To mark the six months of Covid-19 in Brazil, Fiocruz has published an assessment of the pandemic that has been having effects on the health of populations and challenging science all over the world. Made by a multidisciplinary team of researchers, the investigation includes the main aspects related to Covid-19, whether social, economic, structural, or epidemiological. The publication brings together analytic texts, data, and graphics that go deep in themes related to the social cost of the disease. A timeline highlights the most significant events up to now, and a final text lists Fiocruz actions in the response to the pandemic.
