Abstract
Several deep surveys have been performed at 7 and 15 μm by using the mid-infrared camera ISOCAM on board the ISO satellite. We review their first results, emphasizing on the excess detected in the 15 μm counts with respect to the predictions of models with a mild evolution that is sufficient to explain the IRAS counts. We point out that a large fraction of the past star formation history is missed when studied using UV/visible data only.
