The free testing is available immediately.
There are an estimated 30,000 people with no health insurance living in Austria, most of whom live in Vienna.
The coronavirus pandemic is causing the number of uninsured people to rise, experts have warned. People without insurance may include homeless people, refugees, asylum seekers and the destitute.
Due to the fact that they are not insured, they do not have an e-card and as a result have no access to the health system.
Austria has also made it possible for for people without health insurance to access free healthcare.
This is available at institutions such as Ambermed in Liesing, the Order Hospitals in Vienna or the Neunerhaus in Margareten.
