### Key Components of eHealth 1. Telemedicine:

1. Remote delivery of clinical services using technology (e.g., virtual consultations, remote diagnostics).

2. Mobile Health (mHealth):

1. Use of mobile devices to deliver health information, monitor patient conditions, and promote healthier behaviors.

3. Electronic Health Records (EHR):

1. Digital systems for storing patient medical history, accessible to authorized healthcare providers.

4. Health Information Systems:

1. Integrated systems for managing hospital operations, public health databases, and resource allocation.

5. Wearables and IoT in Healthcare:

1. Devices like fitness trackers, smartwatches, and IoT-enabled medical devices that monitor vital signs and other health metrics.

6. eLearning and Training for Health Professionals:

1. Online platforms for continuing medical education and skill development.

7. Artificial Intelligence (AI) in Healthcare:

1. AI-driven tools for diagnostics, treatment recommendations, and administrative optimization.
