In Brazil, cases of simultaneous infection with two different variants of the new coronavirus in the same person have been identified. The discovery was made by a group of scientists from the National Laboratory for Scientific Computing, linked to the Ministry of Science and Technology that confirmed the possibility that a person could be infected by different mutations of SARS-CoV-2 at the same time.
These cases were discovered following a genetic study of samples from 92 patients in the state of Rio Grande do Sul, in southern Brazil.
In at least two of these samples, cases of simultaneous infection with different strains of the virus were recorded.
According to investigators, these two co-infected patients “had a mild to moderate covid-19 and recovered without the need for hospitalization” last November.
However, scientists say that this type of simultaneous infection is “worrying” because it mixes genomes of different variants that, ultimately, can result in the evolution of the virus.
