Many plants with fuzzy foliage have that reputation. Air movement is the factor on which I would focus. There's usually much less of it inside. The movement of air would cause leaves to dry more quickly. If concerned, put a fan blowing gently on plant after watering, &/or run a ceiling fan.
Surface pathogens that can be airborne are another. In the rain outside, surface pathogens would be much more likely to be knocked/washed off, vs. watering or misting inside where pathogens that have come to rest on a leaf (or possible contamination from the watering/misting device) might be aided by being merely moistened instead of being knocked off of leaves - like pushing a start button.
Another factor that could come into play is that a plant in a permanent location outside would usually arrange its' leaves so that they shed water. Less than optimal conditions inside like not quite enough light, &/or from having light coming from only 1 direction can cause leaves to be positioned such that water doesn't run off as readily, if it aids the leaves in exposing more surface area to more light (or, in more rare cases, to expose less surface area if in a more bright than optimal spot.)
