A woman who was in an Austrian hospital to be tested for the coronavirus escaped from the premises, officials said.

Karl Schupfer, a press officer for the city of Salzburg, said the 31-year-old patient left the University Clinic Salzburg around 3 a.m. local time Wednesday morning and was found by police in her home near the city at around 10 a.m.

The unidentified woman had been in a hospital since Tuesday, Schupfer said, adding that her motive for escaping was unclear. She is now back in a Salzburg hospital under police watch and is being questioned. Her results are expected later on Wednesday.

Authorities are trying to find out who the patient may have had contact with during her escape. There are currently no confirmed cases of coronavirus in Austria.
