 COVID-19 has affected Brazil in many ways, but the impact is bigger among vulnerable people. Zika helped us a lot in the past and now again because we structure a research network of social scientists. And also in few crews, we coordinated a very complex response during Zika outbreak. And now we are using that experience to support us, to help us. But COVID-19 is completely different. Favelas are areas of exclusion. Vitamins of a kind of social and economic and political process of vulnerableization. So without sanitation, without clean water, living in many people in the same room, in the same bed. Many of them without bathroom and access to water. In the critical moment of the COVID-19, the impact is immense. There are many initiatives to try to respond to it. One of them is COVID in Favelas. We are gathering scientists, social scientists, health authorities to find and to dialogue to fit strategies to respond in an adequate way to these kind of territories. To guarantee the human rights, to improve equity and to avoid misinformation and stigmatization. Our intention here is to protect the lives. We can build a new world, a better world. The whole world needs very strong and universal health systems as a right, not as a commodity.
