The vet must have done a choanal or cloacal swab and had it tested for aspergillosis based on clinical signs of the disease (the most common form is respiratory) plus blood work that does not show bacterial infection (if the bird looks and acts sick but the white blood cell count is normal or very slightly elevated, a fungal infection is suspected). The severity of the infection is determined by the elevation of titers (the higher the number, the worse the infection) BUT one needs to be careful with aspergillomas because they kind of screw up the diagnostic tools (did the vet take XRays?).
Now, healthy and happy birds do not get aspergillosis. Aspergillus is everywhere in nature; it's one of the most ubiquitous fungi there is... it's in the air, on our clothes, on the floor, the walls, everywhere. But a healthy immune system will prevent people and animals from getting the infection so only birds that have a depressed immune system do - and a depressed immune system means stress which can be physical (chronic liver or kidney problems, subclinical bacterial infections, depletion from overbreeding, bad diet, etc) or emotional (a bird that is not kept to a strict solar schedule, is alone and neglected, over trained -the famous Alex lived with the chronic form of it from the stress of training, etc.)
I don't know whether the vet gave you an antifungal or not, most vets would (the most common been itraconazole) along with some wide spectrum antibiotics (for secondary infections that might crop up so the immune system doesn't have to put 'any effort' into fighting them) but the most important thing is to keep the bird as stress-free as possible and, personally, I would give it some immune system boosters, too -because, what the heck, they can't hurt and they might help a bit, right? So, a good fresh food diet, a strict solar schedule, good quality full spectrum light, peace and quiet (grays are very high-strung birds and do not benefit from hullabaloo), lots and lots of out of cage time as well as one-on-one time, no training (I would NOT do any training whatsoever until the titers are down to zero), no outings, no strangers, no nothing that might upset or startled him in any way because the chronic form of the disease is quite deadly so your goal right now should be to eradicate it. Plenty of time for all the 'goodies' after he is healthy.
