The Centers for Disease Control (CDC) are testing ticks collected at Meramec State Park for the Bourbon virus.
The Missouri Department of Health and Senior Services (DHSS) was notified by the CDC that a Missouri resident has tested positive for Bourbon virus infection after visiting the state park earlier in the week.
The case did not involve any travel outside of the state, indicating that exposure occurred in Missouri.
According to the Missouri Department of Natural Resources, the Bourbon virus is a rare tick-borne illness that has been found only four times in the United States.
Staff of the Franklin County Health Department teamed the CDC to collect tick samples at the park in Sullivan.
Bourbon virus testing is only available from CDC in certain circumstances and is still in the beginning stages of development.
