|Subject: TAMIFLU RESISTANCE IN SWINE FLU Fri Jul 03, 2009 8:50 am|| |
For the first time, the National Health Board of Denmark has announced a
case of pandemic H1N1 flu resistant to the antiviral drug Tamiflu. However, the board has claimed, “there is no evidence" that the virus has spread.
While the case is likely to be isolated, the discovery has led to calls questioning the policy in most European countries of giving low doses of Tamiflu to people in contact with infected people. The Danish case, a contact of someone who caught swine flu abroad, was given Tamiflu as prophylaxis to prevent her getting sick, but she still developed symptoms.
Later she took Relenza, another antiviral drug, and recovered. The State Serum Institute in Copenhagen found that her virus carried a mutation giving resistance to Tamiflu. Thus, they are thinking that the resistance emerged during treatment rather than having been there already.National Health Board of Denmark has announced a case of H1N1 flu resistant to Tamiflu
