New data released by the CDC
on Thursday shows that 288 cases of measles have been reported in the
US since the beginning of the year—a higher number than those seen in
the first five months of any year since 1994. More than one in seven of
this year's cases resulted in hospitalization.
As assistant surgeon general Dr. Anne Schuchat explained, "The
current increase in measles cases is being driven by unvaccinated
people, primarily U.S. residents, who got measles in other countries,
brought the virus back to the United States and spread to others in
communities where many people are not vaccinated." Several of the cases
occurred after US residents traveled to the Philippines, where there has
been a measles outbreak since October 2013.
According to the
CDC press release, "90
percent
of all measles cases in the United States were in people who were not
vaccinated or whose vaccination status was unknown. Among the U.S.
residents who were not vaccinated, 85 percent were religious,
philosophical or personal reasons."
The data adds fuel to the ongoing debate about vaccines: though research from around the world consistently shows that
vaccines work, some doctors
continue to support opting out of immunizations, and in some states, more than
five percent of kindergartners have nonmedical vaccine exemptions.
