The remote medical platform is developed by  military-run telecommunications group Viettel while the Bluezone app will warn a user of the risk of COVID-19 infection if he/she is in close contact with another user who is a confirmed COVID-19 patient. 

When smartphones are installed with the Bluezone app, they are able to detect others within 2 metres and memorize themselves. If the app user is positive for the coronavirus (known as F0), through the saved data, health authorities can identify the F1 in close contact with the F0 and the system will alert the F1  about the risk of infection. They will be also provided with instructions to contact the competent health authorities for assistance.  

“Online public services including those in medical treatment are extremely important, particularly during social distancing. They help promote transparency, streamline administrative procedures, and reduce costs,” said Prime Minister Nguyen Xuan Phuc at the launch ceremony.
