Clouio automates disease tracking at hospitals in order to make disease tracking faster and more precise. By using BLE and WIFI technology we track disease by tracking patients. By giving patients at hospitals a trackable wristband when entering the hospitals and using tracking gateways we can track patients. When a patient then gets sick the doctors can search for the patient in our system. The system then provides the doctor with an list of which people the sick patient has met during their visit and where they have met, thus seeing the patients that are in risk of getting sick from covid-19 (or other communicable diseases) at the hospital. This solution can also help track diseases at retirement homes in the same way and can incorporate tracking tools and materials as well.
