No. Though measles contains an RNA genome like retroviruses, it does not have the distinctive enzyme reverse transcriptase, and therefore does not change its genome to DNA before transcription.
Most likely not because a woman had cow pox in an experiment and was then given the small pox disease and never got it. Wow i did learn something from my Honors Biology teacher.
The measles is caused by a type of virus called Paramyxovirus. It is spread through the tiny droplets that may spray into the air when a person carrying the virus sneezes or coughs.
