The app, developed by Viet Nam’s leading cyber security firm BKAV, shall alert if one had close contact with people who have COVID-19, thereby minimizing the spread of the virus to the community.

When there is a new case of infection, one can learn whether he/she had close contact with this case or not simply by accessing Bluezone.

In a bid to assist the country’s fight against the COVID-19 pandemic, Viettel - a military-run industry and telecoms group, has increased the capacity of the Viet Nam Health Declaration app by 30%, said a Viettel representative.

From July 25 to August 2, this application usage reached 1.1 million declarations, nearly 28 times higher than the previous week. Particularly on July 30, the number of declarations reached 392,000, 12 times higher than the first day when the new community transmission case of COVID-19 was confirmed in Da Nang on July 25, according to Viettel.

The network operator has proactively upgraded the app storage capacity from 22 million to over 28 million declarations records.

As of 6pm on August 3, Viet Nam has a total of 642 cases of COVID-19, including 195 cases linked to the COVID-19 outbreak in Da Nang./.
