A ship had an outbreak of the Hanta virus. In Austria, authorities look for 3 contact persons. These people flew in a plane with a sick woman. The sick woman died later.
The authorities found the second person now. This person has no symptoms. The risk for an infection is very low. The person works well with the authorities.
A third contact person is still missing. This person is not registered in Austria. That makes the search very hard. No one knows if the person is in Austria.
There is no Hanta virus case in Austria so far. The rules for reports are stricter now. Doctors must report suspicious cases at once. Contact persons watch themselves for 6 weeks.
Contact persons must call a doctor if they feel sick. They must avoid places with many people. This includes nursing homes or hospitals. They must wear masks in rooms with many people.
