  1. Data is aggregated by week
  2. aNo data were identified on the number of individuals whose RT-PCR tests were repeated, nor were data identified regarding the number of contacts tracked for each positive test result, or the number of tests processed by each laboratory. For this reason, these indicators have no score assigned
  3. bThe data are relative to the specimens collected. No data is available for testing encounters per individual reported by the State of São Paulo
  4. cCovid-19 cases are the notified cases of the disease according to the database of the state health department
