An employee in Israeli Prime Minister Benjamin Netanyahu's office has tested positive for the coronavirus, his office said, without saying whether the 70-year-old leader had been exposed.

A statement from Netanyahu's office said an “epidemiological investigation is being conducted, which will provide appropriate guidelines for those who came into contact” with the employee.

Netanyahu has previously self-isolated after two separate Covid-19 scares — first in March after coming into contact with an infected aide, and later in April after his then-health minister was diagnosed with the virus.The premier tested negative for the virus on both those occasions.
