Traces of the Delta COVID-19 variant have been detected in the sewer system of the southern Israel's coastal city of Ashkelon, the Israeli Ministry of Health said on Thursday.
This result raised concerns that certain residents in the city have been infected with the variant, the ministry said in a statement.
Following the detection, the ministry called on anyone suffering from fever, cough and weakness, or fearing of being infected, to take a coronavirus test as soon as possible to prevent an outbreak in the city, which has more than 140,000 residents.
Earlier on Thursday, the ministry again urged teenagers aged 12 to 15 to be vaccinated against the coronavirus.
