ロイター通信の記事(抜粋)

JERUSALEM: Israel empowered health officials on Wednesday to quarantine anyone deemed to have been exposed to an especially infectious variant of Covid-19, even if they were previously vaccinated or recovered from the disease with presumed immunity.

The decision followed a warning by Prime Minister Naftali Bennett on Tuesday over new outbreaks caused by the Delta variant, with daily infections rising after weeks of low plateau credited to Israel’s record mass-vaccination drive.
