After a widespread vaccination campaign, the United States declared measles eradicated in 2000.
Eradicating the disease capped off a decades-long mission.
Starting the program in 1963, the U.S. would have 3 to 4 million residents diagnosed with measles every year. After 37 years, the U.S. met the CDC’s standards for eradication: no transmission of measles for one year.
But, the fight against measles doesn’t end when the CDC declares elimination.
A country needs to maintain the fight against this disease and continue widespread vaccinations. For various reasons, this proved problematic across the country.
