Help!!!

My zucchini is dying and I have no idea why.It started to wilt 3 days ago and I thought it was from the heat so I watered it. Today when I got home from work it was almost completely wilted and turning yellow. Up until a week ago it was perfectly healthy and producing on a regular basis. The weather around here has been very rainy and hot. Its literally been raining almost every other day and its been a good amount of rain. Is it possible that it become sick with some kind of mold? can this affect my other plants and what can I do to stop it from spreading if this is the case? I have 2 yellow squash plants that are perfectly fine. Also, if I buy a zucchini plant from Home depot that is about 6 inches tall approximately how long would it take to produce? I live in Charlotte, NC if that's of importance. Thanks in advance :)
