“A South Carolina measles outbreak has grown to 16 cases, including five from schools with low vaccination rates, state health officials said Oct. 14. The South Carolina Department of Health first identified the outbreak of the highly contagious viral disease in the state’s Upstate region in early October. A dozen cases have been concentrated in Spartanburg County, where two elementary schools have nearly 140 students quarantining at home because they weren't vaccinated against measles. Some cases have been related to travel or through close contacts of known cases. Others have no known source, which state health officials said suggests ‘measles is circulating in the community and could spread further.’”
One charter school in South Carolina's Upstate region had an immunization rate at just 17%, according to state health data.
