About prevalence and incidence statistics:
The term 'prevalence' of Jejunal Atresia usually refers to the estimated population
of people who are managing Jejunal Atresia at any given time.
The term 'incidence' of Jejunal Atresia refers to the annual diagnosis rate,
or the number of new cases of Jejunal Atresia diagnosed each year.
Hence, these two statistics types can differ:
a short-lived 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.
