First, as reported by the BBC, a Denmark patient with the swine flu bug is showing signs that the drug Tamiflu is not working.
Experts have reported the first case of swine flu that is resistant to tamiflu - the main drug being used to fight the pandemic.
Roche Holding AG confirmed a patient with H1N1 influenza in Denmark showed resistance to the antiviral drug.
But in other news, the CDC is saying the drug Tamiflu still works on swine flu.
ZURICH (Dow Jones)--Roche Holding AG (ROG.VX) and the Atlanta-based Centers for Disease Control and Prevention said they still consider Tamiflu effective against the A/H1N1 "swine flu" virus, even though a patient in Denmark developed resistance to the drug.
"Such a development had to be expected and is no surprise from a scientific point of view," David Reddy, Roche's Pandemic Taskforce leader told journalists on a conference call.
And the WHO is saying the case in Denmark is an isolated case.
Both organizations have said the H1N1 virus has not mutated when in fact it has.
