(*)A case is considered serologically confirmed if testing reveals an indirect fluorescent antibody (IFA) titer of [is greater than or equal to] 1:64, a complement-fixation (CF) titer of [is greater than or equal to] 1:16, or a fourfold rise in titer by the CF, IFA, microgglunatination (MA), latex agglutination (LA), or indirect hemagglutination (IHA) assays.
Samples with a hemagglutination inhibition value [greater than or equal to]1:10 were considered positive.
As recommended by WHO, samples that were antibody-positive by MN underwent confirmatory testing by hemagglutination inhibition assay with horse erythrocytes or by H5-specific Western blot analysis (9,10).
