South Carolina measles outbreak grows by nearly 100, spreads to North Carolina and Ohio

The outbreak centered in Spartanburg County grew to 310 cases over the holidays, and spawned cases in North Carolina and Ohio among families who traveled to the outbreak area in the northwestern part of the state. State health officials acknowledged the spike in cases had been expected following holiday travel and family gatherings during the school break. A growing number of public exposures and low vaccination rates in the area are driving the surge, they said.
