Situation - Hepatitis C has been growing in the Brazilian population and worldwide. This happens due to the lack of testing and treatment, even though they are free in Brazil. Hepatitis C is a silent disease that, if not treated in time, can lead to liver cirrhosis and liver cancer.

Brief - Establish a controlled area of action to test and treat hepatitis C in its entire population. The repercussion and notoriety of the action will give strength to the eradication of hepatitis C through other similar projects.

Objectives - Remove this area entirely from the hepatitis C map, zeroing its existence, testing and treating all its inhabitants, in order to create a system capable of being reproduced in other areas of Brazil.

We erase Ihabela / SP - Brazil - from the World Map of hepatitis C in realtime. With each computed test, a piece of the island's image disappeared on the action's landing page. As 100% of the population is under test, the island has disappeared completely.

Data gathering - The nurse who applies the test and treatment, touches the logged-in landing page area, computing Data.

Data interpretation - In realtime, the system identifies that a test has been done, transferring the information to the screen that shows the area decreasing towards 0%.

Targeting - All inhabitants of Ilhabela / SP- Brazil.

Implementation - A communication was made in Ilhabela about the action. The first phase invited the population to go to the health posts in the city. The city's nurses and health posts were divided into 5 regions. The inhabitants who did not attend health posts after the call was visited in their homes by the project teams.
