The North Carolina school with a large anti-vaccination community is at the heart of the biggest decline in the bird ball in decades, officials say.
On Friday, 36 patients were diagnosed with Asheville Valdorf's school, according to the magazine Asheville Citizen-Times.
The school has one of the highest rates of religious liberation of the state, allowing students to skip vaccinations.
US health officials have said that vaccinations are far more secure than spraying.
"This is the biggest epidemic of the oncotic occurrence of innocent state health stars from everything that the vaccine has become available," the spokeswoman of the North Carolina Ministry of Health said in a statement via e-mail.
Of the 152 pupils from Valdorf's School, 110 did not receive a vaccine for a varicella virus, most known as Norfolk, found Civic-Times.
And 67.9 percent of students in kindergarten had exemptions from religious immunization in the school year 2017-2018, according to data from the state.
The primary school cooperated fully with local health officials and was in compliance with all laws in North Carolina, a spokesman for the school said.
"We think that our parents are highly motivated to choose exactly what they want for their children. We, as a school, do not discriminate on the basis of a child's health or health status."
Buncombe County, the home of Asheville, with a population of over 250,000, has the highest rate of religious immunization in the country's liberation.
Local health officials are closely monitoring the situation, the county health department said.
"We want to be clear: Vaccination is the best sheep protection," states Dr County Medical Director Dr Jennifer Mullendore.
"When we see a large number of uninvited children and adults, we know that a disease like sheep's walnuts can easily spread throughout the community – to our playgrounds, grocery stores and sports teams."
The North Carolina Law requires certain immunizations, including spasms, blood vessels and baby nursing mothers, but the state allows health and religious liberation.
Most religions do not forbid vaccinations, but in recent years some American parents have been frightened of adverse reactions to vaccines.
While some of the bad reactions, such as allergies, are possible for vaccines, the medical community has uncovered the vast majority of these fears, and groups, including the World Health Organization and the American Academy of Pediatrics, are encouraging vaccinations.
What is the goddess?
Sheep's storm is a viral infection that causes a blistering rash, itching and fever. In severe cases, complications such as inflammation of the brain, inflammation of the lungs and death may occur.
The virus spreads through contact or coughing and killing, although it is not as infectious as smallpox, which can spread without contact.
