Seoul virus (SEOV) is a worldwide ratborne orthohantavirus. We describe an SEOV infection in an adult returning to France from Kenya, followed by Guillain-Barré syndrome. We confirmed SEOV infection by PCR and sequencing. Although transmission might have occurred in Kenya, the epidemiologic information available is not sufficient to confirm that possibility.
