Approximately 85 cases of chicken pox have been reported in Vigo County making it the largest outbreak of chicken pox in the country.
Health officials are worried that as many as 100 kids could be infected by the end of the week.
Sydney Elliott with the Vigo County Health Department says a lot of the children coming down with chicken pox were vaccinated, but occasionally a strain of the chicken pox virus can mutate, rendering the vaccine a lot less effective.
Elliot says the outbreak isn‘t contained to Vigo County either, several cases in Parke County have also been reported.
