JERUSALEM (AP) -- Prime Minister Naftali Bennett said Israel is "on the threshold of an emergency situation" on Friday after authorities detected the country's first case of a new coronavirus variant in a traveler who returned from Malawi.
The Health Ministry said the traveler and two other suspected cases, all of whom had been vaccinated, were placed in isolation.
A new coronavirus variant has been detected in South Africa that scientists say is a concern because of its high number of mutations and rapid spread among young people in Gauteng, the country's most populous province.
At a Cabinet meeting convened Friday to discuss the new variant, Israeli Prime Minister Naftali Bennett said it is more contagious and spreads more rapidly than the delta variant. He said authorities were still gathering information on whether it evades vaccines or is deadlier.
"We are currently at the threshold of an emergency situation," he said. "I ask everyone to be prepared and to fully join in the work around the clock."
Late Thursday, Israel declared South Africa and six other African nations to be "red countries" from which foreign nationals are barred from traveling to Israel. Israelis are prohibited from visiting those countries and those returning from them must undergo a period of isolation.
Israel launched one of the world's first and most successful vaccination campaigns late last year, and nearly half the population has received a booster shot. Israel recently expanded the campaign to include children as young as 5.
But the country only recently managed to contain a wave of infections driven by the highly contagious delta variant.
Israel has reported at least 8,182 deaths since the start of the pandemic. It currently has more than 7,000 active cases, including 120 who are seriously ill, according to the Health Ministry.
