A wearable device that can take a patient's vitals and send it to a healthcare worker’s mobile application wirelessly. The value is in the data which can now be used in realtime as a risk assessment tool for the healthcare worker utilizing location and other valuable factors to prevent illness, disease and misdiagnosis. This data can be used to map disease spread rapidly for Governments and NGOs on a dashboard providing value to the patient, healthcare worker, clinic, and NGO/Government. The device is worn on the finger of the patient, and the mobile healthcare worker presses a button that sends all the information in to the phone. This is all done without internet connection, and sent to the cell phone.
