A study done by about one hundred thousand people estimates that there are more than eight million entrusted in Brazil

He Brazil it would have at least eight million people entrusted by covid-19, five times more than government figures, according to a study commissioned by the health ministry and which examined blood samples from 89,397 Brazilians in one hundred and thirty-three cities in the country.

The study shows the high rate of underreporting of cases of the disease in Brazil. 3.8% of those examined between 21 and 24 June had antibodies against the disease in their blood samples, ie they had been infected or had already come into contact with the virus that transmitted the virus. disease. By projecting this percentage, the researchers estimate that if this percentage had antibodies, at least eight million would have been infected at some point in the last four months.

The study was conducted in three stages (second half of May, first half of June and second half of June) and showed that the number of infected increased by 23% between the second and third stage, less than 53% measured between the first and second stage.

The assignments have doubled in a month

While in the first stage the percentage of entrusted was 1.9% of those analyzed (about four million), while in the third phase is already eight million. ‘It’s an excellent result because we had measured a 53% increase between the first and second phase, which is a giant leap, and that growth has already slowed. Ideally, it should be less, but it is already a victory, ‘said the rector of the Federal University of Pelotas. Pedro fish, university that have conducted the research.

Beyond the underreported, the study shows that it is increasing more among the poor, the afrodescendent and indigenous people, who have three times higher rates of infection than whites with more resources. Among the afrodescendent, the percentage is 5.6%, among the natives 5.4% and among the whites 1.1%. At the same time, while between the richest 20% 1.8% have been entrusted and between the poorest 20%, it is 4.1%.
