A collaborative effort of over 40 volunteers have been scraping official reports from the state Health Secretariats in order to obtain daily, city-level data about Covid-19 in Brazil. The data is then made available as bulk CSV downloads, as a JSON API as well as a web form on the Brasil.io open data platform. This is the only open data source available for daily Covid-19 data in Brazil that has municipality level granularity.

The Ministry of Health does not disclose data on Covid-19 in Brazil down to municipality level granularity. The State Health Secretariats do, but they're scattered all over the 26 states and federal districts and often only in PDF format, which is not great for reuse.

The impact this is already producing is increasing transparency on Covid-19 data in Brazil, making it easier for people to find out the state of the spread of pandemic in Brazilian territory, fostering more accurate news reporting and data analysis, academic or otherwise.

We still need to gather other important numbers, such as data on testing and recovered patients, which are starting to be reported by State Health Secretariats.
