Nine more COVID-19 cases have been detected among the Munster rugby team currently in South Africa.
One player had previously tested positive.
However, the team says nine more staff and players have tested positive in the latest round of PCR testing.
All ten team members who've tested positive will stay in a dedicated quarantine hotel in Cape Town.
38 other staff and players have returned negative results, but are continuing to individually isolate in their rooms.
South African authorities have given those with negative test results the all-clear to travel.
However, Munster says the team is to undergo another round of PCR tests before the "next steps".
In a statement, Munster said: "The ten members of the group who have tested positive will remain in Cape Town until the end of their isolation period.
"While the individuals were disappointed on receiving the news they are thankfully well and will continue to be monitored medically at this time.
"We understand this is a challenging situation and would like to thank families, friends, colleagues and our rugby community for the many messages of best wishes."
Those who do return home will need to self-isolate for ten days, due to the new travel restrictions in place in Ireland over Omicron variant concerns.
