Likely, yes. It does depend on the fungus, though. It looks a lot like watering damage, too. Overwatering will cause wilting like this. It is very important to make sure that the soil is allowed to dry out down to a few inches, thoroughly, between waterings. This will help cut down on infections, as well.
At this time, I would treat with a fungicide. Copper based fungicides are better choices.
