A home housing refugees in western Germany has been hit by a coronavirus outbreak, a Cologne district government press officer told CNN.

The refugee accommodation in Sankt Augustin, Germany recorded its first case last Friday, Vanessa Nolte said. Since then 120 refugees, out of a total of 489 who are registered there, have tested positive.

Only 312 of the residents were actually tested for coronavirus, as the inhabitants are not confined to the home, but can come and go, Nolte said. In addition, 10 staff members have tested positive for the virus, she said.

The refugees are mostly young people and families, Nolte said; she could not give information on their nationalities.

The refugee accommodation was immediately put into full quarantine, meaning no one could enter or leave, and authorities are in the process of separating the positive from the negative cases.

This is proving challenging as some of the inhabitants do not want to be moved, the press officer added.
