Utah's measles outbreak has infected hundreds of people since January, with over 440 cases diagnosed and nearly 100 in the past three weeks. The state's Department of Health and Human Services has not mentioned the outbreak on social media or on its website since it began. This is only the second largest in the nation, followed by South Carolina, which has organized mobile vaccine clinics, brought in outside public health experts, and staged weekly public briefings. Meanwhile, South Carolina's outbreak has seen significant decrease in new diagnoses since early February, while the disease has surged in Utah. The outbreak is centered in southwest Utah, where there are over 200 cases.
