That is a lot of skin growths. My veiled chameleon's has papillomavirus, which appears as warty growths. He has less than 10 growths but it could certainly cause more, although they are not painful. A poxvirus can also cause many warty skin growths. It could also be a fungal or bacterial infection spreading over the skin. To know which one it could be a vet will need to do diagnostics. Probably an impression smear to look for bacterial or fungal organisms under the microscope, or a skin biopsy to see what is growing in the skin or if a virus can be detected. Whatever it is the sooner the better because if it's infection it can get very serious (as in potentially life-threatening) very quickly.
