A Missouri woman died June 23 after contracting a rare tick-borne illness called Bourbon virus. Tamela Wilson, 58, was the first person to test positive for the virus in Missouri, and is only the fifth confirmed case since it was identified in 2014, CBS reported. Wilson, who worked as a superintendent at Meramec State Park in Missouri, fell in ill shortly after she pulled two ticks off her body in May. CBS reported that Wilson's doctor initially diagnosed her with a urinary tract infection and prescribed her antibiotics, but her condition continued to deteriorate.
