Djokovic said he knew of his Covid-positive test result on December 16 in a sworn affidavit published by the Federal Circuit Court of Australia Monday.
“On 16 December 2021, I was tested and diagnosed with SARS-CoV-2 (COVID),” Djokovic’s affidavit read.
Multiple images posted by the Novak Djokovic Foundation's social media accounts show Djokovic, who wasn't wearing a mask, participating in a panel discussion in front of an audience on the same day.
Djokovic and the participants were not wearing masks in the images.
On December 17, the Belgrade Tennis Association's Facebook page then posted various photos of Djokovic posing with a group of young people at a tennis awards ceremony.
One photo shows at least 26 mostly young people posing with him. Local Serbian media widely reported that Djokovic participated in the youth awards event.
On the same day, Djokovic later posted a photograph of himself with a plaque on his official Instagram account.
The headline of this post has been updated to reflect that Djokovic knew of his positive test one day before the December 17 event.
