Coronavirus vs Measles

I just read some interesting facts about coronavirus in the NY Times. Coronavirus can only travel about 6 feet from an infected person and it is unknown how long it can live on surfaces. Measles virus can spread up to 100 feet and survive on surfaces for hours. Which do you think is more contagious? And which can we prevent? Immunizations are effective. Immunizations are safe. Immunizations save lives. Immunizations cause adults.
