China News Service, February 1st. According to "Central News Agency", researchers in southern Brazil said recently that they found two confirmed cases of simultaneous infection with two variant new coronaviruses.
At present, the types of mutant viruses in Brazil continue to increase, and the situation is worrying.
According to reports, Brazilian researchers recently published the findings on the medical website medRxiv.
However, the research has not been published in scientific journals and has not been peer reviewed.

According to reports, both patients are in their 30s.
In late November 2020, they were infected with the P.2 mutant virus found in Rio, and the test also tested positive for another mutant virus.
The two reported mild symptoms, one of them had a dry cough, and the other had symptoms such as cough, sore throat and headache.
None of them need to be hospitalized.
The report pointed out that two cases showed that there may be multiple variants of the new coronavirus spreading in Brazil.
This also worries scientists that the existence of two virus strains in the same person may accelerate the mutation of the mutant virus.
The lead researcher of the study, Fernando Spilki, a virologist at Feville University, said, "This simultaneous infection may cause the virus to combine, and even produce a new variant virus faster than before." "This will become another virus. Kind of evolutionary path."
According to the report, the emergence of new mutant viruses not only brings the risk of increased infectivity, but may also invalidate the vaccine currently under development.
The mutated viruses discovered in the UK and recently in Brazil seem to be more transmissible.
