The American newspaper “The Washington Post” published an article written by the correspondent in Brazil, Marina Lopes , dealing with the reality and creative actions carried out in Brazilian favelas to combat the coronavirus. The article explains several initiatives in the favelas of São Paulo and Rio de Janeiro, which act in the absence of a concrete government policy (municipal, state or federal) for these communities. The author highlights the importance of grassroots actions in these contexts and how the most vulnerable areas of the countries of the global north can learn from these experiences.
