World Health Organization officials said Monday that the Delta coronavirus variant was the fastest-moving and "fittest" variant to date, with the ability to find and kill the weakest people.

At a Monday news conference, Dr. Mike Ryan, the executive director of WHO's health-emergencies program, said Delta had the potential "to be more lethal because it's more efficient in the way it transmits between humans," according to CNBC.

He said the Delta variant "will eventually find those vulnerable individuals who will become severely ill, have to be hospitalized, and potentially die."

"This particular Delta variant is faster, it is fitter, it will pick off the more vulnerable more efficiently than previous variants, and therefore if there are people left without vaccination, they remain even at further risk," Ryan added, according to CNBC.
