We study theoretically the effect of both polar and dipolar active forces on the flow profile around $\\pm 1$ defects and their interaction in the presence of both viscosity and frictional dissipation. The vorticity induced by the active stress is non-zero at the $+1$ defect contributing to the active torque acting on the defect. A near-core flow reversal is predicted in absence of hydrodynamic screening (zero friction) as observed in numerical simulations.
