Sunday’s game saw 60,000 fans return to Wembley stadium in London as England played Italy last Sunday. No social distancing rules were in place and face mask wearing was not mandatory.
However, ticket holders were required to produce a negative coronavirus test to attend the event in a Government pilot to assess the impact of large-scale events.
One fan, who is now self-isolating, told i: “Pretty much every group I know of has at least one positive or isolating.
“It just seems like pretty much everybody caught it.”
Another fan reported that everyone he had attended with contracted the “Wembley variant”.
One person claimed to have taken a lateral flow test on Sunday which had a negative result but tested positive the day after the match.
He wrote in a social media post seen by i: “Goodness knows who got it off me, crammed like sardines in Wembley Park after the game Sunday and the Tube itself and the trains.”
The World Health Organisation (WHO) has criticised the "devastating" lack of coronavirus precautions during the Euro 2020 final.
Maria Van Kerkhove, coronavirus technical lead for the WHO, described "watching transmission happening in front of my eyes”.
