Telehealth is a revolutionary healthcare approach that utilizes telecommunications technology to provide medical services remotely. It includes virtual consultations, remote monitoring, and the exchange of medical information through secure platforms. Telehealth improves access to healthcare, especially in remote areas, enhances patient convenience, and reduces costs for both patients and healthcare systems. However, challenges include the digital divide, regulatory complexities, and privacy concerns. The future of telehealth holds promise with AI integration, expanded specialties, and potential global reach, making it a transformative force in modern healthcare.
