Which type of disease has a rapid and severe beginning?

A fulminating disease is characterized by a rapid onset and a severe progression. This type of disease often presents with sudden and intense symptoms, leading to significant health deterioration in a short time frame. Examples of fulminating diseases can include certain types of infections or conditions like fulminant hepatitis, which can lead to acute liver failure very quickly.

In contrast, an acute disease does involve a rapid onset but may not always be severe in its progression or consequence. Chronic diseases are long-lasting conditions that develop gradually and may worsen over time, while progressive diseases involve a steady deterioration in health over time rather than an immediate severe response. Understanding these distinctions is crucial in diagnosing and managing various medical conditions effectively.
