The word 'prevalence' of Gastroesophageal Reflux Disease usually means the estimated population
of people who are managing Gastroesophageal Reflux Disease at any given time (i.e. people with Gastroesophageal Reflux Disease).
The term 'incidence' of Gastroesophageal Reflux Disease means the annual diagnosis rate,
or the number of new cases of Gastroesophageal Reflux Disease diagnosed each year (i.e. getting Gastroesophageal Reflux Disease).
Hence, these two statistics types can differ:
a short disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
