Climate or host availability: what determines the seasonal abundance of ticks?

abstract：:Schistosomiasis has been incriminated in the significant increase in hepatitis C virus (HCV) infections, although the association has not been adequately explained. We hypothesized that the CCR5Δ32 mutation may be involved in the high prevalence of HCV with schistosomiasis. The aim was to explore the association betwe...
