One in 100 children has autism – WHO.
The World Health Organisation has said that one in about 100 children has autism spectrum disorders, which constitute a diverse group of conditions related to the development of the brain.
The WHO said the estimate represents an average figure and reported prevalence varies substantially across studies.
It noted that some well-controlled studies have, however, reported substantially higher figures and the prevalence of autism in many low- and middle-income countries is unknown.
ASDs are characterised by some degree of difficulty with social interaction and communication. Other characteristics are atypical patterns of activities and behaviours, such as difficulty with the transition from one activity to another, a focus on details, and unusual reactions to sensations.
The abilities and needs of autistic people vary and can evolve over time.
