Background This research highlights the importance of Internet of Things (IoT) technology in reducing the spread of the Omicron variant of COVID-19. In November 2021, the World Health Organization (WHO) reported the emergence of the SARS-CoV-2 Omicron variant (B.1.1.529) in South Africa. Despite ongoing preventive efforts, the pandemic continues to spread, and the rapid transmissibility of Omicron suggests that additional variants may emerge. Methods This research discusses several SARS-CoV-2 variations, examines the dynamics and structure of omicron transmission, and offers insights into global immunization campaigns. Furthermore, it addresses several IoT applications, such as temperature sensors in crowded areas for quick identification and isolation of sick individuals, digital telehealth remote doctor-patient interactions, guidance for IoT-assisted ambulances by remote medical experts, virus spread prediction, and health monitoring devices. The deployment of biosensors, artificial intelligence, and the Internet of Medical Things (IoMT) for COVID-19 and Zika virus detection was also reviewed. Wearable sensor integration in pandemic healthcare has been comprehensively assessed for IoT-based detection and protection approaches. IoT applications include hotspot detection, real-time health analysis, remote administration of medication, medical device tracking, and ambulance monitoring was also analysed. Results This article analyses consumer-orientated IoT gadgets such as smartwatches, smart glasses, drones, and autonomous swab test robots to support public health initiatives. It also emphasizes their function in identifying, monitoring, and responding to the Omicron cases. Conclusion The IoT plays a preventive role by improving real-time observation, supporting prompt action, and reducing face-to-face encounters, which helps contain the spread of Omicron. Moreover, IoT-based systems can track patients in home isolation, ensuring adherence to quarantine rules.
