Congratulations, vacctivists, for ruining your kids' weekends by causing them to get the measles!
The Centers for Disease Control has issued an official health warning as the number of measles outbreaks in the US has reached its highest level since 1996. Cases have mostly been linked to travel to or from or immigration from countries with higher incidence of measles, or to exposure to someone in those groups.
But. 85% of the 156 cases the CDC has reported so far this year have been unvaccinated or no vaccination documented. The same ratio holds for immigrants/travelers to the US and US residents. So as much as you might want to blame the sickly foreigners, it's your own damn vacctivism that's doing it.
