Importation Into the United States from Africa of Rhipicephalus Simus on a Boutonneuse Fever Patient

Abstract
Rhipicephalus simus Koch was removed from a human upon his return to Connecticut, U.S.A. from Kenya, Africa. This person became ill in Africa, exhibited clinical manifestations of boutonneuse fever and had a significant rise (≥8-fold) in IgM titer against spotted fever-group rickettsiae. Rickettsia conorii was probably the infectious agent.
