Acute diseases are those that last for shorter periods of time, typically ranging from a few days to a few weeks. These diseases often have a rapid onset and tend to resolve relatively quickly, either through treatment or the body's natural immune response. Examples of acute diseases include the common cold, influenza, and acute gastroenteritis. In contrast, chronic diseases persist over a longer duration, often lasting for months or years.
