The damping rates of ultrasoft quarks are determined in the context of next-to-leading order hard-thermal-loop summed perturbation of high-temperature QCD. Three types of divergent behavior are encountered: infrared, light-cone and at specific points determined by the gluon energies. Only the infrared divergence persists and is logarithmic.
