Final answer:
Acute disorders are characterized by a rapid onset of symptoms that resolve quickly, usually within a few days to weeks, as opposed to chronic diseases that last much longer.
Step-by-step explanation:
Acute disorders are conditions with rapid onset and short duration. Unlike chronic diseases that persist for months to years, an acute disease usually resolves within a few days or weeks. Infectious diseases like influenza are common examples of acute diseases, with symptoms appearing quickly and resolving after a short period. Noninfectious diseases can also be acute, sometimes resulting in rapid death due to severe conditions, such as certain types of cancer or heart disease. Understanding the difference between acute and chronic diseases is crucial for proper diagnosis and treatment.
For instance, an acute febrile illness is characterized by a sudden fever and symptoms that resemble those of the flu. These symptoms peak quickly and then typically resolve. It's important to note that stress can exacerbate both acute and chronic conditions by constantly activating the body's emergency response systems.
