About prevalence and incidence statistics:
The term 'prevalence' of Osteogenesis imperfecta congenita, microcephaly, and cataracts usually refers to the estimated population
of people who are managing Osteogenesis imperfecta congenita, microcephaly, and cataracts at any given time.
The term 'incidence' of Osteogenesis imperfecta congenita, microcephaly, and cataracts refers to the annual diagnosis rate,
or the number of new cases of Osteogenesis imperfecta congenita, microcephaly, and cataracts 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.
