  The second-order hydrodynamic equations for evolution of shear and bulk
viscous pressure have been derived within the framework of covariant kinetic
theory based on the effective fugacity quasiparticle model. The
temperature-dependent fugacity parameter in the equilibrium distribution
function leads to a mean field term in the Boltzmann equation which affects the
interactions in the hot QCD matter. The viscous corrections to distribution
function, up to second-order in gradient expansion, have been obtained by
employing a Chapman-Enskog like iterative solution of the effective Boltzmann
equation within the relaxation time approximation. The effect of mean field
contributions to transport coefficients as well as entropy current has been
studied up to second-order in gradients. In contrast to the previous
calculations, we find non-vanishing entropy flux at second order. The effective
description of relativistic second-order viscous hydrodynamics, for a system of
interacting quarks and gluons, has been quantitatively analyzed in the case of
the $1+1-$dimensional boost invariant longitudinal expansion. We study the
proper time evolution of temperature, pressure anisotropy, and viscous
corrections to entropy density for this simplified expansion. The second order
evolution of quark-gluon plasma is seen to be affected significantly with the
inclusion of mean field contributions and the realistic equation of state.
