The Tbilisi Grand Slam featured 464 athletes and 278 officials from more than 80 countries.

The build-up was marred by positive coronavirus cases with both the French and German teams forced to withdraw.

According to Frankfurter Allgemeine Zeitung, six men and one woman from the 31-person German team became infected.

It was also announced that the French team had withdrawn following a COVID-19 positive within its party.

The IJF has now put out a statement in response to what it described as "false information" regarding the Tbilisi Grand Slam, confirming there were 12 positives cases from more than 2,500 tests.

All participants were required to present two negative polymerase chain reaction (PCR) COVID-19 test results upon arrival, with both administered a minimum of 48 hours apart.

A further PCR test was then required, with participants remaining in quarantine until the result came back negative which allowed them to enter the competition bubble.

The IJF confirmed three athletes and three coaches tested positive after the third test and were placed in quarantine along with close contacts.

"As an additional layer of precaution and in accordance with the COVID Protocol, before each day of competition, the athletes that were competing underwent a fourth PCR test," a statement from the IJF read.

"There were six PCR4 positive cases, resulting in the same aforementioned protocols being employed.

"Out of over 2500 PCR tests that were administered, a total of 12 cases from PCR3 and PCR4 were positive. 

"While we are closely monitoring the health situation of these cases while they are quarantined, we are also working to verify, with our COVID Manager and local medical authorities, possible false positives for vaccinated athletes.

"Participants who need to, will also undergo a departure PCR test."

Ahead of the tournament, some national teams travelled to Tbilisi for a training camp where the IJF confirmed 12 athletes and three coaches failed the first and second COVID-19 tests conducted before they could enter the bubble.

"The positive results being identified and actions being taken to quarantine and provide medical services to these participants, is evidence that the system is working," the statement from the IJF added.
