Vienna, Burgenland, Salzburg, Carinthia, Styria, Lower and Upper Austria have all extended the quarantine period from ten to 14 days.
Quarantine is being extended in these federal states because of virus variants, increasing case numbers and more intensive care patients.
The Brazilian and South African variants have been detected in Austria and the British variant is becoming dominant. This means longer quarantine times are needed.
In Burgenland, 88 percent of new infections are due to the British coronavirus mutation.
Experts believe that the British coronavirus mutation has a higher viral load, which means people can be contagious for a longer period.
Is it still possible to leave quarantine early?
Similar to the previous ten-day quarantine, it is possible to leave the 14-day quarantine early with evidence of a negative coronavirus test.
The quarantine can be ended on the tenth day with evidence of a negative coronavirus test.
This can be with either a negative PCR test or an antigen test.
According to Austria’s Der Standard newspaper, people are also allowed to leave quarantine after ten days if they have not had symptoms of the virus for at least 48 hours and can demonstrate a CT-Value which is above 30.
People can also leave quarantine from the tenth day if their CT-Value is above 30.
