoms. This makes it difficult to contain the situation because the problem does not get solved. Diseases such as AIDS and cancer have been the cause of many deaths around the world; therefore, the prevention of these diseases should be given utmost priority, especially if the prevalence rate is very high among a certain group of people.

The classification of diseases also includes the manner of acquiring the disease. Some infectious diseases are sexually transmitted; others are acquired from objects contaminated with a person’s body fluids. Examples of sexually transmitted diseases are syphilis, genital warts, chlamydia and gonorrhea.
