In a cosmological context dust has been always poorly understood. This is true also for the statistics of Gamma-Ray Bursts (GRBs). We therefore started a program to understand the role of dust both in GRBs and as function of z. We present a composite model that considers a rather generic distribution of dust in a spiral galaxy and considers the effect of changing some of the parameters characterizing the dust grains, size in particular. Computations from this model of GRBs missed by dust absorption agree with the hypothesis of host galaxies with an extinction curve similar to that of the Small Magellanic Cloud, but the host cloud could be characterized also by dust with larger grains. Unfortunately, the present statistics lack significance, being based on incompatible observations, at different times from the burst and with different limiting magnitudes. To confirm our findings we need a set of homogeneous infrared observations. The use of forthcoming dedicated infrared telescopes, like REM, will provide a wealth of new afterglow observations.
