FIG. 1.

Viremia profile of vertebrates exposed to African swine fever virus. Viremia profiles of three vertebrate species exposed to African swine fever virus through intramuscular inoculation, intranasal infection, direct and indirect exposure between infectious pigs is visualized from 14 studies that documented viremia with HAD₅₀ and HA (Wilkinson et al. 1981, McVicar 1984, Villeda et al. 1993, Ramiroibanez et al. 1995, Anderson et al. 1998, Argilaguet et al. 2012, Karalyan et al. 2012, Guinat et al. 2014, O'Donnell et al. 2015a, 2015b, 2016, Carlson et al. 2016, Sanford et al. 2016, Popescu et al. 2017). Studies quantified viral titers postinfection with HAD₅₀ and HA, which are assumed to be equivalent measures of viral titer (Johnston et al. 1992). Vertebrate infectiousness depends on the magnitude of infection (y-axis) and the duration of infection (x-axis). Time series data on viremia titers ended when animals cleared infection (0.0 log₁₀ HAD₅₀/mL), animals died from infection (*), or were euthanized (⋄). HA, Hemagglutinin Assay; HAD₅₀, Hemadsorption in 50% of inoculated cells.
