Tiny spots on my pictures. Any ideas?

Text:

I am suddenly getting very fine "measle-like" spots on all my images that go across the entire picture plane. This is especially prevalent when I shoot at higher f stops. The spots seem to concentrate in the center field of vision and become prevalent at f11 and up and very noticeable at f22 and up. I checked for dead pixels and find that there are none. I took photos with multiple lenses. I took to camera shop and had CCD professionally cleaned. I tried shooting with both Long exp. NR and high ISO NR in Normal, OFF, or ON positions and the results were the same. The "specks" are very fine and number in the hundreds. They almost look like "noise" and are too fine to be dust. They are very prevalent at 100%.
 
Neither the camera shop nor the techies had seen this problem before. Any ideas?

It's like there is a shotgun pattern of micro spots in the center of the sensor. It just happened suddenly and no one can explain it.
