The Slovak government has ordered a 14-day ban on all cultural, sporting and other events organised by public authorities to avoid the spread of coronavirus, casting into doubt the prospect of the Republic of Ireland facing Slovakia in their Euro 2020 play-off semi-final in Bratislava in 17 days' time.
Seven cases of the infection have been documented in the country so far, with many schools and amenities already closed to the public.
The Slovak Football Association has said it will fully respect any potential decision by the country's health officials in relation to playing the game against Ireland behind closed doors, but that may now represent a best-case scenario.
The FAI has also released a statement, saying it is in contact with Government, Slovakian authorities and UEFA, but "as of today, Monday, the game is scheduled to go ahead as planned".
Refunds will be issued to supporters if the match is played without fans or cancelled.
Around 2,200 Irish fans have bought tickets for the game.
There were 4,500 applications, so it is expected some fans may travel without tickets.
The FAI is in communication with Slovakian FA and local authorities, as well as UEFA and the Irish Embassy in Slovakia.
"The FAI will continue to heed the advice of the Irish Government and UEFA in relation to this game and will relay any news around the fixtures to supporters and staff as soon as it becomes available," said the association in a statement.
