Vaccine-Exempt Students Behind N.C. Chickenpox Outbreak

North Carolina's largest chickenpox outbreak in decades is centered in a primary school with a large number of vaccine-exempt students, according to health officials.

Thirty-six students at Asheville Waldorf School were diagnosed with the disease last Friday, BBC News reported.

The school has one of the state's highest rates of religious-based vaccine exemptions for students.

Of the school's 152 students, 110 have not received the vaccine against the virus that causes chickenpox, according to BBC News.

In 2017/18, nearly 68 percent of the school's kindergarten students had religious immunization exemptions on file.

"This is the biggest chickenpox outbreak state health officials are aware of since the vaccine became available," a state health department spokesman told BBC News.

The school is co-operating with local health officials and is compliant with all state laws, a school spokesperson said.

CDC Creates Task Force to Track Polio-Like Disease

A task force to investigate a rising number of cases of a rare polio-like disease among children in the United States has been created by the U.S. Centers for Disease Control and Prevention.

The task force on acute flaccid myelitis (AFM) will include scientific, medical and public health experts who will attempt to identify the cause of the disease and improve patient treatment and outcomes.

AFM affects the spinal cord, causing weakness in one or more limbs. The United States has seen an increased number of AFM cases since 2014, mostly in children. There have been 106 confirmed cases of AFM in 29 states in 2018. All but five have been in children aged 18 or younger, according to the CDC.

"This task force will ensure that the full capacity of the scientific community is engaged and working together to provide important answers and solutions to actively detect, more effectively treat, and ultimately prevent AFM and its consequences," CDC Director Dr. Robert Redfield said in an agency news release.

The task force will make key recommendations on how to respond to the rising number of AFM cases.

The task force plans to submit its first report at a Dec. 6 public meeting in Atlanta, the CDC said.
