Health officials report the first identified case of the AY.4.2 Delta variant in Israel. The variant has been seen recently in several European countries.
The patient is an 11-year-old boy who tested positive when returning from Moldova.
Officials are investigating whether the new strain is more virulent than Delta, though they have yet to express serious concerns over it.
Earlier, a spokesman for British Prime Minister Boris Johnson said there was no evidence that AY.4.2 spreads more easily.
