We have studied the consequences of long-range interactions for the properties of the quasiparticles in the quantum Hall effect. We find that the quasiparticle states have long-range tails in their current and density distributions. These tails are an effect of Landau-level mixing and are absent if the state space is restricted to the lowest Landau level. We also discuss a violation of the spin-statistics relation for the quasiparticles.
