A total of eight susceptible contacts were identified throughout this outbreak.
Seven contacts (88%) were located in the elementary school and one (12%) was in
the middle school. All susceptible contacts were verified as unvaccinated due to
religious exemptions and were immediately excluded from school. (A religious
exemption in Kansas is defined as a written document stating that the parent’s
objection to immunization for religious reasons exempts the parent and child
from state vaccination requirements.)
