The results of this study may help to better understand the cause of expressive language deficits observed in some children with HIV infection. More specifically, it will determine if any speech and feeding problems of HIV-infected children are associated with oral thrush. Learning more about the impact of oral thrush on the speech, feeding, and the self-concept of children with HIV disease may be used for parent and patient education and to develop rehabilitative recommendations to benefit HIV-infected patients with oral thrush.
