  According to reports, the two patients found by researchers in southern Brazil were both in their 30s.

Both had mild symptoms and did not require hospitalization.

  The lead researcher of the study, Fernando Spielki, a virologist at Feville University, said: "These simultaneous infections of two viruses may lead to a combination of viruses, causing the viruses to mutate faster than we know. body."

  The new variants pose a greater risk of transmission and may develop resistance to vaccines currently under development.

  Spirki said these cases show that there are currently a large number of different viruses circulating in Brazil, because only in this case will there be cases where patients are infected with two viruses at the same time.

  According to the epidemic data released by the Brazilian Ministry of Health on the 28th local time, the cumulative number of confirmed new crown cases in Brazil has exceeded 9 million.
