Healthcare in all countries faces a lot of problems because of the outbreak of coronavirus (COVID-19). This includes weakness of capabilities and the lack of medical centers and hospitals. Also, the treatment of “pandemic diseases” chronic diseases needs daily reports about the patient health status, which enable doctors to recommend the suitable treatment. In this research, we propose an intelligent healthcare system that helps to improve healthcare organization using the techniques of IoT, allowing monitoring of patients at hospitals or remotely at their homes and sending a warning notification to the specialist. To decrease the required bandwidth, the time intervals between two successive readings is adaptive. The intervals increase as stable readings are noticed by the system.
