Hint: A disease is an abnormal condition that unfavorably affects the structure or function of all or part of an organism, and that is generally not due to any sudden external injury. A disease may be caused by external factors such as 1. Pathogens or 2. Internal dysfunctions.
Complete step by step answer: The term disease broadly refers to any condition that impairs the normal functioning of the body. The term is used to refer specifically to infectious diseases, which are clinically evident diseases that result from the presence of pathogenic microbial agents, including 1.Viruses 2.Bacteria 3.Fungi 4.Protozoa 5.Multicellular organisms 6.Some aberrant proteins commonly known as prions. Diseases can be of two types: 1.Acute diseases 2.Chronic diseases Acute diseases: Acute disease normally develops instantaneously and lasts a short period of time,mainly a few days or weeks. Acute conditions are normally caused by a virus or an infection, or by the misuse of drugs or medications. Acute condition includes: 1.Asthma attack 2.Broken bone 3.Bronchitis 4.Burn 5.Common cold 6.Flu 7.Heart attack 8.Pneumonia 9.Respiratory infection 10.Strep throat Chronic conditions develop slowly and may worsen over an extended period of time—months to years. Chronic conditions are often caused by unhealthy behaviors that increase the risk of disease 1.Poor nutrition 2.Inadequate physical activity 3.Overuse of alcohol 4.Smoking 5.Social 6.Emotional 7.EnvironmentaL 8.Genetic factors Chronic conditions are slower to develop, may progress over time, and may have any number of warning signs or no signs at all. Chronic condition includes: Alzheimer’s disease Arthritis Chronic obstructive pulmonary disease (COPD) Depression Diabetes Heart disease High blood pressure High cholesterol Obesity Osteoporosis Stroke So, Chronic diseases are more harmful than acute diseases.
Note: Acute conditions are severe and sudden in onset. This could describe anything from a broken bone to an asthma attack. A chronic condition, by contrast, is a long-developing syndrome, such as osteoporosis or asthma. Note that osteoporosis, a chronic condition, may cause a broken bone, an acute condition. An acute asthma attack occurs in the midst of the chronic disease of asthma. Acute conditions, such as a first asthma attack, may lead to a chronic syndrome if untreated.
