Change of antiviral prescription and strategy of Influenza A(H1N1) 2009 The Ministry of Health, Welfare and Family Affairs became higher the National Disaster Phase from 'Concern(Blu)' to 'Severe(Red)', but the phase was downgraded to 'Alert(Orange)' starting on December 11. As the strategy of Influenza A(H1N1) change, Korea CDC has been making the revised editions of Influenza A(H1N1) Control and Prevention guideline up to sixth edition. After antiviral prescriptions peaked during Week 44-46(Oct.26~Nov. 15), the number has been declining to date. 101 105 108 110 Public Health Weekly Report, KCDC 101
