Error frecuente:
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."

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.
