Often, chronic and acute conditions may be confused. However, an acute disease may occur suddenly and last for a few days. It may affect any part of the body, but is treatable and curable with medications. Often, an acute disease affects only one part of your body and is not fatal. Generally, its symptoms are uniform throughout the entire duration.
On the other hand, chronic conditions last for several years. These conditions may persist throughout the lifespan. Over the years, these ailments may seriously damage your body. Chronic ailments may be prevented but are not completely treatable. The symptoms may vary over a period, as the body goes through relapse and remission phases.
