According to a report from the Centers for Disease Control and Prevention (CDC), there were over 4,000 mumps cases in the USA in 2016. Mumps outbreaks may be the new normal thanks to clusters of unvaccinated kids.

The mumps vaccination program started in 1967 – before that there were about 186,000 cases reported each year (and that number might be low because of underreporting). Once mumps vaccinations were commonplace, the incidence of the disease fell by over 99%. For those who think that better sanitation or whatever caused decreases in diseases, I think that 1967 is fairly recent, and it’s clear that the vaccine itself started the precipitous drop in mumps outbreaks. Since the start of the vaccine era, annual mumps cases in the USA hovered below 1,000 during most years. But over the last 10 years, there has been a noticeable uptick in annual cases, with a high of over 6,000 cases in 2006.

Let’s examine the mumps outbreaks and see what may be the cause. Spoiler alert – expect Andrew Wakefield’s name to appear.
