  7. NIC’s response & activities during early containment phase(25 April-Mid May) • NIC developed a nested PCR and sequencing method for NA gene with good sensitivity: confirmed 3 pandemic (H1N1) 2009 cases • NIC did a contingency plan and identified 5 bottle necks: test result reporting; specimen reception; automation; testing algorithm; technical staff

  8. NIC’s response & activities during late containment phase(Mid May-21 June 2009) • Highest sample volume: • For a week: ~1000 samples • For a day: ~350 samples • High political commitment: mobilize resources from MAF IDC, AgResearch, ESR CD group; • Test for Pacific Island countries: Cook Island, Samoa, Togan

  9. NIC’s response & activities during management phase(22 June-present) • Viral culture and antigenic typing • Tamiflu resistance monitoring • Investigation of coinfection of pandemic A(H1N1) and seasonal A(H1N1) cases • Full genome sequencing for fatal and ICU cases • Potential sero-survey
