FIG 6.

Levels of lumpy skin disease viral DNA in blood or skin are proxy measures of infectiousness. Each plot shows the dose-response relationship between the probability of an insect being positive for lumpy skin disease virus (LSDV) DNA and the level of viral DNA in the blood (log₁₀ copies/ml; red) or skin (log₁₀ copies/mg; magenta) of the calf on which they fed. Four species of insects, namely, Aedes aegypti (first column), Culex quinquefasciatus (second column), Culicoides nubeculosus (third column), or Stomoxys calcitrans (fourth column), were tested at 0, 1, 2, 4, and 8 days postfeeding (rows). Plots show the observed proportion of positive insects (blood, red up triangles; skin, magenta down triangles) and the estimated probability of an insect being positive (posterior median [line] and 2.5th and 97.5th percentiles of the posterior distribution [shading: blood, red; skin, magenta]).
