According to the latest data from the Authority of Information Technology Application of the Ministry of Information & Communications, by July 12 there had been a total of 40.21 million downloads of the Bluezone application. It records contact history, thereby providing early warnings and helping accurately trace people suspected of being infected with Covid-19.
The effectiveness of Bluezone has been proven as this app helps health authorities trace thousands of cases having close contact with infected people or those who are suspected of infection.
In the two largest cities in the country, Hanoi and Ho Chi Minh City, the percentage of people using Bluezone is over 30%, with 36.9% for Hanoi and 35.3% for HCM City.
These are relative numbers because there are people who download and install Bluezone but do not regularly turn on the app and those who downloaded it but then deleted and re-downloaded Bluezone. Thus, it is still a long way for Vietnam to reach the ideal number of Bluezone users for this app to fully take effect.
According to experts, the Bluezone app will only maximize its effectiveness if 60% of the adult population use it. Therefore, forcing people to install and use the app is an extremely necessary measure to effectively trace and prevent the spread of the disease.
In addition to identifying and finding people suspected of being infected with Covid-19, Bluezone is now upgraded with many new features such as electronic medical declaration and QR code scanning. These are all important technological solutions to control the disease.
Instead of being used only as an auxiliary solution to find the source of the disease, local authorities should change their minds and turn Bluezone into the main solution to trace people suspected of being infected with Covid-19 by ordering all people to install and turn on the app.
