The US Centers for Disease Control and Prevention (CDC) said the study suggested that human infection by the G4 virus is more common than it was thought to be. Both the European Centre for Disease Prevention and Control (ECDC) and the US CDC stated that, like all flu viruses with pandemic potential, the variant is a concern that will be monitored. The ECDC stated that "the most important intervention in preparing for the pandemic potential of influenza viruses is the development and use of human vaccines ...". Health officials (including Anthony Fauci) have said that the virus should be monitored, particularly among those in close contact with pigs, but it is not an immediate threat. While there have been no reported cases or evidence of the virus outside China as of July 2020, "Smithsonian Magazine" reported in July 2020 that scientists agree that the virus should be closely monitored, but because it "so far cannot jump from person to person", it should not be a cause for alarm yet.
