...In America, for example, measles stands as a stunning example of how the "anti-vaxxers" have united to helped bring back a disease we thought we had consigned to the dustbin of history. Three generations ago, uncontrolled annual epidemics of
measles infected three million to four million Americans annually. Victims typically suffered a painful itching, sometimes scarring rash, accompanied by fever and diarrhea. Severe cases led to pneumonia or encephalitis. In bad years, as many as 48,000 American children were hospitalized, 4,000 contracted encephalitis, and 450 died.
Beginning in the mid-1960s, an effective measles vaccination was mandated for American schoolchildren, and the disease was brought to heel. By 2000 the U.S. Public Health Service proudly declared that measles had been eliminated in the United States.
But this year, a scant two decades after we declared final victory, sustained "anti-vax" pressure on young parents has brought measles back with a vengeance, with 372 cases confirmed in 2018. So far through Feb. 10, 2019, already over
250 cases have been reported, almost all in children who have not been vaccinated. The problem is not confined to the U.S., as measles cases have also seen a
30% annual increase globally.
