A quasi-particle description has been proposed to interpret recent lattice data on (2+1)-flavour hot QCD equation of state (EOS). The description is based on mapping the non-ideal (interacting) part of the EOS in to effective fugacities for quasi-gluons and quasi-quarks. As implications of the model, we study, a Virial expansion for hot QCD which highlights the role of interactions, and temperature dependence of the bulk viscosity.
