Statistics by Country for Rett's syndrome
About these extrapolations of prevalence and incidence statistics for Rett's syndrome:
These statistics are calculated extrapolations of various prevalence or incidence rates
against the populations of a particular country or region.
The statistics used for prevalence/incidence of Rett's syndrome are typically based on US, UK, Canadian or Australian statistics.
This extrapolation calculation is automated and does not take into account any genetic, cultural, environmental, social, racial or other differences
across the various countries and regions for which the extrapolated Rett's syndrome statistics below refer to.
As such, these extrapolations may be highly inaccurate (especially for developing or third-world countries) and only give a general indication (or even a meaningless indication)
as to the actual prevalence or incidence of Rett's syndrome in that region.
About prevalence and incidence statistics in general for Rett's syndrome: The word 'prevalence' of Rett's syndrome usually means the estimated population of people who are managing Rett's syndrome at any given time (i.e. people with Rett's syndrome). The term 'incidence' of Rett's syndrome means the annual diagnosis rate, or the number of new cases of Rett's syndrome diagnosed each year (i.e. getting Rett's syndrome). 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.
Incidence (annual) of Rett's syndrome: 1 in 10,000-15,000 live female births
Incidence Rate for Rett's syndrome: approx 1 in 10,000 or 0.01% or 27,200 people in USA [about data]
