A soldier from Schwaz in Tyrol, the source of the original outbreak of the virus , returned to the Upper Styrian barracks from home leave in mid-January.
He and another soldier had symptoms on January 25th and tested positive. The sequencing of these two tests now showed that it is the B.1.351 mutation of the coronavirus, according to the armed forces.
Immediately afterwards, a total of nine people from the barracks tested positive for the coronavirus, of whom three had been in contact with the pair who were originally infected.
Six other soldiers had been infected from another source, Gerhard Schweiger of the Styrian military command told ORF.
The sequencing of these tests is not yet complete, so there may be more cases of mutation detected. Further results are expected in the next few days.
Following quarantine, the solder from Tyrol was tested again on 3rd February at which point the virus was no longer detectable, and he is now back on duty. The second soldier is still showing as infected and is in quarantine.
The military command said all infected persons at the Aigen site were in the management team.
With the exception of one infected person, all have so far either been symptom-free or have only had a mild course.
On Tuesday, all 300 people stationed in Aigen im Ennstal were given PCR tests, according to the armed forces.
