UEFA is treating the event as a pilot to bringing fans back to stadiums. Those in attendance must abide by social distancing of one-and-a-half meters, wear face masks and undergo a body temperature check on entry.
On its website, Bayern emphasized that fans traveling back from Hungary to the state of Bavaria, where the club is based, will have to quarantine for 14 days.
The club is also offering fans returning from Budapest a free coronavirus test in the car park of its home stadium, the Allianz Arena.
Sevilla and Bayern have each been allocated 3,000 tickets with the remainder likely to be taken by locals as Hungary hosts a final of a major European football competition for the first time.
Hungary’s National Ambulance Service has announced that 500 emergency service workers have been invited to Thursday’s game, with those tickets selling out in 21 hours.
“The measures are strict and there is not a question of health risks for the fans,” UEFA president Aleksander Ceferin said in a press conference on Thursday.
“We want — and health is the number one priority — to bring hope, to do what we think is the proper thing to do.
“Don’t think we are doing this because of money because we don’t get any revenue, we get more costs with it. But fans and players are the essential part of football. We (UEFA) are just accompanying persons.”
In a statement on Wednesday, the Hungarian Football Association noted that the game will be less risky than indoor events and safer than crowding on a street.
“Thanks to strict precautions, the Puskas Arena will be a safer venue than any other point in the country or even the whole of Europe at the time of the match,” it said.
The match comes in the same week that the UK government has postponed plans to allow fans back into sports grounds from October 1 amid a second wave of infections.
Sevilla is yet to get its La Liga campaign underway this season, although the team is in good form having last suffered defeat in February. Bayern, meanwhile, started its domestic season with an 8-0 thumping of Schalke.
