Acute: "Having a sudden onset, sharp rise, and short course"
Idiopathic: Of unknown cause. Any disease that is of uncertain or unknown origin may be termed idiopathic.
Exacerbation: A worsening. In medicine, exacerbation may refer to an increase in the severity of a disease or its signs and symptoms.
Epidemiologists are scientists who study diseases within populations of people. In essence, these public health professionals analyze what causes disease outbreaks in order to treat existing diseases and prevent future outbreaks.
The word idiopathic comes from the ancient Greek ιδιοσ (idios, one's own, proper, particular) and πάθος (páthos, suffering, i.e. disease). Therefore, idiopathic literally means something like “a disease of its own”.
An idiopathic disease is a “disease of itself,” that is, one of uncertain origin, apparently arising spontaneously. Idiopathic pulmonary fibrosis (IPF) is a disease of aging that has long had a mysterious etiology and pathogenesis, but findings in the telomere biology field have begun to provide clues.
Sudden onset symptoms are symptoms that develop quickly. They can also be called quick onset symptoms or acute symptoms. Sudden onset symptoms can change over time, worsen rapidly, and be severe. They are different from symptoms that develop slowly over a period of time, which are called chronic symptoms.
The disease onset is the first time that there has been noted to be a “change” in one's usual health status with the identified signs and/or symptoms being able to be directly attributable to a specific disease process.
Onset of symptoms Gradual onset: over 3 - 4. days. Rapid onset: within 3 - 4 hours. Sudden onset or worsening of severe symptoms, but can. develop over days.
A disease vector is any living organism that transmits an infectious disease to humans (or in agriculture to animals and plants).
Infectious disease epidemiology is the study of how and why infectious diseases emerge and spread among different populations, and what strategies can prevent or contain the spread of disease at the population level.
Epidemiology is the branch of medical science that investigates all the factors that determine the presence or absence of diseases and disorders.
