The term "eHealth" refers to the use of digital data -transmitted, stored and retrieved electronically- in support of health care, both at local sites and at a distance. Several years ago, the World Health Organization proposed to develop programs for eHealth, including tele-consultations, tele-referrals, forward-storage concepts (e.g., tele-radiology and tele-prescriptions) and electronic patient records, to improve early diagnosis of thyroid diseases and follow-up of patients who have developed thyroid cancer after exposure to radioactive fallout following the accident at the Chernobyl Nuclear Power Plant, the World Health Organization and the Sasakawa Memorial Health Foundation, in cooperation with the Ministry of Health in the Republic of Belarus, have established and promoted a project entitled "Medical Relief for Children Affected by the Chernobyl Accident through the Development and Implementation of Health Telematics," to achieve these goals. In this communication, I review the current state of eHealth and the development of the health telematics project in Belarus.
