Manager Tim Sherwood has provided a fitness update on his squad ahead of the weekend's clash with Sunderland at Villa Park.
Sherwood declined to say who exactly was suffering with the illness but did reveal that two players are serious doubts for the game, with a few others had been unable to make it to training.
Villa suffered a similar issue at the start of last season when a virus sidelined several members of Paul Lambert’s squad before the 3-0 home defeat to Arsenal in September but the new boss is hoping that the individuals in this instance will be able to make it back in time.
"There's a sickness bug around the training ground so there are a few players who have not been able to make training," said Sherwood. "We have a couple of players, I don't want to tell you who they are but they're not here today because they are ill.
"They are not well today and the doc is having to do some overtime. We could miss a couple and there's a couple who are not well now. I'd rather they weren't well now rather than tomorrow.
"There must be a bug going around, we're just hoping it's made its way to the north-east."
Meanwhile, Sherwood also provided an update on the ailing Adama Traore, who was forced off an hour into Tuesday night’s 5-3 Capital One Cup win over Notts County after taking a knock to his ankle.
The 19-year-old winger, who scored his first goal for the club in the victory, has not been able to train since but the Villa boss believes there is still a chance he could feature on the weekend.
“Adama has not trained since Tuesday - and he won't train today,” added Sherwood. “But we will give him every chance to be fit. But we aren't going to know until tomorrow morning.
"He took a few kicks the other night. He tried to carry on but he's a marked man.”
Saturday’s game at Villa Park could also see Scott Sinclair start over the struggling Gabby Agbonlahor after the winger staked his claim for a regular place in the line-up with a hat-trick against Notts.
