France's head coach Fabian Galthie has tested positive for Covid-19, the French rugby federation said, after the country's Six Nations squad went into isolation following another staff member's positive test.
Galthie had previously returned a negative result but he was re-tested later on Tuesday and was found to be positive for the virus.
The federation did not say where the squad is isolating.
It said in a statement that additional tests will be conducted at the National Rugby Centre on Wednesday, with more tests to be conducted on Friday and one more round of testing at the national centre on Sunday.
Earlier today, the IRFU has confirmed that all members of the Ireland squad and backroom team have tested negative in their latest PCR testing after news of a positive case in the French camp.
The IRFU issued a statement to RTÉ Sport to clarify the latest round of tests for the Irish camp.
"All members of the Ireland squad and backroom team undertook routine PCR testing on Monday producing no positive results. The group will undergo further routine testing again this week as per our protocols."
Ireland will seek a first win of the competition in Rome on Saturday week, 27 February, while the following day Fabien Galthie's men host Scotland in Paris.
Meanwhile Ireland will retain a 24-man panel for the two-day mini-camp at the IRFU High Performance Centre at the Sport Ireland Campus, with a total of 12 players are returning to their provincial bubbles to avail of game time in the Guinness Pro14 this weekend.
