What is the term for a sudden increase in the severity of a disease?

The term that refers to a sudden increase in the severity of a disease is “exacerbation.” This term is commonly used in medical contexts to describe a situation where symptoms of a disease become more intense or problematic for the patient. Exacerbations can occur in various conditions, such as asthma or chronic obstructive pulmonary disease (COPD), where a patient may experience a flare-up or worsening of symptoms, necessitating changes in treatment or care.

Understanding exacerbation is crucial for healthcare providers because it helps them to monitor and manage their patients more effectively. Recognizing the factors that can lead to exacerbations allows for preventive care measures and timely interventions, significantly impacting patient outcomes.
