THE Coronavirus-SUS, official application of the Federal Government of Brazil, available for smartphones with Android and iPhone (iOS), you can warn if you have been in contact with people diagnosed with COVID-19. To offer this information, the app has the technology “Exposure Notification API”Or Exhibition Notification System, jointly developed by Google and Apple, for their mobile systems.
In Brazil, only the Ministry of Health is licensed to use the resource. The function present in the app alerts, within 24 hours, if people who tested positive for the disease were close to you, in the last 14 days, based only on your location.
According to the government sector responsible for health, the use of the technique of tracking positive cases of the disease is a factor that can help in the transition of the population back to everyday life. In addition, the measure represents a strategy for managing the risk of new outbreaks of the disease.
How to register my COVID-19 positive test
On the main screen of the application, there is the option to “share your positive test” for COVID-19. It is worth mentioning that the identity of the infected individual is not disclosed to other users of Coronavirus-SUS.
Before the information is included in the app, it is necessary to validate the result of your exam (PCR or serological) on the Valida Coronavirus SUS website [validacovid.saude.gov.br].
The compatibility between the examination presented and integrated data from the National Health Data Network (RNDS) and the surveillance platform (e-SUS Notifica) will be checked – both gather records of patients with COVID-19 in the country.
Upon confirmation, a six-number code (token) is generated. This numerical sequence is essential for your exam to appear in the application.
How does the Coronavirus-SUS application work?
According to the Ministry of Health, the Exposure Notification System does not collect personal information – such as the user’s name, social security number and mobile phone number – or geolocation data. Therefore, as the app does not track the person tested as positive for COVID-19, nor the person who receives notification of possible exposure to the disease, the security of the identities of those using the platform is assumed.
Bluetooth always on
A randomly generated code is assigned to each device and, for privacy purposes, that code changes every 15 minutes. When smartphones with the downloaded app they get physically closer, the codes are “exchanged” via Bluetooth Low Energy and the information is stored in your device’s cache.
A diagnostic key (which does not contain personal data) is created when a user has their positive test for the disease validated and listed in the app. Coronavirus-SUS regularly analyzes the codes on the server, comparing them with the keys saved on your device. With this, it is possible to indicate whether you have been exposed to the risk of infection.
With the encrypted sending of data, via low-energy bluetooth, the application identifies contacts at a distance of 1.5 to 2 meters and for a minimum time of five minutes, between devices that have the Coronavirus-SUS installed. In addition, the exposure notification tool must be enabled.
For the app to be in full operation, it is necessary, then:
- Exposure notification tool enabled;
- Bluetooth on your device always on;
Finally, if the user contacts a person infected with sars-CoV-2, a notification will be sent by the Ministry of Health. In the message, it will be informed that this is a preventive measure. Therefore, personal hygiene must be strengthened and attention should be paid to the possible appearance of symptoms characteristic of the disease – such as sore throat, fever, cough and shortness of breath.
By tapping the “Possible exposure” option on the main screen of the app, you can check a “history” of the likely risk of contagion alerts, in the last 14 days.
Reliable information and fighting Fake News
The application also brings together articles with tips – what you need to know and do to eliminate the virus effectively – and news from official portals. You can check instructions on how to prevent and how to prevent the transmission of the disease-causing agent, for example. This is a way to fight false news and deliver correct information to the population.
It is worth mentioning that communication with users is done exclusively by the app. That is, one should be wary of e-mails, SMS and any other type of interaction, especially if personal information is requested.
