The group, made up of 18 boxers and seven other staff members, must now remain in quarantine at the training camp in Längenfeld in Tirol, DBV director Michael Müller said.
Without specifying numbers he said “a large part of the team” was affected but that everyone was doing well so far.
“The boxers are now in quarantine. They aren't showing strong symptoms and can even keep training,” Müller told AFP's SID subsidiary.
The athletes' conditions are being carefully monitored and they should be allowed to return home in the coming week, he added.
German weekly Der Spiegel had earlier reported that the boxers, who are training for the postponed Tokyo Olympics, started showing signs of a cold on Tuesday before suspicions of Covid-19 were confirmed on Wednesday.
The training camp was the team's first foray abroad since the start of the pandemic.
German media were quick to point out that the boxers were staying at the same Längenfeld hotel where Bundesliga football team Schalke 04 stayed in late August, and that one of their players also tested positive for the coronavirus while there.
Müller defended the decision to take the boxing team abroad, saying they had opted for Austria because the coronavirus numbers there were low at the time.
Like other European countries however, Austria has seen a sharp uptick in cases recently.
“We have gained some valuable experiences that we can use on our next trips,” Müller said.
“Anyone who thinks the preparation for the Olympics can happen without any coronavirus cases, is not living in reality.”
The 2020 Games were postponed in a historic decision earlier this year because of the pandemic, and they are now set to open on July 23rd, 2021.
