Moving average of deaths by Covid-19 in Brazil drops to 711.9

The moving average of daily deaths caused by Covid-19 in Brazil dropped to 711.9 this Wednesday (25/8). With the index presented, the country completes the fifth day in a row below the level of 800 daily deaths. In addition, the indicator registers the lowest value since January 6 of this year, when it was 683.1.

Compared to the rate seen two weeks ago, there was a 19.5% retraction, which signals a drop in the number of deaths.

In the last 24 hours, there were 903 deaths due to the virus and 30,671 newly infected people were notified across the country. The data are in the most recent balance released by the National Council of Health Secretaries (Conass).

In total, Brazil has already lost 576,645 lives to the disease and computed 20,645,537 cases of contamination.

Check out the history of the pandemic in the country in the chart below:

Due to the incubation time of the new coronavirus, the recommendation of experts was adopted that the moving average of the day be compared to that of two weeks ago.

Variations in the number of deaths or cases of up to 15%, more or less, are not significant in relation to the evolution of the pandemic. Percentages above or below, on the other hand, should be seen as an upward or downward trend.

The calculations are made by (M)Dados, the data journalism center of the metropolises.

Moving average

Tracking the progress of the Covid-19 pandemic based on absolute death or case data is far from ideal. This is because they can have very large daily variations, especially delays in registrations. On weekends, for example, it is common to notice a significant reduction in numbers.

To reduce this effect and produce a more accurate view of the scenario, moving average is widely used around the world. The rate then represents the sum of reported deaths in one week divided by seven.

The name “mobile” is because it varies according to the total number of deaths from the previous seven days.
