Researchers announced Wednesday that an average of 15% of Brazil’s 210 million people have COVID-19 antibodies.
The study was conducted until the end of April, when the transmission was on the rise, with the support of the São Paulo State Government Research Foundation (Fapesp) and the Federal University of São Paulo (Unifesp).
Researchers have found that antibody levels vary widely across countries.
For example, in the northeastern state of Ceará, 9.89% had antibodies, while in the northern state of Amazonas, 31.4%, they were severely attacked by the virus and spawned a new homemade variant known as P1. I did.
“These results show that there are many spatial variations in the epidemic. There are several epidemics in Brazil, not just one,” said Marcelo Brack, a senior researcher who is a professor at Unifest. Tini says.
The presence of the COVID-19 antibody suggests that at some point it is likely that you have been infected with the virus, which may mean that you are immune.
Brazil has been severely hit by the virus, killing more than 450,000 people and the second highest in the world after the United States.
After months denying the severity of the virus, President Jair Bolsonaro has been widely criticized for dealing with pandemics, slow vaccine deployment, and spots.
The survey tested 120,000 people in 133 municipalities nationwide between January 25 and April 24.
According to Brattini, the majority of people have not yet been vaccinated due to the concentration of tests from January to mid-February, when the national vaccination program was just beginning.
“Less than 1% of people tested said they were vaccinated, and virtually no one was vaccinated with both,” Burattini said.
