What characteristics define an emergent disease?Multiple choice question.Most often it affects the youngest members of the population.It has not been previously known or has been absent for at least 20 years.As a new disease it is usually not widespread.
Solution
An emergent disease is typically defined by the following characteristics:
-
It is a disease that has not been previously known or has been absent for at least 20 years. This means that it is a new disease to the population, or one that has re-emerged after a significant period of absence.
-
While it can affect any demographic, there is no rule stating that it most often affects the youngest members of the population. Emergent diseases can affect any age group, and the susceptibility often depends on the specific disease and the individual's immune system.
-
As a new or re-emerging disease, it is usually not widespread initially. This is because it takes time for the disease to spread among the population. However, with factors like globalization and increased travel, an emergent disease has the potential to become widespread more quickly than in the past.
So, based on these characteristics, the correct answer to the multiple-choice question would be: "It has not been previously known or has been absent for at least 20 years."
