Statistics by Country for Costello syndrome
Prevalance of Costello syndrome:
only about 250 cases of Costello syndrome has been reported worldwide, Genetics Home Reference website
About extrapolations of prevalence and incidence statistics for Costello syndrome:
WARNING! EXTRAPOLATED STATISTICS ONLY! Not based on data sources from individual countries.
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 Costello syndrome are typically based on US, UK, Canadian or Australian prevalence or incidence statistics,
which are then extrapolated using only the population of the other country.
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 Costello syndrome statistics below refer to.
The extrapolation does not use data sources or statistics about any country other than its population.
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 Costello syndrome in that region.
These statistics are presented only in the hope that they may be interesting to some people.
About prevalence and incidence statistics in general for Costello syndrome:
The word 'prevalence' of Costello syndrome usually means the estimated population
of people who are managing Costello syndrome at any given time (i.e. people with Costello syndrome).
The term 'incidence' of Costello syndrome means the annual diagnosis rate,
or the number of new cases of Costello syndrome diagnosed each year (i.e. getting Costello 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.
