In 2000, the United States declared that measles was eliminated from this country. The United States was able to eliminate measles because it has a highly effective measles vaccine, a strong vaccination program that achieves high vaccine coverage in children and a strong public health system for detecting and responding to measles cases and outbreaks.
Measles elimination is defined as the absence of continuous disease transmission for 12 months or more in a specific geographic area. Measles is no longer endemic (constantly present) in the United States.
As always, someone has to do the thinking part for you.
