The moving average of deaths by Covid-19 in the Federal District in the last seven days has grown to 15.3. The high comes on the next day of the indicator registering the lowest number since Monday, June 16.
In comparison with the moving average calculated two weeks ago, there was a fall of 40.2%. This means that deaths are decreasing, since variations in the number of deaths are greater than 15%.
The calculations are from (M) Data, nucleus of data journalism of the Metropolises. They take into account the numbers released daily by the Ministry of Health that feed the interactive panel with information about the pandemic. They are compiled since the first case notified in Brazil.
In absolute numbers, the DF has already confirmed 192,200 cases of the disease and 3,255 deaths. In the last 24 hours there were 928 new infections and 31 deaths.
Tracking the progress of the Covid-19 pandemic based on absolute death or case data is far from ideal. That’s because they can have very large daily variations, especially delays in records. On weekends, for example, it is common to notice a significant reduction in numbers.
To reduce this effect and produce a more accurate view, the moving average is widely used around the world. The rate represents the sum of the deaths reported in a week divided by seven. The name “mobile” is why it varies according to the total number of deaths in the previous seven days.
