Bolton Wanderers manager Gary Megson has claimed that four members of his first-team squad have suffered from the swine flu virus in the past.
On Monday it was revealed that several players in the Blackburn squad were suffering from the ailment and Rovers boss Sam Alladyce has since said that Chelsea players could suffer in the future.
Allardyce's side lost 5-0 to Chelsea on Saturday after which he confirmed three of his players were ill with the virus.
Bolton play Chelsea in the Carling Cup fourth round on Wednesday, but when asked if he was worried about his players coming into contact with players who potentially had the virus, Megson said:"Not from that perspective because I've heard varying opinions.
"I think the one we all need to listen to is that from the medical people, who are saying that it is very difficult, if not impossible, to contract it in that way.
"From our own point of view, you're not going to be a business with quite a few employees and it totally escapes you.
"You are going to get one or two with swine flu and I think on the playing staff I think we have had five, four players and one member of staff.
"You try and do your best to avoid it but I would imagine it's near enough impossible. They are all okay at the moment, but it wouldn't be right to start giving you names."
