Thats like the a.i.d.s. of the reptile world but it's only passed on with contact from infected animals. Have you gotten any new animals or been somewhere in contact with them? Thats why shows always have germ-x gel. As far as mites......just PAM the hell out of them, works everytime. The star gazing is something one of my morphs has been doing since I've had him and he is fine. Just remember....When in doubt, take them to the vet.
