how common something is

How common something is in a place, group, or time.

استعمال کا انداز: the prevalence of [something] (in [group/place])
عام غلطی:
Learners sometimes confuse "prevalence" with "trend." "Prevalence" describes how common something is at a particular time, while a "trend" describes how something is changing over time. Spelling mistakes like *prevailance* are also common. Also, learners may say *many prevalences*; in normal use it is almost always uncountable, used in phrases like "a high prevalence of X" rather than "many prevalences."

rate of a disease in a population

In health and science, the share of people in a group who have a certain disease or condition at a given time.

استعمال کا انداز: [disease/condition] prevalence (in [group/place])
عام غلطی:
Learners often confuse "prevalence" with "incidence." "Prevalence" is how many people in a population have a condition at a certain time, while "incidence" is how many new cases appear over a period of time. Saying *the incidence is very high in the population at any given time* is usually incorrect if you mean prevalence.
ہم معنی الفاظ
disease rate (Informal equivalent; less precise than the technical term "prevalence.") | proportion (A general statistics term; in context it can refer to prevalence but is not specific to health or disease.)
متضاد الفاظ
absence (In epidemiological reporting, indicates that a disease or condition is not present at all in a population, the practical opposite of having measurable prevalence.) | eradication (Used when a disease has been completely removed from a population, effectively reducing its prevalence to zero.)
