The outbreak has heavily hit the north of Italy, where Juventus are based, and on Sunday it was confirmed that there were five new fatalities from the illness in the country.
Juventus had their last game against Inter Milan suspended at the weekend due to the issue.
It was also recently announced that no games will take place in the impacted areas until March 8.
Lyon are meant to take on Juventus in Turin on March 17 in the return leg of their last-16 match, with the French side 1-0 ahead.
And on Monday Jean-Michel Aulas admitted the second game could be held in a neutral venue amid fears over Juventus’ Under 23s.
‘UEFA will decide where we play,’ the Lyon president told L’Equipe. ‘There are some new elements to evaluate because Juventus’ Under 23 team has been quarantined.
‘They are worried about four players. And the reserves train with the first team.
‘We’ll see what happens. I’ll wait to hear what UEFA says.
‘I hope good news arrives and, in the worst case, it can’t be excluded that we play in a neutral ground.’
