9 cases/100 soldiers tested: RVF (n = 20), AHFV (n = 13), CCHV (n = 6), and DENV (n = 1) (Table).
Analysis of the province of origin provided AHFV epidemiologic information (Figure).
savignyi tick) is a vector and reservoir of AHFV in Saudi Arabia.
Previous analysis of KFDV and AHFV suggested slow evolution with divergence [approximately equal to]33 years ago (10).
7% homology at the nucleotide level with AHFV strain 1176 (GenBank accession no.
Pairwise distance comparison with AHFV prototype strain 1176 sequence showed 0.
Sequences from the 11 AHFV
isolates were compared with homologous sequences representing other tickborne flaviviruses retrieved from the GenBank database: Langat virus (LGTV) (M73835), Powassan virus (POWV) (L06436), deer tick virus (DTV) (AF311056), Omsk hemorrhagic fever virus (OHFV) (AY323489), Kyasanur Forest disease virus (KFDV) (AY323490 for envelope sequence, and personal data for NS3 and NS5 sequence), tick-borne encephalitis virus (TBEV) Neudoerfl strain (U27495), Hypr strain (U39392), Vasilchenko strain (L40361), Sofjin strain (AB062064), and Louping ill virus (LIV) (Y07863).
