Thanks to global vaccination efforts, fairly low; thanks to anti-vaccination efforts, higher than they should be.
There have been 188 cases of measles in the US this year.
Why get vaccinated? Before the U.S. measles vaccination program started in 1963, about 3-4 million people in the U.S. got measles each year; 400-500 of them died, 48,000 were hospitalized, and 4,000 suffered encephalitis (brain swelling) due to measles. Widespread use of measles vaccine has led to a greater than 99% reduction in measles cases in the United States compared with the pre-vaccine era.
However, in 2008, 2011, 2013 and 2014, there were more reported measles cases compared with previous years. CDC experts attribute this to outbreaks of measles occurring in countries to which Americans often travel because each year unvaccinated travelers get measles while abroad, then bring the virus back to the U.S. There was also more spread of the measles virus in recent years since individuals who opt out of vaccine tend to cluster in groups. These groups of susceptible individuals then accumulate and age over time. This makes them susceptible to outbreaks when someone brings the virus into the group from abroad.
