title: Transmission and distribution of African horse sickness virus serotypes in South African zebra.
abstract: The prevalences of African horse sickness (AHS) virus serotypes in zebra foals from the Kruger National Park, South Africa were examined for possible associations between serotypes. Serotypes known to cross-react were combined for analysis. The distributions of serotypes between zebra were not always independent; in 7-8 month old zebra positive pairwise associations were observed between 3 serotypes. This could be generated by biological interactions between serotypes or heterogeneity in host-vector transmission. The data were also used to estimate the basic reproduction number, R0. For AHS virus overall, estimates of R0 ranged from 31-68. This underlines the need for a better understanding of serotype transmission and interactions in AHS.
