Adrian Taylor says he spent the weekend "in hell" after being struck down by the flu four days ago.

"It's been hell, I have lost about four kilos and haven't left the house.

"I've had fever, have not been able to move or get out of bed, I've had headaches, coughing and I got tonsillitis that was brought on by the flu."

The 33-year-old health and safety manager from South Melbourne said he received the flu vaccination, but it did not stop the vicious virus.
