The pneumonia (novel coronavirus disease, COVID-19) Epidemic in Wuhan has been extended, Brazilian researchers recently found that patients in the country were infected with two different strains of the Variant virus at the same Time, experts worry that the virus may accelerate mutation and may become resistant to the vaccine.
The study points out that two patients in their 30s in Brazil were infected with the Brazilian variant of the virus in late November, and after investigation, the patients were found to be diagnosed with another variant of the Brazilian virus at the same time. According to the report, both were mildly ill, one with a dry cough and the other with a cough, sore throat and headache.
Experts believe that these two cases show that there are multiple mutated strains of the virus circulating in Brazil and are concerned that having two mutated strains in the body at the same time may accelerate the mutation of the martial lung virus and create new mutated strains. The lead researcher, Fernando Spilki, a virologist at Feevale University, said that the presence of repeated infections could lead to accelerated mutation of the virus. He then added that this could be another way for the virus to evolve.
The Wuhan pneumonia virus now has multiple mutations, including the British strain, the South African strain and the Brazilian strain, which have recently spread rapidly to various countries, and the new variants not only pose a greater risk of transmission, but may also be resistant to vaccines already developed. The study of the simultaneous diagnosis of two mutated strains has not been published in a scientific journal and has not been confirmed by other research teams.
