Harry Potter star Rupert Grint was terrified when doctors told him he had swine flu, but relieved to find his only symptom was a sore throat.

The actor was recently forced to take time off from filming Harry Potter and the Deathly Hallows, which is currently shooting in Britain, after contracting the virus.

The 20 year old was initially alarmed when he first heard the diagnosis - but he insists the bout was no worse than a common cold.

He explains, "I did have swine flu, but it was just like any other flu I've had before. It was just a sore throat and I was in bed for a while, but it was quite scary when I was first told I had swine flu because of what's been in the press."

He joked: "I was like, 'Am I going to die?' But it was fine - just a sore throat."

Grint has now recovered and is currently promoting the sixth movie in the franchise, Harry Potter and the Half-Blood Prince.
