In the US, a disease is transmitted through contact with certain animals or insects. This condition is typically found in the south-central region. It can be spread by flies or ticks that have bitten infected mammals.

The disease is not highly contagious, as it does not spread from person to person. Fewer than 200 cases are reported annually, usually between May and September. Further information about this condition, including its rising incidence, is available from the Centers for Disease Control and Prevention and other news sources.
