Quite. I was confused when I saw the post because I remember recent outbreaks in the US...

The state of Arizona is currently reporting the US's biggest measles outbreak of 2016, with more than 22 confirmed cases in the state since May.
That might not sound like a lot, but before that there had only been 19 measles cases reported in the entire country this year - so the outbreak has effectively doubled the incidence of the disease.
If the outbreak gets worse, health officials will likely ask the governor of Arizona to declare a state of emergency, Samantha Olson reports for Medical Daily.
...but...
In fact, measles was officially eliminated from the US in 2000, which means it no longer occurs naturally within the country's borders.
But it can still be brought in from travellers overseas, and due to a recent drop in immunisation rates - thank you anti-vaxx movement - there have been several outbreaks over the past few years.
Could we see unvaccinated people being refused entry? Is that feasible?
