Abstract – Novel coronavirus infection (COVID-19) has severely threatened public health. Frequent hospital visits are required for COVID-19 therapy and monitoring, which raises the load on hospitals and patients. Current advancements in wearable sensors and communication protocols are contributing to improving the healthcare system and will soon transform healthcare delivery. Future patient monitoring and health information delivery systems will be profoundly impacted by current and upcoming communication breakthroughs and microelectronics and embedded systems technology improvements. Bandwidth constraints, power consumption, and skin or tissue protection are significant obstacles. This study offers a comprehensive analysis of wireless body area networks, details their use in the COVID-19 treatment process, and proposes a paradigm for integrating body area networks into telemedicine systems. This study also addresses current developments, the WBAN-telemedicine system, and the scope of future research.
