Figure 5From: Measles Resurgence Associated with Continued Circulation of Genotype H1 Viruses in China, 2005Phylogenetic tree of Chinese representative MV strains from 1993 to 2005 and the representative MV strains of H1 genotype based on the 456 nucleotide sequences coding for the COOH-terminus of the nucleoprotein. Three main variants (A, B and C) of cluster 1 genotype with the identical sequence for each variant were identified in mainland and Taiwan of China and Japan from 2000-2005. MeV strains of variant A were isolated from both China and Japan, 2000-2005. Variant B and variant C caused the measles continuous circulation in Mainland China and Japan from 2000-2005, and in Mainland and Taiwan China from 2002-2005, respectively. Sequences of Taiwan, South Korea, Japan and Vietnam obtained from GenBank, GenBank accession numbers are also shown for each strain.Back to article page
