(CNN) -

If good control over the spread of coronavirus in the community is not achieved and more people are not vaccinated, then there may be another variant that is worse than delta, said Dr. Anthony Fauci, director of the Institute. National Allergy and Infectious Diseases, to ABC's George Stephanopoulos on Good Morning America, Thursday.

"That will happen, George, if we don't get a good grip on the extent of the community," Fauci said when asked if the United States faces a continuing cycle of new variants.

“And as long as the virus continues to spread, it gives it ample chance to mutate, and when it gives it ample chance to mutate, sooner or later it may get another variant, and it is possible that that variant will be in some ways worse than the already very bad variant. difficult we are dealing with now, ”he said.

"This is one of the main reasons you want to completely suppress the circulation of the virus in the community."

That's why he and his colleagues keep saying how important it is to vaccinate as many people as possible.

"People say I don't want to get vaccinated because it's me and I care about myself, I'm not impacting anyone else, it's just not the case," he said.

"Because when people are not vaccinated, they allow the virus to circulate in the community, and when it does, even if it does not make a particular individual sick, they may be asymptomatic, that person is still a vehicle for spreading to other people" .
