Covid 19 in Brazil and the plateau
29
Jun
The analysis based on the number of infected cases is not feasible because
testing in Brazil is still small, done by companies or hospitals but only in cases where there is a suspicion of the need for hospitalization, and the estimate that 5% of deaths would correspond to the number of infected is not true because the isolation measures are different in several regions.
The plateau that started from the middle to the end of May has lengthened because the regions with the highest number of infected people were widening and in the case of Brazil going inland, called the epicenter, the name would be inappropriate if there was isolation, thus the contamination spread.
In addition to there being no isolation from the regions where infections started, which has been done in many countries since China where it started and the Wuhan region was epicenter, in this case the name is justified, both local measures and isolation regions were hard to contain the spread.
The second question is how to look at the graph and the numbers, the graph that at the beginning was an exponential and although it is necessary to look at making a logarithmic scale of the curve to see the degree of slope (for example, at the beginning, the number doubled every day and then every other day, etc.), now that the curve no longer has an exponential behavior, it is necessary to make the logarithm.
Looking at the logarithmic scale of the curve, the plateau is clearly perceived (graph above) and the numbers are rotating slightly above the thousand daily cases of death, the degree of infection as already said is not necessary, and thus it is perceived the plateau that has been going on for a month.
The reason was the initial analysis done here, with no isolation from the regions, the virus spread to more inland regions and the new “epicenter” is the interior of the country, and so it should continue into the month of July, either because of the ineffectiveness of isolation policies , or for the winter period
