Early this year, scientists in Brazil reported that two people were simultaneously infected with two different variants of SARS-CoV-2, the virus that causes COVID-19. It has raised questions about how these viruses may interact in an infected person, and what it could mean for generating new variants. An infected person does not infect everyone with whom he or she comes in contact. Therefore, a person meeting more than one infected person during a short period of time, and getting the virus from all of them, have a statistically lower probability. Additionally, all the current vaccines have been found to be nearly equally effective against the different variants of the coronavirus.
