Host genetic diversity contributes to disease outcome in Crimean-Congo hemorrhagic fever virus infection.

ABSTRACT: The Crimean-Congo hemorrhagic fever virus (CCHFV) causes Crimean-Congo hemorrhagic fever (CCHF), a widely distributed disease with significant morbidity and mortality. The virus has high genetic diversity correlated with geographic distribution but limited temporal evolution within regions. Despite this, cases of CCHF within a region present as a spectrum of disease from often unrecognized asymptomatic infections to severe, fatal viral hemorrhagic fever, suggesting host factors may play a role in disease outcome. We investigated the effect of host genetic diversity on the outcome of CCHFV infection in the genetically diverse Collaborative cross (CC)-mouse model. Infected mice recapitulated the full spectrum of disease recognized in humans, and similar to human disease, virus replication, t
