21/September – COVID-19 Time varying reproduction numbers estimation for Brazil

These plots show the estimation of the instantaneous reproduction number for all the states in Brazil. These reports uses the method described in the work A New Framework and Software to Estimate Time-Varying Reproduction Numbers During Epidemics. We used the serial interval parameters similar to the ones used by CMMID with a \(\mu = 4.7 (3.7 - 6.0)\) and \(\sigma = 2.9 (1.9 - 4.9)\).

Note

This plot uses official data from government, reports until 21/September. This method is sensitive to changes in COVID-19 testing procedures and the level of effort used to detect cases. Therefore, changes in the testing efforts will introduce bias if the testing practices are not kept consistent. So please keep in mind these limitations, that are often not stated in many analysis around there. Imported cases weren’t also considered in this analysis, neither the delay of the symptoms onset and reporting.

Warning

Remember that this is the instantaneous reproduction number, therefore when it is below 1.0 for one or two days, it doesn’t mean everything is ok. This method is less sensitive to under-reporting but as long as the bias is constant. So please, read the plots with the limitations in mind. As an example, Portugal had an R(t) below 1.0 for almost 3 weeks before relaxing interventions, so keep in mind that it is not about being below 1.0 for a single day but for weeks.
