Genetic features of Orthonairovirus haemorrhagiae variants detected in ixodid ticks in Armenia.

ABSTRACT:

Introduction

Crimean-Congo hemorrhagic fever (CCHF) is a viral transmissible febrile disease, featuring hemorrhagic manifestations and a high mortality rate, caused by Orthonairovirus haemorrhagiae (CCHFV). CCHF is endemic in the Republic of Armenia (RA) and neighboring countries. Currently, there is no genetic information on CCHFV circulating in the RA. This work presents the results of genetic identification of CCHF viral variants detected in ixodid ticks collected in 2022-2023.

Methodology

Ixodid ticks were collected from cattle, horses, and vegetation in seven Armenian regions (Vayots Dzor, Gegharkunik, Kotayk, Lori, Syunik, Tavush, Shirak). Tick pools were tested for the presence of CCHFV RNA by RT-PCR. Genetic identification of CCHFV isolates was performed based on par
