Average of deaths by Covid in Brazil remains below 500

The moving average of daily deaths caused by Covid-19 in Brazil fell once again this Thursday (9/9), reaching the rate of 465.7. With the result, the indicator registers the lowest number since November 13, 2020, when it was at 418.7.

Compared to the rate seen two weeks ago, there was a 32.3% retraction. It is the 18th day in a row that the downward trend in deaths is maintained.

In the last 24 hours, 753 deaths and 30,891 new infections were reported 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 585,174 lives to the disease and computed 20,958,899 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)Data, the large volume of information analysis 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.
