Sudan and South Sudan have multiple regional
sign languages, which are not
mutually intelligible. A survey of just three
states found 150 sign languages, though this number included instances of
home sign. Government figures estimate there are at least about 48,900 deaf people in Sudan.
By 2009, the
Sudanese National Union of the Deaf had worked out a Unified Sudanese Sign Language, but it had not yet been widely disseminated.
