South African coronavirus variant detected in reinfection case in Brazil
Brazilian researchers have identified the concerning new coronavirus variant first discovered in South Africa in a woman who contracted COVID-19 for the second time, and said it was the first such case reported in the world.
There have been other cases of reinfection in Brazil and the South African variant had previously been detected, but reinfection with this mutation of the virus is believed to be a first, researchers said.
The case involved a 45-year-old woman from the northeastern state of Bahia, researchers from the D’Or Research and Teaching Institute (IDOR) said, after carrying out a genetic sequencing of her viral infection.
“This mutation was recently identified in Rio de Janeiro, but it is the first time in the world that it has been associated with a reinfection by SARS-CoV-2,” Bruno Solano, who led the study, said in the statement.
“We observed, in the genetic sequence of the virus present in the second case, the mutation E484K, which is a mutation originally identified in South Africa and which has caused a lot of concern in the medical field, as it can hinder the action of antibodies against the virus,” Solano said.
