The system combines the telehealth applications with the services from local psychosocial intervention teams. In this case report, we will present an 11-year old child with autism spectrum disorder who returned from the United Kingdom to Turkey and were held in a dormitory for a 14-day quarantine and managed with a telehealth based system developed by our institution to specifically support children with special needs during COVID 19 pandemic. Considering the nature of the disorder in individuals with autism, due to the negative effects of environment and routine change, the intervention to be made to these individuals must be early and ready. Since the first day of our case, with the intensive application of both behavioral and medical treatment with a multidisciplinary team, a significant change was seen in our patient's symptoms, therefore, it supports the idea that rapid intervention and a ready system are crucial.
