![Phylogenetic tree of partial sequence (256 bp) of Crimean-Congo hemorrhagic fever (CCHF) virus nucleoprotein gene. CCHF virus sequences are listed as viral strain name and country of origin. Sequence of case 3 is designated in the tree as “Gotse Delchev Bulgaria,” and sequence of case 4 is designated as “Bul 2008 Bulgaria” (in boldface). Strain AP92, Greece, was used as an outgroup. Numbers at the nodes represent bootstrap values. Scale bar indicates number of nucleotide substitutions per site.](/eid/images/08-1567-F1.jpg)
