A disease is an abnormal condition affecting a living organism. Diseases are generally understood to be medical conditions that involve a pathological process associated with a specific set of symptoms. Localized diseases affect specific parts of the body; disseminated diseases spread to other parts of the body; and systemic diseases affect the entire body.
Acute diseases:-
A few diseases occur suddenly and last for a few days. These are known as acute diseases, such as common cold. This condition can be treated with medical treatment or on its own. Many times, acute diseases turn chronic if they continue to persist.
For eg, the first asthma attack is acute which later turns chronic. Strep throat, broken bone, appendicitis, influenza, pneumonia, etc.
Chronic diseases:-
The diseases that occur over a period of time and last longer, or even for the lifetime are called chronic diseases. Generally, if a disease lasts for more than three years it is called a chronic disease. Initially, the symptoms are very mild. A chronic disease progresses slowly and damages the body severely. It might sometimes be fatal.
For eg, Elephantiasis, Hepatitis C, HIV, arthritis, diabetes mellitus are some of the chronic diseases.
