“It has just been confirmed that Rupert Grint has taken a few days out of filming due to a mild bout of swine flu,” the publicist’s statement said, according to this article by the AFP.

“He has now recovered and is looking forward to joining his fellow cast members at the junket and premieres this week and will then return to filming directly afterwards.”

So, it’s clearly so serious that he will still attend the premiere of Harry Potter and the Half-Blood Prince and “risk” infecting his co-stars. The urgency of swine flu is renewed!
