Once in the network, an individual always knows how he relates to infected people (which F he is) based on the relationships he has with individuals, places, or journeys that are already archived in the network. Therefore, the more individuals involved in providing exact data, the more accurate the calculation results of COVID-19 Check are.

How COVID-19 Check can help you and other anti-epidemic actions

COVID-19 Check is designed to assist in providing information for different parties when the whole country participates in reversing Coronavirus:

• For users: If everyone regularly updates their interpersonal contacts, places and journeys within the past 14 days, they will always know their risk of infection at any level from F0 to F5 +. Therefore, if the information is updated daily, users are the first side to benefit from that database to prepare for different situations.
• For government’s anti-epidemic departments: This network will help the government to localize, predict and prepare for quarantine or treatment of potentially infected individuals as well as disinfection of unsafe areas to prevent the rapid spread of the virus to the community.
• For researchers: The COVID-19 Check’s network will provide information that can be applied in analysis and the use of AI algorithms to assist in other anti-epidemic activities.

How to use COVID-19 Check

As for users, COVID-19 Check works in a very simple way:

1. Users create accounts by inputting their mobile phone number into the system. Mobile phone number is the only identification that users provide to authenticate and avoid spam.

2. Users use the feature “Check-In” to enter data in the past 14 days, including:

• close contact with others
• journeys using public transport
• locations they have been present.

The first turn users inputting data may take time as the system requires data in the past 14 days; however, afterwards, users can easily update their data every day when an event happens.

3. Users check their risk of infection (which F they are). The system also automatically notify users if there is any change in their risk to help them prepare necessary plans.

How is the data privacy guaranteed by COVID-19 Check?

COVID-19 Check takes great care to protect users’ privacy as well as personal data and is designed based on the following principles:

• The system only requires a mobile phone number or an email to authenticate the user. If users use multiple mobile phone numbers, they can add these numbers to let the system know and manage contacts more accurately. Also, the system does not require users to provide any additional personal information, including Name and Address.
• Contacts are also created via mobile phone numbers or email identifiers.
• Contacts that last more than 14 days compared to the current day are automatically deleted from the system permanently.

Our next development plan and what can you do to join hands with COVID-19 Check?

COVID-19 Check is designed to handle huge amounts of data with hundreds of millions of nodes (equivalent to Vietnam’s population) and billions of relationships. The system is also built with an open plan so that it can be easily integrated with other data sources such as the huge social data of Kompa / Filum or data sources from other anti-epidemic parties. Thus, the network can maximize its usefulness for both users and organizations participating in the process of preventing Coronavirus.

In the first phase, Got It engineers already developed the backend and web frontend part, then tested it with very good results. However, the web frontend still has many limitations for users, especially in data entry because most of them must be entered manually.

In the upcoming time, the team will continue developing the mobile application to make the “Check-In” step become automated and create more utilities for users, thereby reducing the laziness of updating data due to too much manual work.

If you would like to join Got It to help reverse the Coronavirus pandemic, don’t hesitate to contact our team via email: covid19@got-it.ai. Got It will publish the Trello board soon to let everyone know the roadmap of this entire project.
