Assistant manager John Gorman told Sky Sports that goalkeeper Radek Cerny (pictured), and defenders Peter Ramage and Mikele Leigertwood, were affected by the contagious illness at various points since the summer.
"I'm afraid we have had two or three of the boys out with it," Gorman said.
"But we have just got on with it and kept them away from the club. Matthew Connelly has been out for ages with glandular fever and these sorts of things happen. We have just accepted that these injuries and these illnesses occur.
"Mikele Leigertwood had it and he came back into the squad last week. Peter Ramage and our goalkeeper, Cerny, were out with it right at the beginning of the season as well.
So the lads have done really well to recover and it's back to business again.
