IoT technology offers many benefits in health care and epidemic control and will greatly facilitate the process of continuous remote patient diagnosis and monitoring with wireless sensors and smart devices. This article aims to identify and analyze the applications of the Internet of Things to combat and control epidemics such as covid 19 disease. This research was applied in terms of purpose, which was conducted in two stages. First, by reviewing the theoretical foundations and previous studies through the method of reviewing texts, IoT applications in combating and controlling epidemic diseases such as covid 19 disease were identified; then, to confirm and prioritize the identified applications, these applications were provided to 23 experts from academic experts and experts in the medical field. IoT applications in the fight against and control of epidemic diseases such as covid 19, It has the dimensions of therapeutic applications (5 components and 9 indicators), Monitoring applications (4 components and 14 indicators), Information applications (2 components and 5 indicators), management applications (2 components and 8 indicators), prevention applications (7 components and 14 indicators). In the case of epidemics such as covid19 disease, The Internet of Things improves the quality of treatment and diagnosis, supports decision-making and monitoring patients 'vital signs, reduces hospital visits, and increases the ability to monitor and monitor patients' condition
